RE: Determination of setbacks for property at 11020 SW 111 Place.
Dear Mr. Christian:
This letter is to explain the methodology that is used for determining setbacks on
lots within the City of Tigard. First, I would like to express that this particular lot
that you have inquired about located at 11020 SW 111 Place is indeed an
unusual case, based on the position of the road that accesses it. I appreciate that
you brought your concern to us, as it resulted in a spirited discussion of how
setbacks are applied. However, after researching the previous land use approval
for the subdivision, and past and current development codes, the consensus is
that the proposed addition will meet setback requirements. A detailed description
of how this conclusion was made follows.
The first step in applying setbacks is figuring out where the front yard is. The code
defines the front lot line as:
"Front lot line" - In the case of an interior lot, a property line which abuts the
street; in the case of a corner lot, the shortest of the two property lines which abut
the street; except where the narrowest side of a lot is a minimum of 75 feet there
may be a choice of frontage.
In this case, the lot is not a corner lot, so the front lot line is the property line
segment that abuts the street, as shown in the diagrams.
Once the front yard has been determined, the rear yard is next.
"Rear lot line" - The recorded lot line or lines most distant from and generally
opposite the front lot line, except that in the case of an interior triangular lot or
lot with more than four sides, it shall mean a straight line ten feet in length
which is parallel to the front lot line or its chord and intersects the other lot lines
at points most distant from the lot line.
As this lot has more than four sides, as illustrated in the diagram, the rear lot line is
established by a straight line, ten feet in length, and parallel to the front lot line.
This straight line is placed opposite the front lot line and "slides down" the east
property line until it comes to a point of intersecting the other lot lines. This
establishes the rear lot line, and the reference point for drawing the rear yard
setbacks.

Once the front and rear yards have been established, everything else becomes a
side yard.
"Side lot line" - Any lot boundary not a front or rear lot line.
The application of these setbacks is shown in Figure 2. The setbacks for this
subdivision are generally 15' front yard, 20' to the garage, 15' rear yard, and 5'
side yard. Some exceptions apply to corner lots, but no specific exception applies
to this particular lot.
