Prompt payment

California prompt payment act and retainage rules

California spreads its prompt payment rules across the Public Contract Code, the Civil Code, and the Business and Professions Code. Public work has a 5 percent retention cap, and since January 1, 2026 most private work does too.

In California, public owners must pay undisputed progress payments within 30 days or owe interest, and private owners must pay within 30 days of a payment demand or owe a 2 percent per month penalty. Primes pay subs within 7 days of receiving a progress payment. Retention (California's word for retainage) is capped at 5 percent on public works and, for private contracts entered on or after January 1, 2026, on most private works too. Public owners release retention within 60 days after completion; private owners within 45 days.

Public projects: payment deadlines

State agencies must pay an undisputed, properly submitted progress payment request within 30 days or pay interest at the legal rate in Code of Civil Procedure 685.010(a), which is 10 percent per year. Local agencies (cities, counties, districts) have the same 30 day rule under PCC 20104.50, and the contract must include that article or a summary of it. Under both statutes, an improper request must be sent back within 7 days with written reasons. If the agency takes longer than 7 days to return it, the extra days come off its 30 day window. Note that for local agencies, a "progress payment" excludes the retention portion of final payment, which follows PCC 7107 instead.

On state jobs, PCC 10262 requires the prime to pay subs within 7 days of each progress payment. For other work, B&P 7108.5 sets the same 7 day rule, allows withholding of up to 150 percent of a good-faith disputed amount, and adds a 2 percent per month penalty payable to the sub. It is also grounds for discipline by the Contractors State License Board.

Public retention: 5 percent cap and 60 day release

PCC 7201 caps retention at 5 percent of each payment and 5 percent of the total contract price for public works contracts entered on or after January 1, 2012, and the same cap flows down every tier. A sub cannot be held at a higher rate than the prime. Exceptions: a sub that was told at bid time that bonds would be required and then fails to furnish them, and specific projects that the awarding body finds "substantially complex" before bid, with the higher rate disclosed in the bid documents. Nobody can be required to waive the section.

PCC 7107 requires the public entity to release retention within 60 days after completion (defined as beneficial use and cessation of labor, acceptance, a 100 day stoppage, or a 30 day stoppage with a recorded notice). One exception: a state agency holding no more than 125 percent of the estimated value of the remaining work gets 90 days to release undisputed retention. The prime then has 7 days to pay each sub its share. Late retention costs 2 percent per month, attempted waivers are void, and the prevailing party gets attorney's fees. Under PCC 22300, public contracts must let the contractor substitute securities for retention or have retention paid into escrow, with the interest going to the contractor. A contractor that elects to earn interest on retention must, on request, give the same option to any sub performing more than 5 percent of its total bid.

Private projects: Civil Code 8800 to 8818

Unless otherwise agreed in writing, a private owner pays an undisputed progress payment within 30 days after the contractor gives notice demanding payment under the contract. The penalty for missing it is 2 percent per month on the amount wrongfully withheld, and the owner may withhold no more than 150 percent of a good-faith disputed amount. The words "unless otherwise agreed in writing" matter: a contract can set a different schedule, so read the payment article before you sign.

  • Retention release: the owner pays retention within 45 days after completion of the work of improvement (Civil Code 8812). The prime pays each sub its share within 10 days after receiving it (Civil Code 8814).
  • Late retention: 2 percent per month plus attorney's fees to the prevailing party (Civil Code 8818).
  • New 5 percent cap: for private contracts entered on or after January 1, 2026, Civil Code 8811 caps retention at 5 percent of each payment and of the contract price, at every tier.
  • Cap exceptions: a sub that fails to furnish bonds it was told about at bid time, and residential projects that are not mixed-use and do not exceed four stories.

The statutes above set timing after the prime receives money. They do not decide whether a pay-if-paid clause in a subcontract can shift the risk of owner nonpayment to the sub; that question turns on contract law and case law, so have counsel review the clause. See pay-if-paid vs pay-when-paid clauses explained.
