Florida Mechanics Lien: Filing Requirements, Deadlines, and Process (2026)
Florida subcontractors, sub-subcontractors, and material suppliers must serve a Notice to Owner (NTO) on the property owner before they can file a mechanics lien, under Fla. Stat. § 713.06(2)(c). The NTO must be served no later than 45 days after first furnishing labor or materials to the project. Subcontractors working directly for the general contractor are required to serve this notice; only those with a direct contract with the owner are exempt. A valid lien itself must then be recorded in the county where the property is located no later than 90 days after the last day of furnishing. Failing to serve the NTO on time is a complete bar to lien rights — no workaround, no exception.
Who Must Serve a Notice to Owner in Florida?
Any party without a direct contract with the property owner must serve a Notice to Owner to preserve lien rights. Under Fla. Stat. § 713.06, this means subcontractors, sub-subcontractors, material suppliers, and equipment lessors who contract with the general contractor — not the owner — are all required to serve the NTO. General contractors with a direct contract with the owner are not required to serve an NTO, but they must record a Notice of Commencement and comply with separate notice obligations before demanding final payment.
If you're a second-tier sub — meaning you contracted with a subcontractor, not the GC — you also need to serve the NTO, and you must serve it on both the owner and the GC. Skipping either party voids the notice.
What Is the Deadline to Serve the Florida Notice to Owner?
The NTO must be served no later than 45 days after you first furnish labor, services, or materials to the project. That 45-day clock starts on the date you physically deliver materials or perform work on-site — not the contract date, not the invoice date, not when the PO was issued. Under Fla. Stat. § 713.06(2)(c), if you miss this deadline, you lose lien rights entirely on work performed before the late notice. Work performed after a late notice is still partially protected, but the window before that 45-day mark is gone.
Practically speaking, the safest move is to serve the NTO the same week you mobilize. Waiting until day 40 to gather paperwork is how contractors lose real money.

What Information Must the Florida Notice to Owner Include?
The NTO must contain specific information required by Fla. Stat. § 713.06(2)(a). A defective notice can be challenged and invalidated, so every field matters:
- Name and address of the lienor (the subcontractor or supplier serving notice)
- Name and address of the person who contracted with the lienor (typically the GC)
- Description of the services or materials being furnished
- Name and address of the owner as shown on the Notice of Commencement
- Legal description of the property as listed on the Notice of Commencement
- Name and address of the contractor if different from who contracted with you
The property description and owner information must match the Notice of Commencement recorded in the county records. Before you draft the NTO, pull the Notice of Commencement from the county — it's a public record and is the controlling document for who gets served and where.
How Must the Florida Notice to Owner Be Served?
Under Fla. Stat. § 713.06(2)(c), the NTO must be served by:
- USPS Certified Mail with Return Receipt (recommended — creates a documented proof of delivery)
- Personal delivery with a signed acknowledgment
- Overnight express delivery with evidence of delivery
Certified Mail is the standard in practice because it generates a paper trail: the tracking number, the delivery scan, and the Return Receipt card all serve as evidence that the owner received the notice. If a dispute ever goes to court, "I mailed it" without documentation is not enough. USPS Certified Mail costs $4.85 as the base service fee in 2026, plus standard postage — a minor cost compared to what's at stake on any subcontract.
What Is the Deadline to File the Florida Mechanics Lien Itself?
After serving the NTO, the mechanics lien must be recorded in the clerk of court's office in the county where the property is located. The deadline is 90 days after the last day you furnished labor, services, or materials to the project, per Fla. Stat. § 713.08(5). "Last day of furnishing" means the last day you actually worked or delivered materials — not the last day you were supposed to work, not the date the contract ended, and not a return trip to pick up equipment.
After the lien is recorded, you must then serve a copy of the recorded lien on the owner within 15 days of recording. This is a separate service requirement and is mandatory under Fla. Stat. § 713.08(4)(c). A lien recorded on time but not served on the owner within 15 days is unenforceable.
What Must the Florida Mechanics Lien Contain?
The lien document itself must meet the requirements of Fla. Stat. § 713.08. Required elements include:
- Lienor's name and address
- Description of real property (legal description sufficient to identify it)
- Owner's name as it appears on the Notice of Commencement
- Amount claimed — unpaid contract balance, extras approved in writing, retainage
- Name of the person who contracted with the lienor
- First and last dates of furnishing labor or materials
- Statement that the lien is true and correct signed and notarized by the lienor or an authorized officer
The lien must be notarized — no exceptions. Unnotarized liens are invalid under Florida law. After notarization, the lien is recorded with the clerk of court in the county where the property sits. Recording fees vary by county but are typically in the $10–$15 range per page.
