Florida Mechanics Lien Deadline: The 90-Day Rule and the NTO Trap

One note before we start: Florida officially calls this a construction lien, not a mechanics lien — it's Part I of Chapter 713, titled "Construction Liens." Everyone in the trades still says "mechanics lien" half the time, and you'll see both names on this page. Same tool. (Here's why there are two names.)

Deadline 1: The 45-day Notice to Owner (the trap)

The Notice to Owner — the NTO — is the piece of paper that ends more Florida lien claims than any other. It's a short notice you send at the start of the job, and its only job is to tell the property owner: I'm working on your project, here's what I'm doing, and I have lien rights if I don't get paid.

Who has to send it: everyone who doesn't have a direct contract with the owner. Subcontractors, sub-subcontractors, material suppliers, equipment lessors — that's you. General contractors in direct contract with the owner don't need one (the owner already knows who they are). The statute carves out laborers, but if you're a laborer, sending one anyway is cheap insurance.

Who gets it: the owner, first and always. Then it branches by how far down the chain you sit:

• Subcontractor / supplier to the GC: serve the owner.
• Sub-subcontractor, or a materialman selling to a subcontractor: serve the owner and a copy on the general contractor.
• Materialman selling to a sub-subcontractor: serve the owner, a copy on the GC, and the notice itself on the subcontractor too if you know their name and address.
• Anyone the owner named in the Notice of Commencement as an additional recipient (like the lender): send them a copy as well.

When: before you start, or no later than 45 days after you start furnishing labor, services, or materials (§ 713.06(2)(a)). And here's the part people learn the hard way: the smart move is to send it the day you start. There is no prize for waiting, and "I was going to send it next week" has killed more liens than any legal technicality.

What goes in it: your name and address, a description of the property good enough to identify it, and the nature of the labor, services, or materials you're furnishing or will furnish. The statute also requires a specific warning to the owner — the "WARNING TO OWNER" language about the owner possibly paying twice. Use a proper Florida NTO form (there's one in our free templates) rather than drafting it from memory.

What it is NOT: a lien. The statute says so explicitly — the NTO "is not a lien, cloud, or encumbrance on the real property." It doesn't show up on title. It doesn't scare anyone. Owners in Florida see these every day; it's routine paperwork, not a threat. The contractors who treat the NTO like an act of war are the ones who skip it and lose everything later.

What happens if you miss it: the statute is blunt — failure to serve the notice on time "is a complete defense to enforcement of a lien by any person." That's lawyer for you have no lien, end of story. You can still sue for breach of contract, but the property itself is off the table.

Two timing details worth knowing. First, if you're supplying specially fabricated materials — custom trusses, specialty millwork, anything made to order — your 45 days can start running when fabrication starts, not when the truck shows up at the site. Second: don't cut the 45 days close arguing about whether "mailed by day 45" counts. Mail it early, get proof of mailing, and never let a deadline turn into a debate.

Deadline 2: Record the Claim of Lien within 90 days

This is the big one — the actual lien. If the NTO was you raising your hand, the Claim of Lien is you putting your claim on the property's public record.

The rule: record your Claim of Lien in the clerk's office of the county where the property sits, no later than 90 days after your final furnishing of labor, services, or materials (§ 713.08(5)). "Final furnishing" means the last day you furnished work — not the last day anyone worked on the project. If the painters are still there for another month after you finished the rough-in, their schedule doesn't extend your deadline.

A few wrinkles in the 90-day rule:

• Multiple counties: if the property sits in two or more counties, record in each one.
• Rental equipment: there's a special version of the rule for rented equipment — roughly 90 days from when the equipment was last on the job site available for use. If you're an equipment lessor, confirm the details with a Florida attorney rather than assuming the standard rule.
• Contract terminated early: if the original contract is terminated, your 90 days runs from the termination date or your final furnishing, whichever comes first.
• You can record during the job, not just after. The claim "may be recorded at any time during the progress of the work or thereafter" — you don't have to wait until everything goes sideways. Most people wait because recording feels aggressive. It isn't; it's paperwork.

