If you’re a subcontractor, supplier, or equipment lessor on a California public works job and you don’t have a contract directly with the prime contractor, the California preliminary notice for public works is the form you serve to keep your right to get paid through a stop payment notice or the project’s payment bond. You can’t record a mechanics lien against government property, so the bond and the stop payment notice are the real recovery tools, and this notice is what unlocks them. Get the content, the recipients, the method, and the timing right, and you preserve every remedy the Civil Code gives you.
Who Has to Serve It
Under California Civil Code Section 9300, any claimant who wants the option of filing a stop payment notice or pursuing a payment bond claim must first serve a preliminary notice on the public entity and the direct contractor.1Justia. California Code Civil Code 9300-9306 – Preliminary Notice In practice that means second-tier subcontractors, lower-tier suppliers, equipment rental companies down the chain, and anyone else without a direct contract with the prime.
Two groups are exempt. Laborers don’t need to serve a preliminary notice to protect their wage claims. And claimants with a direct contractual relationship with the prime contractor are exempt as well, which covers first-tier subcontractors and material suppliers who contracted directly with the prime.1Justia. California Code Civil Code 9300-9306 – Preliminary Notice If you’re in that category, you can skip the notice and still pursue bond claims and stop payment notices later. Everyone else needs to serve it or lose those remedies.
The prime contractor itself doesn’t serve this notice. The statute is written for claimants who may later need to recover payment, and the prime is paid directly by the public entity.
What the Notice Must Contain
Two statutes drive the content. Section 8102 sets the baseline information required in any notice under California’s construction payment laws, and Section 9303 adds items specific to public works.2California Legislative Information. California Code Civil Code 8102 – Notice Requirements3California Legislative Information. California Code Civil Code 9303 – Preliminary Notice Your notice needs:
- Your full legal business name, address, and relationship to the other parties (subcontractor, material supplier, equipment lessor, and so on).
- The direct contractor’s exact legal name and address. Pull it from your contract or the project documents.
- The public entity’s name and address, spelled out precisely. Use “City of Sacramento Department of Public Works,” not “the city.” A wrong agency name creates problems later.
- A description of the project site. A street address works. A sufficient legal description will carry the notice even if the street address is wrong or missing.
- The name of the person to or for whom you are providing work. Usually the subcontractor or contractor who hired you.
- A plain description of your work: “electrical wiring and panel installation,” “concrete supply,” “HVAC ductwork.” No line items needed.
- An estimate of the total price of your work, meaning the full anticipated value, not just what you’ve furnished so far. Give a reasonable estimate even if the final number may shift.
Section 8102 also lists the owner’s name and address and the construction lender’s name and address as standard items, but on a public works job there is no private owner or construction lender. The public entity fills both roles. List the public entity information in those fields or mark them not applicable.
Section 8102(b) says a notice isn’t invalid because of a variance from the statutory requirements as long as it substantially informs the recipient of the required information.2California Legislative Information. California Code Civil Code 8102 – Notice Requirements A misspelled street name probably won’t matter if the project is otherwise identifiable. Getting the public entity’s legal name wrong or omitting the price estimate is a much bigger risk. Substantial compliance is a safety net, not a license to be sloppy. The claimant arguing substantial compliance in court has already spent money on lawyers.
California does not publish an official government preliminary notice form. Construction notice services, legal stationers, and industry groups offer templates built around Sections 8102 and 9303, and some county law libraries make samples available. Whatever template you use, confirm it includes every field above. Many off-the-shelf forms are built for private works and omit the public-works-specific items from Section 9303.
How and Where to Serve It
You serve the completed notice on two parties: the public entity that awarded the contract, and the direct contractor to whom you provide work.1Justia. California Code Civil Code 9300-9306 – Preliminary Notice Both. Sending it to only one doesn’t satisfy the requirement.
Civil Code Sections 8106 and 8110 together set the acceptable delivery methods:4California Legislative Information. California Code Civil Code 8106 – Notice Delivery Methods5California Legislative Information. California Code Civil Code 8110 – Notice by Mail
- Personal delivery. Notice is complete when delivered.
