Washington State adopted the 2015 edition of the International Building Code (IBC) on July 1, 2016 and the City of Seattle is scheduled to adopt the changes in January 2017. Both will still reference the 2009 edition of the ICC A117.1.
The State of Oregon has determined that the 2015 IBC serves as an effective Statewide Alternate Method to the 2014 Oregon Structural Specialty Code (OSSC). Publication can be found at: https://www.oregon.gov/bcd/codes-stand/Documents/sam-16-01-2015ibc.pdf
