At a glance
| Governing law | Cal. Civ. Code §§ 8400–8494 (private construction liens); preliminary notice and completion rules appear in §§ 8180–8204 |
|---|---|
| Who can claim a lien | Direct contractors, subcontractors, suppliers, equipment lessors, laborers, and design professionals (§ 8400); required contractor licensure limits enforcement (Bus. & Prof. Code § 7031(c)) |
| Preliminary notice | Generally due within 20 days after first furnishing; laborers exempt, owner-direct claimants notify only the lender if any; late notice covers only work from 20 days before service onward (§§ 8200, 8204) |
| Deadline to file the lien | Direct contractor: after its contract ends and before 90 days after completion, or 60 days after an effective recorded completion/cessation notice; other claimants: after ceasing work and before 90 or 30 days, respectively (§§ 8412, 8414) |
| Notice of completion effect | Recorded completion/cessation notice cuts 90 days to 60 for direct contractors and 30 for others; ordinarily the owner must send copies within 10 days or the shortened period is ineffective for an unnotified covered claimant (§§ 8190, 8412, 8414) |

Requirements one by one
Governing law and who may claim
Civil Code § 8400 gives lien rights for authorized improvement work to direct contractors, subcontractors, material suppliers, equipment lessors, laborers, and design professionals. A person doing work for which a contractor license is required must also meet the licensing rule: Business and Professions Code § 7031(c) makes the security interest unenforceable if that person was not duly licensed throughout the work.
Preliminary notice
Civil Code § 8200 ordinarily requires notice to the owner, the direct contractor, and any construction lender before a lien is recorded. Laborers are exempt; someone contracting directly with the owner gives notice only to the lender, if there is one. Under § 8204, a notice served after the first 20 days still protects work done within the 20 days before service and later work, but not earlier work.
Recording deadline and completion notice
Completion under § 8180 includes actual completion, owner occupation or use plus cessation of labor, 60 continuous days without labor, or a recorded cessation notice after 30 continuous days without labor. A direct contractor records after completing its own contract and before the earlier of 90 days after project completion or 60 days after the owner records an effective notice of completion or cessation (§ 8412). Other claimants record after they stop providing work and before the earlier of 90 days after completion or 30 days after an effective recorded notice (§ 8414).
The shortened period ordinarily depends on a second step. Under § 8190(a), the owner must give a copy of a recorded completion or cessation notice within 10 days to the direct contractor and any claimant who gave preliminary notice. If a covered person is not given that copy, § 8190(c) makes the notice ineffective to shorten that person's lien-recording time. Section 8190(d)(1) exempts an owner occupying a personal residence of four or fewer units from this copy duty.
Service and foreclosure
The lien claim itself must include a proof-of-service affidavit and the specified warning notice (§ 8416(a)(7)–(8)). Section 8416(c) requires a copy of the claim, including the warning, to be served on the owner or reputed owner by a listed mailing method; it permits an alternate addressee if the owner cannot be served that way. Under § 8416(e), failure to serve the copy as prescribed makes the claim unenforceable.
Section 8460 requires a foreclosure action within 90 days after recording. A recorded owner–claimant agreement extending credit can move the suit deadline to 90 days after the credit expires, but never beyond one year after completion; the statute also specifies when that agreement must be recorded.
What trips people up
Serving a preliminary notice late narrows the work protected by a lien (§ 8204). The service rule for the lien claim is separate: the proof-of-service affidavit belongs in the claim when it is recorded (§ 8416(a)(7)), and missing service makes the lien unenforceable (§ 8416(e)).
Common questions
Does a recorded completion notice always cut my filing time? No. Section 8190(c) preserves the longer period for a covered claimant whom the owner failed to notify. The small occupied-residence exception to the owner's copy duty is in § 8190(d)(1).
Can the owner and claimant extend the foreclosure deadline? Yes, if they agree to extend credit and record the notice on the terms in § 8460(b); the outer limit is one year after completion.
