California Mechanics Lien Rules for Contractors and Owners

The mechanics lien is one of the property-based remedies described in California consumer rights. This article covers the construction lien on real property under the Civil Code: who can claim one, the notice that comes before it, the recording deadlines, the lawsuit that keeps it alive, and the procedures an owner uses to clear it from title.

What a mechanics lien attaches to

A mechanics lien is a security interest in property acquired by someone who spent labor or materials working on that property (Cornell Legal Information Institute). In California construction, the lien attaches to the land and the improvement rather than to the person who failed to pay. That distinction is what gives the remedy its force: an unpaid subcontractor can reach the property even though the owner’s contract was with the general contractor.

Direct contractors, subcontractors, material suppliers, equipment lessors, laborers, and design professionals can all claim a lien for work furnished to a private work of improvement. The lien secures the reasonable value of the work provided or the price agreed to, whichever is less. Public projects work differently, a claimant on a public job pursues a stop payment notice or the payment bond instead of recording a lien against public property.

One threshold rule disposes of a large share of contractor claims before the deadlines matter. Under Cal. Bus. & Prof. Code § 7031, a person acting in the capacity of a contractor may not bring or maintain any action for the collection of compensation without alleging that they were duly licensed at all times during performance. An unlicensed contractor’s lien claim runs into the same bar.

The preliminary notice comes first

The preliminary notice is the step most often skipped and the one that most often kills a claim. Cal. Civ. Code § 8200 requires a claimant, before recording a lien claim, to give preliminary notice to the owner or reputed owner, the direct contractor, and the construction lender. Two exceptions narrow the rule: a laborer is not required to give preliminary notice at all, and a claimant with a direct contractual relationship with the owner gives preliminary notice only to the construction lender.

Timing controls how much of the debt the lien can secure. Cal. Civ. Code § 8204 states that preliminary notice shall be given not later than 20 days after the claimant has first furnished work, and that a claimant who gives notice late is entitled to record a lien only for work performed within the 20 days before the notice was served and any time after.

The notice is served by personal delivery, by first-class certified or registered mail, or by express delivery on each required recipient. Claimants commonly send it by certified mail with return receipt requested so the date of service can be proved later without a declaration from a process server.

Deadlines to record the claim of lien

Two different clocks apply, and which one governs depends on whether the claimant contracted directly with the owner.

A direct contractor may not enforce a lien unless the contractor records a claim of lien after completing the direct contract and before the earlier of two dates, set by Cal. Civ. Code § 8412: 90 days after completion of the work of improvement, or 60 days after the owner records a notice of completion or cessation.

Every other claimant works from a shorter outside date once the owner acts. Cal. Civ. Code § 8414 requires a claimant other than a direct contractor to record after ceasing to provide work and before the earlier of 90 days after completion of the work of improvement, or 30 days after the owner records a notice of completion or cessation.

The owner controls the shorter clock. Cal. Civ. Code § 8182 allows an owner to record a notice of completion on or within 15 days after the date of completion of a work of improvement, signed and verified by the owner. Recording it converts a subcontractor’s 90-day window into a 30-day window, which is why claimants monitor the county recorder’s index after finishing a job rather than counting from their own last day on site.

The claim of lien is recorded with the county recorder in the county where the property is located. Recording fees are set county by county and are separate from any later court filing fee.

What the recorded claim of lien contains

Cal. Civ. Code § 8416 specifies the form. The claim of lien is a written statement, signed and verified by the claimant, and a defect in its contents is a defense the owner can raise in the foreclosure action.

1. State the demand after just credits

   The claim states the claimant’s demand after deducting all just credits and offsets. Inflating the demand invites a challenge, and a claimant who records a lien for an amount known to be excessive can face liability for the owner’s costs in clearing it.

2. Identify the property, the owner, and the hiring party

   The claim names the owner or reputed owner, describes the site well enough to identify it for a lien, and states the name of the person who employed the claimant or to whom the claimant furnished work.

3. Describe the work furnished

   A general statement of the kind of work furnished by the claimant belongs in the claim. Descriptions that track the contract scope are easier to defend than one-line summaries.

4. Attach the Notice of Mechanics Lien and serve the owner

   Under Cal. Civ. Code § 8416, the claim must include the statutory NOTICE OF MECHANICS LIEN addressed to the owner, and the claimant serves a copy of the claim with that notice on the owner or reputed owner. Failure to serve the claim as required makes the lien unenforceable.

5. Record the proof of service affidavit

   The claim is recorded with a proof of service affidavit showing how, when, and on whom service was made. A claim of lien recorded without the affidavit does not satisfy the statute.

Enforcing the lien in court

Recording is not the end of the process. Cal. Civ. Code § 8460 requires the claimant to commence an action to enforce the lien within 90 days after recordation of the claim of lien, and provides that the claim of lien expires if the claimant does not commence an action within that time.

The enforcement action is a foreclosure suit filed in the superior court for the county where the property is located. The California courts locator identifies the right court for an address. The relief sought is an order that the property be sold and the proceeds applied to the lien, which is why these cases usually settle: an owner facing a forced sale of the improved property has a strong incentive to resolve the underlying payment dispute.

Missing the 90-day enforcement deadline ends the lien but not the debt. A claimant whose lien has expired under Cal. Civ. Code § 8460 can still sue on the contract or in quantum meruit against the party that hired them, subject to the ordinary limitations periods for those claims. What is lost is the security interest in the property, and with it the leverage.

How an owner clears a lien from title

An owner has three routes, and the right one depends on where the claim sits in its lifecycle.

The first is a lien release bond. Cal. Civ. Code § 8424 allows an owner or direct contractor to record a bond in an amount equal to 125 percent of the amount of the claim of lien, executed by an admitted surety insurer. Recording the bond frees the property; the claimant’s remedy shifts from the land to the bond. Owners refinancing or selling mid-dispute use this route because it clears title without waiting on the litigation.

The second is a petition to release. Under Cal. Civ. Code § 8480, the owner of property, or of any interest in property, subject to a claim of lien may petition the court for an order releasing the property when the claimant has not commenced an enforcement action within the time provided in section 8460. On the filing of the petition, Cal. Civ. Code § 8486 directs the clerk to set a hearing date not more than 30 days after the filing.

The third route is the simplest and the most common: the claimant records a release of lien after being paid or after settling. Nothing in the statute compels a claimant to record a release voluntarily, but a stale recorded claim that the claimant refuses to remove is what the section 8480 petition exists to address.