How Long Do You Have to Enforce a Florida Mechanics Lien?
Recording a lien does not win you the money — it just secures your position. You must enforce the lien by filing a lawsuit within 1 year of recording, per Fla. Stat. § 713.22(1). If you do not file suit within that year, the lien expires and becomes unenforceable.
That said, Florida law also allows the property owner to force the issue sooner. If an owner serves a lienor with a "Notice of Contest of Lien," the lienor has only 60 days from receipt of that notice to file suit, regardless of how much time is left on the one-year clock. Ignoring a Notice of Contest of Lien is one of the most common ways subcontractors lose lien rights after successfully recording a valid lien.
Does Florida Require a Preliminary Notice for Public Projects?
Florida public construction projects — work performed on government-owned property — are governed by a separate statute, Fla. Stat. § 255.05 (the "Public Works Bond" statute). Mechanics liens cannot be filed against public property in Florida. Instead, the payment remedy is a claim against the payment bond that the general contractor is required to post on public projects over $200,000.
To preserve bond claim rights, a subcontractor must provide written notice to the GC within 90 days of last furnishing labor or materials. This notice requirement is separate from the NTO process that applies to private projects. If you're on a public job, confirm whether a payment bond was recorded and make sure your written notice goes to the GC and bonding company within the 90-day window.
How Bad Is the Florida Payment Problem?
Florida's construction payment issues are not unique, but they're significant. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. Slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending.
Mechanics lien rights exist precisely because of this dynamic. The NTO is not paperwork for its own sake — it is the legal mechanism that puts the property owner on notice that you have a financial stake in the project. An owner who pays the GC without confirming subcontractors are paid can be left with a liened property. That reality is what gives the NTO its leverage.
Frequently Asked Questions
Can I still file a Florida mechanics lien if I forgot to serve the Notice to Owner?
If you missed the 45-day NTO deadline, you cannot file a valid mechanics lien for work performed before that window closed. Work performed after you serve a late NTO may still be protected, but the earlier work is unprotected. There are no grace period provisions or cure mechanisms under Florida lien law for a missed NTO. Your remaining options are breach of contract claims, collections, or small claims court depending on the amount.
Does the Notice to Owner need to be notarized?
No. The Notice to Owner itself does not need to be notarized under Florida law. The mechanics lien, however, must be notarized before recording. The NTO needs to be accurate and served correctly — but notarization is not a requirement for the notice itself.
What happens if the property owner never responded to my Notice to Owner?
The NTO is a one-way notice — it does not require a response from the owner. The purpose is to put the owner on legal notice that you are furnishing labor or materials and have lien rights. As long as you served it correctly and within the 45-day window, your lien rights are preserved regardless of whether the owner acknowledges it.
Does the 90-day lien deadline run from the last day I worked or the last day on the contract?
It runs from the last day you actually furnished labor, services, or materials to the project. If your contract runs through March 31 but you last worked on February 10, the 90-day clock starts February 10. Be careful with "warranty callbacks" or minor punch list visits — a small amount of work performed after a long gap could reset the clock, but Florida courts scrutinize whether that work was substantive or merely a pretext to extend the deadline.
Do I need to serve the Notice to Owner on the construction lender?
Florida's NTO statute under § 713.06 requires service on the owner and, if you are a sub-subcontractor, also on the GC. There is no statutory requirement to serve the NTO on the construction lender. However, if you later need to enforce your lien rights through foreclosure, the lender should be named as a party in the lawsuit since they likely have a recorded mortgage interest in the property.
What is a Notice of Contest of Lien and how does it affect my deadline?
A Notice of Contest of Lien is a document the property owner can record and serve on you after you file a mechanics lien. Under Fla. Stat. § 713.22(2), once you receive this notice, you have only 60 days to file a lawsuit to enforce the lien — down from the standard one-year enforcement window. If you receive this notice, contact a Florida construction attorney immediately and calendar the 60-day deadline that same day.
Can a property owner use a lien waiver to eliminate my lien rights before I'm paid?
A lien waiver signed before payment is received ("conditional" waivers conditioned on payment clearing are enforceable; unconditional waivers signed before payment is received can waive rights you haven't been paid for). Florida courts have generally held that a lien waiver signed before payment is received, in exchange for a promise to pay, can be challenged if payment is never made. Read every lien waiver before signing — conditional language matters.
Is the Florida Notice to Owner the same as a preliminary notice in other states?
Functionally, yes. Florida's NTO serves the same purpose as the 20-day preliminary notice in California or the Notice of Right to Claim a Lien in Washington — it is a pre-lien notice that preserves your ability to record a mechanics lien later if you don't get paid. The name and deadline differ by state (Florida: 45 days; California: 20 days), but the legal function is the same.
