On California public works projects worth more than $25,000, the direct contractor has to post a payment bond in California equal to the full contract price before starting work. If the contractor doesn’t pay a subcontractor, supplier, or laborer, the surety company that issued the bond covers the debt. Collecting on that bond depends on two things most claimants underestimate: sending a preliminary notice at the start of the job, and filing suit within the statutory window.
Who Can Collect on the Bond
The bond covers anyone who provided labor, materials, equipment, or services authorized by the direct contractor, a subcontractor, an architect, a project manager, or another person in charge of part of the work. Laborers are specifically included. It also covers unemployment insurance contributions and wage withholdings owed to the Employment Development Department in connection with the project.1California Legislative Information. California Code Civil Code 9554 – Payment Bond
Two limits matter. First, the direct contractor cannot claim against its own bond.2California Legislative Information. California Code Civil Code CIV 9100 Second, only claimants whose work reached the direct contractor, either directly or through a chain of subcontracts, can recover. A supplier with no link to that chain has no standing.3California Legislative Information. California Code Civil Code CIV 9566
When a Payment Bond Has to Exist
Local and Other Non-State Public Works
For contracts awarded by cities, counties, school districts, and other non-state public entities, a payment bond is required whenever the contract exceeds $25,000. The direct contractor has to deliver the bond to the awarding entity before any work starts, and the awarding entity must say in its bid solicitation that a bond is required. Design professionals are not treated as direct contractors under this section and don’t have to furnish a bond.4California Legislative Information. California Civil Code 9550
State Agency Contracts
State agency contracts follow a parallel rule under the Public Contract Code. The same $25,000 threshold and 100% bond amount apply, but the bond gets filed with the state officer or entity that awarded the contract.5California Legislative Information. California Public Contract Code PCC 7103
Federal Projects on California Soil
Federal projects sit outside state law. Under the Miller Act, a payment bond is required on any federal contract exceeding $100,000.6Office of the Law Revision Counsel. 40 USC 3131 – Bonds of Contractors of Public Buildings or Works First-tier subcontractors and suppliers can sue on the bond without giving prior notice to the prime. Second-tier parties have to send written notice to the prime within 90 days of their last day of work or delivery. Any lawsuit must be filed no earlier than 90 days and no later than one year after the last labor or materials were furnished.7U.S. General Services Administration. Miller Act: How Payment Bonds Protect Subcontractors and Suppliers
Private Projects
California does not require payment bonds on private construction. Owners and generals sometimes require them anyway on large developments, but when a private payment bond exists, its terms are governed by the bond’s own language and the underlying contract, not the public works statutes.
The License Bond Is Not a Payment Bond
Every licensed California contractor carries a $25,000 contractor’s bond as a condition of holding an active license. That bond compensates consumers harmed by defective work or license-law violations and covers unpaid employee wages. It is not project-specific and does not protect subcontractors or suppliers on a particular job.8California Legislative Information. California Business and Professions Code 7071.6 The matching $25,000 figure fuels the confusion.
Send the Preliminary Notice Before Anything Goes Wrong
Before you can assert a claim against a payment bond, you have to give preliminary notice to the project owner, the direct contractor, and the construction lender (if any). This is a statutory prerequisite, not a formality. Without it, the bond claim is invalid, and the notice has to go out proactively, before any payment dispute exists.9California Legislative Information. California Code Civil Code 8200 – Preliminary Notice
Two exemptions apply. Laborers don’t have to give preliminary notice at all. A claimant with a direct contract with the project owner only has to notify the construction lender, if one exists.9California Legislative Information. California Code Civil Code 8200 – Preliminary Notice
This is where most claims fall apart. A subcontractor or supplier who skipped the notice finds out only when they try to file a claim months later. Sending the notice at the start of every job, even when payment looks routine, is the cheapest step in the whole process and the one that protects everything else.
Filing the Claim With the Surety
If preliminary notice was properly given, you enforce the claim by following the notice procedures set out in the Civil Code. If you never sent preliminary notice, the statute provides a narrow fallback: you can still enforce a claim by sending written notice to the surety and the bond principal within 15 days after a notice of completion is recorded. If no notice of completion was recorded, that window stretches to 75 days after the work of improvement is actually completed.10California Legislative Information. California Code Civil Code 9560 – Payment Bond
The written notice to the surety should state the amount owed, describe the work performed or materials supplied, and identify the project. The surety then investigates by reviewing documentation and communicating with the claimant and the contractor. If it finds the claim valid, it pays the claimant directly.
The Deadline to Sue
You can file a lawsuit to enforce the bond any time after you stop providing work, but no later than six months after the period in which a stop payment notice could have been given. Miss that window and the claim is extinguished regardless of its merit. Because the stop-payment-notice period depends on when a notice of completion or cessation is recorded, tracking those recordings is part of protecting the deadline.
You can sue the surety on the payment bond whether or not you also filed a stop payment notice with the public entity. The action against the surety proceeds independently, without first suing the public entity or its officers.11California Legislative Information. California Code Civil Code CIV 9564
If you win, the surety pays the claim amount plus a reasonable attorney’s fee as fixed by the court. That fee-shifting provision is what gives the bond real teeth for a small subcontractor.1California Legislative Information. California Code Civil Code 9554 – Payment Bond
The Stop Payment Notice as a Second Track
California gives public works claimants a second tool alongside the bond: the stop payment notice. Served on the public entity’s disbursing officer, it forces the entity to set aside enough contract funds to cover the disputed amount. The stop payment notice and the bond claim are independent remedies. You can pursue one, the other, or both.
The practical value is timing. A stop payment notice freezes money before it flows to the general contractor, while the bond claim pursues the surety. Used together, they apply pressure from two directions at once.
How Sureties Defeat Claims
The defenses that actually end claims cluster around a few themes.
The most common is missed preliminary notice. Because the notice is a statutory prerequisite, its absence kills the claim before anyone looks at the merits.9California Legislative Information. California Code Civil Code 8200 – Preliminary Notice Claimants relying on the Section 9560 fallback have to prove they hit the 15-day or 75-day deadline.10California Legislative Information. California Code Civil Code 9560 – Payment Bond
Scope arguments are next. Only work provided pursuant to the public works contract qualifies for bond recovery, so a surety may argue the claimed labor or materials fell outside the contract.3California Legislative Information. California Code Civil Code CIV 9566 Change orders and extras complicate this, so written authorizations matter.
Standing arguments knock out remote parties. A claimant who cannot show its work reached the direct contractor, directly or through a subcontract chain, has no right to recover.3California Legislative Information. California Code Civil Code CIV 9566
Finally, contractors sometimes defend by asserting defective work or nonconforming materials. That defense lives or dies on documentation: inspection reports, written complaints raised during the project, and evidence that the claimant had a chance to cure. Bare assertions of poor quality rarely carry the day.
Payment Bond vs. Performance Bond
Payment bonds and performance bonds usually appear together on public works, but they protect different people. A payment bond guarantees that subcontractors and suppliers get paid. A performance bond guarantees the project owner that the work will be completed under the contract. If a contractor defaults on a performance bond, the surety may finance the original contractor to finish, hire a replacement, or pay the owner the cost to complete. Either way, the contractor remains liable to reimburse the surety. For a subcontractor, the payment bond is the one that matters. The performance bond protects the owner.
