Who can record a mechanics lien in California?

Any person who provides work authorized for a work of improvement — including direct contractors, subcontractors, individual laborers, material suppliers, equipment lessors, and certain design professionals — has a lien right under Civil Code section 8400 and following. The lien secures the value of the labor or materials actually furnished to the private property. The key limitation is procedural: the right exists, but it can only be enforced if the claimant met the preliminary notice and recording deadlines.

How long do I have to record a claim of lien?

It depends on your role. A direct contractor must record before the earlier of 90 days after completion of the work of improvement or 60 days after the owner records a notice of completion or cessation (section 8412). Every other claimant must record before the earlier of 90 days after completion or 30 days after a notice of completion or cessation (section 8414). If the owner never records a notice of completion, the 90-day-after-completion deadline controls.

What happens after I record the lien?

Recording alone does not collect the debt. You must file a lawsuit to foreclose the lien within 90 days after recording it. If you do not, the lien becomes unenforceable and you may be required to release it. This enforcement deadline is separate from and later than the recording deadline, and missing it is one of the most common ways an otherwise valid lien is lost.

How is a mechanics lien foreclosure different from a trust deed foreclosure?

A mechanics lien is enforced by a judicial foreclosure — a lawsuit — because the lienholder needs a court to establish and enforce the lien. A deed of trust, by contrast, is usually enforced through a nonjudicial trustee's sale without a lawsuit. The two remedies run on entirely different tracks and timelines, which is why a mechanics lien claimant must think in terms of filing suit, not conducting a trustee's sale.

Can an owner limit exposure to mechanics liens?

An owner can reduce risk by recording a notice of completion within 15 days of actual completion, which shortens claimants' recording windows to the 60-day and 30-day periods, and by using mechanisms such as conditional and unconditional lien waivers as payments are made. Owners of larger projects may also use payment bonds. None of these eliminate the lien right, but they compress deadlines and create a paper trail that helps ensure the people who did the work were actually paid.

California Mechanics Lien: Civil Code 8000 & Deadlines

TL;DR

A mechanics lien is the security a contractor, subcontractor, laborer, or material supplier can record against a private property when they aren't paid for work that improved it. In California, this remedy is grounded in the state Constitution and codified in the Civil Code at section 8000 and following, which took effect on July 1, 2012 as a recodification of the older lien statutes. The single most tested detail is the preliminary notice: under section 8410, a claimant may enforce a lien only if they first gave the required preliminary notice, and most claimants must serve that 20-day preliminary notice on the owner, direct contractor, and construction lender within 20 days of first furnishing labor or materials. Individual laborers are excused from giving preliminary notice, and a direct contractor generally must give it only to the construction lender. After the work, timing is strict: a direct contractor must record its claim of lien before the earlier of 90 days after completion of the work of improvement or 60 days after the owner records a notice of completion or cessation, while other claimants have 90 days after completion or, if the owner records a notice of completion, only 30 days. Once recorded, a lien must be enforced by a foreclosure lawsuit within 90 days, or it expires. The system is deliberately pro-claimant because California treats the mechanics lien as a constitutionally protected remedy for those who add value to real property. A perfected mechanics lien reaches equity that the homestead exemption does not protect from consensual and construction liens.

Where the mechanics lien comes from

California's mechanics lien is unusual among creditor remedies because its foundation is constitutional. Article XIV, section 3 of the California Constitution directs the Legislature to provide a lien for those who furnish labor or materials for a work of improvement, and courts have long treated the lien laws as remedial legislation to be construed liberally in favor of laborers and material suppliers. That constitutional backing is why the lien is powerful and why deadlines, though strict, are read to protect claimants where possible.

The operative statutes for private projects are found in Civil Code section 8000 and following — Part 6 of Division 4, titled Works of Improvement. This scheme was enacted in 2010 and became operative on July 1, 2012, recodifying the former lien statutes (the old section 3082 series) without major substantive change but reorganizing and modernizing the language. Public works are handled separately under section 9000 and following. Because a mechanics lien attaches to private real property, it does not apply to public projects, where claimants rely instead on stop payment notices and payment bonds.

The preliminary notice: the gate to everything

The preliminary notice is where most lien claims are won or lost, and it is the detail examiners return to. Under Civil Code section 8410, a claimant may enforce a lien only if the claimant has given preliminary notice to the extent required and made proof of that notice. The notice provisions begin at section 8200.

