HOUSING COMPLIANCE PROJECT PROPOSAL
The City of Tigard proposes legislative amendments to the Tigard Community Development
Code (TCDC) and the Zoning Map.
STAFF REPORT
Sr. Planner Schuyler Warren introduced himself and noted that the purpose of the hearing was
for the Planning Commission to consider a recommendation to the City Council on proposed
text amendments to the Tigard Community Development Code and proposed map
amendments to the Tigard Zoning Map. He continued saying that these amendments will bring
May 2, 2022 Page 2 of 5
the city into compliance with state law related to housing. He went through a PowerPoint
(Exhibit A) detailing the project. He provided the background and history of Tigard’s housing
policy work as he went through each year that changes took place to the housing policy. In
2017, the Oregon Legislative Assembly passed Senate Bill 1051. This was the first of a series of
housing-related bills that change the way that housing is provided for in our city and across the
state. This bill required cities to legalize accessory dwelling units in all zones, and the bill
changed the definition of needed housing in state law to include “all housing.” He said that
while this may seem like a small change, it had a major impact on the way we process and review
housing development proposals, because by state law, a city must apply only clear and objective
standards to needed housing.
The City of Tigard used the opportunity presented by SB1051 to make housing policy updates
in line with the adopted recommendations of the city’s most recent housing needs analysis,
which was completed in 2013. The Phase II Housing Options Project included a number of
changes, including the legalization of middle housing like cottage clusters, the removal of
language reflecting housing tenure from the code, and allowances for up to two Accessory
Dwelling Units (ADU’s) per lot, with duplexes and triplexes folded into the definition of ADUs.
Following quickly after Tigard’s action, the Oregon Legislative Assembly again acted to expand
housing opportunity across the state. House Bill 2001 legalized middle housing across the state
and required that cities of Tigard’s size come into compliance within 30 months. At that time,
the city was largely in compliance with the terms of the bill, but there were administrative rules
to follow. While the state was working on HB2001, Tigard continued to move housing policy
forward by adopting the city’s first Affordable Housing Plan. This set-in place a roadmap for the
creation of stable funding streams and a set of prioritized programs and policies.
The administrative rules associated with HB2001 were adopted by the Land Conservation and
Development Commission in late 2021. While the city had been compliant with the bill, the
rules were far more detailed and prescriptive in nature, so city teammates set about auditing the
code and working with staff at the Department of Land Conservation and Development to
determine what, if any, changes would be needed. At that point, we believed the city would be
able to avail itself of the alternative compliance process that was set out in the bill given the
early and significant work in forwarding housing policy. In April of 2021, we received word that
alternative compliance would not be possible, so we set out to scope a project to make necessary
updates to the Community Development Code to meet the requirements of state law.
While that work was occurring, the Legislative Assembly acted once again in the 2021 session,
passing Senate Bill 458. This bill requires that the middle housing developments allowed under
HB2001 must be eligible for middle housing land divisions. These divisions, which are
processed locally, create discrete units of land that can be transferred by deed, although the
overall development must continue to comply with the middle housing development regulations
in place.
This Planning Commission hearing on this work is to bring the city’s Development Code into
compliance with state law and administrative rules. While the city is in compliance with the
broad provisions of HB2001, we do need to make some updates. We also want to bring the city
into compliance with the provisions of SB458 at the same time. We want to make some small
May 2, 2022 Page 3 of 5
changes that will improve the efficiency and effectiveness of the code and provide even more
housing opportunity for Tigard’s current and future residents.
Thematically, this compliance project has three major components. The first is an update to the
processes used to approve housing development. In general, we will need to approve middle
housing developments without a land use process involved where a development can meet clear
and objective standards. In addition, we need to make some updates to our standards as they
apply to certain middle housing types. And then finally, we are capping this work with a
simplification and streamlining of our residential zones. Given the many changes in state law,
and the requirements that we allow middle housing in all zones at the same densities, and with
the same opportunity as is available to single detached houses, Tigard’s eight residential zones
have become more indistinct.
At this point, Schuyler took the commissioners through many topics outlined in the PowerPoint
(Exhibit A) ending with what remains to be done after the changes.
STAFF RECOMMENDATION
Staff recommends the Planning Commission find in favor of the proposed amendments with
any alterations as determined through the public hearing process and make a final
recommendation to the City Council.
QUESTIONS
There were some general informational questions. There was a question about how code is
written. Assistant Community Development Director, Tom McGuire noted that as a rule of
thumb, when writing code, they try to write an 80/20 code which means they try to cover at
least 80% of the situations they would likely run into. He said you never can write code that
covers 100% of every situation. There were several other general questions that didn’t pertain to
the case in point but were just general questions. One commissioner said he had spent several
hours looking for definitions of zoning codes and not getting them. He suggested that the city
have outside of the code some sort of a publicly facing informational sheet that gives a quick
summary description of what each of the zones are about. He said he had typed into the City’s
Website the keywords “zoning codes” looking for lists, maps, or definitions of the zoning codes
but found none. Tom McGuire said that a quick informational page could be done to help
people understand. He also noted that there is a “Zoning 101” website linked on the City of
Tigard webpage:
English: https://www.youtube.com/watch?v=LHXKCDVWg2c&ab_channel=CityofTigard
Spanish: https://www.youtube.com/watch?v=5HPkA4w5sOk
Regarding edits that had been sent to Schuyler, Tom wondered whether the Planning
Commission should move to approve and adopt the edits that both President Hu and Vice
President Jackson had submitted. President Hu noted that his edits were not really substantive;
just scrivener’s errors for the most part. Vice President Jackson noted that the vast majority of
his were also simply scrivener’s errors. Tom asked Vice President Jackson if he was comfortable
with trusting the staff to make the edits to the next draft that would go to the City Council. V ice
May 2, 2022 Page 4 of 5
President Jackson said that based on the response he received from Schuyler earlier, he was fine
with that.
TESTIMONY IN FAVOR OF THE APPLICATION
None.
TESTIMONY IN OPPOSITION TO THE APPLICATION
None.
DELIBERATION
President Hu asked the commissioners to deliberate and make any comments they’d like to
make before the actual vote.
Commissioner Miranda thanked Schuyler Warren for his hard work on this project. She said
she felt comfortable with this and the briefing beforehand.
Commissioner Schuck is good with the discussion. He said he was uncomfortable about just
one thing Tom had mentioned briefly earlier – that is the idea of pulling back a permit that’d
been approved – that was the only one that caused him a bit of grief. He noted, “It’s a
complicated code so the applicant could come in thinking they understand it, and the city thinks
they understand it, and it seems that if there’s some sort of a mistake or accident in there and
someone goes forward with a project… you’d hate to pull it back. But again, it probably falls
within the 80/20 rule that you mentioned and is probably not typical.”
Tom replied, “Essentially what we’ve done is we’ve taken the process that we are presently
doing now, and have done for many years, and just put it into words. The plan check process
has never been written down in the code, so we felt that at this point, given where state law is
going, we just need to codify what we’re already doing. If somebody gave us bad information…
for instance, they’ve given us a set-back that doesn’t match what’s at the site - and the building
inspector finds that - we have the right to revoke the permit; however, what we usually do is
work with them to make a satisfactory change so that they can continue with their project. This
is not a scary new thing that we’re doing; this is just putting into words in the code our current
practice.” Commissioner Schuck said, “That makes sense and is perfectly reasonable. Thank you
for the excellent clarification”.
Commissioner K7 said he appreciates the hard detailed work that had been done by staff and
he also wanted to give a shout out to Vice President Jackson for having the tenacity for finding
and correcting the smallest things in very large documents. Excellent job!
President Hu thanked Schuyler and his team for their hard work on this major project. He
thinks this amendment shows that the Tigard Code is already ahead of the curve and the state is
finally catching up. He hopes this will offer greater flexibility to housing development, and
partially address the housing and affordability issues in the city.

Staff recommends the Planning Commission find in favor of the proposed amendments (Attachments 1 and 2)

