Codes adopted

The State Building Code is in effect in every county and city in Washington, and its minimum performance standards may not be diminished locally. A local amendment that affects single-family or multifamily residential buildings is not effective unless the State Building Code Council approves it; amendments to non-residential provisions carry no such approval requirement.

  THE 2021 IBC, NAMED, AND TIED TO THE STATE'S OWN ADOPTION. SMC 16.05.070: "The 2021 Edition of the International Building Code, as adopted by the State Building Code Council in Chapter 51-50 WAC, as published by the International Code Council, including Appendix Chapter E (Accessibility), ICC A117.1-2017 (Accessible Standards), and Appendix Chapter H (Signs), excluding Chapter 1, Administration, is hereby adopted by the City of Sammamish".

  THE 2021 IRC, WITH TINY HOUSES IN. SMC 16.05.080: "The 2021 Edition of the International Residential Code, as adopted by the State Building Code Council in Chapter 51-51 WAC, as published by the International Code Council, including Appendix Q, Tiny Houses, and excluding Chapters 1, 11 and 25 through 43, is hereby adopted by the City of Sammamish". Appendix Q IS adopted here, as in Camas and Yakima - and NOT as in Marysville, which excludes IRC Appendices AF, AQ and AU.

• ADMINISTRATION COMES FROM THE CITY, NOT THE MODEL CODE. Both adoptions exclude Chapter 1, Administration; SMC Chapter 16.20 is the city's own Construction Administrative Code and supplies permits, inspections, fees and enforcement in its place.
• A SCOPED ROLLING ADOPTION FOR ONE STATE CHAPTER ONLY. SMC 16.05.180 adopts by reference, "as presently existing and as may be subsequently amended", the single chapter "Chapter 51-19 WAC, Washington State Historic Building Code". That rolling language does NOT extend to the building or residential codes.
• Other codes named in Chapter 16.05: the mechanical code, NFPA 54 National Fuel Gas Code, NFPA 58 Liquefied Petroleum Gas Code, the International Fuel Gas Code, the International Fire Code, the Uniform Plumbing Code, the Washington State Energy Code, the Washington Cities Electrical Code, the 2021 International Existing Building Code and the 2021 International Swimming Pool and Spa Code.
• RCW 19.27 - the Washington State Building Code applies statewide.
