If you're a subcontractor or supplier working on a Florida construction project, filing a Notice to Owner (NTO) is the single most important step you can take to protect your right to get paid. Miss this deadline and you permanently lose your ability to file a mechanics lien — no exceptions, no extensions.

What Is a Notice to Owner in Florida?
A Notice to Owner is a written document that notifies the property owner and general contractor that you are providing labor, materials, or services on their project. Under Fla. Stat. § 713.06(2)(a), any lienor who does not have a direct contract with the property owner must serve a Notice to Owner to preserve their lien rights. Without it, you cannot enforce a mechanics lien in Florida — period.
This requirement applies to subcontractors, sub-subcontractors, material suppliers, and equipment lessors. If you're a general contractor with a direct contract with the owner, you do not need to file an NTO. Everyone else does.
Who Is Required to File a Notice to Owner in Florida?
Any party without a direct contract with the property owner is required to file an NTO. That means:
- Subcontractors hired by the general contractor
- Sub-subcontractors hired by a subcontractor
- Material suppliers delivering to the job site
- Equipment lessors providing equipment to a contractor or subcontractor
- Laborers (in some circumstances)
If you fall into any of these categories and you are not paid, your only path to filing a lien runs directly through a timely Notice to Owner. Painters, electricians, plumbers, HVAC techs, roofers, drywall crews — this requirement hits every trade that works under a general contractor.
What Is the Deadline to File a Notice to Owner in Florida?
You must serve your Notice to Owner before the 45th day after you first furnish labor or materials to the project, according to Fla. Stat. § 713.06(2)(c). This is one of the strictest deadlines in the country — it's calendar days, not business days, and there is no grace period.
Here's how the math works: If you show up on a job site and start work on January 1st, your NTO must be served no later than February 14th. Miss that date by a single day and your lien rights for all work performed are gone.
One important nuance: Work performed more than 45 days before the NTO is served is excluded from your lien claim. So even if you file late, you may still protect future work — but you lose protection for everything already done. The smart move is always to file before you start work or on day one.

What Information Must Be Included in a Florida Notice to Owner?
Florida law under Fla. Stat. § 713.06(2)(c) specifies exactly what must appear in your NTO. A legally sufficient Notice to Owner must include:
- Your name and address (the lienor serving the notice)
- The name and address of the person who hired you (your direct contracting party)
- A description of the labor, services, or materials you are providing
- The legal description of the property or the street address sufficient to identify the property
- The name of the property owner as listed in the building permit or public records
Florida law also provides a statutory form for the Notice to Owner. While you are not required to use that exact form, your notice must contain all the required elements. Missing even one field can render your notice legally defective and void your lien rights.
The notice must also include a specific warning statement to the owner as prescribed by the statute. This warning notifies the owner that a lien may be filed on their property if payment is not made.
How Do You Properly Serve a Notice to Owner in Florida?
Serving a Notice to Owner in Florida requires using a legally recognized delivery method — this is where many contractors make expensive mistakes. Under Fla. Stat. § 713.18, service must be made by one of the following methods:
- Certified mail, return receipt requested — the most common and most defensible method
- Personal delivery to the person being served
- By leaving notice at the person's usual place of business
Certified mail is the industry standard because it creates a paper trail. You want a USPS tracking number, a Certificate of Mailing, and proof of delivery. If a dispute ever lands in court, that paper trail is what protects you.
You must serve the NTO on:
- The property owner (or the owner's agent)
- The general contractor on the project
If there is a construction lender involved, you must also serve the lender under Fla. Stat. § 713.06(2)(c).
One critical rule: proper service is complete when the notice is mailed, not when it is received. So if your deadline is February 14th, the notice must be postmarked by February 14th. Late delivery is not your problem — late mailing is.
Who Must Be Served With the Florida NTO?
Under Fla. Stat. § 713.06(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, 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 Do You Find the Property Owner's Name and Address?
You find the property owner's name and address through the county property appraiser's website or the county clerk's public records. Every Florida county maintains searchable online databases. Search by the property address, and you'll pull up the owner of record, the legal description, and often the mailing address.
For condos, commercial projects, or projects owned by an LLC or entity, dig deeper. The NTO must name the actual property owner as they appear in the public record. Serving a notice to the wrong party — even with the right address — can be challenged as improper service.
If a Notice of Commencement has been recorded (required for most permitted projects under Fla. Stat. § 713.13), that document lists the owner, contractor, and lender information. Pull it from the county clerk's records before you prepare your NTO — it gives you everything you need in one place.