Tigard City Council.
SECTION III. BACKGROUND INFORMATION AND PROJECT SUMMARY
The Housing Compliance project builds on the City’s recent housing policy work, including the 2018 Phase II
Housing Options project and the 2021 Tigard Housing Needs Analysis. The main intent of this project is to
bring the City’s existing code into compliance with the provisions of House Bill 2001 (2019), the associated
Oregon Administrative Rules Chapter 660 Division 46 (2020), and Senate Bill 458 (2021).
House Bill 2001, passed a little more than six months after Tigard adopted its mid dle housing reform, provided
a broad requirement that cities over a certain size across the state must legalize middle housing. At the time of
its passage, the City was largely in compliance with the provisions of the bill. Two small changes were made in
a subsequent code project in 2019 that were intended to bring the City into full compliance. However, the bill
also mandated rulemaking and the creation of a Model Code that would be applied to middle housing
approvals in jurisdictions that could not or wou ld not adopt their own local regulations that met state
requirements. The administrative rules and model code were adopted in late 2020 and contain some differences
from what Tigard adopted in 2018.
The rules as published included an option for alternative compliance with the rules. The City met with the
Department of Land Conservation and Development over the course of the following four months to
determine if demonstrating alternative compliance was possible, given the City’s early and good-faith efforts to
implement middle housing reform before HB2001 was adopted. In April of 2021, DLCD completed a review
of the City’s middle housing code, and informed the City that alternative compliance would not be possible.
The Community Development department subsequently moved forward with scoping a project to bring the
City into compliance with the bill by the deadline of June 30, 2022. During the early stages of this work, the
legislature passed Senate Bill 458, which requires that the City allow middle housing land divisions on an
expedited basis. Tigard must comply with this requirement by the same deadline.
Bringing the City’s code into full compliance with the administrative rules also presented an opportunity to
revisit and improve the code based on the exp erience of implementing its provisions over the past three -and-a-
half years. Process improvements and small tweaks to standards were included in the project to ensure that
Tigard remains a leader in middle housing development and housing opportunity in gen eral.
The implementation of the state administrative rules means that middle housing must now be allowed on lots
that are the same size or smaller than the lots for single detached houses. As a result, the distinctions between
many of these zones have become trivial or moot . One example of this is the standards for rowhouses
(townhouses under the state’s nomenclature), which require that rowhouses be allowed on lots no larger than
1,500 square feet across all zones. This, and other requirements, have blurred the distinctions between zones.
HOUSING COMPLIANCE DCA2022-00001
5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 3 OF 12
Given the need to simplify standards and remove redundant or repetitive provisions in the code, the
Community Development team proposes to consolidate existing zones, reducing the total number of
residential zones from 8 to 5.
Summary of Code Changes
This section provides a finer level of detail of the changes proposed for each chapter of the revised development
code. Some types of changes are common throughout the code. These types of changes unify and standardize
the entire development code through using consistent phrasing, terminology, and formatting. These changes
include:
• The phrase “single detached houses” has been replaced with “small form residential.”
• The small form residential type integrates single detached houses, as well as duplexes and triplexes,
which are required to be allowed by right in all zones that allow a single detached house.
• The accessory dwelling unit type, which in the current code includes the duplex and triplex housing
types, has been reverted to solely applying to a detached accessory dwelling unit. Further, the attached
accessory dwelling unit type has been integrated into the small form residential housing type .
• Housing types that have more complicated development standards are provided with the state-
mandated clear and objective approval process without land use, as well as an alterna tive process that
allows greater design flexibility.
• The new Type II-Modified procedure for Sublot Plats requires updating references to Land Use
Procedures throughout the Community Development Code as well as a few references in the Tigard
Municipal Code.
• As part of the zone consolidation, residential zones have been renamed to remove numbers from their
designation. These numbers often caused confusion as they were assumed to relate to density. This
disjunction was made more confusing by the addition of middle housing, where each housing type
allowed in residential zones has a different net density, none of which corresponds to the numerical
designation of the zone.
Two new chapters have also been proposed: Chapter 18.805 Lot Standards and C hapter 18.840 Sublot Plats.
Chapter-specific changes are discussed below. If a chapter does not include significant changes it is included in
the omnibus changes section.
Chapter 18.20 Administration and Enforcement
This chapter is updated to provide clarity on the procedures used for plan review of development and use
proposals that do not require land use.
Chapter 18.110 Residential Zones
This chapter is updated to provide new use and housing type tables for the zone mergers. Th e density standard
is removed because it is duplicated elsewhere in the code.
Chapter 18.220 Accessory Dwelling Units
This chapter is updated to implement the changes listed in the summary above and remove the Type I approval
process for ADUs, instead allowing them by right when the applicable standards are met.
HOUSING COMPLIANCE DCA2022-00001
5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 4 OF 12
Chapter 18.240 Cottage Clusters
This chapter is updated to incorporate the requirem ents of state law and administrative rules related to siting
and design standards. In addition, some small changes are included that improve or clarify the meaning of
standards. The required clear and objective standards are included, as well as an alternative compliance pathway
that requires land use.
Chapter 18.250 Courtyard Units
While not subject to the requirements of state law and administrative rules related to HB2001, this chapter was
updated to provide design standards and approval processes consistent with the similar cottage cluster housing
type. In addition, some small changes are included that improve or clarify the meaning of standards.
Chapter 18.270 Quads
This chapter was updated to comply with state administrative rules, removing disallowed standards and the
requirement for land use approval. In addition, some small changes are included that improve or clarify the
meaning of standards.
Chapter 18.280 Rowhouses
This chapter was updated to comply wit h state administrative rules, removing disallowed standards and the
requirement for land use approval. In addition, some small changes are included that improve or clarify the
meaning of standards.
Chapter 18.290 Small Form Residential
This chapter is updated to implement the changes listed in the summary above and incorporate approval
processes and standards for single detached houses, duplexes, triplexes, and attached accessory dwelling units
into one chapter.
Chapter 18.710 Land Use Procedures
This chapter was updated to include a new Type II -Modified procedure for Sublot Plats.
Chapter 18.805 Lot Standards
This is a new chapter but consolidates development standards and provisions from other parts of the code,
including Residential Standards and Land Divisions.
Chapter 18.780 Site Development Review
This chapter was updated to make the language and approval process consistent with the new alternative
standards for some middle housing and to further clarify the meaning of the language.
Chapter 18.810 Lot Line Adjustments and Consolidations
Chapter 18.820 Land Partitions
Chapter 18.830 Subdivisions
HOUSING COMPLIANCE DCA2022-00001
5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 5 OF 12
These chapters were updated to make language and standards more consistent where applicable and to move
some standards to the new Lot Standards chapter, 18.840.
SECTION IV. APPLICABLE CRITERIA, FINDINGS, AND CONCLUSIONS
STATEWIDE PLANNING GOALS AND GUIDELINES
State planning regulations require cities to adopt and amend Comprehensive Plans and land use regulations in
compliance with the state land use goals. Because the proposed code amendments have a limited scope and the
text amendments address only some of t he topics in the Statewide Planning Goals, only applicable statewide
goals are addressed below.
Statewide Planning Goal 1 – Citizen Involvement:
This goal outlines the citizen involvement requirement for adoption of Comprehensive Plans and
changes to the Comprehensive Plan and implementing documents.
FINDING: The City conducted a comprehensive public engagement process with the 2018 Phase II Housing
Options project. This project brings those changes into compliance with state law.
Notice was sent to affected government agencies by email on March 18, 2022.
The notice requirements set forth in Section 18.710.110 (Type IV Procedures) were met. A notice was published
in the Tigard Times newspaper on April 15, 2022. A minimum of two public hearings will be held (one before
the Planning Commission and the second before the City Council) at which an opportunity for public input is
provided. A minimum of three drafts of the proposed code changes (Discussion Draft, Proposed Draft to the
Planning Commission, and Planning Commission Recommendation to City Council) will be made available to
the public for review prior to hearings and adoption. This goal is satisfied.
Statewide Planning Goal 2 – Land Use Planning:
This goal outlines the land use planning process and policy framework.
FINDING: The Department of Land Conservation and Development (DLCD) has acknowledged the City’s
Comprehensive Plan as being consistent with the statewide planning goals. The Development Code implements
the Comprehensive Plan. The Development Code establishes a pro cess and standards to review changes to the
Tigard Development Code in compliance with the Comprehensive Plan and other applicable state requirements.
As discussed within this report, the applicable Development Code process and standards have been applied to
the proposed amendment, and the intent of these amendments are to meet the requirement of state law,
administrative rules, and the Statewide Planning Goals. This goal is satisfied.
Statewide Planning Goal 10 – Housing:
This goal requires cities and counties to provide adequate capacity for needed housing. OAR Chapter
660 Division 8, which implements Goal 10, states that “the purpose of the division is to ensure
opportunity for the provision of adequate numbers of needed housing units, the efficient use of
buildable land within urban growth boundaries, and to provide greater certainty in the development
process so as to reduce housing costs.”
HOUSING COMPLIANCE DCA2022-00001
5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 6 OF 12
FINDING: The City adopted an updated Housing Needs Analysis in May of 2021. This analysis found that
the City will need to accommodate more than 7,400 new households over the coming 20 years. The City
currently only has the capacity for 4,200 units in existing areas and will need an additional 3,200 units of
housing to meet this need. Notably, the estimates of need are based on regional projections that do not account
for existing underproduction levels and the needs of the unhoused. A pilot regional housing needs analysis
conducted by Oregon Housing and Community Services shows a need of nearly 12,000 units in Tigard over
that same time horizon.
The proposed code changes do not decrease housing supply or capacity. They further Tigard’s work to support
more housing diversity and allow increased housing capacity in exchange for development of much-neeeded
smaller housing units. The clarification of standards and the new allowances for by-right development of Small
Form Residential (single detached houses, duplexes, triplexes, and attached accessory dwelling units),
Rowhouses, Quads, and Detached Accessory Dwelling Units will result in an easier development pathway for
these housing types.
These middle housing types allow for a more efficient use of land, particularly land that would otherwise be
marginally developable. Because of the more flexible development standards provided for middle housing,
larger lots that may be constrained by sensitive lands or topography can include housing in the developable
portions of the lot while protecting natural resources. Lots with these types of constraints may not be
developable for small form residential due to lot size and frontage requirements.
The City may only apply clear and objective standards to housing under Goal 10. These code changes include
further clarification of standards to ensure that they are as clear and objective as practicable . This goal is
satisfied.
CONCLUSION: Based on the findings above and the related findings below, staff finds the proposed code
amendments are consistent with applicable Statewide Planning Goals.
METRO’S URBAN GROWTH MANAGEMENT FUNCTIONAL PLAN
State planning regulations require cities within the Metro service area to adopt and amend Comprehensive Plans
and land use regulations in compliance with Metro’s Urban Growth Management Functional Plan. Because the
proposed Code Amendments have a limited scope and the text amendments address only some of the topics in
METRO’s Urban Growth Management Functional Plan , only applicable Titles are addressed below.
Title 1 – Housing Capacity
The Regional Framework Plan calls for a compact urban form and a “fair-share” approach to meeting
regional housing needs. It is the purpose of Title 1 to accomplish these policies by requiring each city
and county to maintain or increase its housing capacity except as provided in section 3.07.120.
FINDING: Title 1 has been met by further increasing the housing capacity in Tigard. Middle housing types
included in the proposed code changes provide for incremental capacity growth that is compatible with existing
neighborhoods. Each of the standards provided in 3.07.120 Housing Capacity sets minimum zoned capacity,
which is not affected by the proposed changes. In addition, the final standard states that a “city or county shall
authorize the establishment of at least one accessory dwelling unit for each detached single-family dwelling unit
in each zone that authorizes detached single-family dwellings.” The city’s development code exceeds this standard
by allowing up to two accessory dwelling units on each small form residential lot. This title is satisfied.
Title 6 – Centers, Corridors, Station Communities and Main Streets
HOUSING COMPLIANCE DCA2022-00001
5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 7 OF 12
The Regional Framework Plan identifies Centers, Corridors, Main Streets and Station Communities
throughout the region and recognizes them as the principal centers of urban life in the region. Title 6
calls for actions and investments by cities and counties, complemented by regional investments, to
enhance this role. A regional investment is an investment in a new high-capacity transit line or
designated a regional investment in a grant or funding program administered by Metro or subject to
Metro’s approval.
FINDING: The proposed code changes have little effect on the City’s adopted Town Centers – the
Downtown Plan District and the Tigard Triangle Plan District – because each of these districts already provide
for increased housing capacity through allowances for mixed-use and incremental development, as well as
increased height allowances. The City’s regional center – the Washington Square Plan District – already includes
allowances for most housing types. Section 3.07.640(c) of Title 6 states: “Centers, Corridors, Station
Communities and Main Streets need a mix of housings [sic] types to be vibrant and successful. The following
mix of housing types is recommended for each: (1) The types of housing listed in the “needed housing” statute,
ORS 197.303(1); (2) The types of housing identified in the City’s or county’s housing need analysis done pursuant
to ORS 197.296 or statewide planning Goal 10 (Housing); and (3) Accessory dwellings pursuant to section
3.07.120 of this chapter.” Unfortunately, many of the lands included in the MUR-1 and MUR-2 zones are
constrained by sensitive lands. Because missing middle housing t ypes can make more efficient use of constrained
lands by building around sensitive lands without regard to creating lots sized for small form residential, they are
an appropriate type for inclusion in these two zones. This title is satisfied.
Title 7 – Housing Choice
The Regional Framework Plan calls for establishment of voluntary affordable housing production goals
to be adopted by local governments and assistance from local governments on reports on progress
towards increasing the supply of affordab le housing.
FINDING: Title 7 has been met by further increasing the capacity for housing choice in Tigard. Section
3.07.730 of Title 7 states that: “cities and counties within the Metro region shall ensure that their comprehensive
plans and implementing ordinances: (a) Include strategies to ensure a diverse range of housing types within their
jurisdictional boundaries. (b) Include in their plans actions and implementation measures designed to maintain
the existing supply of affordable housing as well as increase the opportunities for new dispersed affordable
housing within their boundaries. (c) Include plan policies, actions, and implementation measures aimed at
increasing opportunities for households of all income levels to live within their individual jurisdictions in
affordable housing.” Title 7 does not specify what is meant by “affordable housing”. The City interprets the
mandate to include not just regulated affordable housing, but naturally -occurring affordable housing and housing
made affordable by a range of choices in size. The proposed code changes encourage greater housing diversity
and choice in Tigard, leading to more affordable choices for families and individuals, and ensuring opportunities
for affordable home ownership and rent al for all income levels and household sizes. This title is satisfied.
Title 8 – Compliance Procedures
A city or county proposing an amendment to a comprehensive plan or land use regulation shall submit
the proposed amendment to the COO at least 35 days prior to the first evidentiary hearing on the
amendment. The COO may request, and if so the city or county shall submit, an analysis of compliance
of the amendment with the functional plan. If the COO submits comments on the proposed amendment
to the city or county, the comment shall include analysis and conclusions on compliance and a
recommendation with specific revisions to the proposed amendment, if any, that would bring it into
compliance with the functional plan. The COO shall send a copy of comment to those persons who
have requested a copy.

