On March 25, 2022, Governor Inslee signed the Clean Buildings expansion bill into law. The expansion applies to buildings 20,000 square feet or larger, adding a new second tier that includes multifamily buildings. The first phase of this law is not a performance standard. It will require reporting on benchmarking, energy management plans and operations and maintenance programs for Tier 2 buildings. Compliance and reporting for this new tier is July 1, 2027.
