Who Must Serve a Preliminary Notice?
The answer depends on the project type and the claimant’s contractual tier. On a private work, many subcontractors, lower-tier subcontractors, material suppliers, equipment providers, and other claimants must serve notice before pursuing specified statutory remedies.
Under California Civil Code section 8200, a laborer is not required to give private-work preliminary notice. A claimant that contracts directly with the owner generally gives notice only to the construction lender or reputed construction lender, if one exists. This rule can matter to direct contractors and other companies that contract directly with an owner.
On a public work, Civil Code section 9300 exempts laborers and claimants that have a direct contractual relationship with the direct contractor. Lower-tier subcontractors and suppliers should not assume that exemption applies to them.
When Is the Preliminary Notice Due?
The safest practice is to serve it before work begins or within 20 days after first furnishing work. The controlling date ordinarily is the first date the claimant furnished project labor, services, equipment, or materials. It is not necessarily the date of the first invoice, payment application, delivery batch, or missed payment.
Under Civil Code section 8204, a private-work claimant may serve notice after the first 20 days. The notice generally preserves lien, stop payment notice, and payment bond remedies only for work furnished during the 20 days before service and at any time afterward. Civil Code section 9304 provides a comparable rule for public-work stop payment notice and bond rights.
Separate private- and public-work payment bond statutes may offer a limited postcompletion written-notice path when no preliminary notice was given. Those paths have short deadlines and additional conditions, and they do not preserve mechanics lien or stop payment notice rights. See Civil Code section 8612 and section 9560.
Short Scenario
An electrical subcontractor begins work on a private commercial project but does not serve its preliminary notice until several weeks later. The late notice may preserve specified remedies for work furnished during the 20 days before service and for later work. Earlier work may fall outside the remedies preserved by that notice.
Daily reports, delivery tickets, rental records, time entries, and project correspondence can become important when the first-furnishing date or protected amount is disputed.
Private Work and Public Work Requirements
Private and public projects do not use the same notice path. Public property is not subject to a private mechanics lien, so public-work claimants rely on different statutory remedies.
| Project |
Typical Required Recipients |
Remedies the Notice May Preserve |
| Private work |
Owner or reputed owner, direct contractor or reputed direct contractor, and construction lender or reputed construction lender, if any |
Mechanics lien, stop payment notice, and payment bond claim |
| Public work |
Public entity and direct contractor, subject to statutory exemptions |
Stop payment notice and payment bond claim |
The identity of the owner, public entity, direct contractor, and lender should be verified. A private direct contractor must make the owner’s and construction lender’s names and addresses available to a person seeking to give notice under Civil Code section 8208.
What Must the Notice Contain, and How Is It Served?
The notice must contain statutory project, party, work, and price information and must be served through an authorized method. A familiar-looking form is not necessarily compliant.
The information generally includes:
- Owner or reputed owner’s name and address
- Direct contractor’s name and address
- Construction lender’s name and address, if applicable
- A site description sufficient for identification
- The sender’s name, address, and project relationship
- A general description of the work
- The party for whom the work is provided
- An estimate of the total price and any current demand
A private-work notice also must include the boldface statutory warning prescribed by Civil Code section 8202. The general content rules appear in Civil Code section 8102.
Authorized methods include personal delivery, registered or certified mail, express mail, overnight delivery by an express service carrier, and a specified substitute-service procedure. An email or ordinary project-platform transmission should not be assumed to satisfy the statute. Electronic service may qualify only when the recipient has agreed in writing and the statutory conditions are satisfied. See Civil Code section 8106, section 8110, and section 8112.
The sender should keep the complete notice, a proof-of-notice declaration, postal or carrier receipts, tracking records, and any returned envelope. Civil Code section 8118 addresses proof of notice.
What Should an Owner or Developer Do After Receiving Notice?
Treat the notice as a project record, not proof that a default has occurred. Confirm that the sender is furnishing work, match it to the contractor’s subcontractor and supplier list, and track the sender against payment applications and scheduled disbursements.
Depending on the project and payment status, an owner or developer may also:
- Request the applicable statutory conditional release before or with payment, and request an unconditional release only after the claimant can accurately acknowledge receipt of payment.
- Investigate payment disputes before releasing disputed funds.
- Consider joint checks where appropriate.
- Keep the notice, envelope, and delivery information in the project file.
- Coordinate any notice of completion or cessation with counsel and the project team.

Documents to Gather
A reliable notice review starts with the project records that establish the parties, tier, work, and timeline.
- Prime contract, subcontract, purchase order, and change orders
- Project address, legal description, and job-information sheet
- Owner, public entity, direct contractor, and lender information
- Payment and performance bond documents
- First-work dates, daily reports, time records, and delivery tickets
- Invoices, payment applications, and payment history
- Notices, proof of service, tracking records, and returned mail
- Notices of completion or cessation and lien releases
Frequently Asked Questions
Does a preliminary notice mean payment is late?
No. It is commonly served near the start of work, before an invoice is due. It preserves potential rights and gives required parties information about the sender.
Can a late preliminary notice still help?
Yes, but its reach may be limited. It generally preserves the specified remedies for work furnished during the 20 days before service and for later work, not all earlier work.
Does one notice cover change orders and later work?
For a private work, one preliminary notice to each required recipient generally covers all work provided by the claimant for that work of improvement, including later work. If the claimant provides work under contracts with more than one subcontractor, a separate preliminary notice is required for each contract. Public-work notice requirements should be analyzed separately under Civil Code sections 9300 through 9306.
Must the notice be recorded?
No. Service on the required recipients is what preserves the applicable rights. A private-work notice may be filed with the county recorder for the limited purpose described in Civil Code section 8214, but that filing does not replace service or create constructive notice.
Does timely notice guarantee lien or bond rights?
No. A claimant must separately satisfy every requirement for the remedy pursued, including eligibility, content, service, recording, and enforcement deadlines.
