Stat. § 713.06. LienFlash files your NTO in 2 minutes for $24.99. published: 2026-06-25T10:28:40.693Z updated: 2026-06-25T10:28:40.693Z canonical: https://lienflash.app/blog/notice-to-owner-florida author: Grant Larsen publisher: LienFlash --- # Florida Notice to Owner: Filing Requirements and Service Rules 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) within 45 days of first furnishing labor, materials, or services to the project, under [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(a). The notice must be served on the property owner, general contractor, and any construction lender of record. Failure to serve the NTO on time does not eliminate lien rights entirely — but service after the 45-day window limits protection to work performed after the date notice was actually served. Failing to serve an NTO at all is a complete bar to mechanics lien rights for parties without a direct contract with the owner on private works projects in Florida. ## Who Is Required to Serve a Florida Notice to Owner? Any party in the construction chain who lacks a direct contract with the property owner must serve an NTO to preserve lien rights. That includes first-tier subcontractors, second-tier subcontractors (sub-subcontractors), material suppliers, equipment lessors, and laborers who are not on the general contractor's direct payroll. General contractors and specialty contractors who contract directly with the owner are exempt from the NTO requirement — their lien rights attach automatically through their direct contract. However, if you are a subcontractor hired by the GC, or a supplier providing materials to a sub, you have no automatic lien rights. The NTO is the mechanism that puts the owner on notice that you are on the project and that their property could be subject to a lien if you go unpaid. Architects, engineers, and licensed surveyors who are not in direct privity with the owner must also serve an NTO under [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(a) if they want to preserve lien rights for professional services. ## What Is the Florida Notice to Owner Deadline? The NTO must be served no later than 45 days after the lienor first furnishes labor, materials, or services to the project. The clock starts on the actual first day you set foot on the job or deliver the first load of materials — not the date your contract is signed, and not the date work was scheduled to begin. This is one of the most common mistakes Florida subs make: they count the 45 days from when they signed the contract or from the project's scheduled start date. Under [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(a), the trigger is first furnishing. If you mobilized on April 1 and served the NTO on May 17, you are one day late. Work performed before the late service date is unprotected. If you miss the deadline, your lien rights are not wiped out entirely. Under the statute, a late NTO still protects labor and materials furnished after the date of service — but everything before that date falls outside your lien protection. On a $50,000 subcontract where $35,000 worth of work was completed before you served late, that $35,000 is gone from any lien claim. [Florida lien deadline reference](/deadlines/florida) ## Who Must Be Served With the Florida NTO? Under [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(c), the NTO must be served on each of the following parties: **Property Owner:** The owner listed in the building permit or Notice of Commencement (NOC) recorded in the county official records. If the property is owned by an LLC or trust, serve the registered agent or the entity itself — not just an individual's name unless that individual is the titled owner. **General Contractor:** The GC named in the Notice of Commencement. If there is no GC (owner-builder projects), serve the owner in their capacity as the GC. **Construction Lender:** If a construction loan is in place and identified in the recorded Notice of Commencement, the lender must also receive a copy of the NTO. Skipping the lender when one exists is a defect that can weaken your lien position. The Notice of Commencement is your roadmap. Under [Fla. Stat. § 713.13](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.13.html), owners are required to record an NOC before construction begins, and it must contain the name and address of the owner, GC, and lender. Pull the recorded NOC from the county clerk's website before you prepare the NTO — using the correct legal names and addresses is not optional. ## How Must the Florida NTO Be Served? Florida law under [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(c) requires that the NTO be served by one of these three methods: 1. **Certified mail, return receipt requested** — the most common method and the easiest to prove in a dispute 2. **Personal delivery** with a written acknowledgment of receipt 3. **By any other means permitted by Chapter 48** of the Florida Statutes (the general service of process rules) In practice, certified mail is the standard. It creates a paper trail — the tracking number, the USPS delivery scan, and the green card (or electronic return receipt) establish exactly when service occurred. USPS Certified Mail currently costs $4.85 as the base fee, per the USPS Notice 123 Price List effective 2026, with electronic return receipt adding another $2.46. Keep your Certificate of Mailing and all delivery confirmations. If a payment dispute ends up in litigation or at a lien dispute hearing, you will need to prove service — both that the notice was sent and when it was sent. A Certificate of Mailing from the post office is strong evidence; a claim that "we mailed it" without documentation is not. ## What Information Must Be Included in the Florida NTO? Under [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(a), a valid Florida Notice to Owner must contain the following information: - The name and address of the lienor (the party serving the notice) - The name and address of the person who hired the lienor (e.g., the GC who subcontracted the work) - A description of the real property being improved, sufficient to identify it - A general description of the services or materials being provided - The name of the property owner as identified in the Notice of Commencement The statute also requires that the notice include specific language warning the owner that they may be personally liable and that their property may be subject to a lien unless they ensure payment is made. Florida provides a statutory form for this language in [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html)(2)(b). Using the verbatim statutory language is the safest approach — deviation from the required warning text can render the notice defective. Do not confuse a Florida NTO with a simple letter introducing yourself to the owner. The NTO is a legal document with statutory content requirements. A generic email or informal letter