What goes in the claim: the statute requires specific contents — your name and address, a description of the property, the nature of what you furnished, the amount you're claiming, the dates of your first and last furnishing, and who hired you, among other details. Get the amount right: claim what's actually owed, don't pad it, and remember the claim is a sworn statement. A form built for Florida's statute (like the ones in our free templates) keeps you from leaving a required field blank.

Deadline 3: Serve the recorded lien within 15 days

Recording the lien isn't the finish line — you also have to serve a copy of the recorded claim on the owner, either before recording or within 15 days after recording (§ 713.08(4)(c)). Serve it the way the statute requires (see § 713.18 for the service methods) and keep your proof.

Miss this one and the lien becomes voidable — meaning the owner can get it thrown out to the extent your delay prejudiced them. It's not the automatic death sentence that missing the NTO is, but it's a completely avoidable wound. Record the lien, then put the copy in the mail the same day. Done.

What counts as your "last day of work"

The entire 90-day clock hangs on one date: your final furnishing. And this is where good contractors talk themselves into missing the deadline, because the date is sneakier than it looks.

Florida courts use a four-part test for what counts as real, deadline-extending work: it has to be done (1) in good faith, (2) within a reasonable time, (3) pursuant to the terms of the contract, and (4) necessary to finish the job. Work that fails that test doesn't move your deadline a single day.

In practice, that means:

• Punch-list trips don't count. Going back to touch up paint or tighten a fixture doesn't restart your 90 days.
• Warranty and repair work doesn't count. Fixing something under warranty months later is not "final furnishing." The statute specifically excludes correcting deficiencies in work you already performed.
• The certificate of occupancy doesn't matter. Your deadline is measured from your last day of furnishing — not from when the CO was issued, not from substantial completion, not from when the owner moved in.
• The project's end date doesn't matter either. If you were an early-trade sub on a two-year project, your 90 days started when you finished — possibly a year before the project wrapped. Waiting for the ribbon-cutting to file your lien is how early trades lose everything.

The Florida Bar's own journal on the state's lien law puts it plainly: the final furnishing date is the last day you actually contributed to the improvement — and punch-list, warranty, and repair work don't count. When you're anywhere near the 90-day mark, count from your last real day of contract work, and file early rather than arguing about it later.

The 1-year enforcement window

You recorded on time. Now you have one year from the recording date to file a lawsuit to foreclose the lien (§ 713.22). File the suit and the lien survives; don't, and it dies on its own at the one-year mark.

Three things that can shrink or complicate that year:

• Notice of Contest of Lien. The owner (or the owner's attorney) can record a Notice of Contest, which cuts your one year down to 60 days from service of the notice. If you get one of these and don't sue within 60 days, your lien "shall be extinguished automatically." Treat a Notice of Contest like a fire alarm.
• Lis pendens. Once you file suit, record a notice of lis pendens. Without it, your lien — even with a lawsuit pending — isn't enforceable against later buyers or creditors who didn't know about it.
• Contractor's Final Affidavit. If you're the general contractor in direct contract with the owner, you generally must serve a Contractor's Final Affidavit on the owner at least 5 days before filing your foreclosure lawsuit, confirming that everyone below you has been paid. Skip it and your suit can stall before it starts.

If you already missed one

First: don't fake it. Backdating a Notice to Owner or inventing a later "last day of work" will turn a lost lien into fraud, and judges have zero patience for it.

Second: a dead lien isn't always a dead claim. Missing the NTO kills your lien, but you can still sue the person who hired you for breach of contract. You lose the property as leverage — no cloud on title, no foreclosure threat — but the debt itself doesn't disappear. Talk to a Florida construction attorney about what's still on the table; sometimes a demand letter referencing the next job's NTO gets more attention than you'd expect.

Third: fix the system, not just the symptom. Almost every blown Florida deadline traces back to the same root cause — nobody diaried the 45-day NTO at the start of the job. Make the NTO part of your job-start checklist, right next to the contract and the insurance cert. The contractors who never miss deadlines aren't smarter; they just send the notice on day one, every time.

Yes, Florida officially calls it a "construction lien"

You'll notice this guide says "mechanics lien" in the headline but Florida's statute says "construction lien." That's not a mistake — it's the same device under the state's official name (Chapter 713, Part I: "Construction Liens"). Florida is one of a handful of states that modernized the label; most states still say "mechanics lien."
