The 2009 Seattle building, residential, mechanical, fuel gas, and existing building codes will take effect on September 23, 2010. The effective date is followed by a 60-day period during which applicants may choose to use either the 2006 or 2009 codes. The last date on which DPD will accept applications using the 2006 codes will be November 22, 2010.
We don’t yet know when the code books will be available. In the meantime, the legislation adopting the codes is posted at www.seattle.gov/DPD/Codes/Technical_Codes/Overview/default.asp. If you’d like to be notified when the codes are available, subscribe to our technical codes mailing list at www.seattle.gov/DPD/Codes/Technical_Codes/
The 2009 Seattle Energy Code is on a different schedule, though we hope it will catch up to the other codes (with a shorter “grace period”). See related article.