does not satisfy the requirement. ## Does the Florida NTO Apply to Public Projects? No. The Florida Notice to Owner requirement under [Fla. Stat. § 713.06](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.06.html) applies only to private construction projects. Public projects — work performed for state, county, municipal, or federal agencies — are governed by separate laws, primarily the Florida Public Construction Bond Statute under Fla. Stat. § 255.05. On public projects, the payment protection mechanism is a payment bond claim, not a mechanics lien. To preserve your right to make a claim against a public payment bond, you must serve a notice on the contractor and the bonding company within 90 days of your last furnishing. The rules differ substantially, so confirm the project ownership before assuming either set of rules applies. [Florida Mechanics Lien Guide](/learn/florida-mechanics-lien) ## What Happens After You Serve the NTO? Serving the NTO preserves your right to record a mechanics lien if you go unpaid — it does not by itself create a lien on the property. The NTO is the prerequisite. After serving it, you still need to do the following if payment does not come: **Record a Claim of Lien:** Under [Fla. Stat. § 713.08](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.08.html), a Claim of Lien must be recorded in the county official records within 90 days of the lienor's last furnishing of labor or materials. Missing this window eliminates lien rights regardless of whether a valid NTO was served. **Serve a Copy of the Claim of Lien:** Within 15 days of recording the Claim of Lien, you must serve a copy on the owner. **File a Lawsuit to Enforce the Lien:** Under [Fla. Stat. § 713.22](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.22.html), a mechanics lien must be enforced by filing a lawsuit within one year of recording the Claim of Lien, or within 60 days of the owner recording a Notice of Contest of Lien — whichever comes first. The NTO is step one in a sequence. Serve it correctly and on time, and you preserve your options. Skip it, and no amount of diligent lien recording downstream will save your claim. 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. In that environment, your lien rights are a critical financial tool — not a last resort. ## How Much Does It Cost to File a Florida NTO, and Is It Worth It? The cost of filing a Florida NTO is minimal compared to the protection it provides. A single NTO through LienFlash costs $24.99, which includes an attorney-reviewed, state-compliant form and USPS Certified Mail with Certificate of Mailing. If that notice preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, the return on that $24.99 exceeds 60,000%, based on LienFlash's own pricing applied to typical subcontract values. In 2024, preliminary notices were filed on construction projects valued at over $22.7 billion in the United States, according to Lienser via DocJoist's 2026 Construction Payment Statistics report. Florida subcontractors who skip the NTO are handing away legal protection that their competitors are actively using. The math is straightforward: $24.99 to protect thousands of dollars in receivables. The only scenario where the NTO is not worth filing is a project where you have already been paid in full before the 45-day window closes. [Florida lien resources](/resources/florida-notice-to-owner) ## Frequently Asked Questions ### Does a first-tier subcontractor in Florida need to serve an NTO? Yes. A first-tier subcontractor — meaning one hired directly by the GC, not by the property owner — must serve a Florida Notice to Owner within 45 days of first furnishing. The NTO exemption applies only to parties with a direct contract with the property owner. If your contract is with the GC, you must serve the notice. ### Can I serve the Florida NTO after the 45-day deadline? You can serve the NTO after the deadline, but it will only protect labor and materials furnished after the date of service. Any work completed before your late service date is not protected by the lien. Serving late is better than not serving at all, but the protection is reduced and the unprotected amount may be significant depending on project timing. ### Where do I find the property owner's name and address for the NTO? Pull the recorded Notice of Commencement from the county clerk of courts website for the county where the project is located. The NOC is required to list the owner's legal name and address, the GC's information, and any construction lender. Using the names and addresses exactly as they appear in the NOC is the safest approach. ### Does the Florida NTO protect me on change orders and extra work? Generally, yes — as long as the extra work is performed on the same project and you have already served a valid NTO. However, if extra work significantly expands the scope and the original NTO did not describe that scope, serving an amended or supplemental NTO is a prudent step. When in doubt, serve a new notice for the expanded scope. ### What if the property owner is a trust or LLC? Serve the NTO on the entity (trust or LLC) at the address listed in the Notice of Commencement. For LLCs, you may also serve the registered agent on file with the Florida Division of Corporations. Using only an individual's name when the titled owner is a legal entity is a defect that could be challenged in a lien dispute. ### Is a Florida NTO the same as a mechanics lien? No. The Notice to Owner is a preliminary notice that preserves your right to record a mechanics lien later if payment is not made. The NTO itself does not create a lien on the property. If you go unpaid after serving the NTO, you must separately record a Claim of Lien within 90 days of your last furnishing under [Fla. Stat. § 713.08](https://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0713/Sections/0713.08.html). ### Do material suppliers need to serve a Florida NTO? Yes. Material suppliers who furnish materials to a GC or subcontractor — without a direct contract with the property owner — must serve an NTO within 45 days of first delivery. This applies whether you supply lumber, electrical materials, plumbing fixtures, HVAC equipment, or any other construction materials incorporated into the project. ### What if there is no recorded Notice of Commencement on the project? If no NOC has been recorded, you are still required to serve the NTO on the owner and GC. Conduct a public records search at the county clerk's office to find the owner's information from the building permit or property records. The absence of an NOC does not excuse the NTO requirement — it just means you need to find the serving addresses through alternative public records. ## Protect Your Lien Rights Today The 45-day clock on your Florida Notice to Owner starts the day you first set foot on the job or make the first delivery — not when you sign the contract, not when you get around to it.
