State Building Code Council (SBCC)

The State Building Code Council (SBCC) was created to provide independent analysis and objective advice to the legislature and the Governor’s Office on state building code issues. The SBCC establishes the minimum building (mechanical, fire, plumbing, and energy code) requirements necessary to promote health, safety, and welfare to the people of the state of Washington by reviewing, developing, and adopting the state building code.
