California Mechanics Lien: Deadlines, Forms & Filing Rules
California mechanics lien deadlines cited to statute: 20-day preliminary notice, record the lien within 90 days of completion, suit within 90 days of recording.
Serve within 20 days after first furnishing work or materials, on the owner, the direct contractor, and any construction lender. A late notice protects only work furnished in the 20 days before service and everything after.
Laborers are exempt (§8200(e)(1)); direct contractors serve the construction lender only, if any (§8200(e)(2)).
Record within 90 days after completion — or within 60 days after the owner records a notice of completion (direct contractor) / 30 days (all other claimants).
No notarization required — the recorder must accept the lien without acknowledgment (§8416(b)).
File suit within 90 days after the lien is recorded, or the lien expires. A recorded credit-extension agreement can extend the window, capped at 1 year after completion.

How California's mechanics lien deadlines work
California mechanics lien law is Part 6 of the Civil Code (§§8000-9566). Most claimants must serve a preliminary notice within 20 days after first furnishing work or materials (§8204(a)), addressed to the owner, the direct contractor, and any construction lender (§8200(a)). The notice can be served late, but it then protects only work furnished in the 20 days before service and everything after (§8204(a)). Serving no notice at all means no mechanics lien, no stop payment notice, and no payment-bond claim (§8200(a)).
The lien must be recorded with the county recorder of the county where the property sits, within 90 days after completion (§8412/§8414). If the owner records a notice of completion — which the owner can do within 15 days after completion (§8182(a)) — the window narrows to 60 days for the direct contractor (§8412(b)) and 30 days for everyone else (§8414(2)). No notarization is required: the recorder must accept the lien without acknowledgment (§8416(b)). After recording, a copy of the lien plus a statutorily formatted notice must be served on the owner — an un-served lien is unenforceable (§8416(c), §8416(e)).
Enforcement is a suit filed within 90 days after recording; after that the lien expires (§8460(a)). A written credit-extension agreement recorded with the county can stretch the window, but never past one year after completion (§8460(b)). Residential jobs carry separate contract rules, including a down payment cap of $1,000 or 10% of the contract price, whichever is less (Bus. & Prof. Code §7159(d)(8)(C)).
The notice duty depends on the role.
Direct contractor (direct contract with the owner)
No preliminary notice to the owner; where a construction lender exists, the notice goes to the lender only (§8200(e)(2)). Records the lien by the earlier of 90 days after completion or 60 days after a recorded notice of completion (§8412).
Subcontractor / supplier / equipment lessor
Preliminary notice within 20 days of first furnishing, served on the owner, the direct contractor, and the construction lender (§8200(a), §8204(a)). A late notice covers only the prior 20 days plus work after service. Records the lien within 90 days of completion — 30 days after a recorded notice of completion (§8414).
Laborer
Exempt from the preliminary notice requirement entirely (§8200(e)(1)).
Everyone who records a lien
A copy of the recorded lien plus the 10-point bold statutory notice must be served on the owner (§8416(c)); an unserved lien is unenforceable (§8416(e)).
California mechanics lien questions, answered straight.
What is the deadline to record a California mechanics lien?
Within 90 days after completion (Cal. Civ. Code §8412/§8414). If the owner records a notice of completion, the window narrows to 60 days for the direct contractor (§8412(b)) and 30 days for all other claimants (§8414(2)); the owner may record that notice within 15 days after completion (§8182(a)).
What happens if the 20-day preliminary notice is served late?
The notice is still effective, but only for work furnished in the 20 days before service and for everything after (§8204(a)). Serving no notice forfeits the mechanics lien, the stop payment notice, and payment-bond rights (§8200(a)).
Does a California mechanics lien need to be notarized?
No. The recorder must accept the lien for recording without acknowledgment (§8416(b)); the lien is signed and verified instead. County recording fees vary — Los Angeles County’s posted schedule, checked on 10/09/2026, is about $111 for the first page plus $3 for each additional page (per the county’s posted fee schedule at that time — fees change).
Which lien waiver form does California require?
California prescribes four statutory waiver formats (§§8132-8138), and a contract term by which another party waives or impairs a claimant’s lien rights is void unless and until the claimant executes a statutory waiver (§8122). The conditional forms take effect on payment; the unconditional forms take effect on signing, so the unconditional waiver belongs only after funds have cleared.
How long does a California mechanics lien last?
A suit to enforce must be filed within 90 days after the lien is recorded, or the lien expires (§8460(a)). A recorded credit-extension agreement can extend the window, capped at one year after completion (§8460(b)).