5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 8 OF 12
FINDING: Notice and a copy of the proposed code amendments were provided to Metro on March 18,
2022. No comments were received.
CONCLUSION: Based on the findings above, staff finds that the proposed code amendment is consistent
with Metro’s Urban Growth Management Functional Plan .
TIGARD COMPREHENSIVE PLAN
State planning regulations require cities to adopt and amend comprehensive plans and land use regulations in
compliance with the state land use goals and consistent with their adopted comprehensive plan goals and policies.
Because the development code amendments have a limited scope and the text amendments address only some
of the topics in the Tigard Comprehensive Plan, only applicable comprehensive plan goals and associated policies
are addressed below.
Comprehensive Plan Goal 1: Citizen Involvement
Policy 1.1.2: The City shall define and publicize an appropriate role for citizens in each phase of the land
use planning process.
FINDING: The City conducted a comprehensive public engagement process with the 2018 Phase II Housing
Options project. The proposed amendments brings those changes into compliance with state law.
Notice was sent to affected government agencies by email on March 18, 2022.
The notice requirements set forth in Section 18.710.110 (Type IV Procedures) were met. A notice was published
in the Tigard Times newspaper on April 15, 2022. A minimum of two public hearings will be held (one before
the Planning Commission and the second before the City Council) at which an opportunity for public input is
provided. A minimum of three drafts of the proposed code changes (Discussion Draft, Proposed Draft to the
Planning Commission, and Planning Commission Recommendation to City Council) will be made available to
the public for review prior to hearings and adoption. This policy is satisfied.
Comprehensive Plan Goal 2: Land Use Planning
Policy 2.1.1: The City’s land use program shall establish a clear policy direction, comply with state and
regional requirements, and serve its citizens’ own interests.
FINDING: The proposed text amendments to the development code comply with all state and regional
requirements, as the previous findings indicate. The proposed amendments provide clarification to ambiguous,
redundant, and contradictory language in the development code. The proposed amendments also establish a
clear policy direction for the approval of housing types. This policy is satisfied.
Comprehensive Plan Goal 2: Land Use Planning
Policy 2.1.2: The City’s land use regulations, related plans, and implementing actions shall be consistent
with and implement its Comprehensive Plan.
FINDING: As demonstrated in this staff report, the proposed amendments to the Tigard Development Code
are consistent with the Tigard Comprehensive Plan. This policy is satisfied.
Policy 2.1.3: The City shall coordinate the adoption, amendment, and implementation of its land use
program with other potentially affected jurisdictions and agencies.
FINDING: Copies of the proposed text amendments were sent to affected agencies and each agency was invited
HOUSING COMPLIANCE DCA2022-00001
5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 9 OF 12
to comment on the proposal, as required by Section 18.710.110 (Type IV Procedures) and discussed in Section
V of this report. Comments submitted by affected agencies have been incorporated into this report and the
proposed amendments. This policy is satisfied.
Policy 2.1.4: The City’s land use program shall promote the efficient use of land through the creation of
incentives and redevelopment programs.
FINDING: The proposed amendments include provisions that allow for the efficient use of land. An incentive
is provided to allow smaller housing units in exchange for greater unit capacity. These changes will allow the
redevelopment of marginal properties that would not have produced increased capacity otherwise.. This policy
is satisfied.
Policy 2.1.24: The City shall establish design standards to promote quality urban development and to
enhance the community’s value, livability, and attractiveness.
FINDING: The proposed amendments further the City’s goal to provide design standards that ensure that the
value, livability, and attractiveness of the City is preserved and increased. Standards for street-facing facades
ensure that the pedestrian realm remains attractive and that housing does not present blank walls to the street.
These design standards also meet the state requirement that they be clear and objective, which prevents subjective
aesthetic criteria from being applied to residential development. The proposed standards ensure that the City’s
goals and the state requirements are simultaneously met. This policy is satisfied.
Policy 10.1.1: The City shall adopt and maintain land use policies, codes, and standards that provide
opportunities to develop a variety of housing types that meet the needs, preferences, and financial
capabilities of Tigard’s present and future residents.
FINDING: The City has expressed a desire through its Comprehensive Plan policies to provide opportunities
for greater housing variety, to meet the needs of its present and future residents at all stages of life. In addition,
the City has expressed a desire to provide greater economic integration through housing variety. The proposed
code changes further this policy directive by providing a streamlined process for development of new housing
types that are limited in size. In addition, clear and objective standards ensure that those who wish to develop
are provided with a fair, consistent, and predictable pathway to approval. These reduce the time and cost to
develop, and can help to ensure that units are sold or rented at price points that meet the needs of young families,
singles, and senior citizens. This policy is satisfied.
Policy 10.1.2: The City’s land use program shall be consistent with applicable state and federal laws.
FINDING: House Bill 2001 (2019) and Senate Bill 458 (2021) require that the City amend its development code
by June 30, 2022 to meet the provisions of Oregon Administrative Rules Chatpe 660 Division 46, and to allow
middle housing land divisions. The proposed code amendments bring the City into compliance with these
requirements. This policy is satisfied.
Policy 10.1.3: The City shall support housing affordability, special -needs housing, ownership
opportunities, and housing rehabilitation through programs administered by the state, Washington
County, nonprofit agencies, and Metro.
FINDING: The proposed code amendments support greater housing affordability and ownership opportunities
by ensuring that adequate housing variety is allowed. Affordable housing, both regulated and non-regulated,
requires flexibility in standards that make smaller housing unit production possible. First -time homeownership
HOUSING COMPLIANCE DCA2022-00001
5/2/2022 PUBLIC HEARING, STAFF REPORT TO THE PLANNING COMMISSION PAGE 10 OF 12
is dependent on the provision of smaller housing units that have a reduced up -front cost as well as lower
maintenance and utility costs. This policy is satisfied.
Policy 10.1.6: The City shall adopt and maintain land use regulations that provide opportunities to
develop housing for persons with special needs. The scale, design, intensity, and operation of these
housing types shall be compatible with other land uses and located in proximity to supporting
community services and activities
FINDING: The standards proposed for middle housing ensure compatibility with surrounding uses. In addition,
middle housing is potentially an area of housing opportunity for those with special needs, with increased
opportunity for small units, zero -step entries, group living, among other scenarios. This policy is satisfied.
Policy 10.1.8: The City shall provide opportunity for a mix and range of housing types and sizes in all
low- and medium-density residential areas, including single detached houses, accessory dwelling units,
quads, cottage clusters, courtyard units, and rowhouses.
FINDING: The proposed code amendments increase opportunities for all listed housing types in low- and
medium-density areas by streamlining approval processes and improving the clarity of development standards.
This policy is satisfied.
Policy 10.1.10: The City shall enact policies that provide for equitable housing opportunity without
discrimination or disparity based on tenure, familial status, or household composition of the occupants
of any type of housing.
FINDING: The proposed code amendments increase equitable housing opportunity through the means
described above. In addition, the development code does not treat development differentially based on housing
tenure, focusing instead on the form of buildings. Tigard has no familial requirements in relation to its definition
of a household, nor limits on occupancy based on familial status. This policy is satisfied.
Policy 10.1.11: The City shall encourage the development of mixed-income neighborhoods and ensure
opportunity for economic mobility and intergenerational wealth through affordable homeownership
programs.
FINDING: The proposed code amendments increase equitable housing opportunities and encourage mixed -
income neighborhoods by allowing a variety of housing sizes and types to co-exist in the same neighborhood.
Increased housing opportunity provides for redeuced housing costs and economic mobility. The opportunity to
purchase smaller housing units not previously available in the market will provide great er opportunity for
intergenerational wealth. This policy is satisfied.
Policy 10.2.9: The City shall require infill development to be designed to address compatibility with
existing neighborhoods.
FINDING: The proposed code amendments ensure compatibility of new housing types with existing
neighborhoods through development standar ds that reduce their size, scale, and location on lots in relation to
typical small form residential development. In addition, the standards include requirements for common open
spaces and screening at property boundaries and around off-street parking areas. This policy is satisfied.
CONCLUSION: Based on the findings above, staff concludes that the proposed code text amendment is
consistent with applicable provisions of the Tigard Comprehensive Plan.

