INFORMATIONAL MEMORANDUM
TO: Planning and Community Development Committee
CC: Mayor Thomas McLeod
FROM: Nora Gierloff, AICP, DCD Director
BY: Neil Tabor, AICP, Senior Planner
DATE: April 14, 2025
SUBJECT: Removing Townhouses as a Permitted Use in the Tukwila Urban Center
ISSUE
The proposed code amendment to remove townhouses as a Permitted use in the Tukwila Urban
Center would improve alignment of the City's planned density goals for the Urban Center by
removing a housing type that would not support attainment of the required density.
BACKGROUND
The Tukwila Urban Center is a regional
center designated with the Puget Sound
Regional Council for future growth,
capitalizing on transit infrastructure to
reduce car dependency. This Center
designation under the Regional Growth
Strategy, makes this area eligible for
additional transportation funding that can
improve these areas and help them
transition into denser transit -oriented
development over time. Under Puget Sound
Regional Growth Center standards, one of
requirement for a Center is that it plan for a
minimum of 45 "activity units" per acre. This
metric is a summation of jobs and housing
units per acre.
Currently, the Tukwila Urban Center
contains approximately 22 activity units per
acre, about half of the density for which the
area is planned. This total is supported
largely through area jobs, with recent
housing growth in the last ten years
beginning to help support the targeted activity
figure 70-7. Tukwiias Urban Center(5err fhcur ier) Boundaries
unit total.

PLANNING COMMISSION RECOMMENDATION
A public hearing on code amendment L25-0002 was held at the January 23rd, 2025, Planning
Commission meeting. Commissioners entertained a motion to recommend that the City Council
adopt the code amendment to remove townhouses as a permitted use within the Tukwila Urban
Center, as included in the attached ordinance. An amendment was proposed to permit
townhouses only as an accessory use, instead of strictly removing townhouses as a permitted
use. The Commission's vote was split 3 to 3 on this amendment to language proposed by the
City. The language proposed in the attached ordinance reflects the original proposal as
presented by staff without amendment.
A link to the Planning Commission packet materials on this topic is provided here. Minutes of
the January 23rd Planning Commission meeting are included in the packet as an attachment.
ANALYSIS
As the City plans for additional growth in the Urban Center, redevelopment should be
encouraged to meet or exceed the minimum activity unit density planned for the area. While this
naturally occurs, in part, from market demand and property values, development allowances
should encourage uses which align with this density and should not permit uses that are not
expected to support this density. Townhouses are one such use currently permitted in the TUC
— Regional Center, TUC — Pond, TUC — TOD and partially within the TUC — Work Place zoning
districts, that would likely not meet the minimum density of 45 activity units per acre, if
developed. Generally, townhouses, even when constructed in an especially dense manner,
would not be expected to reach 30 units per acre. As townhouses will likely be permitted
throughout other residential zones within the City after the adoption of middle housing updates,
staff believes townhouses should be removed from the Tukwila Urban Center zones.
Language about comments received:
The City received comments from a property owner in the TUC-TOD district wishing to maintain
the ability to develop townhouses in relative proximity to the Green River shoreline. Shoreline
regulations apply to the first 200 feet from the river, and limit overall development allowed
within this buffer. Staff do not support the addition of this exception as the City has committed to
ensuring that development planned within its Urban Center supports the designated activity unit
totals.
SUMMARY OF PROPOSED CHANGES
Staff proposes removing townhouses from the list of allowed dwelling types in Table 18-2,
affecting the Tukwila Urban Center Regional Center, Transit Oriented Development and Pond
Zoning Districts.

Staff Report Criteria
P
P
TMC 18.82.030 requires that staff reports for proposed amendments to development regulations
address the five listed criteria in this section. As criteria pertain to both privately initiated code
amendment applications and those proposed by the City, some criteria may not be as relevant
for all code amendment proposals. Criteria and staff responses are listed below.
1. An evaluation of the application materials;
Staff Response: Not applicable.
2. Impact upon the Tukwila Comprehensive Plan and Zoning Code;
Staff Response: The proposed code amendment is consistent with the comprehensive plan and
does not require an amendment to the comprehensive plan.
3. Impact upon surrounding properties, if applicable;
Staff Response: Not applicable.
4. Alternatives to the proposed amendment; and
Staff Response: The City could consider two possible alternatives: 1) the City could continue to
allow townhouses in the Urban Center, but allow them only an accessory use to another primary
use, or 2) the City could make no changes in the code, and continue to allow townhouses in the
Urban Center. Staff does not support either of these options, as they weaken or negate the
City's commitment to achieve planned housing and redevelopment densities required for the
Urban Center.
5. Appropriate code citations and other relevant documents.
Staff Response: More information on Tukwila's Urban Center profile can be found here.
Decision Criteria
TMC 18.82.020, Decision Criteria provides criteria for the final City Council decision on
proposed code amendments.
Decision criteria are as follows:
1. Is the amendment consistent with the Comprehensive Plan?
2. Does the amendment meet at least one of the following criteria;
a. Eliminates conflicts between TMC and the Comprehensive Plan; or
b. Accomplishes policy directives of the Council or Administration; or
c. Corrects an error or errors in the TMC.
FINANCIAL IMPACT

