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.
DPD is on schedule for new editions of seven codes to take effect next summer or fall. Public review of the 2012 Seattle building, residential, existing building, mechanical, fuel gas, energy and plumbing codes is almost complete. We expect the ordinances adopting these codes to take effect this summer, followed by a 60-day period during which applicants can use either the 2009 or 2012 codes.