Commentary General Notes
Text shown in strikethrough is to be removed.
Text shown in bold, italic, and underlined is to be added.
Some revisions in the code are typical throughout all chapters. Because they are typical and pervasive,
commentary for those changes is not presented each time they appear. Instead, these common changes
are summarized below:
• The phrase “single detached houses” has been replaced with “small form residential.”
• The new Type II-Modified procedure for Sublot Plats requires updating references to Land Use
Procedures throughout the Community Development Code as well as a few references in the
Tigard Municipal Code.
• As part of the zone consolidation, residential zones have been renamed to remove numbers
from their designation. These numbers often caused confusion as they were assumed to relate
to density. This disjunction was made more confusing by the addition of middle housing, where
each housing type allowed in residential zones has a different net density, none of which
corresponds to the numerical designation of the zone.
Chapter 18.20 ADMINISTRATION AND ENFORCEMENT
18.20.010 Compliance
A. Compliance. Uses, developments, and construction, reconstruction, alteration, occupation, and
use of structures must conform to the provisions of this title. Any officials, departments, or
employees of the city vested with authority to grant approvals must adhere to and require
compliance with this title, and may not grant approval for any development or use that violates or
fails to comply with this title. Any approval issued or granted in conflict with the provisions of this
title is void.
B. Obligation by successor. The regulations of this title apply to the person undertaking the
development or the use of the development and to the person’s successor in interest.
C. Most restrictive regulations apply. Where this title imposes greater restrictions than those
imposed or required by other regulations, the most restrictive or that imposing the higher standard
governs. When regulations in this title are in conflict, the most restrictive regulation governs unless
stated otherwise.
D. Required improvements. A lot area, setback, open space, or off-street parking or loading area
required by this title for a development may not be used to meet the requirements for another
development, except as specifically provided otherwise.
18.20.020 Uses and Development Allowed By Right
A. Compliance. Proposals for uses or developments that are allowed by right under this title are
subject to the procedures and regulations of this section.
B. Applicability.
1. Applicability. Uses or development allowed by right are those that do not require a land
use approval, as determined by the Director. This determination is not appealable locally
and is the final decision of the city.
2. Prohibitions.
a. Applications for uses or development that are prohibited by this title will not be
accepted.
b. The Director may refuse an application when a proposed structure has been
clearly designed for a use or development different from that which is being proposed
and could not reasonably be expected to meet the needs of the proposed use or
development.
C. Method of review. Uses and development that are allowed by right are reviewed for
compliance with the applicable standards in this title. This is a non-discretionary administrative
review. Decisions are made by the Director. The Director’s decision is not appealable locally and
is the final decision of the city.
D. Procedures.
1. Non-discretionary reviews are processed in conjunction with an application for a
development permit. Applicants for non-discretionary review must submit information
showing that the proposal complies with all applicable standards of this title.
Commentary Chapter 18.20 Administration and Enforcement
New language was added to provide greater clarity on the process of plan review for developments and
uses that do not require land use approval.
The language makes clear that the Director or designee alone determine whether a proposal requires
land use approval.
This language makes clear that plan review is a non-discretionary ministerial review of clear and
objective standards and that any decision reached is not appealable.
2. Approvals of non-discretionary reviews are based on the information submitted. If the
information is incorrect, the approval may be revoked or voided.
18.20.020 18.20.030 Land Use Applications and Development Permits
A. Land use applications. An applicant who proposes a use or development that is governed by
this title must obtain approval of all required land use applications prior to establishment or
construction. New development, changes to existing development, and changes in the type or
number of uses may require a land use approval.
B. Development permits. An applicant who proposes a use or development governed by this title
must obtain approval of all required development permits prior to establishment or construction.
New development, changes to existing development, and changes in the type or number of uses may
require a permit.

provisions relating to a land use approval or conditions of land use approval. Erection, construction,
alteration, maintenance, or use of any building or structure in violation of this title; or use, division,
or transfer of any land in violation of this title is prohibited. Each violation of a separate provision of
this title constitutes a separate infraction, and each day that a violation of this title is committed or
continued constitutes a separate infraction.
B. Responsible party. The responsible party is the person responsible for curing or remedying a
violation, which includes:
1. The owner of the property, or the owner’s manager or agent or other person in control of
the property on behalf of the owner;
2. The person occupying the property, including bailee, lessee, tenant, or other person
having possession; or
3. The person who is alleged to have committed the acts or omissions, created or allowed the

A. Vesting. Land use applications are processed based on the regulations in effect on the date an
application is submitted to the city as provided in ORS 227.178. If a land use application is
approved, development rights are vested when the land use approval is utilized as described in
Commentary Chapter 18.20 Administration and Enforcement
Subsection 18.20.040.G. Vested development rights do not expire unless new land use approvals are
obtained and utilized that supersede any preexisting vested rights.
B. Modifications. Modifications to pending land use applications that have been deemed complete
are processed based on the regulations in effect on the date the original application was submitted,
unless the modification substantially changes the proposal so as to constitute a new application, as
described in Chapter 18.710, Land Use Review Procedures.
C. Use of new regulations or mapping. Land use applications will not be accepted for
development proposals based on proposed amendments to regulations or the zoning map that have
not been adopted or have been adopted but are not yet in effect. Pre-application conferences may be
requested and held to discuss implications of proposed amendments.
D. Pre-existing approvals. Land use applications for which approvals were granted prior to the

to simplify its presentation. It also includes some policy changes that are required by state law. Quads
must now be allowed in all zones where small form residential is allowed, so they are no longer limited
to corner lots and high-designation streets in RES-A and RES-B. In addition, rowhouses must now be
allowed in all zones, although they are limited to groupings of 5 units or less, meaning that only five
units can be attached, although a rowhouse development may include more than 5 units.

Chapter 18.220 ACCESSORY DWELLING UNITS
18.220.010 Purpose
The purpose of this chapter is to provide clear and objective standards for the establishment of detached
accessory dwelling units on lots with small form residential development. Attached accessory dwelling
units are considered small form residential development for the purposes of meeting the requirements
of applicable state law and administrative rules. single detached houses to achieve the following:
Detached accessory dwelling units have the following characteristics:
A. They are of limited size and height;
B. They are located in a manner that is subordinate to the primary residential use;
C. They may be newly constructed or converted from existing dwelling spaces or accessory
structures;
D. They may share utilities with a primary dwelling unit where allowed by the applica ble
service provider, and
E. The units require no additional off-street parking.
A. Increase the number of affordable dwelling units;
B. Accommodate incremental growth in neighborhoods while preserving residential quality of
life;
C. Provide for a variety of housing types that meet the needs of Tigard’s diverse population at all
stages of life; and
D. Encourage housing that allows residents to remain in their communities and neighborhoods as
their needs change.
18.220.020 Applicability
A. Applicability. The approval process and standards of this chapter apply to attached and
detached accessory dwelling units and modifications to attached and detached accessory dwelling
units wherever this housing type is allowed, as provided in the use and housing type tables in

Section 18.710.050. Accessory dwelling units must comply with the clear and objective standards of
Section 18.220.040 and all other applicable standards of this title.
Commentary Chapter 18.220 Accessory Dwelling Units
The purpose statement is updated to focus more on the characteristics of accessory dwelling unit
development. This better explains the standards provided and helps with proposals for adjustments to
standards.
This chapter now applies only to detached accessory dwelling units, and a reference is provided to point
to standards for attached accessory dwelling units in the small form residential chapter.
Clarifying language.
Changing accessory dwelling unit approval from a Type I land use process to development allowed by
right. Many housing types are now required to be allowed through plan check only, including small form
residential, and so it does not make sense to provide a higher level of review for detached ADUs.
18.220.040 Approval Criteria
The approval authority will approve or approve with conditions an accessory dwelling unit application
when all of the standards in Section 18.220.050 are met.
18.220.040050 Standards
A. Unit Count Number of dwelling units.
1. A maximum of 2 accessory dwelling units are allowed per single detached house.

2. A structure containing an attached accessory dwelling unit may not exceed the maximum
height for a single detached house in the base zone.
D. Setbacks. Detached aAccessory dwelling units must meet the setback standards for a single
detached house small form residential development in the applicable base zone, with the following
exceptions: that a detached accessory dwelling unit may be located within 5 feet of the rear property
line if the accessory dwelling unit is 15 feet or less in height.
1. Detached accessory dwelling units must be located no closer to a front property line

meet the same standards for windows and street-facing facades that apply to small form
residential development in the applicable base zone, as provided in Chapter 18.290, Small Form
Residential.
G. Home occupations. Type II Home Occupations are prohibited on a lot with two accessory
dwelling units.
Commentary Chapter 18.220 Accessory Dwelling Units
This language is updated to make clear that a detached ADU is allowed only on a lot that has one or two
units on it. If there are already three units in a small form residential development, then a detached
ADU is prohibited. Only one detached ADU may be development per lot.
Removing the standards for attached ADUS.
Providing clarifying language and adding a requirement that detached ADUs must be placed behind the
facade of the primary small form residential, meaning that detached ADUs cannot be buil t in a front
yard.
Removing the entrance standard and instead referring out to the standards for windows and street-
facing facades that apply to small form residential. The lack of street-facing facade standards for ADUs
caused some issues with units not meeting the intent of the standards for the primary unit.
GH. Accessory dwelling units in accessory structures additions and conversions. Detached
aAccessory dwelling units may be added to or created from existing accessory structures such as
detached garages. The maximum square footage requirements for the accessory dwelling unit
apply to the entire structure, including any portion that remains in use as an accessory structure.,
subject to the maximum square footage and height restrictions for each, as measured using the
method provided in Section 18.40.130.
Commentary Chapter 18.220 Accessory Dwelling Units
The allowance for ADUs over existing detached garages caused many issues, both in its
understandability and in its application. In cases, an applicant could build a garage, and then after final
inspection add and ADU, which allowed for an oversized unit. This was not the intent of the code and so
this provision has been removed.

