Short answer: California Civil Code § 8200 requires most construction claimants to serve a preliminary notice on the property owner, the direct contractor, and the construction lender within 20 days of first furnishing labor or materials. Compliance is a prerequisite to a valid mechanics lien, stop payment notice, or payment bond claim. A claimant in direct contract with the owner must still serve the construction lender.
Key Takeaways
- Preliminary notice goes to the owner, the direct contractor, and the construction lender (Civ. Code § 8200(a)).
- It is a necessary prerequisite to a valid lien claim, stop payment notice, and payment bond claim (Civ. Code § 8200(c)–(d)).
- A direct contractor is exempt only as to the owner, it must still serve the construction lender (Civ. Code § 8200(e)).
- A late notice is not fatal, but limits the claim to work furnished in the 20 days before service and thereafter.
- Retain proof of service. The notice is only as good as the ability to prove it was served.
The preliminary notice is the least glamorous document in California construction practice and the one most often responsible for a claimant walking away with nothing. It costs almost nothing to serve. It is a prerequisite to nearly every payment remedy the Civil Code provides. And it is regularly skipped by parties who believe, usually incorrectly, that an exemption applies to them.
What the statute requires
Before recording a lien claim, giving a stop payment notice, or asserting a claim against a payment bond, a claimant must give preliminary notice to three categories of person (Civ. Code § 8200(a)):
- The owner or reputed owner
- The direct contractor or reputed direct contractor to which the claimant provides work, either directly or through one or more subcontractors
- The construction lender or reputed construction lender, if any
The consequences of skipping it are set out explicitly. Compliance is a necessary prerequisite to the validity of a lien claim or stop payment notice (Civ. Code § 8200(c)), and to the validity of a claim against a payment bond (Civ. Code § 8200(d)). Preliminary notice is also among the conditions to enforcing a lien under Civil Code section 8410.
Notice is generally served within 20 days after the claimant first furnishes labor, service, equipment, or materials to the project.
The exemption is narrower than people think
The most commonly cited exemption is for parties in direct contract with the owner. The statute provides that a claimant with a direct contractual relationship with an owner or reputed owner is required to give preliminary notice only to the construction lender or reputed construction lender (Civ. Code § 8200(e)).
Read that carefully. A general contractor is relieved of the obligation to notify the owner, which makes sense, since the owner hired it and knows it is there. The general contractor is not relieved of the obligation to notify the construction lender. On a financed project, a general contractor that serves no preliminary notice at all has an unsecured claim, and the lender's deed of trust is frequently the only meaningful position in the property.
This is a recurring and expensive misunderstanding. “I contracted directly with the owner, so I don't need a prelien” is half of a correct sentence.
Laborers are separately treated, as are certain public entity and residential circumstances. Anyone relying on an exemption should confirm it against the statute rather than industry custom.
Serving a late notice
A late preliminary notice is not the same as no preliminary notice, but the difference is smaller than it sounds. A claimant who serves late is not precluded from giving notice, but the resulting claim is limited to the value of work and materials furnished during the 20 days preceding service of the notice, and any time thereafter.
For a supplier that front-loaded its deliveries, this is functionally a total loss. For a subcontractor with continuing monthly work, serving a late notice may preserve a meaningful portion of the balance. The practical rule: if the notice was missed, serve it immediately rather than concluding the claim is dead. Every day of delay is another day of work stripped out of the recoverable amount.
Getting service right
The notice must comply with the content and service requirements of Civil Code sections 8100 et seq. Common failure points:
Wrong owner. Ownership on construction projects is frequently held by an entity that is not the one signing the contract or writing the checks. The “reputed owner” language provides some protection, but a notice sent to a property manager or an affiliated entity may not reach the party whose interest is being encumbered. Pull the vesting deed.
Missed lender. Construction lenders do not announce themselves to lower-tier trades. The recorded deed of trust does. A title search at the start of the job is the reliable method.
No proof of service retained. The notice is only as good as the ability to prove it was served. Retain the certified mail receipts, tracking records, and a proof of service. Reconstructing service two years later from memory does not work.
Serving once and never again. If the ownership changes, if a lender is added mid-project, or if the claimant begins working through a different upstream contractor, the notice picture changes.
Why owners and developers should read them
Preliminary notices are not merely a claimant's obligation. They are an owner's early-warning system. Each notice identifies a party with potential lien rights against the property, which allows an owner to:
- Track the actual composition of the project team, which frequently differs from the schedule of values
- Condition progress payments on conditional and unconditional waivers from the parties who have noticed
- Identify unauthorized lower-tier subcontractors before their work is buried
- Assess exposure before recording a notice of completion and starting the shortened lien clock
An owner that files preliminary notices in a drawer without cross-referencing them against lien waivers is accumulating exposure it could easily have measured.
The defense side
Because preliminary notice is a condition precedent, defects in it are among the first things examined when a lien is challenged. Where a claimant was required to serve notice and did not, or served a notice that failed the statutory requirements, the lien is vulnerable, including on a petition for a release order under Civil Code sections 8480 through 8488, where the claimant bears the burden of proof on the validity of the lien and the prevailing party is entitled to reasonable attorney's fees (Civ. Code § 8488).
That fee-shifting provision cuts both directions, which is why a preliminary notice defect should be confirmed rather than assumed before a petition is filed.
The practical takeaway
Serve preliminary notice on every project, to every statutory recipient, within 20 days of first furnishing. The document costs a few dollars. The analysis of whether an exemption applies costs far more than that, and the consequence of getting it wrong is the loss of the security that makes construction payment claims collectible.
Frequently Asked Questions
Who has to send a preliminary notice in California?
Subcontractors, material suppliers, equipment lessors, and most other claimants must serve preliminary notice on the owner, direct contractor, and construction lender within 20 days of first furnishing (Civ. Code § 8200). Laborers are treated separately.
Does a general contractor need to send a preliminary notice?
A claimant in direct contract with the owner is required to give preliminary notice only to the construction lender (Civ. Code § 8200(e)). On a lender-financed project, a general contractor that serves nothing has an unsecured position against the lender’s deed of trust.
What happens if I send the preliminary notice late?
Lien rights are not extinguished, but the claim is limited to the value of work furnished during the 20 days preceding service and thereafter. Serve immediately rather than abandoning the claim, every day of delay strips more work out of the recoverable amount.
Is a preliminary notice the same as a mechanics lien?
No. A preliminary notice does not encumber the property. It is a notification that a party is furnishing work and may later claim a lien. It is a precondition to recording a lien, not a lien itself.
