Florida subcontractors, sub-subcontractors, and material suppliers who do not have a direct contract with the property owner must serve a Notice to Owner (NTO) no later than 45 days after first furnishing labor or materials to the project, under Fla. Stat. § 713.06(2)(c). After that, if you go unpaid, you have 90 days from the last day you furnished labor or materials to record a Claim of Lien in the county where the property is located, under Fla. Stat. § 713.08(5). Missing the NTO deadline does not eliminate your lien rights entirely — it limits protection to work performed in the 45 days before service. Missing the 90-day lien recording deadline is a complete bar to your lien rights with no exceptions.
Who Is Required to File a Mechanics Lien in Florida?
Any contractor, subcontractor, sub-subcontractor, laborer, or material supplier who furnishes labor, services, or materials on a Florida construction project and has not been paid has the right to file a mechanics lien under Fla. Stat. § 713.05 and § 713.06. The specific filing requirements depend on your contract tier — whether you contracted directly with the owner or with a general contractor or another subcontractor.
Direct contracts with the owner (privity): If you have a written contract directly with the property owner, you are not required to serve a Notice to Owner. You can record a Claim of Lien directly within 90 days of last furnishing.
No direct contract with the owner (no privity): If you contracted with a GC, another sub, or a developer — this is the majority of subcontractors — you must serve a Notice to Owner within 45 days of first furnishing before your lien rights are valid. This includes electricians, plumbers, HVAC subs, roofers, drywall crews, painters, and material suppliers.
Laborers: Workers who supply only their own labor and are not in a supervisory role are exempt from the NTO requirement under Fla. Stat. § 713.06(2)(a).
What Is the Notice to Owner (NTO) Deadline in Florida?
The NTO must be served no later than 45 days after the date you first furnished labor, materials, or services on the project, per Fla. Stat. § 713.06(2)(c). That clock starts the day you show up on the job — not the day you sign a contract, not the day you invoice.
A few practical points on this deadline:
- "First furnishing" means the first day you delivered materials or performed work, even if it was a small mobilization day or a partial delivery.
- If you serve the NTO after the 45-day window, you do not lose all lien rights — but your lien is only valid for labor and materials furnished in the 45 days before the date you served the notice, per Fla. Stat. § 713.06(2)(c).
- If you never serve the NTO at all, you cannot file an enforceable lien. The lien will be dismissed.

Who Must Receive the Florida Notice to Owner?
Under Fla. Stat. § 713.06(2)(c), the NTO must be served on the following parties:
- The property owner — or the owner's agent or designee listed on the building permit
- The general contractor — the party at the top of the contract chain who holds the prime contract with the owner
- The construction lender, if any — the lender financing the construction must also receive the NTO
To identify the owner and lender, check the Notice of Commencement (NOC). Florida law requires the GC or owner to record a Notice of Commencement in the county land records before construction begins, under Fla. Stat. § 713.13. The NOC contains the owner's name and address, the lender's information, and the property description. If no NOC was recorded, serve the property owner at the address listed on the county property appraiser's records.
How Must the Notice to Owner Be Served in Florida?
Florida law specifies the valid delivery methods for the NTO under Fla. Stat. § 713.18:
- Certified mail, return receipt requested — the most common and most defensible method
- Personal delivery — delivering directly to the party or their registered agent
- Overnight courier with delivery confirmation
Certified mail is the standard. Keep your Certificate of Mailing and the green card (or electronic return receipt). If you ever need to enforce your lien in court, you will need proof that the NTO was properly served and when. USPS Certified Mail costs $4.85 as the base fee in 2026, per USPS Notice 123, plus First-Class postage and the return receipt fee.
What Must the Florida Notice to Owner Include?
A valid NTO under Fla. Stat. § 713.06(2)(c) must contain the following information:
- The name and address of the party giving the notice (you)
- The name and address of the party who hired you (your direct customer — the GC or sub above you)
- A description of the labor, services, or materials you are providing
- A description of the real property sufficient to identify it (address and legal description)
- The name and address of the property owner as shown in the Notice of Commencement
Florida provides a statutory form for the NTO in Fla. Stat. § 713.06(2)(c). Using this form verbatim — or an attorney-reviewed equivalent that includes all required elements — satisfies the requirement. Missing a required element can invalidate the notice.
How Do You Record a Mechanics Lien Claim in Florida?
Once you have served the NTO and you still haven't been paid, the next step is recording a Claim of Lien. Here is the process:
Step 1 — Confirm your deadline. You have 90 days from the last date you furnished labor or materials to record your Claim of Lien, per Fla. Stat. § 713.08(5). This is a hard deadline. Courts have no discretion to extend it.
Step 2 — Prepare the Claim of Lien document. Under Fla. Stat. § 713.08, the Claim of Lien must include:
- A description of the real property
- The name of the property owner
- The name and address of the lienor (you)
- The name of the person who hired you
- The labor, services, or materials furnished
- The contract amount, and the unpaid amount claimed
- The first and last dates you furnished labor or materials
- The date the NTO was served (for those required to serve one)
Step 3 — Have it signed and notarized. The Claim of Lien must be signed under oath — meaning it must be notarized, per Fla. Stat. § 713.08(3).
Step 4 — Record it with the Clerk of Court. File the notarized Claim of Lien with the Clerk of the Circuit Court in the county where the property is located. Recording fees vary by county but are typically $10–$15 for the first page plus a small fee per additional page.
Step 5 — Serve a copy on the property owner. Within 15 days of recording, you must serve a copy of the Claim of Lien on the property owner, per Fla. Stat. § 713.08(4)(c). Use certified mail or another method approved under Fla. Stat. § 713.18.
