DATE: July 3, 2006
CODE SECTIONS: 18.120 Definitions
18.510.060 Residential Zones Accessory Structures
TOPIC: What is the distinction between an Addition and an Accessory Structure?
DIRECTOR'S INTERPRETATION:
I. Introduction:
"Accessory buildings or structures," are permitted in all zones in Tigard. They are
defined in '1'DC 18.120 as' "a freestanding structure incidental and subordinate to the
main use of property and located on the same lot as the main use."
An issue has arisen over structures that have been permitted to be built in residential
zones without being subject to the limits of 18.510.060.A.1. Building permits were
approved for these structures due to the ambiguity of what constitutes an "accessory
structure" and what constitutes an "addition." These terms need to be clarified.
II. Interpretation:
A structure is considered an "Accessory Structure" and not an "Addition," when it is
"freestanding." A structure is freestanding when it is structurally separated from the
primary or any existing structure and not attached to the primary or any existing
structure. Structures that are connected by breezeways, features made of lattice,
archways, trellises, or other similar architectural features shall not be considered
attached, but be treated as Accessory Structures.
A structure is considered attached, and therefore an "addition," only when it is
structurally dependent on the primary structure.

Definition:
Accessory Structure & Addition in Residential Zones
INTERPRETATION: DISTINCTION BETWEEN AN ADDITION AND AN ACCESSORY STRUCTURE
1. Introduction:
"Accessory buildings or structures," are permitted in all zones in Tigard. They are defined
in Tigard Development Code Section 18.120 as "a freestanding structure incidental and
subordinate to the main use of property and located on the same lot as the main use."
An issue has arisen over structures that have been permitted to be built in residential
zones without being subject to the limits of Section 18.510.060.A.1. Building permits were
approved for these structures due to the ambiguity of what constitutes an "accessory
structure" and what constitutes an "addition." These terms need to be clarified.
2. Interpretation:
A structure is considered an "Accessory Structure" and not an "Addition," when it is
"freestanding." A structure is freestanding when it is structurally separated from the
primary or any existing structure and not attached to the primary or any existing structure.
Structures that are connected by breezeways, features made of lattice, archways, trellises,
or other similar architectural features shall not be considered attached, but be treated as
Accessory Structures.
A structure is considered attached, and therefore an "addition," only when it is structurally
dependent on the primary structure.