Chapter 18.240 COTTAGE CLUSTERS
18.240.010 Purpose
The purpose of this chapter is to provide clear and objective standards for cottage cluster development
to meet the requirements of state law and Oregon Statewide Planning Goal 10 . Optional alternative
standards are also provided for cottage cluster development. Cottage cluster development has the
following characteristics:
A. The development consists of detached cottages of limited size and footprint;
B. The cottages are arranged around a courtyard that provides shared open space;
C. The courtyard opens to the street and provides a visual and physical connection to the
interior of the development;
D. Internal pathways connect the cottages to the shared site elements and to the adjacent
sidewalk;
E. Off-street parking areas are efficiently designed and screened; and
F. The overall design emphasizes sustainable development patterns and climate resiliency.
Cottage clusters are groups of four to twelve detached dwelling units that are of smaller size than the
typical single detached house. The purpose of this chapter is to provide standards that promote quality
development and enhance the livability, walkability, and safety of the community. Cottage cluster
development is intended to achieve the following:
A. Increase the number of affordable dwelling units;
B. Accommodate incremental growth in neighborhoods while preserving residential quality of
life;
C. Provide for a variety of housing types that meet the needs of Tigard’s diverse population at all
stages of life;
D. Encourage housing that allows residents to remain in their communities and neighborhoods as
their needs change; and
E. Facilitate more efficient use of land through smaller dwelling units.
18.240.020 Applicability
The standards of this chapter apply to cottage cluster development wherever this housing type is allowed
as provided in the use and housing type tables in Chapter 18.110, Residential Zones and Chapter 18.120,
Commercial Zones. Additional standards apply in the River Terrace Plan District, as provided in
Chapter 18.640, River Terrace Plan District.
18.240.030 Application Type Review Process
Cottage cluster development requires a site development review application. Cottage cluster
development requires review through one of the following:
A. A cottage cluster development that complies with the clear and objective standards of Section
18.240.050 requires development permits.
Commentary Chapter 18.240 Cottage Clusters
The purpose statement is updated to focus more on the characteristics of cottage cluster development.
This better explains the standards provided and helps with proposals for adjustments to standards.
The city is required under state law to allow cottage cluster development with the same level of review
that is applied to small form residential. The approval process has been updated to meet this
requirement, with only clear and objective standards, but to also provide an alternative Type II land use
approval that allows for more flexibility and eligibility for adjustments.
B. A cottage cluster development that does not comply the clear and objective standards of
Section 18.240.050 requires a site development review application, as provided in Section
18.780.040, subject to the alternative standards of Section 18.240.060 and any other applicable
standards in this title.
18.240.040 General Provisions
Adjustments to the clear and objective standards of Section 18.240.050 are prohibited.
All lots approved for cottage cluster development through the provisions of this chapter will be
conditioned to record a deed restriction prohibiting any type of development other than cottage cluster
development on the lot. This deed restriction cannot be removed except through a land division or lot line
adjustment process that brings the lot into conformance with the standards for development of other
housing types. A cottage cluster deed restriction imposed as a condition of a previous or concurrent land
division or lot line adjustment process meets this standard.
18.240.050 Clear and Objective Development Standards
A. Unit Count Density. The required number of cottages in a density of a cottage cluster
development is determined as follows according to the following:
1. A cottage cluster development must contain a minimum of 4 cottagesdwelling units and a
maximum of 12 dwelling units; and
2. One A minimum of one cottage dwelling unit is required for every 2,500 square feet of
gross lot area. Any designated sensitive lands on the lot are included in the lot area. Any
required dedications for public improvements are not excluded from included in the lot area.
B. Minimum lot width. The minimum lot width is 75 feet.
1. The minimum lot width in the RES-A zone is 65 feet.
2. The minimum lot width in the RES-B zone is 50 feet.
3. The minimum lot width in all other zones is 0 feet.
C. Setbacks. Setbacks apply only to the perimeter of the cottage cluster development.
1. The minimum setback of cottages from all street property lines is 10 feet.
2. The minimum setback of cottages from all other perimeter property lines is 5 feet.
D. Common courtyard. A single common courtyard must be provided. This common courtyard is
not required to be rectangular; however, a single rectangle meeting size and location standards
must be entirely contained within the common courtyard as shown in Figure 18.240.1. The
common courtyard must be sized and located to contain a rectangle The rectangle is a portion of
the common courtyard used to demonstrate compliance with all of the standards listed below. that
meets the following:
1. The minimum size of the rectangle is 15 percent of the gross lot area;.
2. The rectangle must abut a minimum of 15 percent of the length of a single street property
line;. See Figure 18.240.2.
3. The rectangle area must may not abut more than 40 percent of the length of a single
street property line;. and
Commentary Chapter 18.240 Cottage Clusters
The plan check approval standards cannot be adjusted. Only the alternative standards are eligible for
adjustment.
State law requires that the maximum unit count be removed.
The minimum lot width for this pathway is lowered, as it has to be the same standard as is applied to
small form residential in the same zone.
The common courtyard rectangle is the means by which the city reviews courtyards using only clear and
objective standards. However, it has caused some confusion. The language changes here are intended to
better describe the rectangle, its purpose, and how it is reviewed.
4. The rectangle must be a minimum of 15 feet wide along its entire length.
5. Each cottage must have all points along one facade located entirely within 10 feet of
the rectangle. See Figure 18.240.3.

(UFM). All required trees must be a minimum caliper of 1.5 inches at the time of planting
and meet the standards in Section 13 Part 2 and Appendix 3 of the UFM for soil volume and
species. Trees planted to meet this standard are development trees. The applicant must pay
the tree inventory fee listed in the city’s Master Fees and Charges Schedule.
3. The minimum number of required street trees is determined by dividing the length in
feet of the site’s street frontage by 40 feet. When the result is a fraction, the minimum
number of street trees is the nearest whole number. More than the minimum number of
street trees may be required along the site’s frontage depending upon the stature of trees
chosen and the specific spacing standards for the chosen trees.
a. Street trees must be planted within the right-of-way wherever practicable. Street
trees may be planted a maximum of 6 feet from the right-of-way in an easement when
planting within the right-of-way is not practicable as determined by the City Engineer.
b. An existing tree may be used to meet the street tree standards provided that:
i. The largest percentage of the tree trunk immediately above the trunk flare or
root buttresses is either within the subject site or within the right -of-way
immediately adjacent to the subject site; and
ii. The tree would be permitted as a street tree in compliance with Urban
Forestry Manual street tree planting and soil volume standards if it were newly
planted.
I. Fencing.
1. Fences located within 3 feet of a side or rear lot line are subject to the height
requirements of Section 18.210.020, except that fences within a front setback must not
exceed 3 feet in height even when the lot abuts a collector or arterial street.
2. Fences located anywhere other than within 3 feet of a side or rear lot line must not

frame.
18.240.090 Pre-existing Structures
Any single pre-existing primary dwelling unit or detached accessory dwelling unit on the same lot with
a proposed cottage cluster development may be included in the cottage cluster subject to the following:
A. The primary dwelling unit must have received a final inspection a minimum of 5 years prior
to the date of the cottage cluster application for development permits.
B. Any detached accessory dwelling unit must have been constructed and received a final
inspection a minimum of 1 year prior to the date of the cottage cluster application for

the purposes of meeting the required minimum number of cottages.
2. Any primary or accessory dwelling unit proposed to remain under these provisions must
not be modified in a manner that causes them to go further out of conformance with the
standards of this chapter.
3. The floor area of any primary or accessory dwelling unit proposed to remain is not
included in the maximum average floor area calculation for the cottage cluster development.
4. Any primary or accessory dwelling unit proposed to remain is not required to meet
standards for location or a common courtyard-facing main entrance.
18.240.100 Accessory Structures
Accessory structures are allowed subject to the following:
A. The total maximum floor area of all accessory structures on a lot is 528 square feet. The
floor area of parking structures does not count toward this maximum. Cottage cluster
Commentary Chapter 18.240 Cottage Clusters
The height standard of 25 feet was restored in the alternative pathway. This is intended to ensure better
design of small units.
A lower window requirement is allowed here because there is some discretion in determining what is a
street-facing facade in this type of development.
State law requires that existing structures may be included in a cottage cluster development. These
standards are the minimum to meet state law.
The accessory structure standards are moved from elsewhere.
developments with more than 12 cottages on a lot may include one additional accessory structure
of 528 square feet.
B. The maximum height of accessory structures is 15 feet.
C. Accessory structures are prohibited within the front setback.
D. Accessory structures may be located within a required side or rear setback provided they are
located a minimum of 5 feet from the side and rear property lines.
Commentary Chapter 18.240 Cottage Clusters
Chapter 18.250 COURTYARD UNITS
18.250.010 Purpose
The purpose of this chapter is to provide clear and objective standards for courtyard unit development.
Optional alternative standards are also provided for courtyard unit development. Courtyard unit
development has the following characteristics:
A. The development consists of attached dwelling units of limited size and height;
B. The buildings containing the dwelling units are arranged around a courtyard that provides
shared open space among the units;
C. The courtyard opens to the street and provides a visual and physical connection to the
interior of the development and the entrance-bearing facades of the dwelling units;
D. Internal pathways connect the units to the shared site elements and to the adjacent sidewalk;
and
E. Off-street parking areas are efficiently designed and screened; and
F. The overall design emphasizes sustainable development patterns and climate resiliency.
Courtyard units are groups of five to twelve attached dwelling units that are of smaller size and scale than
other attached housing types such as apartments and rowhouses. The purpose of this chapter is to provide
standards that promote quality development and enhance the livability, walkability, and safety of the
community. Courtyard unit development is intended to achieve the following:
A. Increase the number of affordable dwelling units;
B. Accommodate incremental growth in neighborhoods while preserving residential quality of
life;
C. Provide for a variety of housing types that meet the needs of Tigard’s diverse population at all
stages of life;
D. Encourage housing that allows residents to remain in their communities and neighborhoods as
their needs change; and
E. Facilitate more efficient use of land through smaller dwelling units.
18.250.020 Applicability
The standards of this chapter apply to courtyard unit development wherever this housing type is allowed
as provided in the use and housing type tables in Chapter 18.110, Residential Zones and Chapter 18.120,
Commercial Zones. Additional standards apply in the River Terrace Plan District, as provided in
Chapter 18.640, River Terrace Plan District.
18.250.030 Application Type Review Process
Courtyard unit development requires a site development review application. Courtyard unit
developments require review through one of the following:
A. A courtyard unit development that complies with all of the clear and objective standards of
Section 18.250.050 requires development permits.
Commentary Chapter 18.250 Courtyard Units
The purpose statement is updated to focus more on the characteristics of courtyard unit development.
This better explains the standards provided and helps with proposals for adjustments to standards.
The city is not required under state law to allow courtyard unit development with the same level of
review that is applied to small form residential. However, because of this housing type’s similarity to
cottage cluster development, it makes sense to provide a consistent approach. The approval process has
been updated to provide a dual pathway approval approach, with clear and objective standards and
also an alternative Type II land use approval that allows for more flexibility and eligibility for
adjustments.
B. A courtyard unit development that does not comply with all of the clear and objective
standards of Section 18.250.050 requires a site development review application, as provided in
Paragraph 18.780.040, subject to the alternative standards of Section 18.240.060 and any other
applicable standards in this title.
18.250.040 General Provisions
Adjustments to the clear and objective standards of 18.250.050 are prohibited.
All lots approved for courtyard unit development through the provisions of this chapter will be
conditioned to record a deed restriction prohibiting any type of development other than courtyard unit
development on the lot. This deed restriction cannot be removed except through a land division or lot line
adjustment process that brings the lot into conformance with the standards for development of other
housing types. A courtyard unit development deed restriction imposed as a condition of a previous or
concurrent land division or lot line adjustment process meets this standard.
18.250.050 Clear and Objective Development Standards
A. Unit Count Density. The required number of dwelling units in density of a courtyard unit
development is determined as follows according to the following:
1. A courtyard unit development must contain a minimum of 5 dwelling units and a
maximum of 12 dwelling units.

area. Any designated sensitive lands on the lot are included in the gross lot area. Any required
dedications for public improvements or public access are not included in the lot area.
B. Minimum lot width. The minimum lot width is 75 feet.
C. Setbacks. Setbacks apply only to the perimeter of the courtyard unit development.
1. The minimum front and side setbacks are 10 feet.
2. The minimum rear setback is 15 feet.
3. The maximum setback from a front any street property line is 20 feet.
D. Common courtyard. A single common courtyard must be provided. This common courtyard is
not required to be rectangular; however, a single rectangle meeting size and location standards
must be entirely contained within the common courtyard as shown in Figure 18.250.1. The
common courtyard must be sized and located to contain a rectangle The rectangle is a portion of
the common courtyard used to demonstrate compliance with all of the standards listed below. that
meets the following:
1. The minimum size of the rectangle is 15 percent of the gross lot area;
2. The rectangle must abut a minimum of 15 percent of the length of a single street property
line;
3. The rectangle area may must not abut more than 40 percent of the length of a single
street property line; and
4. The rectangle must be a minimum of 15 feet wide along its entire length.
Commentary Chapter 18.250 Courtyard Units
The plan check approval standards cannot be adjusted. Only the alternative standards are eligible for
adjustment.
The common courtyard rectangle is the means by which the city reviews courtyards using only clear and
objective standards. However, it has caused some confusion. The language changes here are intended to
better describe the rectangle, its purpose, and how it is reviewed.
5. Each building must have all points along the courtyard-facing facade located entirely
within 10 feet of the rectangle.
46. Dwelling units and parking and maneuvering areas are prohibited within the rectangle.

