California mechanics lien guide and deadlines
2026-10-1810 min read
California's mechanics lien law sits in Civil Code Part 6, from § 8000 on, and it is stricter about paperwork than about deadlines. The dates are short but plain. The traps are the notice of completion that nobody mails you, a claim served without the statutory notice, and a lien left to expire on day 91. This guide walks the statute in the order a subcontractor meets it, with one job worked from first day to foreclosure suit. For the general sequence that applies in every state, start with how to file a mechanics lien.
Who holds a lien right in California
Civil Code § 8400 gives a lien right to any person that provides work authorized for a work of improvement, and names six: direct contractor, subcontractor, material supplier, equipment lessor, laborer and design professional. Under § 8404 work is authorized if the owner asked for or agreed to it, or if a direct contractor, subcontractor, architect, project manager or anyone else in charge of the work provided or authorized it. The test is who sent you to the job, not whether you hold a contract with the owner. A third-tier electrical sub has the same lien right as the general.
| Claimant | Preliminary notice goes to | Recording rule |
|---|---|---|
| Direct contractor (contract with the owner) | Construction lender only, if there is one | § 8412 |
| Subcontractor, any tier | Owner, direct contractor, construction lender | § 8414 |
| Material supplier | Owner, direct contractor, construction lender | § 8414 |
| Equipment lessor | Owner, direct contractor, construction lender | § 8414 |
| Laborer | None required | § 8414 |
License
Business and Professions Code § 7031(a) bars a contractor from bringing any action to collect pay for licensed work unless it alleges it was duly licensed at all times during the work. A California lien is enforced only by a lawsuit, so a lapse in your license mid-job is a problem for the lien too. Check your license status before you record, not after.
The who can file guide covers the general rules across states. In California the role you hold changes two things: who gets your preliminary notice, and which recording section sets your deadline.
The 20-day preliminary notice
Before you record a lien, give a stop payment notice or claim against a payment bond, § 8200 requires a preliminary notice to the owner, the direct contractor and the construction lender. Compliance is a necessary prerequisite to validity, and § 8410 adds that you may enforce a lien only if you gave the notice and can make proof of it. Keep the certified mail receipts with the job file.
The notice is due 20 days after you first furnish work (§ 8204). Late is not fatal: a late notice still protects work done in the 20 days before you served it and everything after. Everything before that window is gone. Under § 8202 the notice must describe the work, estimate its total price and carry the statutory “Notice to Property Owner” in bold. The preliminary notice generator drafts one in a couple of minutes, so send it the day you mobilize.
Two California details most guides skip. A licensed sub whose contract pays more than $400 and that fails to give the notice hands the license board grounds for discipline (§ 8216). And the notice puts you on the owner's list: it is the reason the owner has to send you a copy of a notice of completion, which the next section explains.
Completion, and the notice that shortens everything
Your recording deadline runs from completion of the whole work of improvement, not from your last day on site. Section 8180 says completion happens on the first of these:
- 01Actual completion of the work of improvement.
- 02The owner occupies or uses it and labor stops.
- 03Labor stops for a continuous 60 days.
- 04Labor stops for 30 days and the owner records a notice of cessation.
The owner can then record a notice of completion, on or within 15 days after completion, signed and verified (§ 8182), or a notice of cessation once labor has stopped for at least 30 days (§ 8188). Either one shortens your window. On a job with several direct contracts, § 8186 lets the owner record a notice for one contract only, and a sub under that contract is treated as having stopped work on that date. The building can still be going up when your clock starts.
Lien deadline
Section 8190 makes the owner give a copy of a recorded notice of completion or cessation, within 10 days, to the direct contractor and to every claimant that served it a preliminary notice. If the owner skips you, the notice does not shorten your time. An owner who lives in the home, in a dwelling of four or fewer units, is exempt, so on that remodel nobody has to tell you. Check the county recorder yourself once the work looks finished.
Recording deadlines
California sets two clocks and you take whichever runs out first. Neither starts on your last invoice or your last day on site.
| Claimant | Window opens | Closes at the earlier of | Cite |
|---|---|---|---|
| Direct contractor | After it completes its direct contract | 90 days after completion, or 60 days after a notice of completion or cessation is recorded | § 8412 |
| Everyone else | After it stops providing work | 90 days after completion, or 30 days after a notice of completion or cessation is recorded | § 8414 |
The window has a front edge as well as a back one. A sub that records while still on the job has recorded too early. Put your own dates into the mechanics lien deadline calculator, then check the county recorder for a notice of completion before you trust the 90-day figure.
