ENVIRONMENTAL REVIEW COMMITTEE REPORT
ERC MEETING DATE: October 9, 2023
Project Name: PR23-000002 2023 Docket #18D, Code Interpretations & International Building Code
Adoption
Project Number: LUA23-000326, ECF
Project Manager: Angie Mathias, Long Range Planning Manager
Owner: City of Renton
Applicant: City of Renton
Contact: Angie Mathias, 425-430-6576
Project Location: All docket items are citywide.
Project Summary: D-231: Codification of seven code interpretations - CI-169 applied the same standards
in the RMF zone as all other zones where townhomes are allowed. CI-176 clarified that
density applies to hotels used for permanent supportive housing and transitional
housing and that full kitchens and bathrooms are part of those dwelling units. CI-177
increased the threshold for requiring frontage improvements from $150,000 to
$175,000. CI-178 corrected the setback for residential accessory structures, including
ADU’s, from 6’ to 4’. CI-179 struck a reference to minimum tree density in the
development regulations; this was intended to be done with the tree regulations
docket item. CI-181 amended the Shoreline Master Program as requested by the
Department of Ecology; specifically citing the adopting ordinance number and date,
stating that the SMP prevails if there is a conflict, increased the dollar amount that
constitutes Substantial Development, and amended two tables to ensure clarity. CI-
182 clarified that criteria C through E should also be considered when reviewing
applications for waivers for street improvements.
D-232: International Building Code Adoption – The State Building Code Council has
adopted the 2021 International Building Code Building Code with three amendments.
The City of Renton would also like to adopt Appendix T related to solar panel readiness
for single and two family homes. Code needs to be amended to be consistent with the
new State requirements and will also be amended to strike portions related to Fire
standards that are now codified with the Renton Regional Fire Authority.

PART ONE: PROJECT DESCRIPTION / BACKGROUND
#D-231 Code Interpretations Administrative Policy and Code Interpretations are binding interpretations of land use
codes administered by the City. Draft interpretations are posted online and public comments may be provided during
a 14 day comment period following the posting. Interpretations are then issued at the end of the comment period,
subject to comments received. The interpretation may be appealed provided it is filed with the City's Hearing
Examiner within 14 days from the date of issuance. None of these Code Interpretations had comments received and
none were appealed. This docket item is to codify a group of code interpretations.
CI-169 The Residential Multi-Family (RMF) zone is the primary zone to allow standalone multi-family
development. Historically, this zone has been developed with “attached flats” (i.e., apartments) and garden
style apartments (a dwelling unit that is one of several stacked vertically, with exterior stairways and/or
exterior corridors and surface parking.) The existing design standards were developed to focus on these land
use types. Due to trends in residential construction, townhome development has become more prevalent in
the RMF zone compared to other multi-family housing types. Townhomes, except the RMF, are subject to the
standards of RMC 4-2-115, Residential Design and Open Space Standards. Code requires that projects
developed under the Unit Lot Subdivision process in the RMF zone shall be subject to RMC 4-2-115, implying
that townhome development not utilizing the Unit Lot Subdivision process would not be subject to RMC 4-2-
115. Additionally, RMC 4-3-100, Urban Design Regulations, notes that all new structures in the RMF zone shall
be subject to Urban Design District ‘B’ design regulations. However, it was not the intent of Design District B
to apply to townhome development. As the standards of RMC 4-2-115 are currently applied to Unit Lot
Subdivisions in the RMF zone, staff proposes that townhome development in the RMF zone should follow the
Unit Lot Subdivision process, therefore clarifying which standards should apply to proposed townhome
development in the RMF zone.
CI-176 clarified standards which Permanent Supportive Housing (PSH) and Transitional Housing (TH) use when
they occur in zones that do not allow other housing types. In 2021, Washington State passed House Bill 1220
which required jurisdictions to allow PSH and TH in any zone that allows hotels or dwelling units. In 2021, with
docket item D-200 Renton adopted regulations to be compliant with HB 1220, but the identification of a
density that would apply to PSH and TH in zones that allow for hotels, but not dwelling units was not
established. Additionally, it was recognized that if PSH or TH were to occur in one of these zones they would
need to comply with the requirements for housing, not hotels. This Code Interpretation resolved both of those
things. Additionally, staff revised the definitions of PSH, TH, Emergency Shelter, and Emergency Housing to
reference back to the Revised Code of Washington anticipating further amendments from the Legislature and
to remain compliant with their future revisions.
First, clarify that density does apply to PSH and TH in all Industrial zones west of Rainier Avenue and/or State
Route 167, throughout the Commercial Office (CO) zone, and in the Commercial Arterial (CA) zone in the
Benson, Cedar, Talbot, and Valley Community Planning areas. Also, a standard of 30 dwelling units per acre
for PSH and TH in those zones was identified. Second, the definition of dwelling unit was amended to more
closely align with International Building Code, specifying that a kitchen and is part of a dwelling unit and that
sanitary facilities means a sink, toilet, and a shower or bathtub are part of a dwelling unit. Next, a new
definition for Kitchen was established.
CI-177 increased the threshold for when a home addition or new construction is exempted from the
requirements to install frontage improvements. The dollar value was increased from $150,000 to $175,000.
The intent of the Code is to allow for small projects without triggering the need for property owners to put in
sometimes very costly sidewalks, planting strip and curbs. The dollar value was last adjusted in 2017 and

