Ninety days, unless the owner takes them back: the California lien dates you do not get told about

Everybody in California construction knows the number 90. Ninety days after the job is complete to record a mechanics lien, and you have three months of runway to work the payment problem out like adults.

That number is right until the owner records one document at the county recorder, at which point it becomes 60 for a direct contractor and 30 for everybody else, and nothing lands in your inbox to tell you it happened. The people who lose California liens rarely miss 90 days. They miss 30, because they were counting to 90.

This page is the fork, the dates it produces, the notice you have to serve with the lien or the whole thing fails, and a worked example with real dates so you can see how fast the short version moves.

The default: 90 days from completion

Two sections carry the base rule, and they say the same thing for different people.

A direct contractor, meaning the one who signed with the owner, records within 90 days after completion of the work of improvement under Civ. Code s.8412. A subcontractor, sub-sub, material supplier or equipment lessor records within 90 days after that same completion under Civ. Code s.8414.

Note what the clock does not run from. Not your last day on site. Not your final invoice. Not the day the general contractor told you the job was finished. Completion of the work of improvement is a property level event, and under Civ. Code s.8180 it happens on the earliest of actual completion of the work, occupation or use by the owner accompanied by a cessation of labor, a cessation of labor for a continuous period of 60 days, or the recording of a notice of cessation after labor has stopped for 30 days.

Which means a job that dies quietly still completes. A general contractor who walks off in March starts a 60 day cessation clock, and the subs who assumed the job was merely paused watch their lien window open and close while they wait for a call about a restart that never comes.

The document that takes your days back

Under Civ. Code Part 6 the owner may record a notice of completion within 15 days of completion. It is one page, it costs almost nothing, and recording it does this:

A subcontractor goes from three months to one month on the strength of a filing they were not part of and did not see. Owners and their lenders know this, which is why the notice of completion is standard practice on financed work and why it usually gets recorded the same week the punch list closes.

Nobody phones you about it. There is no letter, no email, no line in the closeout package. The reliable way to find out is to check the county recorder for the property yourself, once, in the week after your last day on site, and then again two weeks later. That is two searches on a public database, and it is the difference between a deadline you know and a deadline you assume.

Serving your preliminary notice is what puts your name, your address and your scope in front of the owner and the lender in the first place, which is the only reason anyone in that chain would think to keep you informed at all. If you did not serve one, the 20 day rule and the reach-back that softens it are covered in the California preliminary notice, and it is worth reading before you count anything on this page, because a lien recorded without notice rights behind it is a lien with a hole in it.

Worked example: one job, four calendars

Take a private job. Actual completion on 12 May 2026. Watch what the same facts produce in four different worlds.

One recording on 22 May, ten days after the last day of work, and a subcontractor's window shuts on 21 June instead of 10 August. Seven weeks vanish. If that sub sends a final invoice at the end of May, waits the customary 30 days for it to go unpaid, and then starts thinking about remedies in early July, they are already too late and they have not yet done anything wrong by ordinary commercial standards.

Now carry it forward. Say the sub is paying attention and records the lien on 19 June 2026. Under Civ. Code s.8460 they have 90 days from recording to bring suit to foreclose, which lands on 17 September 2026. Miss that and the lien expires on its own, whatever its merits were.

Three dates, one input, and the input is a public record you can check in five minutes. The California lien deadline calculator runs the whole chain from a completion date and a notice of completion date, so a company with a dozen live jobs gets a dozen clean sets of dates instead of one recollection.

The 90 days after recording are not a rest period

Civ. Code s.8460 gives you 90 days from the date you record the lien to file an action to foreclose it. That period does not stretch because settlement talks are going well, and it does not stretch because the owner asked you to be patient while they sort out the general contractor.

Two things are worth knowing about it.

First, if you file, record a notice of pendency of the action within 20 days of commencing it under Civ. Code s.8461. That is the recording that keeps the lien visible on title while the case runs, and it is a short window sitting inside a period when everyone assumes the urgent part is over.

Second, the credit extension in Civ. Code s.8460 is a real negotiating instrument rather than a technicality. Where you and the owner agree to extend credit and notice of that extension is recorded, the lien stays alive past the original 90 days, subject to the outer limit the section sets. An owner who genuinely needs time has a reason to sign it, and you keep your security while the conversation happens instead of choosing between suing a customer you like and losing your claim.

Most liens never get near a courthouse. A recorded lien shows on title, stops a sale, snags a refinance and produces returned calls from people who had stopped returning them. It settles because it is inconvenient, not because it goes to judgment. Working a quiet payer through the stages before that point is the subject of what to do when a California client will not pay.

The notice you serve with the lien, or the lien is worth nothing

This is the one that ends otherwise perfect claims.

Under Civ. Code s.8416 the claim of lien has to include a Notice of Mechanics Lien in the form the section prescribes, and that notice has to be served on the owner or reputed owner. Failure to serve it makes the lien unenforceable as a matter of law. Not weaker. Not challengeable. Unenforceable, on a claim that was filed on time and for the right amount.

So the recording is two acts, not one:

1. Record the claim of lien with the county recorder in the county where the property sits, inside the s.8412 or s.8414 window, with the demand after credits and offsets, the owner or reputed owner's name, a general statement of the work you did, the name of the person who hired you, and a site description good enough to identify the property.
2. Serve the Notice of Mechanics Lien on the owner, and attach the proof of service affidavit to the lien.

Do them together, on the same afternoon, with the proof of service in the same folder as the recorded copy. The two act structure is exactly why this gets dropped: the recording feels like the finish line, and the notice is a five minute step on the far side of it, at the end of a sequence that already took three months.

Retention, stop payment notices and the clocks running next to this one

The lien is not the only date on the job, and on most California jobs it is not even the first one to matter.

Retention on private work is released by the owner 45 days after completion under Civ. Code s.8812, and a direct contractor holding it has to pass a subcontractor's share down within 10 days of receipt under Civ. Code s.8814. That is money with its own timetable, walked through in California retention and release.

The stop payment notice runs on the lien clock on private work under Civ. Code Part 6, and it goes after undisbursed construction funds rather than the property, which is often the faster and cleaner way to get paid on a financed job. The mechanics are in stop payment notices in California.

Public work is a different set of dates entirely. A payment bond is required on public work over $25,000 under Civ. Code s.9550, and suit on that bond runs on a six month clock under Civ. Code s.9558.

And the document that quietly undoes all of it is a release you signed without reading. California prescribes four statutory forms across conditional, unconditional, progress and final, and a form that is not one of them is not effective. Unconditional releases carry a mandatory warning at full type size for a reason. California lien releases and waivers covers which of the four to sign and when.

Put the completion date in the file before you need it

Every date on this page runs off two facts: when completion happened, and whether the owner recorded a notice of completion. Neither is a legal judgment. One is a date on your own schedule and the other is a public record.

A contractor who writes down the last day on site, checks the recorder twice in the following month, and diaries the resulting deadline is holding a calendar that the person avoiding their calls does not have. The rest of it is filling in a form and driving to the recorder's office.

On AEC Stack there is no monthly subscription. The platform fee is 2.5 percent of each invoice processed through the platform, so the tracking earns its keep on the jobs that actually get paid.

Take the job you are most worried about, put its completion date into the California lien deadline calculator, and see how much of your window is left with and without a notice of completion. If the gap between those two answers makes you uncomfortable, open a working business file and get the completion dates on the rest of your jobs recorded before one of them turns into this.