A worked timeline
An electrical subcontractor on a tenant improvement in Los Angeles County, hired by the general, with a $148,000.00 subcontract. At closeout it is owed $26,400.00: the July pay application of $19,000.00 and $7,400.00 of retention. Here is every date, counted from the statute.
| Date | What happens | Rule | Cite |
|---|---|---|---|
| 2026-03-04 | Electrical sub starts rough-in | First furnishing: day 0 for the notice | § 8204 |
| 2026-03-05 | Preliminary notice mailed to owner, GC and lender | Served on day 1, proof of mailing filed | §§ 8200, 8410 |
| 2026-03-24 | Last day for a notice that covers all the work | 20 days after first furnishing | § 8204 |
| 2026-07-17 | Sub finishes trim-out and leaves site | The sub may record from here, not before | § 8414(a) |
| 2026-08-07 | Work of improvement complete; tenant moves in | Starts the 90-day outside limit | §§ 8180, 8414 |
| 2026-08-12 | Owner records a notice of completion | Within 15 days of completion, so it is valid | § 8182(a) |
| 2026-08-22 | Owner's copy of the notice due to the sub | 10 days after recording; the sub served notice | § 8190 |
| 2026-09-04 | Sub records its claim and mails the owner a copy | A week inside the window | § 8416 |
| 2026-09-11 | Last day to record for the sub | 30 days after the notice beat 90 after completion | § 8414(b) |
| 2026-11-05 | Outside limit had no notice been recorded | 90 days after completion | § 8414(b)(1) |
| 2026-12-03 | Foreclosure suit must be on file | 90 days after the Sep 4 recording | § 8460(a) |
The notice of completion cost the sub 55 days. Had the owner not mailed it the copy owed under § 8190, the notice would not have shortened the sub's time and November 5 would have governed again. Do not plan on that. Proving a copy never arrived is a fight, and recording on September 4 costs nothing.
The general on the same job had 60 days from the notice, which lands on Sunday, October 11. Never let a deadline you are relying on fall on a weekend. Record the Friday before.
What the claim must say, and who gets a copy
Section 8416(a) lists what a California claim of mechanics lien contains. It is a written statement, signed and verified by the claimant, with these eight items:
- 01Your demand after deducting all just credits and offsets.
- 02The name of the owner or reputed owner, if known.
- 03A general statement of the kind of work you furnished.
- 04Who employed you, or who you furnished the work to.
- 05A description of the site sufficient to identify it.
- 06Your address.
- 07A proof of service affidavit from whoever mails the copy to the owner.
- 08The statutory Notice of Mechanics Lien, in at least 10-point bold type.
Verified does not mean notarized. Under § 8416(b) the recorder must accept a claim in proper form without an acknowledgment. The notarization guide covers where a notary actually is required. The mechanics lien form builder lays out every field above, including the verification.
Get the amount right. The lien is for the lesser of the reasonable value of your work or the agreed price (§ 8430). An honest mistake in the figure does not void the claim, but § 8422 voids it for intent to defraud and forfeits it outright if you willfully include work you did not furnish to that property. Leave disputed extras out unless you can prove them.
Upon the recording of the enclosed MECHANICS LIEN with the county recorder's office of the county where the property is located, your property is subject to the filing of a legal action seeking a court-ordered foreclosure sale of the real property on which the lien has been recorded. That legal action must be filed with the court no later than 90 days after the date the mechanics lien is recorded.
Lien deadline
A copy of the claim, with the Notice of Mechanics Lien, must be served on the owner by registered, certified or first-class mail with a certificate of mailing, to the owner's home or business address or the address on the building permit. If that fails, mail it to the construction lender or the original contractor. Skip this and the lien is unenforceable as a matter of law (§ 8416(e)). Service is complete the day you mail it.
