How Long Do You Have to File a Mechanics Lien? Filing Deadlines by State

Quick Answer

Most states give you somewhere between 60 days and 8 months to record a mechanics lien, and 90 days is the most common figure. The number matters less than you'd think, though. What catches people out is the trigger: the event that starts the clock. In some states it's your own last day of work. In others it's the day the whole project was finished, or the day the owner records a notice of completion. Texas counts in months and lands on the 15th. If you get the trigger wrong, you'll calculate the wrong date, and a lien recorded one day late is usually void. Courts almost never excuse it.

The Four Clocks States Use

Every state's filing deadline runs from one of these starting points (a few states use two at once):

1. Your last furnishing. The last day you performed work or delivered materials on the job. Florida, Washington, Michigan, North Carolina and Minnesota use this. It's the most predictable clock because you control the date.
2. Completion of the whole project. The clock starts when the entire improvement is done, whether or not your own work ended months earlier. New York, Pennsylvania and Tennessee lean on completion-based triggers.
3. A recorded notice of completion. In California, Arizona, Nevada and Utah, an owner can record a notice of completion (or cessation). That usually shortens your window a lot, sometimes to 30 days. If you don't watch the county records, you won't know it happened.
4. A calendar-month formula. Texas and Virginia count from the end of a month, not from a specific day. That produces deadlines that look odd but can be calculated exactly.

Mechanics Lien Filing Deadlines: 18-State Reference

These are the recording deadlines for private projects. Public projects generally don't allow liens at all (you'd claim against a payment bond instead). Many states also require preliminary notices or pre-lien notices before this date, so meeting the filing deadline doesn't mean you've done everything else the state requires.

Lien statutes get amended regularly. Texas rewrote its whole schedule in 2022, for example. Always confirm against the current statute or a live deadline tool before relying on any table, including this one.

Worked Example: Same Job, Three Different Deadlines

An HVAC subcontractor finishes rough-in and trim on a commercial office build. The sub's last day on site is May 20. The general contractor's original contract is completed on June 8. The sub is owed $38,400.

• If the job is in Texas: the clock runs from the month the original contract was completed (June). The 4th month after June is October, so the lien must be recorded by October 15. If it were a residential project, the deadline would be the 15th of the 3rd month: September 15.
• If the job is in Florida: the GC's completion date doesn't matter. The sub has 90 days from its own final furnishing on May 20, which makes the deadline August 18, nearly two months before the Texas date.
• If the job is in California and the owner records a notice of completion on June 12: the sub's 90-day window from completion collapses to 30 days after recording, so the deadline is July 12. If the sub's team were only checking a "90 days" rule of thumb, they'd miss it by weeks.

It's the same work and the same invoice, but the deadlines are 95 days apart. That's why a single company-wide "we lien at 90 days" policy doesn't work across state lines.

How to Calculate Your Deadline in 6 Steps

1. Identify the project type. Private commercial, private residential or public. Residential windows are often shorter, and public jobs use bond claims instead of liens.
2. Find your trigger event in the state statute: your last furnishing, project completion, a recorded notice, or a month formula.
3. Write down your true last furnishing date from delivery tickets or daily logs. Don't estimate it from invoices.
4. Check the county records for a notice of completion or cessation if you work in a state where one can shorten your window. Check every couple of weeks as a job winds down.
5. Count calendar days, not business days. Generally you don't count the trigger day itself. Some states roll a weekend or holiday deadline to the next business day, but not all of them do, so don't rely on it.
6. Set your internal deadline 10 business days early. Recorders reject filings for missing legal descriptions, notarization problems or margin rules, and you need room to fix the document and resubmit.

Common Mistakes That Cost Lien Rights

• Treating warranty or punch-list work as your last day. Most states don't restart the clock for corrective, warranty or trivial work done after the job was substantially finished. Florida's statute says so directly. Use your last day of real contract work.
• Waiting on a payment promise. "The check is being cut Friday" doesn't pause anything. If the promise falls through after your deadline, you're left with an unsecured claim.
• Missing a recorded notice of completion. In California, Arizona, Nevada and Utah, the owner doesn't have to tell you personally when one is recorded. You have to watch for it.
• Confusing the filing deadline with the enforcement deadline. Recording the lien is step one. Most states then give you a separate, fixed period to file a foreclosure lawsuit, often 90 days to 2 years after recording. Miss that and the lien expires.
• Skipping required notices. A lien recorded on time can still be invalid if you didn't send the preliminary notice or pre-lien notice your state requires earlier in the job.

Frequently Asked Questions

Can I file a mechanics lien after the deadline if the owner agrees?

No. The deadline is set by statute and parties can't extend it by agreement. A lien recorded late is typically unenforceable even if the owner never objects. The owner, their lender or a title company can have it removed later.

Does a partial payment reset the lien deadline?

No. Filing deadlines run from work or completion events, not from payments. A partial payment reduces the amount you can claim, but it doesn't move your deadline.

Is it better to file early?

Usually yes, as long as your work is finished and you've already sent any required notices. In most states you can't record before you've stopped furnishing. After that, filing well before the deadline costs nothing and protects you if the county rejects the first submission.

What if I supplied materials to more than one phase of the same project?

If the deliveries were all under one continuous contract, most states treat your last delivery as the trigger for the whole account. If the deliveries were under separate contracts or purchase orders with a real gap between them, each one may have its own deadline. When it's unclear, file for the earlier phase before its deadline runs out.
