Every three years new model codes are published. The Council, with the assistance of their Technical Advisory Groups (TAGs), reviews and adopts the new editions. In addition, the TAGs also review any changes proposed to these new editions, or to the pre-existing state amendments.
For review, the 2021 codes are broken into two groups. Group 1 includes the International Building Code, International Fire Code, International Wildland Urban Interface Code and the Washington State Energy Code-Commercial. Group 2 includes the International Existing Building Code, International Building Code Structural Provisions, International Residential Code, International Mechanical Code, International Fuel Gas Code, NFPA 58, NFPA 54 and the Washington State Energy Code-Residential. Group 1 codes are evaluated in the first year of review, Group 2 codes in the second year, and the codes are adopted effective in the following year.
Any proposal to change the state building code must be received by the date set by the Council. Group 1 codes proposals for the 2021 codes can be received on April 1, 2021 with a deadline of June 1, 2021 at 5:00 p.m.
