DATE: January 11, 2021
SUBJECT: Adoption of the 2018 Washington State Building Codes
ISSUE
The State Building Code Council was scheduled to adopt the 2018 Washington State Building Codes with a
statewide effective date of July 1, 2020. However, the statewide effective date has been changed to February
1, 2021. Shall the City Council approve the adoption of the 2018 State Building Codes with amendments?
BACKGROUND
The State Building Code Council was created to advise the legislature on building code issues and to develop
the building codes used in the State of Washington. In the course of development of the State Building Code
the Council holds public hearings, considers proposed state amendments and finally adopts the international
model codes and amendments.
DISCUSSION
Adoption of the State Building Codes by the City Council is necessary to enable legal enforcement of the new
codes within the jurisdiction. The design community, contractors, developers, manufacturers, material suppliers
and the publishers of standards all depend on statewide uniformity in the codes that impact their businesses.
More importantly the citizens of Tukwila deserve to know that the built environment that they live, work and
play in are designed with the latest health, fire and life safety measures.
The model codes are revised in a code change process that takes place on a three-year cycle. In the listed
code change year, the State Building Code Council reviews the codes and adds State amendments that reflect
conditions that are unique to Washington State.
FINANCIAL IMPACT
N/A [2018 code editions have been purchased and the major training has been obtained pre-Covid]
RECOMMENDATION
The Council is being asked to approve and forward the ordinance for the adoption of 2018 State Building code
to the January 25, 2021 Special meeting consent agenda for adoption.

High Level Code Changes and Appendices
2018 International Building Code
The occupant load factor for business uses has been revised to one occupant per 150 square
feet (was 100 sq ft).
Engineered wood / Mass Timber
Building codes are evolving to support new technological developments for one of our oldest
building materials in modern times, structural wood has been largely confined to residential and
low-rise commercial construction, despite its proven structural performance and ability to
endure seismic and wind events.
Recent innovations and subsequent code changes are expanding the use of structural wood
beyond these established sectors. Techniques utilize engineered wood products such as cross-
laminated timber (CLT), nail-laminated timber (NLT), dowel-laminated timber (DLT), and
structural glued-laminated timber (glulam).
These “mass timber” products have great structural capability and inherent fire resistance, and
interest in mid- and even high-rise wood buildings that incorporate these technologies. Recent
code changes reflect the growing body of research that validates these systems for structural
performance and for contribution to life safety during extreme events, such as fires, hurricanes,
and earthquakes.
Five-foot tall wood trusses requiring permanent bracing must have a periodic special inspection
to verify that the required bracing has been installed.
Appendix E (Accessibility and ICC/ANSI A117.1-2009)
2018 International Residential Code (IRC)
The townhouse separation provisions now include options for using two separate fire-resistant-
rated walls or a common wall.
The exemption for interconnection of smoke alarms in existing areas has been deleted (all
smoke alarms are now required to be interconnected)
Appendix F (Radon Control Methods)
Appendix Q (Tiny Homes)
99
Uniform Plumbing Code
Appendix A (Sizing - Water Supply System)
Appendix B (Notes - Combination Waste and Vent System)
Appendix I (Installation Standard for PEX Tubing System)
IBC and IRC
The exemption for a one-story detached accessory structures used as tool and storage sheds,
playhouses and similar uses, do not require a permit provided the floor area does not exceed
120 square feet (was 200 in the IRC), and such structure is outside of and entirely separated, as
prescribed by Code, from any existing building on the premises.
Reason: Consistency between the 2018 International Residential Code (200 square foot)
and the 2018 International Building Code (120 square foot)
Fences not over 6 feet high (was 7-foot in both IBC and IRC)
Reason: Climate. It rains in our area for days soaking the soil followed by high winds. A 7-
foot fence with a foot of lattice would cause more damage to fences.
TMC Chapter 16.05 Deleted [CHAPTER 16.05 5-STORY TYPE V-A BUILDINGS]
Reason: As stated in 16.05.010 Purpose of Chapter. The purpose of TMC Chapter 16.05
is to authorize the construction of 5-story Type V-A buildings as an approved alternate
design and construction method under Section 104.11 of the International Building
Code, 2009 Edition, and to set forth the criteria and standards which must be met prior
to a building permit being issued for a 5-story Type V-A building.
The chapter became obsolete when the International Building Code 2009 edition was
replaced by the adoption of the International Building Code 2012 edition. The current
2018 edition of the International Building Code to addresses 5-story Type V-A buildings
100
