We update the Seattle Building, Existing Building, Residential, Plumbing, Energy, Mechanical, and Fuel Gas codes every three years. We review the model codes (International and State codes), that are the base of our codes, and create amendments to make the Seattle codes reflect the unique needs of our city.
We are reviewing what will become the 2015 suite of adopted codes. We are posting drafts of the amended codes on the Project Documents page as we make them available for public review. Our Get Involved page provides information on how you can submit comments on these drafts.
The State of Washington is also reviewing the International Building Codes for statewide adoption.
By reviewing, amending, and adopting the model codes, we help ensure that Seattle’s built environment reflects the latest in design, technologies, and safety standards
We expect the 2015 Seattle codes to take effect in January 2017.
