On a Florida construction job, your best protection against nonpayment is a construction lien. But that protection starts with one document, served at the beginning of every job: the Notice to Owner.
If you have a direct contract with the property owner, you are already in privity, and the NTO requirement generally does not apply to you. But if you are a subcontractor, supplier, or any other party whose contract is with the GC or someone else down the chain, you are not in privity with the owner. That means you must serve a Notice to Owner before you can file a construction lien in Florida. No NTO, no lien. No lien, no leverage.
This guide covers the Florida Notice to Owner requirement under Florida Statute §713.06, who must serve it, who must receive it, and what you need to do to protect your lien rights from day one on every job. The statute was most recently amended in 2023, and this article reflects current Florida law.
What Is a Florida Notice to Owner?
A Notice to Owner is a written preliminary notice required by Florida Statute §713.06. It tells the property owner that you, a party without a direct contract with that owner, are contributing labor, materials, or services to their project. It puts the owner on notice that you exist on the job and that you have the right to file a construction lien if you are not paid.
In practical terms, the Notice to Owner (NTO) serves as both a courtesy and a legal safeguard. When you send an NTO, you are formally letting the property owner know who you are, what type of work you’re performing, what materials you’re supplying, and with whom you have a direct contract—whether that’s the general contractor or someone further down the chain. This notice is crucial because it preserves your right to payment if the contractor above you fails to pay you.
It’s important to remember: the NTO is not itself a lien. It does not cloud the property’s title or appear in the public record. However, it is the essential first step for most subcontractors and suppliers who want to protect their lien rights. Property owners should pay close attention to these notices; before making final payment to a contractor, the owner should verify that anyone who has sent a Notice to Owner has actually been paid. This is usually done by collecting a lien waiver from the party that sent the NTO.
“All lienors under this section, except laborers, as a prerequisite to perfecting a lien under this chapter and recording a claim of lien, must serve a notice on the owner…” — Florida Statute §713.06(2)(a)
Who Must Serve a Florida Notice to Owner?
The determining factor is privity, which simply means whether you have a direct contractual relationship with the property owner. If you do, you are generally exempt. If you do not, you almost certainly need to serve an NTO.
You Must Serve an NTO If You Are:
- A subcontractor whose contract is with the general contractor, not the owner
- A sub-subcontractor whose contract is with a subcontractor
- A material supplier not in direct contract with the property owner
- An equipment rental company supplying to a GC or subcontractor
- Any other party furnishing labor, services, or materials without a direct owner contract
You Are Exempt If You Are:
- A general contractor with a direct contract with the owner
- A laborer, meaning a W-2 employee paid wages, not an independent contractor
- A professional lienor such as an architect, engineer, or land surveyor with a direct owner contract under §713.03
When in doubt, serve it. Sending an NTO when you did not strictly need to causes no harm. Not sending one when you did need to permanently destroys your lien rights. There is no upside to skipping it.
The 45-Day Deadline and the Day 40 Rule
You must serve your NTO no later than 45 days after you first furnish labor, services, or materials to the project. First furnishing means the very first day you did anything on the job: dropped off materials, showed up to prep, made the first cut. It does not mean the first day of your main scope of work.
“The notice must be served before commencing, or not later than 45 days after commencing, to furnish his or her labor, services, or materials…” — Florida Statute §713.06(2)(a)
Florida courts have enforced this deadline without exception. Failure to serve the NTO on time is a complete defense to lien enforcement under §713.06(2)(a). That means the owner wins automatically. It does not matter that you did the work, that you were not paid, or that the GC was dishonest. Late service is no service.
Why You Should Mail by Day 40, Not Day 45
Certified mail typically takes two to five days to deliver. Mail on day 44 and it may arrive on day 48. You are late, and your lien rights are gone.
Florida Statute §713.18(2) provides a mailing presumption: if you mail your NTO by certified or registered mail within 40 days of first furnishing, service is considered effective on the date of mailing, not the date of receipt. That presumption protects you from postal delays and gives you a meaningful buffer.
To use the presumption, you need to keep either a mail log showing the certified mail number, the recipient’s name and address, and the USPS date stamp, or your USPS electronic tracking records. Save them on every job.
Mail by day 40 on every job. No exceptions.

Who Must Receive the Notice to Owner?
Serving the right parties is just as important as serving on time. A properly worded NTO mailed to the wrong people does not protect your lien rights.
The Property Owner
Always required. Serve every person identified as an owner in the recorded Florida Notice of Commencement. On commercial projects there may be multiple owners. Serve them all. The address to use is the one listed in the Notice of Commencement filed with the county clerk. That is the legally controlling address under Chapter 713.
The General Contractor
Florida Statute §713.06(2)(a) requires that a copy of the NTO be served on the contractor. This is not optional. Skipping the GC is one of the most common and costly mistakes subcontractors and suppliers make.
Materialmen to Sub-Subcontractors
Sub-subcontractors and materialmen to subcontractors must serve a copy of the NTO on the contractor, in addition to the owner. If you are a material supplier and your contract is with a sub-subcontractor, you must also serve the contractor, and you must serve the subcontractor if you know their name and address. Florida Statute §713.06(2)(a) is explicit: failure to serve all required parties is a complete defense to lien enforcement.