- Registered or certified mail. The standard approach. Notice is complete when deposited in the mail.
- Express mail or overnight delivery by an express service carrier such as FedEx or UPS Next Day. Notice is complete when deposited with the carrier.
- Substitute service: leaving the notice and mailing a copy as described in Code of Civil Procedure Section 415.20. Notice is complete five days after mailing.
Section 8116 confirms that mailed notice is legally “given” the moment you deposit it, not when the recipient opens it.6Justia. California Code Civil Code 8100-8118 – Notice That matters for the 20-day rule below. Use a method that generates a receipt. Certified mail return receipts and overnight carrier tracking confirmations are what you’ll need if service is ever challenged.
The 20-Day Timing Rule
Section 9304 controls how much of your work the notice protects. Serve within 20 days of first furnishing labor or materials and you’re covered for everything from day one forward. Serve later and your stop payment notice or bond claim can only reach work provided during the 20 days before service, plus all work after service.7California Legislative Information. California Code Civil Code 9304 – Preliminary Notice
This is not a hard deadline that kills the notice. A late notice is still valid; it just covers less of your work. Say you start delivering materials on March 1 and serve the notice on April 15. Your bond claim or stop payment notice can only reach materials delivered from March 26 onward (the 20 days before April 15) and anything after. Everything before March 26 is unprotected. On a long project, even a few days of delay can mean losing coverage on significant early deliveries. Serve early.
Proof You Served It
No California statute specifically requires a proof of service affidavit after serving the preliminary notice. As a practical matter, though, you need to be able to prove service if a payment dispute reaches litigation. Keep a file containing a copy of the completed notice as served, the certified mail receipt or overnight tracking confirmation, and the return receipt (green card) once it comes back. Note the date you mailed or delivered the notice, the address you used, and the person or office that received it.
Some construction notice services and attorneys prepare a formal proof of service declaration as part of their standard process. It’s not legally mandated, but a declaration signed and dated at the time of service is strong evidence. Reconstructing service details months later during a bond claim is where cases fall apart.
What the Notice Preserves
Serving the preliminary notice doesn’t recover any money by itself. It preserves two enforcement tools if you don’t get paid.
The first is a stop payment notice, which directs the public entity to withhold funds from the direct contractor in the amount of your claim. It must be signed, verified, and include a description of your work and an estimate of the amount owed through the date of the notice. It must be served before the later of 30 days after a notice of completion or cessation is recorded, or 90 days after actual completion or cessation if no such notice was recorded.8Justia. California Code Civil Code 9350-9364 – Stop Payment Notice
The second is a payment bond claim. On California public works contracts exceeding $25,000, the direct contractor must post a payment bond before work begins, and that bond guarantees payment to subcontractors and suppliers.9Justia. California Code Civil Code 9550-9566 – Payment Bond Your preliminary notice is the prerequisite. The court awards reasonable attorney’s fees to the prevailing party in bond claim litigation, which pushes both sides toward settling reasonable claims.
If you missed the preliminary notice entirely, there is a narrow backup for bond claims: written notice to the surety and the bond principal within 15 days after a notice of completion is recorded, or within 75 days after completion if none was recorded.9Justia. California Code Civil Code 9550-9566 – Payment Bond That window is tight and relying on it is risky. Serve the preliminary notice early instead.
Federal Jobs Don’t Use This Form
If your project is a federal public works contract rather than a state or local one, the California preliminary notice does not apply. Federal projects run under the Miller Act. First-tier subcontractors and suppliers can sue on the payment bond without any prior notice. Second-tier subcontractors and suppliers must give written notice to the prime contractor within 90 days of last furnishing labor or materials, and any suit must be filed within one year of that last date of work.10General Services Administration. The Miller Act – How Payment Bonds Protect Subcontractors and Suppliers Different forms, different deadlines, different courts. On a federal building, military installation, or other U.S. government job, start with the Miller Act, not this notice.
