Short answer: In California, a direct contractor must record a mechanics lien within 90 days after completion of the work of improvement, or within 60 days after the owner records a notice of completion or cessation, whichever is earlier (Civ. Code § 8412). Everyone else, subcontractors and material suppliers, has 90 days after completion, or 30 days after a recorded notice of completion (Civ. Code § 8414). A lawsuit to foreclose the lien must then be filed within 90 days of recording (Civ. Code § 8460).
Key Takeaways
- Direct contractors: 90 days after completion, or 60 days after a recorded notice of completion or cessation (Civ. Code § 8412).
- Subcontractors and suppliers: 90 days after completion, or 30 days after a recorded notice of completion (Civ. Code § 8414).
- The 90-day clock runs from completion of the entire project, not the claimant’s last day on the job (Civ. Code § 8180).
- A 60-day continuous cessation of labor counts as completion by operation of law and starts the clock on a stalled project.
- Suit to foreclose must be filed within 90 days of recording the lien, or the lien is unenforceable (Civ. Code § 8460).
The California mechanics lien is one of the most powerful collection tools available to anyone who improves real property. It is also one of the most unforgiving. The remedy is entirely statutory, and the statutes are built around a chain of deadlines. Miss any single link in that chain and the security interest disappears, no matter how strong the underlying debt is, and no matter how clearly the work was performed.
What makes the system genuinely difficult is not that the deadlines are short. It is that the deadlines run from events that are frequently ambiguous, sometimes unknown to the claimant at the time, and occasionally within the control of the party who does not want to pay. A subcontractor can be diligent, track its own last day on the job, calendar ninety days, and still be too late, because an owner recorded a notice of completion three weeks earlier and the window quietly shortened to thirty days.
This article walks the entire timeline in order, from first delivery of labor or materials to the lawsuit that perfects the lien.
The chain, in order
There are four links. Each one is independently fatal.
- Preliminary notice, generally within 20 days of first furnishing labor or materials.
- Recording the claim of lien, 90, 60, or 30 days, depending on who you are and what the owner recorded.
- Filing suit to foreclose the lien, 90 days from recording.
- Recording a notice of pendency of action, to preserve the lien against subsequent purchasers and encumbrancers.
Link one: the preliminary notice
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 the owner or reputed owner, the direct contractor, and the construction lender, if any (Civ. Code § 8200(a)). Compliance is a necessary prerequisite to the validity of a lien claim or stop payment notice (Civ. Code § 8200(c)), and to a payment bond claim (Civ. Code § 8200(d)).
The notice is generally served within 20 days after the claimant first furnishes work. Serving late does not extinguish lien rights entirely, but it narrows them severely: the claim is limited in substance to the value of work furnished in the 20 days preceding service and thereafter. On a job where a supplier delivered most of its material in month one and served notice in month five, that limitation can eliminate nearly the entire claim while technically leaving “lien rights” intact.
A claimant with a direct contractual relationship with the owner is required to give preliminary notice only to the construction lender, if there is one (Civ. Code § 8200(e)). This is the provision most often misread. A general contractor is not exempt from preliminary notice in the abstract, it is exempt as to the owner and, obviously, as to itself. If the project is lender-financed, the general still has a notice obligation, and blowing it can matter enormously when the lender's deed of trust is the only meaningful equity in the property.
The preliminary notice requirements are detailed enough to warrant their own treatment. See our article on who must serve the 20-day notice, who is exempt, and what happens when it is served late.
Link two: recording the claim of lien
This is where most claims are lost, because the deadline depends on two variables, the claimant's role and whether the owner recorded a notice.
If no notice of completion or notice of cessation is recorded:
Everyone, direct contractors, subcontractors, and material suppliers alike, has 90 days after completion of the work of improvement (Civ. Code §§ 8412, 8414).
If the owner records a notice of completion or notice of cessation:
- A direct contractor has 60 days after recording (Civ. Code § 8412(b)).
- Everyone other than the direct contractor has 30 days after recording (Civ. Code § 8414(b)).
Note the counterintuitive structure. The party furthest from the owner, with the least visibility into what the owner records, gets the shortest window. A second-tier supplier who has never spoken to the owner and does not monitor the county recorder can lose its rights in thirty days without ever learning that the clock started.
What “completion” actually means
The 90-day deadline runs from completion of the entire work of improvement, not from the claimant's last day on the job. A drywall subcontractor who finished in March on a project that reached completion in September has until December, not June.
When the project is not actually completed, completion is defined by statute (Civ. Code § 8180) as, among other events:
- Occupation or use of the work of improvement by the owner, accompanied by cessation of labor
- Cessation of labor for a continuous period of 60 days
That second trigger deserves attention on stalled projects. If a developer runs out of money and the site goes quiet, completion occurs by operation of law at the end of the 60-day cessation, and the 90-day recording window begins running from that date. Claimants waiting for the project to restart routinely discover that their rights expired while they waited.
Whether occupation or use has occurred is intensely fact-driven. An owner moving back into a residence is straightforward. An owner storing materials in a partially finished building, or bringing in furniture in anticipation of use, is contested territory.
How the owner accelerates the clock
An owner may record a notice of completion within 15 days after the date of completion (Civ. Code § 8182). An owner may also record a notice of cessation after labor has ceased for a continuous period of at least 30 days (Civ. Code § 8188), cutting in half the 60-day cessation period that would otherwise define completion.
