ACTION ITEM                            Date of Meeting     February 27, 2018 
DATE:     February 20, 2018 
TO:        Executive Director Stephen P. Metruck 
FROM:    KC Ellis, Sr. Manager, Airport Building Department 
Jeffrey Brown, Director, Facilities & Capital Programs 
SUBJECT:  Adoption of Resolution 3745 to adopt the 2015 Building Codes, Amendments and
Permit Fee Schedule 

ACTION REQUESTED 
Request adoption of Resolution No. 3745: a resolution of the Port Commission of the Port of
Seattle adopting the 2015 editions of the International Code Council, Building, Mechanical, Fire
Codes and Fuel Gas Code, the 2015 Edition of the Uniform Plumbing Code, and 2015
Washington State Energy Code and the editorial changes made to the State Building Code by
the Washington State Legislature; repealing certain sections of the Airport Building Code;
adopting new sections of the Airport Building Code and repealing Resolution 3527, as amended. 
EXECUTIVE SUMMARY 
The building industry, contractors, designers, developers, and project managers depend on
statewide uniformity in the codes that impact their businesses. Projects at the SeaTac airport
are built to the 2015 state code. The adoption of this resolution will update the administrative
portions of the building code to fit with the airport environment. In addition, several building
code amendments will help streamline the permit process.
State Building Code does not include specifications and/or guidelines on transgender or unisex
bathrooms that would allow us to include in an update to our codes (it does allow for a
minimum number of men's, women's and family restrooms). The Port, and any other private or
public institution, cannot create building code less than what is allowed in State Building Code.
The Port can, however, adopt a policy stating our intention to construct/house transgender
restrooms at our facilities over and above the minimum number of men's, women's and family
restrooms required by State Building Code. 
JUSTIFICATION 
The State Building Code Council was created to advise the legislature on building code issues
and develop building codes used in the State of Washington. In the course of development of
the State Building Code (otherwise known as Chapter 19.27 RCW), the Council holds public
hearings, considers proposed state amendments, and adopts the international model codes

performance for fire, health and life safety codes. The amendments better protect the
public health, welfare and safety of the unique airport environment.
