Florida Lien Law: A Subcontractor's Complete Guide
Last updated: July 2025
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) before the earlier of: (1) 45 days after first furnishing labor or materials, or (2) before the owner records a Notice of Commencement — with the deadline governed by Fla. Stat. § 713.06(2)(c). The NTO must be served on the property owner, general contractor, and construction lender (if any) via certified mail, registered mail, or personal delivery. Missing the 45-day deadline does not partially limit your rights — it eliminates your mechanics lien rights entirely on that project. No NTO means no lien, and no lien means you are an unsecured creditor if the owner or GC stops paying.
Who Must Serve a Notice to Owner in Florida?
Any party who does not have a direct contract with the property owner must serve a Notice to Owner to preserve lien rights. That means subcontractors, sub-subcontractors, material suppliers, and equipment lessors all fall under this requirement under Fla. Stat. § 713.06. If you were hired by the general contractor — not the owner — you are in this group. General contractors who have a direct contract with the owner are exempt from the NTO requirement, but they must record a Notice of Commencement before work begins.
Sub-subcontractors (companies hired by a sub, not the GC) face the same rule and the same 45-day deadline. The further down the payment chain you are, the more critical the NTO becomes, because you have zero direct relationship with the owner and zero leverage without it.
What Is the Exact Deadline for Florida's Notice to Owner?
The deadline is 45 days from the date you first furnish labor or materials to the project. Under Fla. Stat. § 713.06(2)(c), the NTO must be served no later than 45 days after the lienor's first furnishing. If you miss that window, your lien rights are gone — there is no cure, no extension, and no exception for good-faith mistakes.
A few practical points on timing:
- Day 1 is the first day you deliver materials or perform any labor on the job site, not the contract signing date.
- If you are unsure of the exact first-furnishing date, use the earliest possible date. Being early does not hurt you; being late kills your claim.
- Weekends and holidays do count toward the 45-day calendar count — this is not a "business days" deadline.

How Do You Properly Serve a Florida Notice to Owner?
A Florida NTO must be served by certified mail, registered mail, or personal delivery under Fla. Stat. § 713.18. Faxing or emailing the notice is not sufficient and does not satisfy the statute — even if the recipient acknowledges it. Serving by certified mail creates a paper trail with USPS tracking, which is critical if a payment dispute ends up in court or arbitration.
The NTO must be served on:
- The property owner (name and address from the Notice of Commencement)
- The general contractor
- The construction lender, if one is identified in the Notice of Commencement
You find this information on the Notice of Commencement, which the owner or GC is required to record in the county public records before work begins under Fla. Stat. § 713.13. Always pull the recorded Notice of Commencement before sending your NTO — it contains the exact legal names and addresses required for valid service.
USPS Certified Mail currently costs $4.85 as the base service fee (plus standard First-Class postage), according to the USPS Notice 123 Price List effective 2026. Adding electronic Return Receipt adds $2.46. That is a small price compared to losing a five- or six-figure receivable.
What Must the Florida Notice to Owner Contain?
Florida law specifies the required contents of a valid NTO under Fla. Stat. § 713.06(2)(c). The notice must include:
- The lienor's name and address
- A description of the services or materials being provided
- The name of the person who hired you (your direct customer)
- The property description (legal description or address sufficient to identify the property)
- A warning statement to the owner in the specific statutory language required by Fla. Stat. § 713.06(2)(c)
The statutory warning language is not optional boilerplate — it is a required element. A notice that omits it or uses substantially different language can be challenged as defective. This is why using an attorney-reviewed, state-compliant form matters. A generic template you found online may not include the exact wording Florida requires.
What Happens If You Skip the Notice to Owner?
If you fail to serve the NTO within 45 days of first furnishing, you lose your right to record a mechanics lien against the property. Full stop. You can still sue the GC or the party who hired you for breach of contract, but you cannot encumber the property — which means the property owner can pay off the GC and sell or refinance the property with no obligation to you.
This matters because payment problems in construction are not rare. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years prior. When a GC runs out of money or goes under, the mechanics lien is often the only tool a subcontractor has to recover what they are owed. Without it, you are standing in line with every other unsecured creditor.
The same report estimates slow payments cost the U.S. construction industry $280 billion in 2024 — roughly 14% added to total construction spending. Florida's construction market is large enough that subcontractors in this state absorb a meaningful share of that burden.
What Are the Florida Mechanics Lien Deadlines After the NTO?
Serving the NTO is step one. If you complete work and do not get paid, here is what follows under Florida lien law:
Record the Claim of Lien — You must record your mechanics lien in the county where the property is located no later than 90 days after your last furnishing of labor or materials, under Fla. Stat. § 713.08(5). "Last furnishing" means the last date you actually provided labor or materials — not the contract completion date, not the punch-list date, and not the date you invoiced.
Serve a copy of the Claim of Lien — Within 15 days of recording, you must serve a copy of the recorded lien on the owner under Fla. Stat. § 713.08(4)(a).
