Florida NOC vs. Notice to Owner: Key Differences Explained
Two critical documents. Two very different purposes. Here's exactly what each one does, who files it, and when.
Key Takeaways
- The NOC is filed by the property owner before work starts — it announces the project publicly.
- The NTO (Notice to Owner) is filed by subcontractors and suppliers — it preserves their right to file a mechanics' lien.
- Both documents serve completely different parties in completely different directions.
- Neither replaces the other — many projects require both.
Side-by-Side Comparison
| Factor | Notice of Commencement (NOC) | Notice to Owner (NTO) |
|---|---|---|
| Who files it? | Property owner (or authorized agent) | Subcontractors, suppliers, laborers |
| When? | Before work starts | Within 45 days of first furnishing |
| Where? | Recorded in county public records | Served on owner, GC, and lender (not recorded) |
| Statute | § 713.13, F.S. | § 713.06, F.S. |
| Purpose | Announces project; provides contact info for lien notices | Preserves lien rights of sub-tier parties |
| Required for GC? | N/A — owner files NOC | No — GC has direct contract with owner |
| If not filed? | Owner loses protections; lien complications | Subcontractor/supplier loses lien rights |
The NOC — The Owner's Document
The NOC is a public record document that the property owner records before construction starts. It serves as the project's public announcement — telling any potential lienors who the owner is, who the contractor is, and who the lender is, so they know where to send their Notice to Owner.
Think of it as setting up the address directory for the project. Without it, subcontractors and suppliers don't know who to send their NTO to — which can create lien rights disputes.

The NTO — The Sub/Supplier's Document
The Notice to Owner is a document that subcontractors, sub-subcontractors, suppliers, and laborers who do not have a direct contract with the property owner must serve to protect their right to file a mechanics' lien.
Key NTO requirements under § 713.06, F.S.:
- Must be served within 45 days of first furnishing labor, materials, or services
- Must be served on the owner, the general contractor, and the construction lender (if any)
- Can be served by certified mail or other approved methods
- Failure to serve the NTO in time means permanently losing lien rights
Note: The general contractor has a direct contract with the owner and does not need to serve an NTO — they can file a lien directly.
File and Go
The NOC is the owner's document. File and Go handles it — so your lien protection chain starts on solid ground before the first nail goes in.
How the NOC and NTO Work Together
Here's how the two documents function in a typical Florida residential project:
- Owner hires GC → Owner records NOC before construction begins → NOC is posted at job site
- GC hires subcontractors → Subcontractors read the NOC to get the owner's name and address
- Subcontractors serve NTO → Within 45 days of starting work, each sub sends the NTO to the owner, GC, and lender listed on the NOC
- Owner receives NTOs → Owner knows who is on the project and can verify payment before the final draw to the GC
- If the GC fails to pay subs, subs can file a claim of lien — but only if they served the NTO in time
The NOC is what makes the NTO system work. Without the NOC on the public record, subcontractors don't have the owner/lender information they need to serve their NTO properly.
Common Confusions and Mistakes
- Subcontractor files NOC: Subcontractors don't file NOCs — they file NTOs. Only the property owner (or agent) files the NOC.
- Owner ignores NTOs: When an owner receives NTOs, they should track them — these parties have lien rights that attach to the property.
- Missing the 45-day NTO deadline: A subcontractor who waits more than 45 days permanently loses lien rights for work done before the NTO.