(UFM). All required trees must be a minimum caliper of 1.5 inches at the time of planting
and meet the standards in Section 13 Part 2 and Appendix 3 of the UFM for soil volume and
species. Trees planted to meet this standard are development trees. The applicant must pay
the tree inventory fee listed in the city’s Master Fees and Charges Schedule.
3. The minimum number of required street trees is determined by dividing the length in
feet of the site’s street frontage by 40 feet. When the result is a fraction, the minimum
number of street trees is the nearest whole number. More than the minimum number of
street trees may be required along the site’s frontage depending upon the stature of trees
chosen and the specific spacing standards for the chosen trees.
a. Street trees must be planted within the right-of-way wherever practicable. Street
trees may be planted a maximum of 6 feet from the right-of-way in an easement when
planting within the right-of-way is not practicable as determined by the City Engineer.
b. An existing tree may be used to meet the street tree standards provided that:

Chapter 18.270 QUADS
18.270.010 Purpose
The purpose of this chapter is to provide clear and objective and alternative standards for quad
development to meet the requirements of state law and Oregon Statewide Planning Goal 10. Optional
alternative standards are also provided for quad development. Quad development has the following
characteristics:
A. The development is made up of four attached dwelling units of limited size;
B. The configuration of the units provides visual access to the street for all dwelling units;
C. The form of the building resembles a two-story single detached house in size and
appearance;
D. Off-street parking areas are efficiently designed and screened; and
E. The overall design emphasizes sustainable development patterns and climate resiliency.
Quads are a type of attached housing with two dwelling units side-by-side on the first story and two
dwelling units side-by-side on the second story. The dwelling units are of smaller size than the typical
apartment or single detached house. The purpose of this chapter is to provide standards that promote
quality development and enhance the livability, walkability, and safety of the community. Quad
development is intended to achieve the following:
A. Increase the number of affordable dwelling units;
B. Accommodate incremental growth in neighborhoods while preserving residential quality of
life;
C. Provide for a variety of housing types that meet the needs of Tigard’s diverse population at all
stages of life;
D. Allow development of attached housing that is similar in size and form to single detached
houses;
E. Encourage housing that allows residents to remain in their communities and neighborhoods as
their needs change; and
F. Facilitate more efficient use of land through smaller dwelling units.
18.270.020 Applicability
The standards of this chapter apply to quad development wherever this housing type is allowed as
provided in the use and housing type tables in Chapter 18.110, Residential Zones and Chapter 18.120,
Commercial Zones. Additional standards apply in the River Terrace Plan District, as provided in
Chapter 18.640, River Terrace Plan District.
18.270.030 Application Type Compliance
Quad development must comply with the clear and objective standards of Section 18.270.040 and all
other applicable standards of this title. Quad development requires a site development review
application.

Director may waive the requirement for a pre-application conference. Legislative actions are exempt
from a pre-application conference.
1. To request a pre-application conference, a prospective applicant must submit a pre-
application request form, a brief description of the proposed uses, and a site plan.
2. When a pre-application conference is required, the prospective applicant must meet with
the city for the purpose of identifying policies and regulations that relate to the proposed
development, providing technical data and assistance that will aid the applicant, and
identifying other opportunities or constraints that relate to the proposed development.
3. Failure of the Director to provide any of the information required by this chapter does not
constitute a waiver of the standards, criteria, or requirements of the applications.
Commentary Chapter 18.710 Land Use Procedures
A new review type has been added for Sublot Plats.
4. Due to possible changes in applicable law, the facts and circumstances of the property,
and the information developed during the review process and other factors, information
provided by the city during the pre-application conference is not binding. Applicants are solely
responsible for demonstrating compliance with all applicable standards.
5. The prospective applicant has one year from the date of the pre-application conference to
submit a land use application for the proposed development.
B. Neighborhood meetings. A prospective applicant must hold a neighborhood meeting prior to
filing the following applications: comprehensive plan map amendment (quasi-judicial), conditional
use, major modifications, planned development review, sensitive lands review (Type II and III), site
development review (Type II), subdivision, and zoning map amendment (quasi-judicial).

city with the application.
C. Application submittal.
1. Applications may be initiated by:
a. All of the property owners, contract purchasers of the subject property, or any agent
authorized to represent the property owners or contract purchasers. Easement holders are
not considered owners for this section. If the subject property was divided without a

Commentary Chapter 18.710 Land Use Procedures
l. Copy of the mailed neighborhood meeting letter, the mailing list, affidavits of mailing
and posting, copy of the meeting sign-in sheets, meeting minutes, and any handouts
provided at the meeting, including the site plan, if applicable.
D. Application completeness.
1. When the application is accepted, the Director will review the application for
completeness. If the application is incomplete, the Director will notify the applicant of exactly
what information is missing within 30 days of receipt of the application and allow the
applicant to submit the missing information.
2. The application will be deemed complete upon the receipt of:
a. All of the missing information;
b. Some of the missing information and a written notice from the applicant that no
other information will be provided; or
c. Written notice from the applicant that none of the missing information will be
provided.
3. If the applicant does not submit the missing information or provide written notice that no
additional information will be provided, the application will be deemed void on the 181st day
after submittal.
E. Modifications of applications. A modification of application means the applicant’s submittal of
new information after an application has been deemed complete and prior to close of the record on a
pending application that would modify a development proposal by changing one or more of the
following components: proposed uses, operating characteristics, intensity, scale, or site layout, in a
manner that requires the application of new criteria to the proposal or that would require a
substantial change to the findings of fact. It does not mean a submittal of new evidence that merely
clarifies or supports the pending application.
1. A Type I or Type II application may be modified up until the decision is issued. A Type II
application that is appealed or Type III application may be modified up until the close of the
record.
2. The approval authority will not consider any evidence submitted by the applicant that
would constitute a modification of an application, as defined above, unless a new application is
submitted for the modification. The modification constitutes a new application and restarts the
120-day clock for the application being modified.
3. Prior to the first public hearing or if a hearing is not required, the Director will have sole
authority to determine whether an applicant’s submittal constitutes a modification. After such a
time, the hearing authority will make such determination. The determination on whether a
submittal constitutes a modification is appealable only to the Land Use Board of Appeals and
only after a final decision on the application is issued.
F. Amended decision process.
1. The purpose of an amended decision is to provide the Director the ability to correct
typographical errors, rectify inadvertent omissions, or make other minor changes that do not
materially alter the decision.
2. The approval authority may issue an amended decision after the notice of final decision
has been issued but before the appeal period has expired.
Commentary Chapter 18.710 Land Use Procedures
3. The notice of an amended decision is the same as that which applies to a Type II
procedure, as provided in Section 18.710.060.
G. Withdrawal of an application. An application may be withdrawn prior to issuance of a decision.
H. Re-submittal of application following denial. Applications that have been denied, excluding
applications denied solely on procedural grounds, may not be resubmitted for the same or a
substantially similar proposal unless one or more of the following are met:
1. Twelve months has passed since the denial became final;
2. Substantial changes are made to the application that resolve all findings for denial of the
application; or
3. Standards and criteria relative to the findings of the original denial have changed.
I. Receipt of submittals. Any submittals for which a deadline is provided for in this chapter must
be addressed to the recipient department designated in the notice and actually and physically
received by the designated recipient department on or before the close of business on the due date,
except that if the due date falls on a state or federal holiday, a regular weekday that the Community
Development Department, or its successor, is not open for business, or a weekend, will be extended
to the close of business on the next day that the department is open for business. Emails are
considered received at the time shown on the city’s email system. Submittals received after the
deadline will not be considered or effective.
J. Conformance with application. Unless provided otherwise in the decision, development must
conform in all material respects to the approved application and submittals in support of the
application.
18.710.040 Types of Reviews
A. General. This section defines the review types and establishes the approval and appeal authority
for each.
B. Review types defined. There are four review procedure types: Type I, Type II, Type III, and
Legislative. Table 18.710.1 contains the city’s land use application types and associated review
types. The review types are defined as follows:
1. Type I procedures apply to land use applications that are governed by clear and objective
approval criteria or development standards that may require the exercise of professional
judgment about technical issues only. Type I actions are decided by the Director without
public notice and without a public hearing.
2. Type II procedures apply to land use applications that are governed by subjective approval
criteria or development standards that may require the exercise of limited discretion. Type II
actions are decided by the Director with public notice. If any party with standing appeals a Type
II decision, the appeal of such decision will be heard by the Hearings Officer.
3. Type III procedures apply to land use applications that are governed by approval criteria
that require the exercise of discretion and judgment and about which there may be broad public
interest. Type III applications are decided by the Hearings Officer (Type III-HO)
or the Planning Commission (Type III-PC) with appeals to the City Council. Type III-Modified
are decided by the City Council with a recommendation from the Planning Commission.
Commentary Chapter 18.710 Land Use Procedures
4. Legislative actions involve the establishment and modification of land use plans, policies,
and regulations. The Legislative procedure includes two public hearings; the first by the
Planning Commission and then by the City Council. The hearings provide opportunities for
public comment and input on actions that may affect large areas of the city.
C. Approval and appeal authorities. The approval and appeal authorities for each review type are
provided in Table 18.710.2. The decision of the appeal authority is the city’s final decision. Parties
with standing may appeal the city’s final decision to the Oregon Land Use Board of Appeals.