File a lawsuit to enforce the lien — A Florida mechanics lien is only valid for 1 year from the date of recording. If you do not file a lawsuit to enforce it within that window, the lien expires and is unenforceable under Fla. Stat. § 713.22.
Summary of key deadlines:
| Action | Deadline |
|---|---|
| Notice to Owner | 45 days from first furnishing |
| Claim of Lien (record) | 90 days from last furnishing |
| Serve copy of Claim of Lien | 15 days after recording |
| Lawsuit to enforce lien | 1 year from lien recording |
Does Florida Lien Law Apply to Public Projects?
No — Florida's mechanics lien statute under Chapter 713 applies to private construction projects only. Public property cannot be liened. For public projects (city, county, state, federal work), subcontractors and suppliers are protected through a different mechanism: the Payment Bond requirement under Fla. Stat. § 255.05.
On public projects over $200,000, the GC is required to post a payment bond. To make a claim against that bond, you must serve a Notice to Contractor within 45 days of first furnishing and file a formal bond claim within 90 days of last furnishing. The deadlines mirror the private lien process, but the legal mechanism — and the target of your claim — is entirely different.
Can an Owner Shorten or Waive Your Lien Rights by Contract?
Florida law prohibits contract provisions that purport to waive or limit lien rights before the lienor has been paid. Under Fla. Stat. § 713.20(2), any contractual provision that waives, releases, or impairs lien rights before payment is received is void and unenforceable. So if a GC or owner slips language into a subcontract trying to get you to sign away your lien rights upfront, that clause has no legal effect in Florida.
Lien waivers signed after payment is received are valid and enforceable. Florida uses four standardized lien waiver forms under Fla. Stat. § 713.20(4): conditional and unconditional waivers for both partial payments and final payment. Using any form other than the statutory forms is not recommended — courts have upheld the statutory forms, and deviation creates ambiguity.
Frequently Asked Questions
Does a Florida subcontractor need to serve a Notice to Owner on every project?
Yes, if you do not have a direct contract with the property owner. On every private project where you are hired by a GC or another sub, you need to serve a Notice to Owner within 45 days of first furnishing to preserve your mechanics lien rights. There are no exceptions based on project size, contract value, or your prior relationship with the GC.
What if I miss the 45-day Florida NTO deadline?
Missing the 45-day deadline means you lose your mechanics lien rights on that project entirely. You retain the right to sue the party who hired you for breach of contract, but you cannot file a mechanics lien against the property. There is no late-filing option or grace period under Fla. Stat. § 713.06.
Where do I find the property owner's name and address for the NTO?
Pull the Notice of Commencement recorded in the county public records where the project is located. It contains the owner's legal name and address, the GC's information, and the construction lender if applicable. Most Florida county property appraiser websites allow you to search by address. Never guess — an NTO served to the wrong party is the same as no NTO.
Do I need to send a Notice to Owner on residential projects?
Yes. Florida's NTO requirement applies to both commercial and residential private construction. There is no residential exemption for subcontractors. In fact, residential projects are where the NTO is often skipped — and where subcontractors most frequently lose payment disputes as a result.
Can I serve the Notice to Owner by email or fax?
No. Florida Stat. § 713.18 requires service by certified mail, registered mail, or personal delivery. Email and fax do not satisfy the statute. Even if the recipient confirms receipt electronically, an emailed NTO will not hold up as valid service if the lien is challenged in court.
How long does a Florida mechanics lien last?
A recorded Florida mechanics lien is enforceable for 1 year from the date it is recorded, under Fla. Stat. § 713.22. If you do not file a lawsuit to enforce the lien within that period, it expires automatically and can be officially discharged from the public record.
Is there a minimum dollar amount to file a Florida mechanics lien?
No. Florida law does not set a minimum contract or claim value for mechanics lien rights. A subcontractor owed $500 has the same statutory right to record a lien as one owed $500,000. Whether it makes economic sense to pursue the lien at very small amounts is a business decision, but the legal right exists regardless.
What is the difference between a Notice to Owner and a Notice of Commencement in Florida?
A Notice of Commencement is recorded by the property owner or GC before work begins — it establishes the project in the public record and triggers the lien law timeline under Fla. Stat. § 713.13. A Notice to Owner is served by subcontractors and suppliers to notify the owner that they are on the job and preserving lien rights under Fla. Stat. § 713.06. They are separate documents with separate requirements.
Protect Your Lien Rights Before the 45-Day Clock Runs Out
The 45-day deadline starts the moment you deliver your first load of materials or put the first crew on site. There is no reminder system built into Florida law — that responsibility falls entirely on you. LienFlash generates attorney-reviewed, Florida-compliant Notice to Owner forms and sends them via USPS Certified Mail in about two minutes. A single notice is $24.99. If it protects a $30,000 receivable that would otherwise go unpaid, that math is straightforward.
