King County buildings must meet the Washington State Energy Code under RCW 19.27A, one of the strictest in the nation; the county's Strategic Climate Action Plan also drives green-building incentives toward carbon neutrality by 2050.
All new construction and major remodels in King County must comply with the Washington State Energy Code (WSEC), adopted statewide under RCW 19.27A and updated on a three-year cycle by the State Building Code Council. The 2021 WSEC restricts most natural-gas space and water heating in new commercial and large multifamily projects, pushing electrification. King County's Strategic Climate Action Plan (SCAP, 2020 update) targets carbon neutrality by 2050, and the King County Green Building Program offers incentives, technical assistance, and LEED/Built Green tracking for unincorporated projects. Local Services Permitting reviews energy-code compliance alongside structural plan review.
Failing energy-code compliance is a building-code violation under RCW 19.27A, with corrections required before final permit approval and certificate of occupancy issuance.
