2015 International Building Code
  • The International Code Council promulgates the International Codes that form the basis for building codes in Washington State and the City of Edmonds.  Visit their site to explore the national code development process.

  • In Washington the State Building Code Council is charged with the adoption and amendment of the International Codes.  The council was created by the State Legislature in 1974 and given authority from RCW 19.27. 

  • A good source of code books and other code related publications is the Washington Association of Building Officials Bookstore.  You can also check the WABO website to check for training opportunities, resources and to see what is happening within the state building code world. 

  • The State Energy Codes.  A very good source of information on energy codes with some very useful publications is the WSU Energy Extension.
