Finding—Intent—2015 c 11: "The legislature finds that the state building code council adopted by rule changes to the climate zones used in the building codes due to modifications in the 2012 international energy conservation code (IECC). The legislature intends to update the statutes to be more reflective of the national standards." [2015 c 11 § 1.]
Intent—Finding—2003 c 291:
"(1) The intent of the adoption of the International Building Code by the legislature is to remain consistent with state laws regulating construction, including electrical, plumbing, and energy codes established in chapters 19.27
, 19.27A, and 19.28
RCW. The International Building Code references the International Residential Code for provisions related to the construction of single and multiple-family dwellings. No portion of the International Residential Code shall supersede or take precedent over provisions in chapter 19.28
RCW, regulating the electrical code; nor provisions in RCW 19.27.031
(4), regulating the plumbing code; nor provisions in chapter 19.27A
RCW, regulating the energy code.
(2) It is in the state's interest and consistent with the state building code act to have in effect provisions regulating the construction of single and multiple-family residences. It is the legislative intent that the state building code council adopt the International Residential Code through rule making granted in RCW 19.27.074
, consistent with state law regulating construction for electrical, plumbing, and energy codes, and other state and federal laws regulating single and multiple-family construction.
(3) In accordance with RCW 19.27.020
, the state building code council shall promote fire and life safety in buildings consistent with accepted standards. In adopting the codes for the state of Washington, the state building code council shall consider provisions related to firefighter safety published by nationally recognized organizations. The state building code council shall review all nationally recognized codes as set forth in RCW 19.27.074
(4) The legislature finds that building codes are an integral component of affordable housing. In accordance with this finding, the state building code council shall consider and review building code provisions related to improving affordable housing." [2003 c 291 § 1.]
