On March 25, 2022, Governor Inslee signed the Clean Buildings expansion bill into law. The expansion applies to buildings between 20,000-50,000 square feet, 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.

Reporting for this new tier is expected to begin July 1, 2027. The expansion bill also included an incentive program with an additional $150 million available for Tier 2 buildings at a rate of .30 cents per square foot. The new law requires Commerce to complete rulemaking by December 1, 2023.


Commerce will host a series of workshops to establish rules, reporting requirements, and the incentive program for Tier 2 buildings. The kick-off meeting will be a pre-rulemaking webinar, introducing the Clean Buildings Expansion and rulemaking basics.
