Mechanics Lien for Contractors: Basics and Deadlines

What a mechanics lien does, who needs a preliminary notice, how to file one, and the real recording, service and enforcement deadlines in four example states.

A mechanics lien for contractors, in short, is a claim recorded against the property you improved, so the owner can't easily sell or refinance until you're paid. The deadlines are strict and set by each state: a California direct contractor records within 90 days of completion, Florida allows 90 days from final furnishing, and Texas residential jobs run to the 15th day of the third month after completion.

Liens are the strongest tool a small contractor has against a customer who won't pay, and the easiest to lose on a technicality. Miss a notice or a day and the lien is void, however good the work was. This guide explains how liens work, then sets out the deadlines in California, Texas, Florida and New York straight from each state's statute, so you can see how much they differ. It's general information, not legal advice: read your own state's law, and talk to a construction attorney before you record a lien on a large job. If you haven't sent reminders and a demand letter yet, start with how to collect unpaid invoices.

Key takeaways

A lien secures the debt against the property; it isn't payment. You still have to enforce it in court before it expires.
Clocks start at completion or last work, not at your invoice date.
Notices come first in many states. Subcontractors and suppliers usually must send a preliminary notice early in the job.
Enforcement windows are short: 90 days after recording in California, one year in Florida and New York.
Homeowners get extra protection: Texas homestead liens need a written contract signed before work starts.
Claim only what you're owed, after credits and offsets.

What is a mechanics lien?

A mechanics lien is a legal claim against real property, recorded by someone who supplied labor or materials to improve it and wasn't paid. Once recorded at the county, it shows up on the title. California requires the lien notice sent to owners to warn that the claimant may seek a court-ordered foreclosure sale and that the lien may affect their ability to borrow against, refinance or sell. That is the leverage: an owner who wants to sell, refinance or avoid a foreclosure suit has a strong reason to settle.

A lien doesn't put money in your account by itself. If the owner still doesn't pay, you have to sue to enforce (foreclose) the lien within the state's deadline, or it lapses.

Do you need to send a preliminary notice?

Whether you need a preliminary notice depends on your state and on who hired you: rules aimed at subcontractors and suppliers often don't apply, or apply differently, to a contractor hired directly by the owner.

California: a preliminary notice is due no later than 20 days after the claimant first furnishes work. A claimant who contracted directly with the owner gives it only to the construction lender, if there is one.
Florida: lienors who aren't in privity with the owner (subcontractors, suppliers) must serve a Notice to Owner before, or no later than 45 days after, they start furnishing labor or materials.
Texas: claimants other than the original contractor must send a notice of claim for unpaid labor or materials; on residential projects it's due by the 15th day of the second month after the month the work was provided.

Small residential service shops are usually the direct contractor, so the lien deadline matters more than the notice. If you ever work as a sub for a general contractor or builder, the notice is the step most often missed.

What are the mechanics lien deadlines in each state?

Mechanics lien deadlines differ in what starts the clock, how long you get, and how quickly you must sue. These four examples are for a contractor hired directly by the owner, taken from the statutes in October 2026:

State	Record the lien by	Serve the owner	Sue to enforce within
California (Civ. Code 8412, 8416, 8460)	After completing your contract and before the earlier of 90 days after completion or 60 days after the owner records a notice of completion or cessation	The lien must include a signed proof-of-service affidavit showing it was served on the owner	90 days after recording
Texas (Prop. Code 53.052, 53.055, 53.158)	Residential: 15th day of the third month after the month your work was completed, terminated or abandoned (fourth month for other projects)	Send a copy to the owner within 5 days of filing	One year after the last day you could have filed (extendable to two by recorded agreement)
Florida (Stat. 713.08, 713.22)	90 days after your final furnishing of labor, services or materials	Serve before recording or within 15 days after	One year after recording
New York (Lien Law 10, 11, 17)	8 months after completion or last work; 4 months for a single-family dwelling	Serve within 5 days before or 30 days after filing	One year after filing, with a notice of pendency

Florida adds a step before you can sue: the contractor must give the owner a final payment affidavit at least 5 days before starting an action to enforce the lien. Every state has more detail than a table can hold, including special rules for retainage, terminated contracts and public projects.

