Get Ready for the 2015 Building Codes
The City is updating the codes we use to review and inspect your projects. We plan to use the 2015 Seattle codes to review new building permit applications and plans submitted after January 1, 2017. Seattle’s codes are based on model codes published by the International Code Council, the International Association of Plumbing and Mechanical Officials, and the State of Washington’s adoption of codes.