There is a service requirement attached. Where the owner fails to deliver a copy of the notice to the direct contractor within the statutory period after recording, the shortened deadline does not apply as to that contractor, and the longer 90-day period governs. Defective or unserved notices are a recurring source of viable liens that both sides initially assume are time-barred.
Recording too early is also a problem
The deadlines are not merely outer limits. A direct contractor may not record until after completing the direct contract (Civ. Code § 8412). A claimant other than a direct contractor may not record until it has ceased to provide work (Civ. Code § 8414). Continuing to perform contract work after recording can invalidate the lien.
Similarly, a lien recorded for amounts not yet due is overstated and vulnerable (see Civ. Code §§ 8430–8434). The instinct to record early as leverage is understandable and frequently counterproductive.
The contents requirement
A claim of lien must be signed and verified, and must contain the statutory elements set out in Civil Code section 8416, the demand after deducting just credits and offsets, the name of the owner or reputed owner, a general statement of the work furnished, the name of the person by whom the claimant was employed, and a description of the site sufficient for identification. Section 8416 also requires a proof of service affidavit reflecting service of the lien on the owner. A lien that is recorded on time but omits required content is not a safe lien.
Link three: the foreclosure lawsuit
An action to enforce the lien must be commenced within 90 days after recording the claim of lien (Civ. Code § 8460). This deadline is short, absolute, and independent of everything that came before. A perfectly recorded lien that sits for 91 days is unenforceable, and the owner may then demand a release whether or not the claimant has been paid.
The parties may extend the deadline by written agreement recorded with the county recorder, a mechanism worth knowing about when settlement discussions are genuinely progressing and neither side wants the expense of a complaint. Informal assurances that “we're working on it” extend nothing.
Link four: notice of pendency
Recording a notice of pendency of action after filing suit preserves the lien's effect against parties who acquire an interest in the property during the litigation. Omitting it does not extinguish the lien between the original parties, but it can leave the claimant chasing a defendant who no longer owns anything.
Why the deadlines are strict
California courts have long recognized that mechanics lien law exists to protect those who furnish labor and materials, and that the statutes should be liberally construed in their favor (see, e.g., Connolly Development, Inc. v. Superior Court (1976) 17 Cal.3d 803). But liberal construction operates on ambiguity in the statute, not on missed dates. Courts have no equitable authority to extend a recording deadline because the claimant was owed money, was strung along, or was unaware that a notice of completion had been recorded.
The practical consequence is that the strategy conversation has to happen well before the deadline, not after.
Practical steps that preserve options
Serve preliminary notice on every project, without exception. The cost is trivial. The analysis of whether an exemption applies is not worth having under deadline pressure, and the exemption is narrower than most parties assume.
Monitor the recorder for notices of completion. On any project of consequence, a recorded notice can compress a 90-day window to 30 days without any communication to lower-tier claimants. Title monitoring services and periodic searches are inexpensive relative to the exposure.
Fix the completion date early and in writing. Ambiguity about completion is the single most common source of lien litigation. Document the last day of work, photograph site conditions, and preserve delivery records.
Calendar backward from the earliest possible trigger. When completion is uncertain, calculate from the earliest defensible date rather than the most favorable one.
Treat a 60-day site shutdown as a completion event. Do not wait for a stalled project to restart.
Calendar the 90-day foreclosure date on the day the lien is recorded. More liens expire from inattention after recording than from any other cause.
When the deadline has already passed
An expired lien is not necessarily the end of the claim. The underlying debt survives, and breach of contract, common count, and quantum meruit claims carry a four-year or two-year statute of limitations depending on whether the contract was written or oral. Prompt payment penalties under Civil Code section 8800 and Business and Professions Code section 7108.5 are independent statutory remedies that do not depend on lien rights at all. On public works, stop payment notice and payment bond remedies operate on their own timelines.
What is lost is the security interest in the property, which is often the difference between a collectible judgment and an uncollectible one, but is not the whole case.
Frequently Asked Questions
How long do I have to file a mechanics lien in California?
A direct contractor has 90 days after completion of the work of improvement, shortened to 60 days if the owner records a notice of completion or cessation (Civ. Code § 8412). Subcontractors, suppliers, and all other claimants have 90 days after completion, shortened to 30 days by a recorded notice of completion (Civ. Code § 8414).
Does the 90-day deadline run from my last day on the job?
No. It runs from completion of the entire work of improvement, not from the individual claimant’s last day. A subcontractor who finished in March on a project completed in September calculates from September.
What happens if the project stalls and never finishes?
Cessation of labor for a continuous period of 60 days constitutes completion by operation of law (Civ. Code § 8180), and the 90-day recording window begins running from the end of that period. An owner can accelerate this further by recording a notice of cessation after 30 days of cessation (Civ. Code § 8188).
Can a mechanics lien deadline be extended?
The deadline to file the foreclosure action may be extended by written agreement recorded with the county recorder. The recording deadlines themselves cannot be extended by agreement, and courts have no equitable power to excuse a missed deadline.
What happens if I miss the mechanics lien deadline entirely?
The security interest in the property is lost, but the underlying debt survives. Breach of contract, common count, prompt payment penalty claims under Civ. Code § 8800 and Bus. & Prof. Code § 7108.5, and payment bond claims run on separate timelines and may remain available.
