SUMMARY OF ACTION:
Every three years the International Code Council Updates the international codes. These codes include the building

Washington reviews the codes and adopts them with their own amendments. Pursuant to state law, all cities within the
state must adopt the codes and amendments at the local level, concurrently with the state.
These codes were to be adopted statewide on July 1, 2020, but because of delays created by COVID-19, the State of
Washington decided to put off the adoption of the codes until February 1, 2021. In addition to the International codes,
updated versions of other codes such as the Uniform Plumbing Code and the Washington State Energy Code are also

The purpose of this code adoption is to remain in compliance with RCW 19.27.031 that requires the city to adopt these
