Spokane construction must meet the Washington State Energy Code under RCW 19.27A and the latest Washington Energy Code adopted through SMC Chapter 17F, with City Climate Action Plan goals encouraging electrification and high-performance building beyond minimum code.
Washington's State Energy Code, among the most stringent in the U.S., applies to all new and substantially altered buildings in Spokane through SMC Chapter 17F. The 2021 code cycle pushed commercial buildings toward heat pump space and water heating, increased envelope insulation, and tightened airtightness and ventilation. Spokane's 2021 Sustainability Action Plan and Climate Action Plan set city-level goals for net-zero emissions and encourage but do not require all-electric construction. Permit applicants typically submit COMcheck or REScheck reports proving compliance, and Spokane Building Services inspects before approving final occupancy.
Failing energy code review can produce permit revisions, mandatory blower door or duct testing, and certificate-of-occupancy holds until COMcheck or REScheck compliance is verified.