What Happens After You File the Mechanics Lien in Florida?
Recording the lien is not the end — it is the beginning of a formal payment dispute process. Here is what happens next and what deadlines apply:
The owner has options. After your lien is recorded, the property owner can:
- Pay you and demand a lien release
- Transfer the lien to a bond (which releases the property but preserves your claim against the bond)
- File an action to show cause why the lien should not be enforced (a "lien contest")
You must file suit to enforce the lien. Under Fla. Stat. § 713.22, you have 1 year from the date of recording the Claim of Lien to file a lawsuit to enforce it. If the owner records and serves a Notice of Contest of Lien, that 1-year period is shortened to 60 days from the date of service of the Notice of Contest, per Fla. Stat. § 713.22(2).
Lien releases. Once paid, you are required to provide a Satisfaction of Lien and record it in the same county within a reasonable time. Florida also uses conditional and unconditional lien waivers (Fla. Stat. § 713.20) at various payment milestones — read every waiver you sign carefully before signing.
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. A properly recorded mechanics lien is one of the few tools that actually moves slow payers.

What Are the Most Common Mistakes Florida Subs Make With Mechanics Liens?
Florida lien law is strict. These are the mistakes that kill valid claims:
1. Missing the 45-day NTO window. This is the most common error. Subs assume they have more time because the job is still going. The clock starts on day one of furnishing — not when you invoice, not when you submit for payment.
2. Serving the NTO on the wrong parties. Forgetting to serve the construction lender when one exists can be fatal to your claim against the lender's interest.
3. Using an incomplete or non-compliant form. A notice that omits a required element under Fla. Stat. § 713.06(2)(c) can be challenged and dismissed.
4. Missing the 90-day Claim of Lien deadline. There are no extensions, no excusable delays, no exceptions. Miss it and your lien rights are gone.
5. Not following up after recording. Failing to serve the owner within 15 days of recording, or failing to file suit within 1 year (or 60 days after a Notice of Contest), extinguishes the lien.
The math on compliance is simple. A single LienFlash notice is $24.99. If it preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, that is a 60,000% return on the cost of filing — and on a $75,000 contract, the return exceeds 300,000%.
Frequently Asked Questions
Does a Florida subcontractor always need to file a Notice to Owner?
No. Only subcontractors and suppliers who do not have a direct contract with the property owner are required to serve a Notice to Owner under Fla. Stat. § 713.06(2)(c). If you contracted directly with the owner, you can record a Claim of Lien without serving an NTO. If you contracted with a GC or another sub, the NTO is mandatory.
What happens if I serve the Florida Notice to Owner late?
If you serve the NTO after the 45-day deadline, you do not lose all lien rights. Under Fla. Stat. § 713.06(2)(c), your lien will be valid only for labor and materials furnished in the 45 days before the date you actually served the notice. Work performed before that window is unprotected. Serve it as soon as you realize you missed the deadline — protecting partial rights is better than nothing.
Can I file a mechanics lien in Florida without an attorney?
Yes. Florida law does not require an attorney to prepare or record a Claim of Lien. However, the form must be legally compliant and notarized. If you use a defective form, the lien can be challenged. If you need to file suit to enforce the lien, you will need an attorney for that step. Using an attorney-reviewed template from the start reduces the risk of a technical defect.
How long does a Florida mechanics lien last?
A recorded Claim of Lien is effective for 1 year from the date of recording, per Fla. Stat. § 713.22. You must file a lawsuit to enforce it within that 1-year period. If the owner serves a Notice of Contest of Lien, the enforcement window shortens to 60 days from service of that notice.
Can a property owner make a Florida mechanics lien go away?
Yes. The owner can transfer the lien to a bond under Fla. Stat. § 713.24. This releases the property from the lien but substitutes a surety bond as security for your claim. Your rights are preserved — the lien claim is now against the bond rather than the real property. The owner can also contest the lien in court, or simply pay the debt and demand a Satisfaction of Lien from you.
What is a Notice of Commencement and why does it matter for my NTO?
The Notice of Commencement (NOC) is a document recorded by the property owner or GC before construction begins, under Fla. Stat. § 713.13. It identifies the owner, the lender, the GC, and the property. You use the NOC to find the correct names and addresses for your NTO. If you cannot locate the NOC at the county recorder's office, serve the NTO on the owner at the address listed with the county property appraiser. Do not skip this step — sending the NTO to the wrong address defeats the notice.
Do mechanics lien rights apply to both residential and commercial projects in Florida?
Yes. Florida's Construction Lien Law under Chapter 713 applies to both residential and commercial real property. However, on a homestead property, additional protections for homeowners under Fla. Stat. § 713.10 can limit lien rights to the amount unpaid by the owner to the GC at the time the NTO is served. This is why serving your NTO early — before the owner has made large progress payments to the GC — directly affects how much of your claim is protected.
What is the recording fee to file a mechanics lien in Florida?
Recording fees are set by the county Clerk of Circuit Court and vary slightly, but are typically $10 for the first page and $8.50 for each additional page. A standard Claim of Lien is usually 1–2 pages, putting the typical recording cost in the $10–$20 range. This fee is separate from the cost of preparing and serving the NTO.
Protect Your Lien Rights Before the Deadline Passes
The 45-day NTO deadline runs from the day you first show up on a job — not when you invoice, not when you realize the GC is slow-paying. By the time a payment dispute starts, many subs have already missed the window.
LienFlash generates attorney-reviewed, Florida-compliant Notice to Owner forms and sends them via USPS Certified Mail in under 2 minutes. You get a Certificate of Mailing PDF the same day — the proof you need if you ever have to enforce.