How Much Does It Cost to File a Notice to Owner in Florida?
Filing a Notice to Owner in Florida is not a court filing — you do not pay a filing fee to a government office. Your costs are the preparation and delivery costs only.
Here's what it typically costs if you do it yourself:
- USPS Certified Mail with Return Receipt: approximately $8–$10 per mailing
- Your time to research owner info, draft the notice, and make the post office run
If you're sending to an owner and a general contractor, that's two separate certified mailings — around $16–$20 in postage.
With LienFlash, a single Notice to Owner costs $24.99, which covers the attorney-reviewed NTO template, USPS Certified Mail delivery, and a Certificate of Mailing PDF delivered to your inbox. Filing takes about 2 minutes. For contractors who file multiple notices per month, the Pro Plan at $49/month covers 3 notices per month, and the Pro Annual plan at $399/year brings the per-notice cost down significantly.
Does the Florida NTO Apply to Public Projects?
No. The Florida Notice to Owner requirement under Fla. Stat. § 713.06 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.
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, 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, 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.
What Happens If You Miss the Florida Notice to Owner Deadline?
If you miss the 45-day deadline under Fla. Stat. § 713.06(2)(c), you lose the ability to file a mechanics lien for the work performed outside the protected window. You cannot extend the deadline. You cannot file retroactively. The court will not give you a pass because you were busy or didn't know about the requirement.
What this means practically:
- If the GC or owner doesn't pay you, your only remaining option is a breach of contract lawsuit
- You lose your priority position over lenders and other creditors
- Collecting a judgment through a lawsuit costs more and takes longer than enforcing a lien
Florida courts have consistently upheld this strict deadline. In disputes where subcontractors filed even one day late, they were denied lien rights. The statute is not ambiguous, and judges don't treat it as a technicality.
The fix is simple: file your NTO before you start work on every project. Make it a non-negotiable part of your new-project checklist alongside your contract and insurance certificate.
Frequently Asked Questions
Does a Notice to Owner in Florida need to be notarized?
No. Florida law does not require a Notice to Owner to be notarized. It must be signed by the lienor or their authorized agent, but notarization is not a legal requirement under Fla. Stat. § 713.06. What matters is that the notice contains all required information and is served by a legally recognized method before the 45-day deadline.
Can I file a Florida Notice to Owner after work has already started?
Yes, but only future work is protected. Under Fla. Stat. § 713.06(2)(c), work performed more than 45 days before the notice is served is excluded from your lien claim. If you started work 30 days ago and haven't filed yet, file today — you'll protect everything from day 16 forward, but days 1–15 are unprotected if you're already past the 45-day window.
Who do I need to serve the Notice to Owner on in Florida?
You must serve the Notice to Owner on the property owner and the general contractor. If a construction lender is involved, you must also serve the lender. All parties must be served within the 45-day window under Fla. Stat. § 713.06(2)(c). Serving only the owner and missing the GC is a defective notice.
Is a Notice to Owner the same as a mechanics lien in Florida?
No. A Notice to Owner is a preliminary notice that preserves your right to file a mechanics lien later. It is served early in the project — within 45 days of first furnishing. A mechanics lien is filed much later, after non-payment, and must be filed within 90 days of the last day you furnished labor or materials under Fla. Stat. § 713.08(5). You cannot file a valid mechanics lien without first serving a timely NTO.
Does a Notice to Owner apply to residential projects in Florida?
Yes. Florida's NTO requirement applies to both residential and commercial projects. There is no exemption for single-family homes or residential remodels. If you are a subcontractor on any permitted residential construction project in Florida without a direct contract with the owner, you must file a Notice to Owner to protect your lien rights.
What if I'm a material supplier — do I need to file a Notice to Owner in Florida?
Yes. Material suppliers who supply materials to a contractor, subcontractor, or any party other than the property owner directly must serve a Notice to Owner under Fla. Stat. § 713.06(2)(a). The 45-day clock starts from the first delivery of materials to the project site, not the date of your invoice or purchase order.
Can a general contractor file a Notice to Owner in Florida?
A general contractor with a direct contract with the property owner does not need to and typically does not file a Notice to Owner. However, if a general contractor is hired by a developer or a lease-hold contractor without direct ownership, the requirement may apply. When in doubt, check whether the party paying you is the titled owner of the property. If they're not, file the NTO.
How long does it take for a Notice to Owner to be delivered?
USPS Certified Mail typically delivers in 2–5 business days. Remember: service is complete upon mailing, not delivery, under Fla. Stat. § 713.18. So the delivery timeline doesn't affect your deadline — your postmark date is what the court looks at. File early enough to have a clean paper trail, not just a postmark squeaking in on day 45.
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.
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.
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.