Suit within 90 days, and releasing an expired lien
A recorded claim lasts 90 days. If you have not filed an action to enforce it by then, § 8460(a) says it expires and is unenforceable. The only extension is a recorded agreement with the owner to extend credit: then suit is due 90 days after the credit runs out, and never later than one year after completion. Diarise the suit date the day you record, and send the file to counsel a month ahead.
An owner, general or sub that disputes your lien can also take the property out from under it. Recording a lien release bond of 125 percent of the claim releases the property, and your claim moves to the bond. You then have six months after notice of the bond to sue on it (§ 8424).
A lien you let expire is not harmless. Under § 8482 the owner can demand in writing that you release it, wait 10 days, then petition the court for a release order (§ 8480). The hearing is set within 30 days of filing, and the prevailing party gets reasonable attorney's fees (§§ 8486, 8488). If you were paid, or the 90 days passed, record a release yourself. The lien release form generator drafts it.
The four statutory waiver forms
California prints its lien waivers in the Civil Code. A waiver and release given to get paid is null, void and unenforceable unless it is in substantially the statutory form, and each form waives lien, stop payment notice and payment bond rights together. A custom waiver drafted by the general's lawyer does not count.
| Form | Cite | Sign it | Exceptions the form keeps |
|---|---|---|---|
| Conditional waiver and release on progress payment | § 8132 | With the pay app, before the check | Retentions, unpaid extras, earlier unpaid conditional waivers, contract rights |
| Unconditional waiver and release on progress payment | § 8134 | After the progress check clears | Retentions, unpaid extras, contract rights |
| Conditional waiver and release on final payment | § 8136 | Before the final check | Disputed claims for extras, by amount |
| Unconditional waiver and release on final payment | § 8138 | After the final check clears | Disputed claims for extras, by amount |
A conditional waiver takes effect only on proof of payment: your endorsement on a check the bank has paid, or your written acknowledgment (§ 8124). That is why it is safe to hand over with the pay application. The unconditional forms carry a warning, in type at least as large as the rest of the form, that they bind you even if you have not been paid. Use the conditional lien waiver generator until the money clears, and read conditional vs unconditional if a general is pushing for the other one.
The stop payment notice
A lien attaches to the land. A stop payment notice attaches to the money: it tells the owner or the construction lender to hold back enough of the construction funds to cover your claim. On a private job you can use both at once: the lien for leverage over title, the notice to freeze what has not been paid out yet.
- Who. Any lien claimant except the direct contractor may give one to the owner (§ 8520). Any lien claimant, direct contractor included, may give one to the lender (§ 8530).
- When. Only after a preliminary notice, and before your time to record a lien runs out (§ 8508). In the worked example, by September 11.
- What. Signed and verified, describing the work and its total value, and claiming only work done through the date of the notice (§ 8502). A willfully false one forfeits your lien (§ 8504).
- Bond. A lender may decline to withhold on an unbonded notice (§ 8536). A bonded one carries a bond of 125 percent of the claim (§ 8532).
- Suit. No sooner than 10 days after giving it, and no later than 90 days after the time to give it expires (§ 8550). In the example, December 10.
Owner's demand
An owner can send you a written demand to give it a stop payment notice. Ignore it, and § 8520(b) says you forfeit your lien. Answer every such demand in writing, with a notice.
The stop payment notice generator drafts a California notice with the fields above. If you are deciding between this and a bond claim, the lien vs payment bond comparison sets them side by side.
Questions
Does a California mechanics lien have to be notarized?
No. The claim must be signed and verified by the claimant, and Civil Code § 8416(b) makes the recorder accept a claim in proper form without an acknowledgment.
Can I record a lien before my work is finished?
No. A subcontractor or supplier records after it stops providing work (§ 8414), and a direct contractor records after it completes its direct contract (§ 8412).
I missed the 20-day preliminary notice. Is my lien gone?
Not all of it. Serve the notice now. Under § 8204 it protects work done in the 20 days before you served it and everything after.
The owner never sent me the notice of completion. What is my deadline?
If you served a preliminary notice and the owner is not an exempt owner-occupant of a home with four or fewer units, an unsent notice does not shorten your time (§ 8190). Your outside limit is then 90 days after completion. Record earlier anyway.
How long does a recorded California lien last?
90 days from recording, unless you file suit to enforce it or record an agreement with the owner extending credit (§ 8460).
