PLANNING COMMISSION REVIEW
CASE NUMBER: L17-0067, Accessory Dwelling Unit Regulation Update (ADU)
APPLICANT: City of Tukwila
REQUEST: Update of regulations for ADUs including allowing detached ADUs with
design and height requirements, lowering the lot size requirement,
modifying the parking requirement, removing ADUs as accessory uses in
non-residential zones, limiting rental of ADUs to periods of 30 days or more
and providing an amnesty period for existing ADUs.
LOCATION: Citywide
Nora Gierloff
, Deputy Director, Department of Community Development gave background on the
process for updating the ADU regulations. She said City Council held a series of housing
workshops and looked at a variety of options for improving housing supply and affordability in the
City. Then, City Council requested staff work on updating ADU regulations, to make them more
flexible to encourage this type of housing. Staff currently has a list of 130 interested individuals
they are keeping updated as they move through the process. Tonight, staff has returned to the PC
with ordinance language to implement the policy choices that the PC made at the October meeting.
Also, staff proposed four additional changes:
1) Add the proposed definition in the Zoning Code for ADUs;
2) Restrict ADUs to only residential zones because they are a single-family type use and would be
incompatible with the noise and lighting in commercial areas.

3) Include the following language as a place holder in the short-term rentals policy, ‘no rentals for
less than 30 days’, staff will review this issue in detail and revise later if necessary.
4) Allow ADUs to be built in front of the main house where the house is set back at least 60 feet
from the front property line.
The PC was in consensus with the proposed changes 1-4. There was no public testimony.
Staff addressed clarifying questions for the Commission. Following are some of the noted issues
discussed:
Commissioner Watters was opposed to the language in the ADU definition requiring
ADUs to be ‘clearly subordinate’ to the primary dwelling unit.
Commissioner Mann said she is against including the garage in the square footage that is
used to calculate the maximum size of an attached ADU; Commissioner Nguyen is in
favor of including the garage.
Parking concerns were expressed and discussed extensively and re-visited several times.
Commissioner Mann said she is against waiver of the second parking space for ADUs
over 600 sq. ft. where there is on-street parking and suggested retaining the requirement
that ADUs over 600 sq. ft. have two parking spaces. Commissioner Strander agreed.
Commissioner Nguyen said he prefers the proposed waiver.
Commissioner Mann discussed the idea that ADUs should have higher side yard
setbacks.