How do you file a mechanics lien?

You file a mechanics lien by preparing the claim on your state's required form, signing it, recording it with the county where the property is, and serving the owner. In order:

Find your deadline. Work out the completion or last-work date from your job records and count forward under your state's rule.
Gather the facts. California's list is typical: the amount owed after all credits and offsets, the owner's name, the kind of work, who hired you, a description of the site and your address.
Use the right form and wording. Many states require set notice language; Texas homestead liens must say “NOTICE: THIS IS NOT A LIEN. THIS IS ONLY AN AFFIDAVIT CLAIMING A LIEN.” at the top.
Sign it as required (verified or sworn) and record it with the county recorder or clerk.
Serve the owner within the state's window and keep proof of how and when.
Calendar the enforcement deadline the day you record, and decide well before it whether you'll sue.
Release the lien promptly once you're paid.

What protections do homeowners have?

Homeowners get extra protections that a residential contractor has to plan for before the job starts, not after the customer stops paying:

Texas homesteads: to fix a lien on a homestead, you and the owner must sign a written contract before any labor or materials are furnished, both spouses must sign if the owner is married, and the contract must be filed with the county clerk.
Florida disclosure: a direct contract over $2,500 for a one- to four-unit dwelling must include the state's construction lien notice in bold capitals, signed and dated by the owner. Leaving it out doesn't bar a lien against an owner who wasn't harmed by the omission, but it's an easy argument to hand away.
California's warning: the lien itself must carry a notice telling the owner about the 90-day foreclosure deadline and pointing them to the Contractors State License Board.

Because these steps belong in your quote and contract, build them into your paperwork now. Our contractor payment terms, contractor invoice checklist and deposit guide cover the rest of the documents that keep you paid.

Is a mechanics lien worth it on a small job?

A mechanics lien is usually worth it when the debt is in the thousands and the property has equity; on a few-hundred-dollar repair, recording, serving and possibly suing usually cost more than they recover. For small balances, a demand letter and small claims court are often more practical. Note that a Texas justice court can't hear a suit to enforce a lien on land, so a Texas lien foreclosure goes to a higher court.

Where CrewRobin fits

CrewRobin doesn't prepare or record liens. What it does give you is the record a lien depends on: technicians tap Start and Complete on each job in My day and add photos and notes, and each customer record holds the signed quote, the invoice and every text. That makes the completion date and the amount owed easy to prove. Taking a deposit when a quote is approved also shrinks what you'd ever need a lien for. See how it works for roofers and plumbers.

Frequently asked questions

How long do I have to file a mechanics lien?

It depends on the state. A California direct contractor has until the earlier of 90 days after completion or 60 days after a recorded notice of completion; Florida allows 90 days after final furnishing; Texas residential jobs run to the 15th day of the third month after completion; New York allows 4 months for a single-family home and 8 months otherwise.

What is a preliminary notice?

It's an early notice, sent near the start of the job, telling the owner (and often the lender and general contractor) that you're supplying work and may claim a lien. In California it's due within 20 days of first furnishing work; Florida's Notice to Owner is due within 45 days for those not hired directly by the owner.

Can a contractor put a lien on a house without a contract?

Sometimes: Florida's lien law expressly covers oral and implied contracts. But Texas homestead liens require a written contract signed before work starts and filed with the county clerk, and a Florida direct contract over $2,500 on a home needs a lien notice. Check your state's rule before relying on a handshake.

Does a mechanics lien expire?

Yes. If you don't sue to enforce it in time, it lapses: 90 days after recording in California, one year after recording in Florida, one year after filing in New York, and in Texas one year after the last day you could have filed.

Do I need a lawyer to file a mechanics lien?

Not always, but a mistake in the amount, the description or the timing can cost you the lien. For large debts, or before suing to enforce, an hour with a construction attorney is worth it.