PUBLIC HEARING
1. Shelter, Transitional, Emergency, Permanent (STEP) Housing Changes
FILE NUMBER: L24-0026, E25-0001
PURPOSE: Code amendment to comply with state law.
LOCATION: Non -Project Action/Citywide
Senior Planner Neil Tabor gave the presentation for staff. He provided background on STEP Housing
and the purpose of the public hearing. He said that legislature narrowed restrictions for the STEP
Housing types, which resulted in the allocation of certain housing targets. The City of Tukwila
previously adopted code amendments to recognize the STEP Housing types. In 2021, the State
legislature passed HB 1220 which sets requirements for STEP Housing. The following housing types are
not included:
• Temporary Encampments
• Tiny Home Villages
• Group Homes
• Oxford Homes/Recovery Residence
• Assisted Living Facility
• Adult Family Homes
• Senior Living
• Traditional Income -Restricted Housing
Staff noted that the State, Puget Sound Regional Council, and Countywide King County each
commented that the city's current development regulations do not meet requirements. Staff went over the
proposed standards and walked through the STEP housing requirements in which the City of Tukwila is
not in compliance.
To meet state law requirements and provide capacity to site the city's allotted amount of STEP Housing,
while maintaining reasonable occupancy and spacing requirements, staff propose to amend TMC
18.50.250, 18.50.260 and Table 18-2 Tukwila Urban Center (TUC) Land Uses Allowed by District
Staff addressed clarifying questions from the PC.
Recommendation
Staff are requesting that the Planning Commission forward a recommendation for adoption of the draft
code amendments to the City Council (CC) for their review.
Public Hearing
Chair Probst opened the public hearing.
Staff noted that there were no public hearing comments letters received.

2. Phased Binding Site Improvement Plans (BSIP)
FILE NUMBER: L25-0001, E25-0002
PURPOSE: Code amendment to remove development agreement requirement.
LOCATION: Non -Project Action/Citywide
Senior Planner Neil Tabor gave the presentation for staff. He provided background on the proposed.
BSIPs are plans used to provide flexibility for sale of property within a larger development. These
developments often rely on shared features within the larger site, such as: Parking; access points;
landscaping; utilities; refuse collection areas; etc. Phased BSIPs improvement plans and proposals to
develop in phases are required to enter into a development agreement in addition to completing the
BSIP.
The requirement for phased BSIPs to execute a development agreement is listed in the Tukwila
Municipal Code (TMC) 17.16.030(C) Preliminary Binding Site Improvement Plan (BSIP) approval,
approval Criteria.
Staff proposed removing the sole provision requiring the execution of a development agreement with
phased BSIPs. References requiring consistency with approvals and options to apply conditions and
limitations for phased BSIPs are already present in other sections of TMC 17.16 and throughout the
TMC.
Staff addressed clarifying questions from the PC.
Recommendation
Staff are requesting that the Planning Commission forward a recommendation for the adoption of the
draft code amendments to the CC for their review.

3. Townhouses in the TUC
FILE NUMBER: L25-0003, E25-0004
PURPOSE: Code amendment to update residential allowances.
LOCATION: Non -Project Action/Citywide
Senior Planner Neil Tabor gave the presentation for staff. He provided background on the proposed. He
stated this item is on townhouse allowances in the TUC, which is a regional center designated with the
Puget Sound Regional Council for future growth, capitalizing on transit infrastructure to reduce car
dependency. This center designation under the Regional Growth Strategy makes this area eligible for
additional funding that helps them transition into denser, transit -oriented development over time. It
covers Pierce, Snohomish, King, and Kitsap Counties. Within these counties, centers can be designated
where high capacity transit exists, encouraging the greater use of public transportation.
Part of the requirement for a center is that it plans for a minimum of 45 "activity units" per acre.
Staff proposes removing townhouses from the list of allowed dwelling types in table 18-2, affecting the
TUC Regional Center, Transit Oriented Development, Pond and portions of the Work Place Zoning
Districts.
Staff are requesting that the PC forward a recommendation for the adoption of the proposed redlined
language to the CC for their further review and adoption.
Staff addressed clarifying questions from the PC.
Commissioner Halverson stated that he would propose an amendment, stating he is against removing
townhomes from the use in the TUC.
Commissioner Durant stated it was mentioned in the staff background report that regional growth
strategy designation makes the area eligible for additional funding. She asked if townhomes are not
stricken and allow zoning that wouldn't meet the 45 activity units whether the City of Tukwila would be
ineligible for the funding or would it be less accessible to the city. She said the change makes sense to
her. Mr. Tabor stated individual use allowances would be unlikely to eliminate funding eligibility, but
regulations should be consistent with goals for the center.
Commissioner Halverson inquired whether there is any concept to build small townhouse -style
residential.
Staff said they identified this as something that is inconsistent with the overall goals, which is why they
are proposing it.

