Establishing fenestration certification requirements for certain public works contracts.

HB 2390 requires contractors working on large public projects involving windows, skylights, or similar fenestration products to meet specific certification standards. It applies to new construction projects over $25 million and other work over $5 million, starting January 1, 2028. Contractors must hold a national glazing contractor certification and employ certified technicians, with a requirement for at least 25% of fenestration workers to be certified by 2029. Documentation of compliance must be submitted with bids and is a condition for contract award and payment. This bill directly affects contractors bidding on qualifying public works projects in Washington state.
