In 2023 the state established retainage and interest requirements for contractors and subcontractors in private construction projects, excluding single-family residential construction with less than 12 units.
An owner, contractor, or subcontractor may withhold as retainage up to 5 percent of the contract price of the work completed for private construction projects. Partial payment is not acceptance or approval of some of the work or a waiver of defects in the work. The owner, contractor, or subcontractor must pay interest at the rate of 1 percent per month on the final payment due the contractor or subcontractor. The interest commences 30 days after the contractor or subcontractor completes and the owner accepts the work under the contract, and it runs until final payment is tendered to the contractor or subcontractor.
When the contractor or subcontractor considers the work that the contractor or subcontractor is contracted to perform to be complete, the contractor or subcontractor must notify the party to whom the contractor or subcontractor is responsible for performing the construction work under the contract. The party must, within 15 days after receiving the notice, either accept the work or notify the contractor or subcontractor of work yet to be performed under the contract or subcontract. If the party does not accept the work or does not notify the contractor or subcontractor of work yet to be performed, the interest commences 30 days after the end of the 15-day period.
A contractor may provide notice to an owner or upper-tier contractor for release of retainage due to a subcontractor whose work is complete. If an owner or upper-tier contractor does not accept the subcontractor's work or does not notify the contractor of work yet to be performed by the subcontractor within 15 days after receiving the notice, the interest required commences 30 days after the end of the 15-day period. A contractor's obligation to pay interest to a subcontractor does not begin until the contractor has received payment for the subcontractor's retainage provided that the contractor has submitted the subcontractor's retainage request to the owner or upper-tier contractor within 30 days after receipt from the subcontractor.
In lieu of retainage, a subcontractor or contractor may tender, and a contractor or owner must accept, a retainage bond, which must meet certain requirements. If an owner accepts a bond in lieu of retained funds, the contractor must accept like bonds from any subcontractors or suppliers from which the contractor has retained funds.
