Bill > HB3166

This bill establishes rules to govern construction contracts, defining terms like "construction contract" as agreements for various building and infrastructure projects for non-governmental purposes, and "owner" as anyone with such a contract. It declares certain contract provisions void as against public policy, including those that allow withholding excessive payments, prevent suspending work for non-payment, require continued work without payment, mandate extra work without prior agreement on cost, force waiver of rights for undisputed payments, or allow adverse actions like termination or withholding payment without proper written notice and an opportunity to cure. The bill also sets payment timelines, requiring owners to pay contractors within 40 days of receiving an invoice or pay application, and contractors to pay subcontractors within seven days of receiving payment from the owner for the subcontractor's work, with specific notice requirements if payment is withheld due to non-compliant work. These provisions apply to all parties in the construction contract chain, regardless of their tier, but exclude owner-occupied residential properties of four units or less and only apply to contracts entered into after August 28, 2026.