The Construction Lender
If the recorded Notice of Commencement identifies a construction lender, that lender must also receive a copy of your NTO, addressed to the person and address designated in the NOC. Check the NOC carefully on every job.
How to Serve the Notice to Owner
Florida Statute §713.18 sets out your options. Any of these methods works:
- Certified mail with return receipt requested
- Hand delivery with a signed receipt
- A courier service such as FedEx or UPS with proof of delivery
- Service by a licensed process server
Certified mail is the most common and the most defensible. Mail your NTO by day 40, keep the receipt, and save your tracking number. Mailing by day 40 locks in the date of mailing as the date of service under §713.18(2), protecting you from postal delays. If the notice comes back undelivered or is refused, Florida law still considers it served, as long as it was sent to the correct address and the non-delivery was through no fault of yours.
On jobs where you have reason to believe the owner or GC may refuse delivery, send it by certified mail and a courier simultaneously. The more documentation you have, the stronger your position.
Does the NTO Appear in the Public Record?
No. The Notice to Owner does not appear in the public record, does not show up in a title search, and creates no encumbrance on the property. It is a private notice between you and the required recipients.
Only a recorded Claim of Lien affects the property’s title. The NTO simply preserves your right to file that lien if you are not paid. When that day comes, our step-by-step guide to filing a construction lien in Florida.
Common Mistakes That Cost Contractors Their Lien Rights
These are the errors Florida courts see most often. Avoid all of them.
- Missing the 45-day deadline. There is no grace period and no exception. Late service is a complete defense for the owner.
- Using the wrong address. The address must come from the recorded Notice of Commencement. An NTO sent to an incorrect address may not be valid service.
- Failing to serve the general contractor. §713.06(2)(a) requires it. Serving the owner alone is not enough.
- Waiting until there is a payment problem. The NTO must go out at the start of every job, not when things go sideways.
- Not keeping documentation. If you cannot prove you served the NTO correctly, you cannot enforce your lien.
Frequently Asked Questions
Q: What happens if I miss the 45-day NTO deadline?
You lose your lien rights entirely. Under Florida Statute §713.06(2)(a), failure to timely serve the NTO is a complete defense to enforcement of a lien. It does not matter that you did the work and were not paid. The deadline is absolute.
Q: Do I need to serve an NTO if I have a contract with the general contractor?
Yes. A contract with the GC is not a contract with the owner. Any party without a direct contract with the property owner is required to serve an NTO as a prerequisite to filing a construction lien in Florida.
Q: Can I send the NTO by email?
No. Florida law does not recognize email as a valid primary method of service for an NTO. Use certified mail, a courier with proof of delivery, hand delivery with a signed receipt, or a licensed process server.
Q: What address do I use when serving the NTO?
Use the address listed in the recorded Notice of Commencement for the owner and contractor. That is the legally controlling address under Chapter 713. If the NOC address appears incomplete, you are permitted to complete it using the county property appraiser’s records under §713.18(3)(b). Cross-reference both sources on every job.
Q: What if the owner refuses to accept the NTO?
Refusal does not defeat service, but only if you mailed by day 40. Under Florida Statute §713.18(2), mailing by day 40 makes service effective on the date of mailing regardless of what happens after. If you mailed after day 40 and the owner refuses, service is only effective when actually received, and a refusal means it never was. Mail by day 40, and a refused NTO cannot hurt you. Mail late, and a refusal can cost you everything. Document the refusal either way and send by an alternate method as a backup. Here’s exactly what to do when an NTO is returned or refused.
Q: Do I need to serve an NTO on a residential project?
Yes, if you do not have a direct contract with the homeowner. The NTO requirement under §713.06 applies to both residential and commercial projects. Subcontractors and suppliers on residential jobs are just as exposed without a timely NTO.
Q: Is there a standard form for the Florida NTO?
Yes. Florida Statute §713.06(2)(c) provides a statutory form for the Notice to Owner. The form must include specific warning language required by the statute. Using the statutory form or one that substantially complies with it is the safest approach.
Key Takeaways
| Key Takeaways The Florida Notice to Owner is a legal prerequisite to filing a construction lien. Without it, you have no lien rights, regardless of how much you are owed. If you do not have a direct contract with the property owner, you almost certainly need to serve an NTO. When in doubt, serve it. The deadline is 45 days from first furnishing. Mail by day 40 to lock in the mailing-date presumption under §713.18(2). Serve the owner, the general contractor, and the construction lender if one is identified in the Notice of Commencement. Missing any required recipient can defeat your lien. Use the address listed in the Notice of Commencement. An NTO sent to the wrong address may not constitute valid service. Keep your certified mail receipts and USPS tracking records on every job. You may need them to prove service. A refusal or returned NTO does not kill your lien rights, as long as you used the correct address and an approved delivery method. The NTO does not appear in the public record. It does not encumber the property. It only preserves your right to file a lien. |