The general rule is that a claimant who is not in a direct contract with the owner must serve a preliminary notice on the owner, the direct contractor, and the construction lender within 20 days after first furnishing labor, service, equipment, or materials to the project. Serving late is not fatal, but the lien then reaches back only 20 days before the notice was finally given, so promptness protects the full claim. There are two important carve-outs in section 8200. An individual laborer who is owed wages need not give a preliminary notice at all. And a direct contractor — one who contracts directly with the owner — generally must give the preliminary notice only to the construction lender, if there is one, not to the owner. Getting these exceptions straight is a common exam point, because the notice obligation is not identical for every participant.

Recording and enforcing the lien: the deadlines

If payment still does not come, the claimant records a claim of lien in the county recorder's office where the property sits, and the recording deadlines depend on who the claimant is and whether the owner records a notice of completion or cessation.

Claimant	Deadline to record the claim of lien
Direct contractor (section 8412)	Before the earlier of: 90 days after completion of the work of improvement, or 60 days after the owner records a notice of completion or cessation
All other claimants (section 8414)	Before the earlier of: 90 days after completion, or 30 days after the owner records a notice of completion or cessation

Recording the lien is only the first half. Under the enforcement provisions, the claimant must file a lawsuit to foreclose the lien within 90 days after the lien is recorded. If no foreclosure action is filed in that window, the lien is unenforceable and must be released. This 90-day enforcement clock is separate from the recording deadlines above and is a frequent trap: a perfectly recorded lien still dies if the foreclosure suit is not filed in time. The owner can shorten the picture by recording a notice of completion within 15 days of actual completion, which compresses the claimants' recording windows to the shorter 60-day and 30-day periods.

How this fits the rest of California practice

For a licensee, the mechanics lien matters in two everyday situations: advising an owner who is about to start a remodel, and handling a sale where a recorded or threatened lien clouds title. A recorded mechanics lien is an encumbrance that will surface in a title search and generally must be resolved before closing, which is why it connects to disclosure and to the foreclosure remedies a lender or lienholder may pursue. A mechanics lien is enforced through a judicial foreclosure of the lien, which is distinct from the nonjudicial trustee's sale used for deeds of trust; for that contrasting process, see our guide to the nonjudicial foreclosure and trustee's sale under section 2924.

Because a lien can affect marketable title, a seller's obligation to disclose known defects and a buyer's review of title both intersect with lien risk; for the disclosure side, see our guide to the Transfer Disclosure Statement. And because a lien claim ultimately rests on a written contract and recorded documents, the formalities that govern real property agreements are in the background here too; see our guide to the statute of frauds for real property.

Frequently Asked Questions

Who can record a mechanics lien in California?: Any person who provides work authorized for a work of improvement — including direct contractors, subcontractors, individual laborers, material suppliers, equipment lessors, and certain design professionals — has a lien right under Civil Code section 8400 and following. The lien secures the value of the labor or materials actually furnished to the private property. The key limitation is procedural: the right exists, but it can only be enforced if the claimant met the preliminary notice and recording deadlines.
What is the 20-day preliminary notice, and who must give it?: It is a written notice a claimant serves near the start of work so the owner and lender know who might claim a lien. Most claimants who are not in a direct contract with the owner must serve it on the owner, direct contractor, and construction lender within 20 days of first furnishing labor or materials. Under section 8200, an individual laborer owed wages is excused entirely, and a direct contractor generally serves it only on the construction lender. Late service is allowed, but the lien then reaches back only 20 days before the notice was given.
How long do I have to record a claim of lien?: It depends on your role. A direct contractor must record before the earlier of 90 days after completion of the work of improvement or 60 days after the owner records a notice of completion or cessation (section 8412).

Bottom Line

California's mechanics lien is a constitutionally rooted remedy for those who improve private property, codified at Civil Code section 8000 and following and operative since July 1, 2012, but it is enforced through strict statutory notice, recording, and foreclosure deadlines. The gate to the whole remedy is the preliminary notice under section 8410: most claimants must serve a 20-day preliminary notice on the owner, direct contractor, and construction lender, while individual laborers are excused and direct contractors generally notify only the lender. Recording deadlines then turn on the claimant's role — a direct contractor records before the earlier of 90 days after completion or 60 days after a notice of completion (section 8412), and other claimants before 90 days after completion or 30 days after a notice of completion (section 8414). Recording is not enough: the claimant must file a foreclosure lawsuit within 90 days or the lien expires. Because a mechanics lien is enforced judicially and clouds title until resolved, it connects to the nonjudicial foreclosure process, the Transfer Disclosure Statement, and the statute of frauds.