Commissioner Halverson moved to forward the split recommendation to the CC for their review.
Commissioner Stander seconded the motion. Motion carried.

PUBLIC HEARING
4. Residential Conversions
FILE NUMBER: L25-0002, E25-0003
PURPOSE: Code amendment to comply with changes in state law.
LOCATION: Non -Project Action
Senior Planner Neil Tabor gave the presentation for staff. He provided background on the proposed
amendment. He stated that in the 2023 legislative session, HB 1042 passed and broadened allowances
for conversions of non-residential to residential spaces. Per the Municipal Research and Services Center
(MRSC) he went over several of the key provisions of the requirements. He said the intent with this code
amendment is to provide consistency with the state law. Also, to provide future allowances that the city
can still maintain ground floor commercial space that is required in new use development and identified

INFORMATIONAL MEMORANDUM
TO: Planning and Community Development Committee
CC: Mayor Thomas McLeod
FROM: Nora Gierloff, AICP, DCD Director
BY: Neil Tabor, AICP, Senior Planner
DATE: April 14, 2025
SUBJECT: Proposal to Amend Regulations Relating to Conversion of Existing
Building Space to Residential
ISSUE
The proposed code amendment would bring the City into compliance with upcoming changes in
state law and designate an area for preservation of ground floor commercial space.
BACKGROUND
In the 2023 legislative session, the state legislature passed HB 1042, a bill broadening the
required allowances for conversion of non-residential buildings, or non-residential portions of
buildings, into residential spaces (since codified as RCW 35A.21.440) . The intent of this bill
was to encourage conversion of underutilized office and commercial space into much needed
residential units. The viability of individual buildings being converted may differ, based on
building characteristics. The City is required to adopt code that is compliant with the bill within
six months after the adoption of the comprehensive plan, or by June 30, 2025.
As summarized by the Municipal Research and Services Center (MRSC), some of the key
provisions of the bill requirements include:
• Allowing a 50% density increase above what is permitted in the underlying zone if the
housing is constructed entirely within the envelope of an existing building, provided that
generally applicable health and safety standards can be met;
• Prohibiting the imposition of parking standards on the additional dwelling units;
(however, cities may require retention of existing parking required to satisfy existing
residential parking requirements under local law and for any nonresidential uses that
remain after new units are added);
• Prohibiting imposing additional permitting requirements on use of existing buildings
beyond those applicable to all residential development in the zone, with the exception of
emergency and transitional housing;
• Prohibiting the imposition of additional design standards beyond those generally
applicable to all residential development in the zone;
• Prohibiting requiring that unchanged portions of an existing building used for residential
purposes meet the current energy code; (however, if any portion of an existing building
is converted to new dwelling units, the new units must meet the current energy code);
and
17
Page 2
• Prohibiting denial of a building permit based on certain existing nonconformities unless a
city official with decision -making authority makes findings that the nonconformity is
causing a significant detriment to the surrounding area.
Other key provisions of the bill include:
• Provisions apply to all zones permitting multifamily development, and all structures that
have received a certificate of occupancy at least three years prior.
• Developments along designated "Major Pedestrian Corridors", as defined by the
individual jurisdiction, may restrict conversion of otherwise qualifying ground floor
building space if there is a code requirement for non-residential ground floor space.
PLANNING COMMISSION RECOMMENDATION
A public hearing on the code amendment L25-0002 was held at the January 23rd, 2025,
Planning Commission meeting. Commissioners passed a motion to recommend that the City
Council adopt the code amendments without modifications. A link to the Planning Commission
packet materials on this topic is provided here.
SUMMARY OF PROPOSED CHANGES
Staff proposes adopting a new code section as TMC 18.50.230 "Residential Conversions",
clarifying residential conversion allowances and standards, and adopting a map designating
parcels within a Major Pedestrian Corridor, depicted in Figure 1. Language regarding residential
conversions in zones affected by these provisions are also noted in individual chapters.
A new definition of "Residential Conversion" is also proposed in TMC 18.06 for clarity, as copied
below.
"Residential Conversion" means the conversion of a building, or portion of a building, that is
vacant, or occupied by a nonresidential use, to a residential use.

