Florida Construction Lien Deadlines: The 45-Day Notice to Owner and the 90-Day Claim Window

Florida calls it a construction lien, not a mechanics lien, and the terminology difference is the first signal that the framework has its own shape. Florida's deadline structure rests on two hard numbers: the Notice to Owner that most claimants who lack a direct contract with the owner must serve within 45 days of first furnishing labor, services, or materials, and the Claim of Lien that every claimant must record within 90 days of last furnishing. Both are mandatory, and a late or missing Notice to Owner is, by statute, a complete defense to enforcement of the entire lien.

The governing law is the Florida Construction Lien Law, Chapter 713, Part I of the Florida Statutes. Florida courts treat its requirements as strict — the lien is a creature of statute, and a claimant who misses a procedural step does not get equitable relief from it. Florida also overlays an owner-side document, the Notice of Commencement, that interacts with the claimant's deadlines. This guide covers private construction liens; verify the current text of Chapter 713 before relying on any specific deadline.

Who Can Claim a Lien

Chapter 713 extends lien rights broadly, but the Notice to Owner requirement turns on whether the claimant is in direct contract with the owner:

The dividing line is privity with the owner. Anyone not in direct contract with the owner is, in Florida's terms, a lienor not in privity — and that claimant must serve the Notice to Owner to preserve any lien right at all.

The 45-Day Notice to Owner

The Notice to Owner is Florida's preliminary notice, and it is the deadline that destroys the most lien rights. A lienor not in privity with the owner must serve the Notice to Owner before commencing — or not later than 45 days after first commencing — to furnish labor, services, or materials to the project. The notice tells the owner that someone they did not contract with is on the job and may claim a lien if not paid, giving the owner the chance to manage payments down the chain.

The 45 days runs from first furnishing, not from last furnishing or from non-payment. That is the trap. A subcontractor who waits to see whether payment problems develop has usually already missed the window — the clock started the first day materials or labor hit the job. The notice must be served on the owner (and, where applicable, on the contractor and the lender identified in the Notice of Commencement) by a statutorily permitted method, typically certified or registered mail with proof of service, or actual delivery.

The 90-Day Claim of Lien Deadline

The core payload is the Claim of Lien. Every lienor — whether or not in privity, whether or not a Notice to Owner was required — must record a Claim of Lien within 90 days after the final furnishing of labor, services, or materials to the project. The 90 days is a hard deadline; a Claim of Lien recorded after it is invalid regardless of the merit of the underlying debt.

What counts as final furnishing matters. Florida courts have generally held that punch list work, warranty or correction work, and minor remedial visits do not extend the final-furnishing date — the 90 days runs from the last substantive contract work, not from a trivial return trip. A claimant who assumes a late callback reset the clock can record a Claim of Lien that is, in fact, weeks late. Serving the Notice to Owner does not dispense with recording the Claim of Lien; both steps are independently required.

The Claim of Lien must also be served on the owner — generally within 15 days of recording — and recording without that service can defeat the lien. Treat service of the recorded claim as part of the recording task.

Where to File

The Claim of Lien is recorded in the official records of the clerk of the circuit court in the county where the property is located. The claim must contain the statutorily required content: the lienor's name and address; the labor, services, or materials furnished and the contract price or value; a description of the property sufficient for identification; the name of the owner; the name of the person with whom the lienor contracted; the dates of first and last furnishing; and the amount unpaid.

The owner's Notice of Commencement, recorded before work begins, identifies the owner, contractor, lender, and a designated party for service of notices. A lienor should obtain a copy early — it supplies the correct addresses for serving the Notice to Owner and confirms how long the owner's permit-side window runs.

Lien Priority

Florida construction lien priority generally relates back to the recording of the Notice of Commencement. All liens for the improvement described in a given Notice of Commencement take priority as of its recording date, which means a properly recorded Notice of Commencement that predates a mortgage can subordinate that mortgage to the construction liens.

This is why Florida construction lenders are careful to record their mortgage before the Notice of Commencement is recorded and before visible work begins. If no Notice of Commencement was recorded, or if it expired, priority questions become more fact-intensive — another reason to pull the Notice of Commencement at the start of a job.

Transfer to Bond and the Owner's Notice of Contest

Florida gives the owner (or a contractor or other interested party) two important tools that change the claimant's timeline. The first is transfer to bond: the lien can be transferred off the real property to a statutory bond or a cash deposit. The lien then attaches to the security instead of the land, which clears title for a sale or refinance while preserving the claimant's right to pursue the bond.

The second, and the one that shortens deadlines, is the Notice of Contest of Lien. When the owner records a Notice of Contest and it is served on the lienor, the lienor's window to file a foreclosure suit collapses from one year to 60 days from the date of the Notice of Contest. A claimant who ignores a Notice of Contest on the assumption that the full year still applies can lose the lien by inaction. A related summons-to-show-cause procedure can compress the window even further.

Enforcing the Lien

Recording the Claim of Lien perfects the lien; it does not collect. To enforce, the lienor must file an action to foreclose the lien within one year of the date the Claim of Lien was recorded. If suit is not filed within that year — or within the shortened 60-day window after a Notice of Contest — the Claim of Lien is subject to dismissal and the lien is lost.

A foreclosure action proceeds in the circuit court and, if the lienor prevails, results in a judgment and judicial sale of the property with proceeds distributed by priority. As elsewhere, most Florida lien claims resolve through payment to clear title rather than at a sale — the lien's value is in making the property difficult to transact. Florida's lien statute also has a prevailing-party attorney's fee provision, which cuts both ways and is a real consideration before filing.

Lien Waivers

Florida prescribes statutory lien-waiver forms. Chapter 713 sets out separate waiver and release forms for progress payments and for final payment, and the law was structured so that a lienor cannot be forced to sign a broader release than the statutory form provides — the forms exist to keep a payment-related waiver from sweeping in other contract rights.

A lienor can agree to use a different form, but cannot be compelled to. The practical discipline is the familiar one: a final or unconditional waiver should be exchanged only against cleared funds, because it releases lien rights on its face. A waiver that purports to release lien rights for money not yet received puts the claimant ahead of its own payment. Use the statutory progress-payment form for interim draws and reserve the final waiver for actual final payment.

Practical Timing Strategy

For a Florida subcontractor or supplier not in privity with the owner, the workable sequence is:

Bottom Line

Florida's Construction Lien Law (Chapter 713) runs on two hard deadlines: the Notice to Owner that a lienor not in privity must serve within 45 days of first furnishing, and the Claim of Lien that every lienor must record within 90 days of final furnishing. A late or missing Notice to Owner is a complete statutory defense to the whole lien. Priority generally relates back to the recorded Notice of Commencement, the lien can be transferred to a bond, and an owner's Notice of Contest shortens the one-year foreclosure window to 60 days. Lien waivers should track the statutory progress and final forms. Because the deadlines are strict and an owner's Notice of Contest can compress them without warning, verify the current Chapter 713 requirements against the project's facts. For significant claims, the strict construction Florida applies makes experienced Florida construction counsel a worthwhile investment.