D. Determination. The Director will determine the most appropriate review type for land use
applications or actions requested. The Director determination is the final local decision and will
favor the review type that provides the most appropriate public notice and opportunity for public
comment.
E. Notice.
1. A failure of any person to receive actual notice that was mailed does not invalidate the
decision or action. In all other cases, failure to receive notice or irregularities in providing
notice is grounds for invalidation only if the party demonstrates substantial prejudice. The city
may require re-notification, grant a continuance, or take other actions to avoid prejudice
without requiring that a new application be filed.
2. The city may provide notice in excess of the minimum requirement.
3. Public notices required by this section will be sent to the names and addresses of owners

chapter invalidates an action only if the person alleging the error demonstrates that the error
occurred and that person’s substantial rights have been prejudiced.

was mailed.
3. An appeal must include:
a. The date and case file number of the decision being appealed;
b. Documentation that the person filing the appeal has standing to appeal;
c. A detailed statement describing the basis of appeal; and
d. Payment of the required fee, based on the fee schedule in effect at time of submittal, as
adopted by City Council. The fee is established by the Director. The maximum fee for an

18.710.110100 Quasi-Judicial Hearings
A. Procedures. The following procedures apply to all quasi-judicial hearings:
Commentary Chapter 18.710 Land Use Procedures
1. At the commencement of the hearing, a statement will be made to those in attendance
that:
a. Lists the applicable substantive criteria;
b. States that testimony and evidence must be directed toward the relevant approval
criteria described in the staff report, or other criteria in the plan or land use regulation that
the person testifying believes to apply to the decision; and
c. States that failure to raise an issue with sufficient specificity to afford the approval
authority and the parties an opportunity to respond to the issue, precludes an appeal to the
Land Use Board of Appeals on that issue and that failure of the applicant to object to a
condition of approval may preclude an action for damages in circuit court.
2. Parties to a quasi-judicial hearing are entitled to an impartial hearing authority as free
from potential conflicts of interest and pre-hearing ex parte contacts as reasonably possible. It
is recognized, however, that the public has a countervailing right of free access to public
officials; therefore:
a. Hearing authority members must disclose the substance of any pre-hearing ex parte
contacts with regard to the matter at the commencement of the public hearing on the
matter. The member must state whether the contact has impaired the impartiality or
ability of the member to vote on the matter and provide the parties the right to rebut the
substance of the communication. The member will participate or abstain accordingly.
b. Any member of the hearing authority may not participate in any proceeding or
action in which any of the following has a direct or substantial financial interest: the
member or member’s spouse, brother, sister, child, parent, father-in-law, mother-in-law,
or partner; any business in which the member is then serving or has served within the
previous 2 years; or any business with which the member is negotiating for or has an
arrangement or understanding concerning prospective partnership or employment. Any
actual or potential interest must be disclosed at the meeting of the hearing authority
where the action is being taken.
c. Disqualification of a hearing authority member due to contacts or conflict may be
ordered by a majority of the members present and voting. The person who is the subject
of the motion may not vote.
d. If all members abstain or are disqualified, the administrative rule of necessity will
apply. All members present who declare their reasons for abstention or disqualification
will thereby be re-qualified to act.
e. In cases involving the disqualification or recusal of a Hearings Officer, the city will
provide a substitute Hearings Officer in a timely manner subject to the above impartiality
rules.
3. Prior to the conclusion of the initial evidentiary hearing, any participant may request an
opportunity to present additional relevant evidence or testimony. The local hearing authority
may grant such request by continuing the public hearing in compliance with Subparagraph
18.710.110100.A.4.a or by leaving the record open for additional written evidence or
testimony as provided in Subparagraph 18.710.110100.A.4.b.
4. If the hearing authority grants a continuance, the hearing will be continued to a date, time,
and place certain at least 7 days from the date of the initial evidentiary hearing. An opportunity
Commentary Chapter 18.710 Land Use Procedures
will be provided at the continued hearing for persons to present and rebut new evidence and
testimony. If new written evidence is submitted at the continued hearing, any person may
request, prior to the conclusion of the continued hearing, that the record be left open for at least
7 days, to submit additional written evidence or testimony for the purpose of responding to the
new written evidence.
5. If the hearing authority leaves the record open for additional written evidence or
testimony, the record must be left open for at least 7 days. Any participant may file a written
request with the city for an opportunity to respond to new evidence submitted during the
period the record was left open. If such a request is filed, the hearing authority must reopen the
record in compliance with Paragraph 18.710.110100.A.5.
a. A continuance or extension granted is subject to the limitations of ORS 227.178,
unless the continuance or extension is requested or agreed to by the applicant;
b. Unless waived by the applicant, the city will allow the applicant at least 7 days after
the record is closed to all other parties to submit final written arguments in support of the
application period. The applicant’s final submittal will be considered part of the record
but may not include any new evidence.
B. The record.
1. The record contains all testimony and evidence that is submitted and not rejected.
2. The hearing authority may take official notice of judicially cognizable facts in compliance
with the applicable law. If the hearing authority takes official notice, it must announce its
intention and allow the parties to the hearing to present evidence concerning the fact.
3. The hearing authority must retain custody of the record as appropriate, until a final
decision is rendered.
4. When a hearing authority re-opens a record to admit new evidence, arguments, or
testimony, any person may raise new issues that relate to the new evidence, arguments, or
testimony, or criteria that apply to the matter at issue.
C. Ex parte communications.
1. Members of the hearing authority may not:
a. Communicate, directly or indirectly, with any party or representative of a party in
connection with any issue involved in a hearing, except upon giving notice, and an
opportunity for all parties to rebut the substance of the communication; or
b. Take notice of any communication, report, or other materials outside the record
prepared by the proponents or opponents in connection with the particular case unless the
parties are afforded an opportunity to contest the materials so noticed.
2. No decision or action of the hearing authority will be invalid due to ex parte contacts or
bias resulting from ex parte contacts with a member of the approval authority if the member of
the approval authority receiving contact:
a. Places on the record the substance of any written or oral ex parte communications
concerning the decision or action; and
b. Makes a public announcement of the content of the communication and of the
parties’ right to rebut the substance of the communication made at the first hearing
Commentary Chapter 18.710 Land Use Procedures
following the communication where action will be considered or taken on the subject to
which the communication is related.
3. Members of the hearing authority are subject to the provisions of ORS 244 and the
provisions of this section.
4. A communication between city staff and the hearing authority is not considered an ex
parte contact.
D. . Presenting and receiving evidence.
1. The hearing authority may set reasonable time limits for oral presentations and may limit
or exclude cumulative, repetitious, irrelevant, or personally derogatory testimony.
2. Oral testimony will not be accepted after the close of the public hearing. Written
testimony may be received after the close of the public hearing, but only in compliance with
the schedule and procedure announced by the hearing authority prior to the close of the public
hearing, or as otherwise provided by this section.
18.710.120110 Legislative Procedure