ANALYSIS
Preserving ground floor uses and requiring ground floor commercial uses in select residential
development circumstances can provide a variety of public benefits and support fulfillment of
comprehensive plan goals and policies. Ground floor commercial spaces can help foster
placemaking, support denser transit -oriented development, provide spaces for local businesses
and options for local shoppers, amongst other benefits. Many of the comprehensive plan
policies to achieve these goals are focused along the TIB corridor, which is transit rich, but
currently lacks significant walkable commercial opportunities outside of a select few nodes. Staff
anticipates revisiting zoning and development regulations in the future, which will likely include
evaluating ground floor commercial requirements in mixed use developments.
In the interest of preserving the ability to maintain ground floor commercial spaces, staff
proposes to adopt a Major Pedestrian Corridor along Tukwila International Boulevard as
depicted in Figure 1 above.
Staff Report Criteria
TMC 18.82.030 requires that staff reports for proposed amendments to development regulations
address the five listed criteria in this section. As criteria pertain to both privately initiated code
amendment applications and those proposed by staff, some criteria may not be as relevant for
all code amendment proposals. Criteria and staff responses are listed below.
1. An evaluation of the application materials;
Staff Response: Not applicable.
2. Impact upon the Tukwila Comprehensive Plan and Zoning Code;
Staff Response: The proposed code amendment is consistent with the comprehensive plan and
does not require an amendment to the comprehensive plan.
3. Impact upon surrounding properties, if applicable;
Staff Response: Not applicable.
4. Alternatives to the proposed amendment; and
Staff Response: The City is required to update development regulations to comply with RCW
35A.21.440 by no later than six months after adoption of its comprehensive plan periodic
update. The City has flexibility in choosing whether to establish a major pedestrian corridor to
prevent the conversion of required ground floor commercial space and where to locate this
corridor designation(s).
The designation of the major pedestrian corridor along Tukwila International Boulevard was
determined by staff to be a logical area of emphasis for continued transition to a less
automotive -oriented district. If modifications to the initial proposed corridor geography are
desired, this could be addressed in future code amendments.
5. Appropriate code citations and other relevant documents.
Staff Response: Standards specific to conversion of non-residential space to residential, and
associated preemptions such as minimum density allowances, do not currently exist in the
Tukwila Municipal Code. This ordinance proposes to incorporate this recent legislative
requirement.

Decision Criteria
TMC 18.82.020, Decision Criteria provides criteria for the final City Council decision on
proposed code amendments.
Decision criteria are as follows:
1. Is the amendment consistent with the Comprehensive Plan?
2. Does the amendment meet at least one of the following criteria:
a. Eliminates conflicts between TMC and the Comprehensive Plan; or
b. Accomplishes policy directives of the Council or Administration; or
c. Corrects an error or errors in the TMC.
FINANCIAL IMPACT
No direct costs to the City are expected from this code amendment.
REQUESTED ACTION
The Council is being asked to approve an ordinance to adopt a new code section addressing
"Residential Conversions" clarifying residential conversion allowances and standards; adopting
a new definition and other associated code modifications; and adopting a map designating
parcels within a Major Pedestrian Corridor, depicted in Figure 1. The Council is asked to
consider this code amendment at the April 28, 2025, Committee of the Whole meeting, and
subsequent May 5, 2025, Regular meeting.

PUBLIC HEARING
1. Shelter, Transitional, Emergency, Permanent (STEP) Housing Changes
FILE NUMBER: L24-0026, E25-0001
PURPOSE: Code amendment to comply with state law.
LOCATION: Non -Project Action/Citywide
Senior Planner Neil Tabor gave the presentation for staff. He provided background on STEP Housing
and the purpose of the public hearing. He said that legislature narrowed restrictions for the STEP
Housing types, which resulted in the allocation of certain housing targets. The City of Tukwila
previously adopted code amendments to recognize the STEP Housing types. In 2021, the State
legislature passed HB 1220 which sets requirements for STEP Housing. The following housing types are
not included:
• Temporary Encampments
• Tiny Home Villages
• Group Homes
• Oxford Homes/Recovery Residence
• Assisted Living Facility
• Adult Family Homes
• Senior Living
• Traditional Income -Restricted Housing
Staff noted that the State, Puget Sound Regional Council, and Countywide King County each
commented that the city's current development regulations do not meet requirements. Staff went over the
proposed standards and walked through the STEP housing requirements in which the City of Tukwila is
not in compliance.
To meet state law requirements and provide capacity to site the city's allotted amount of STEP Housing,
while maintaining reasonable occupancy and spacing requirements, staff propose to amend TMC
18.50.250, 18.50.260 and Table 18-2 Tukwila Urban Center (TUC) Land Uses Allowed by District
Staff addressed clarifying questions from the PC.