construction costs have increased since then. The adjustment was necessary to remain consistent with the
intent of the code.
CI-178 As part of Docket Item D-199, Residential Accessory Structures, staff proposed code amendments to
reduce the required separation between residential structures from six feet (6’) to four feet (4’), including
detached accessory structures and accessory dwelling units (ADUs). In the same docket cycle, staff proposed
unrelated ADU code amendments via Docket Item D-191, ADUs as Accessory Uses to Religious Institutions.
Ordinance 6049 adopted amendments related to D-199, including amendments to RMC 4-2-110.B,
Development Standards for Residential Development (Detached Accessory Buildings), which reduced the
required separation between residential structures from 6 feet to 4 feet. Ordinance 6046 adopted
amendments related to D-191 and was intended to include the proposed amendments to RMC 4-2-110.C,
Development Standards for Residential Development (Accessory Dwelling Units), as proposed via D-199, but
this amendment was erroneously omitted. This CI amended code to 4’ separation.
CI-179 strikes a portion of the Development Regulations Table that was inadvertently omitted from D-197
Tree Regulations in 2022. One of the changes the docket item made was to shift from using Minimum Tree
Density to a Tree Credit system to determine how many trees need to be provided and/or retained for land
use actions. A line in a different code section than the Tree Retention and Land Clearing Regulations referred
to the Minimum Tree Density and was not stricken as part of the docket ordinance. This CI strikes that item in
the table.
CI-181 makes amendments to the Shoreline Master Program (SMP) in order to comply with requirements
from the Department of Ecology. On November 20, 2019, Ecology provided the city with an initial
determination of consistency with the policy of the Shoreline Management Act (SMA) and applicable rules.
The city’s final adopted ordinance incorporated most of Ecology’s required and recommended changes
provided as part of the initial determination, however Ecology identified some inconsistencies and requested
some additional recommended changes to provide clarity and consistency of implementation. The CI identifies
the specific date and ordinance number the SMP was adopted, Ordinance Number 5976, on August 3, 2020.
It specified that if there is a conflict between the SMP and the Critical Areas Ordinance, that the SMP shall
prevail. The dollar threshold codified in the SMP is $7,047, Effective July 1, 2022, the dollar threshold for
substantial development was increased to $8,504. So, that amount was increased. Lastly, two tables were
amended to further emphasize the already established standards.
CI-182 ORD. 5981 revised criteria for waivers of street improvements to clarify that a street waiver must
ensure that it will not have a negative impact on other properties and that it will have a de minimis effect on
public health, safety or welfare if the improvements were not installed. If the aforementioned criteria are
met, additional justification may include, but is not limited to: improvements that would also harm critical
areas, improvements that will be installed as part of a City project, and if existing street topography would
make the required street improvements infeasible. As adopted, the decision criteria waivers of street
improvements could be misinterpreted to mean the later criteria beyond the first two are not requirements
to receive a waiver of the street improvements. A code interpretation specifying all criteria are required was
needed to avoid ambiguity that could lead to misinterpretation and incorrect application of code.
D-232 International Building Code Adoption - A new 2021 version of State, National, Uniform and International
Building Codes has been adopted by the State Building Code Council (SBCC) and it is to become effective March 15,
2024. Renton Municipal Code need to be amended to comply with these standards. Additionally, sections related to
Fire Code should be deleted and an optional appendix is recommended for adoption.

The SBCC was created to advise the Legislature on building code issues and to develop the building codes used in
Washington State. These codes help to ensure buildings and facilities constructed in the State are safe and healthy for
building occupants, accessible to persons with disabilities and the elderly, and energy efficient. The SBCC adopts these
codes with some required appendices and makes other appendices optional for local jurisdictions. Renton Municipal
Code currently references the 2018 version. The SBCC has authority to adopt amendments to these codes for
statewide applicability. They have adopted Residential Code Appendix Q regarding tiny homes, Appendix U regarding
dwelling unit fire sprinklers, and Appendix E for supplementary accessibility. Renton Code needs to be amended to
reflect the current 2021 IBC and the required appendices. In 2022, the Renton Regional Fire Authority adopted the
International Fire Code. The current code chapter 4-5-060 has many requirements related to fire code that are now
in the Fire Code. Staff recommends these sections be stricken.
Staff also recommends that the City also adopt Appendix T, solar-ready provisions for one and two family dwelling
units. Adoption of Appendix T is consistent with the goals and policies of the Clean Economy Strategy 2.0. This
appendix will require new construction of single-family dwellings and duplexes to build roofing structures that will be
able to accommodate solar panels in the future. Requiring this of new residential construction of single-family
dwellings and duplexes may slightly increase the cost of construction that likely will affect the sale price. However,
that cost is estimated to be much less than a retrofit later in order to have adequate support for installation of solar
panels.