Commentary Chapter 18.830 Subdivisions
Chapter 18.840 SUBLOT PLATS
18.840.010 Purpose
The purpose of this chapter is to:
A. Provide local rules, regulations, and standards for dividing a lot into sublots and tracts to meet
the requirements of state law for middle housing land divisions;
B. Provide a legal distinction between the primary lot and the sublots and tracts created by a
sublot plat;
C. Ensure adequate public facilities, including infrastructure for transportation, water supply,
sanitary sewer, and stormwater; and
E. Require adequate documentation of the ownership of shared lot elements and the associated
responsibility for their maintenance.
18.840.020 Applicability
A. Applicability. The provisions of this chapter apply to the platting of sublots and tracts on a lot
containing or proposed to contain one of the following types of development:
1. Cottage Clusters,
2. Courtyard Units,
3. Rowhouses,
4. Small Form Residential, or
5. Accessory Dwelling Units.
B. Prohibitions. Stacked dwelling units are prohibited from being divided using the provisions of
this chapter.
18.840.0 30 General Provisions
A. Conformance with state statute. All sublot plat proposals must comply with all state
regulations.
B. Resultant land units. The units of land created by a sublot plat are either sublots or tracts and
are collectively considered to be a single lot for all but platting and property transfer purposes. All
of the provisions of this title continue to apply to the lot and existing or future development on the
lot, including but not limited to, the following:
1. Lot standards such as size, setbacks, lot coverage, and lot width and depth;
2. Designation of housing types on the lot; and
3. Allowed number of dwelling units.
C. Special flood hazard area dedications. Where land filling or development is allowed within and
adjacent to the special flood hazard area outside the zero-foot rise floodway, the city will require the
dedication of sufficient open land area for a greenway adjacent to and within the special flood
hazard area. This area will include portions at a suitable elevation for the construction of a path,
sidewalk, or trail within the special flood hazard area as provided in the adopted trails plan or
transportation plan.
Commentary Chapter 18.840 Sublot Plats
This is a new chapter intended to implement the requirements of Senate Bill 458, allowing division of
middle housing developments into smaller lots for the purpose of fee-simple property transfer.
The process outlined in this chapter can only be used to divide certain types of development.
An important distinction between a sublot and a lot is that a sublot only has legal status for the purpose
of property transfer. They cannot create new lots for development. Collectively, the sublots are still
considered part of the parent lot for the purposes of meeting development standards.
D. Need for adequate utilities. All sublot plat proposals must provide adequate public utilities and
facilities such as sanitary sewer, stormwater, gas, electrical, and water systems to each unit, subject
to the standards of each utility provider, and the provisions of Sections 18.910.150 and 18.910.170.
E. Need for adequate drainage. All sublot plat proposals must have adequate drainage provided to
reduce exposure to flood damage.
F. Determination of base flood elevation. Where base flood elevation has not been provided or is
not available from another authoritative source, it must be generated for sublot plat proposals and
other proposed developments that contain at least 50 lots or 5 acres (whichever is less).
G. Adjustments. Adjustments to sublot plat regulations must be made in compliance with
Chapter 18.715, Adjustments. Any adjustment request must be processed concurrently with the
sublot plat proposal.
H. Prohibition on sale of lots. Sale of sublots created through the sublot plat process is prohibited
until the final plat is recorded.
I. Prohibition on further division. Further division of sublots is prohibited.
18.840.0 40 Approval Process
A. Approval through two-step process. A sublot plat application is processed through a two-step
process: the preliminary sublot plat and the final sublot plat.
1. Preliminary sublot plat. A preliminary plat application is processed through a Type II-
Modified procedure, as provided in Section 18.710.070. An application for a preliminary
sublot plat may be submitted:
a. Concurrently with development permits or applications for site development review
or planned development review; or
b. At any time after a middle housing development has passed final building inspection
or received permanent certificates of occupancy for all units proposed to be included in
the sublot plat.
2. Final sublot plat. A final sublot plat may only be submitted after the preliminary sublot
plat has been approved, and after all development permits have been issued and foundation
inspections have been approved for all units proposed to be included in the sublot plat. The
final sublot plat must satisfy all conditions of approval from the preliminary sublot plat
approval.
B. Approval period. Expirations and extensions of approvals are provided in Subsection
18.20.040.G.
18.840.0 50 Approval Criteria—Preliminary Sublot Plat
The approval authority will approve or approve with conditions an application for a preliminary sublot
plat when all of the following are met:
A. The proposed sublots and tracts must comply with the following standards:
1. Each sublot must contain only one dwelling unit.
Commentary Chapter 18.840 Sublot Plats
Sublot plats use a standard two-step process like other land divisions.
Sublot plats can be processed concurrently with a proposed development or after it is completed. A
sublot plat cannot be processed on a lot that does not have a permitted middle housing development.
There are only a few criteria for the approval of a sublot plat, and they are all related to the provision in
state law that specifies that the development must continue to comply with the middle housing code. As
such, a set of standards are provided that ensure that required common areas for access, parking,
courtyards, etc. are preserved in joint ownership while the units themselves are provided with their own
distinct areas of private control and ownership, including the dwelling unit and a private outdoor area.
2. Each sublot line must be a minimum of 1.5 feet from the footprint of the associated
dwelling unit, except where dwelling units share a common wall; and
3. Each sublot line must be a maximum of 3 feet from the footprint of the associated
dwelling unit, except that a single sublot line along a side or rear façade of a unit may be
located a maximum of 15 feet from the footprint of the dwelling unit along that facade for the
purpose of providing a private outdoor area that meets the following:
a. The area must be contiguous;
b. The area must be 200 square feet or less, measured as shown in Figure 18.840.1;
c. The area must not have any internal dimension of less than 5 feet; and
d. The area must be accessible from a first-story entrance that is not the primary
entrance to the dwelling unit.
3. All remaining portions of the lot must be placed in one or more tracts under common
ownership.
B. All utilities within a sublot that serve other sublots must be placed in easements.
A. The proposed plat name must not be duplicative.
Figure 18.810.1
[PLACEHOLDER]
18.840.0 60 Approval Criteria—Final Sublot Plat
A final sublot plat will be approved when all of the following are met:
A. The final sublot plat substantially conforms to the approved preliminary sublot plat and all
conditions of approval have been met;
B. The final plat includes the following:
1. A note prohibiting further division of the sublots;
2. Labels and descriptions for all tracts;
3. A reference to any deed restrictions imposed on the lot or sublots as a condition of
approval of the original lot creation, sublot plat, or development approval; and
4. An affidavit by the surveyor who surveyed the land represented on the plat indicating the
land was correctly surveyed and marked with proper monuments and indicating the initial
point of the survey, and giving the dimensions and kind of such monument, and its reference to
some corner established by the U.S. survey or giving two or more objects for identifying its
location.
C. The city’s engineering department has provided written confirmation that a sewage disposal
system will be available to the sublot line of each sublot depicted in the final sublot plat;
D. All public improvements have been installed and inspected in accordance with Section
18.910.190 and have been approved in accordance with Section 18.910.200.
Commentary Chapter 18.840 Sublot Plats
The final sublot plat criteria are related to the recording of the final sublot plat, and include a
requirement that a mechanism for joint ownership and maintenance of common areas be recorded,
similar to the provisions of a condominium plat as provided in ORS 100.
E. A copy of the recorded document establishing a homeowners association to manage all
commonly held areas located in tracts has been provided to the city. At a minimum this document
must include the following:
1. A description of the common elements located in tracts.
2. An allocation to each unit included in the sublot plat of an undivided and equal interest in
the common elements and the method used to establish the allocation.
3. An establishment of use rights for common elements, including responsibility for
enforcement, and
4. A maintenance agreement for common elements, including an allocation or method of
determining liability for a failure to maintain.

The same result can still be achieved through an adjustment or a planned development.
B. Setback averaging. The required setback may be reduced to the average of the existing
setbacks of the lots that are on both sides of the site. See Figure 18.40.13. The following rules apply
in calculating the average:
1. The setbacks used for the calculations must be for the same type of structure that is being
averaged. For example, only garage entrance setbacks may be used to average a garage
entrance setback, and only deck setbacks may be used to average a deck setback.
2. Only the setbacks on the lots that abut each side of the site and are on the same street may
be used. Setbacks across the street or along a different street may not be used.

accessory dwelling unit. In this situation, the square footage limits for accessory structures and for
accessory dwelling units remain in effect.
18.40.130 Residential Density
A. Calculating maximum number of residential units Residential density for apartments and single
detached house development. To calculate the maximum number of residential units per net acre,
divide the number of square feet in the net development area by the minimum number of square feet
required for each lot or dwelling unit in the applicable base zone. The minimum and maximum
density for apartments is provided in Table 18.230.
B. Calculating minimum number of residential units for apartment and single detached house
development. The minimum number of residential units per net acre is calculated by multiplying the
maximum number of units determined in Subsection 18.40.130.A by 80 percent.
Commentary Omnibus Amendments
Removing this provision allowing separate measurement of an ADU built over an existing garage. It was
confusing for both applicants and staff and created a situation that encouraged development of
oversized ADUs through a two-step process in some circumstances.
Updating to clarify that lot standards and development standards are now the primary means of
measuring density except for apartments.
BC. Residential density for other housing types. Minimum and maximum residential density for
cottage clusters, courtyard units, rowhouses, and quads, and small form residential development are
determined by the minimum and maximum lot sizes provided in Chapter 18.805 Lot Standards
and the provided in the applicable development standards chapters for each housing type in
Chapter 18.200.
18.50.020 General Provisions
D. The regulations of this chapter apply to all nonconforming circumstances except the following:

b. Be occupied by small form residential development a single detached house and
accessory structures if located in a residential zone.
C. Nonconforming development.
1. Where a lawful structure or development exists that could not be built under the terms of
this title by reason of restrictions on lot area, lot coverage, height, required parking,
landscaping, or other requirements, such structure or development may remain and its use
continued provided it remains otherwise lawful and complies with the following:
b. If a nonconforming structure, development, or nonconforming portion of a structure
or development is destroyed by any means to an extent of more than 60 percent of its
current value as assessed by the Washington County assessor, reconstruction is prohibited
except in conformity with this title. This prohibition does not apply to small form
residential development single detached houses destroyed by accident. If a
nonconforming small form residential development single detached house is partially or
totally destroyed by accident, such as by fire or earthquake, reconstruction is allowed;

Proposed Zoning
Tigard Code Review
1. In the MUC-1 zone, quads and clusters appear proposed to be not allowed, although SFD
is. Because SFD is allowed in this zone, the other middle housing types must also be
allowed. MUC-1 zone is subject to additional standards in 18.620 so the City will need to bring
those standards into compliance with OAR 660-046 or justify that the standards won’t cause
undue cost and delay to middle housing development.
2. The RES-A zone appears to allow rowhouses (18.110.040) but throughout the development
standards tables, rowhouses are indicated as prohibited in the RES-A zone. Because SFD is
allowed in this zone, the other middle housing types must also be allowed.
3. The RES-D zone appears to require 3 spaces/quad development. With a minimum lot size of
3,000 sf, the OARs requires minimum parking requirements cannot exceed 2 spaces/quad
development.
4. The quadplex proposed parking standards (18.270.040 E) seem more restrictive than the OARs
and Model Code. Cities may require off street parking, based on the minimum lot size in each
base zone.
5. The RES-D zone appears to require a minimum 50 ft lot width for quads, while requiring no
minimum lot width for SFD. The OARs require minimum lot size to be the same or less
restrictive as SFD.
6. It appears the city is proposing a requirement that quadplexes must be configured in a two
up/two down arrangement. Although this requirement is allowable per the OARs, DLCD staff
note that quadplexes built under this requirement will not be eligible for middle housing land
division under SB 458 as they would not be able to meet the 1 unit per lot requirement.
7. The cottage cluster common courtyard standards (18.240.040 D) specifically D1-3 are not design
standards outlined in the Model Code and D5 is more restrictive than the Model Code standards
which state “Cottages must abut the common courtyard on at least two sides of the courtyard”
(C. Design Standards 2.b). Since these standards do not align with the Model Code, the City
should provide justification for how these proposed standards won’t cause undue cost and delay
to middle housing development.
8. Pg 30 (18.240.040 M) OAR 660-046 requires that the building footprint for a cottage in a cottage
cluster development must be less than 900 square feet. A large city may allow up to 200 sf of
attached garage to be excluded from the total building footprint size. A better way to write this
standard would be “The total maximum floor area of a single-story cottage is less than 900
square feet.”
9. The cottage cluster orientation requirements are more restrictive than the Model Code
standards provision C. Design Standards 1C which state “Cottages within 20 feet of a street
property line may have their entrances facing the street.” Please help us understand the
rationale for this standard.
10. If there are other standards that propose more restrictive design and/or siting standards, the
City will need to demonstrate compliance with the criteria of OAR 660-046-0235 Alternative
Siting or Design Standards.
11. Sublot Platting – SB 458 describes in detail the kinds of approval criteria that a city can apply to
an application for a middle housing land division.
(2) A city or county shall approve a tentative plan for a middle housing land division if
the application includes:
a. A proposal for development of middle housing in compliance with the Oregon
residential specialty code and land use regulations applicable to the original lot or
parcel allowed under ORS 197.758 (5);
b. Separate utilities for each dwelling unit;
c. Proposed easements necessary for each dwelling unit on the plan for:
i. (A) Locating, accessing, replacing and servicing all utilities;
ii. (B) Pedestrian access from each dwelling unit to a private or public road;
iii. (C) Any common use areas or shared building elements;
iv. (D) Any dedicated driveways or parking; and
v. (E) Any dedicated common area;
d. Exactly one dwelling unit on each resulting lot or parcel, except for lots, parcels or
tracts used as common areas; and
e. Evidence demonstrating how buildings or structures on a resulting lot or parcel will
comply with applicable building codes provisions relating to new property lines and,
notwithstanding the creation of new lots or parcels, how structures or buildings
located
The bill continues:
(4) In reviewing an application for a middle housing land division, a city or county:
[…]
(c) May not subject an application to approval criteria except as provided in this section,
including that a lot or parcel require driveways, vehicle access, parking or minimum or
maximum street frontage.
The sublot platting process proposed by the city is extensive and appears to apply approval
criteria to applications for middle housing land divisions that would exceed those allowed under
SB 458.