Staff are requesting that the Planning Commission forward a recommendation for adoption of the draft
code amendments to the City Council (CC) for their review.

2. Phased Binding Site Improvement Plans (BSIP)
FILE NUMBER: L25-0001, E25-0002
PURPOSE: Code amendment to remove development agreement requirement.
LOCATION: Non -Project Action/Citywide
Senior Planner Neil Tabor gave the presentation for staff. He provided background on the proposed.
BSIPs are plans used to provide flexibility for sale of property within a larger development. These
developments often rely on shared features within the larger site, such as: Parking; access points;
landscaping; utilities; refuse collection areas; etc. Phased BSIPs improvement plans and proposals to
develop in phases are required to enter into a development agreement in addition to completing the
BSIP.
The requirement for phased BSIPs to execute a development agreement is listed in the Tukwila
Municipal Code (TMC) 17.16.030(C) Preliminary Binding Site Improvement Plan (BSIP) approval,
approval Criteria.
Staff proposed removing the sole provision requiring the execution of a development agreement with
phased BSIPs. References requiring consistency with approvals and options to apply conditions and
limitations for phased BSIPs are already present in other sections of TMC 17.16 and throughout the
TMC.
Staff addressed clarifying questions from the PC.
Recommendation
Staff are requesting that the Planning Commission forward a recommendation for the adoption of the
draft code amendments to the CC for their review.

PUBLIC HEARING
3. Townhouses in the TUC
FILE NUMBER: L25-0003, E25-0004
PURPOSE: Code amendment to update residential allowances.
LOCATION: Non -Project Action/Citywide
Senior Planner Neil Tabor gave the presentation for staff. He provided background on the proposed. He
stated this item is on townhouse allowances in the TUC, which is a regional center designated with the
Puget Sound Regional Council for future growth, capitalizing on transit infrastructure to reduce car
dependency. This center designation under the Regional Growth Strategy makes this area eligible for
additional funding that helps them transition into denser, transit -oriented development over time. It
covers Pierce, Snohomish, King, and Kitsap Counties. Within these counties, centers can be designated
where high capacity transit exists, encouraging the greater use of public transportation.
Part of the requirement for a center is that it plans for a minimum of 45 "activity units" per acre.
Staff proposes removing townhouses from the list of allowed dwelling types in table 18-2, affecting the
TUC Regional Center, Transit Oriented Development, Pond and portions of the Work Place Zoning
Districts.
Staff are requesting that the PC forward a recommendation for the adoption of the proposed redlined
language to the CC for their further review and adoption.
Staff addressed clarifying questions from the PC.
Commissioner Halverson stated that he would propose an amendment, stating he is against removing
townhomes from the use in the TUC.
Commissioner Durant stated it was mentioned in the staff background report that regional growth
strategy designation makes the area eligible for additional funding. She asked if townhomes are not
stricken and allow zoning that wouldn't meet the 45 activity units whether the City of Tukwila would be
ineligible for the funding or would it be less accessible to the city. She said the change makes sense to
her. Mr. Tabor stated individual use allowances would be unlikely to eliminate funding eligibility, but
regulations should be consistent with goals for the center.
Commissioner Halverson inquired whether there is any concept to build small townhouse -style
residential.
Staff said they identified this as something that is inconsistent with the overall goals, which is why they
are proposing it.

4. Residential Conversions
FILE NUMBER: L25-0002, E25-0003
PURPOSE: Code amendment to comply with changes in state law.
LOCATION: Non -Project Action
Senior Planner Neil Tabor gave the presentation for staff. He provided background on the proposed
amendment. He stated that in the 2023 legislative session, HB 1042 passed and broadened allowances
for conversions of non-residential to residential spaces. Per the Municipal Research and Services Center
(MRSC) he went over several of the key provisions of the requirements. He said the intent with this code
amendment is to provide consistency with the state law. Also, to provide future allowances that the city
can still maintain ground floor commercial space that is required in new use development and identified
areas.
