The Clean Buildings Performance Standard is mandatory for Tier 2 covered buildings located in the state of Washington. On March 25, 2022, Governor Inslee signed the Clean Buildings expansion bill (PDF) into law to include Tier 2 covered buildings. A Tier 2 building is a building where the sum of multifamily residential, nonresidential, hotel, motel and dormitory floor areas exceeds 20,000 gross square feet, but does not exceed 50,000 gross square feet, excluding the parking garage area. Tier 2 covered buildings also include multifamily residential buildings where floor areas are equal to or exceed 50,000 gross square feet, excluding the parking garage area.
- Federal buildings and buildings owned by federally recognized tribes are not required to comply with the standard.
- For Tier 1 covered buildings content, see the Tier 1 compliance webpage.
Tier 2 compliance requirements
- Benchmarking by measuring and tracking energy use in a building over time.
- Implementing an operations and maintenance program.

If a Tier 2 covered building meets one of the exemption criteria in RCW 19.27A.210(7)(c) or Section Y4.1 of the standard, building owners can apply for an exemption on July 1, 2025, two years prior to the scheduled compliance date and submitted to Commerce no later than 180 days prior to the compliance date.
Exemption certificates for approved buildings are only valid for the current compliance review cycle. Within six months before the compliance date, building owners who have received exemption approval must certify that the building still meets the eligibility qualifications for the exemption and that there have been no material changes to qualifying conditions. Commerce will provide a one-page declaration for exempted building owners to sign.
A list of acceptable documents can be found in Clean Buildings Performance Standard, Annex Y6.7.
