The State Building Code Council has adopted the 2009 editions of the codes below, with the noted amendments. These codes will go into effect July 1, 2010, with the exception of the Washington State Energy Code.  Implementation of the WSEC has been postponed until October 29, 2010. 

The Washington State Ventilation and Indoor Air Quality Code has been repealed, as has the Washington State Historic Building Code. Provisions formerly found in the VIAQ are now located in the IRC, the IMC and the IBC as appropriate. The Historic Building Code has been replaced by the International Existing Buildings Code, as adopted and amended by WAC 51-50-48
