A Notice of Commencement (NOC) is a short recorded document that Florida’s Construction Lien Law requires before most construction projects begin — and skipping it, or letting it lapse mid-project, is one of the more common (and avoidable) ways a homeowner ends up exposed to paying twice for the same work.
What it is and why it exists
An NOC formally puts the public — and specifically, anyone who might supply labor or materials to the job — on notice that a construction project is underway on a specific property. It’s part of the mechanism that governs construction (mechanic’s) liens in Florida: it starts the clock on the “Notice to Owner” process that subcontractors and suppliers use to protect their right to file a lien if they aren’t paid, and it establishes priority among any liens that do get filed.
Without a properly recorded NOC on a project that requires one, an owner can end up legally exposed to a subcontractor’s lien claim even after paying the general contractor in full — commonly described as the risk of “paying twice.”
When it’s required
An NOC is generally required for construction work valued above $2,500 — a threshold that covers the large majority of permitted renovation, addition, and new-construction projects. Direct-contracted HVAC work has its own higher threshold, $7,500. Because most permitted jobs exceed the general threshold, building departments routinely require a certified copy of the recorded NOC as a condition of scheduling the first inspection — see the relevant jurisdiction’s building department through RefPages’ Building Permit Departments directory.
Where and how to file it
The NOC is recorded with the Clerk of Court in the county where the property is located — the same office that records deeds, mortgages, and liens, linked for every Florida county through RefPages’ County Records directory. After recording:
- Obtain a certified copy of the recorded NOC from the Clerk.
- Post the certified copy at the job site, typically near the permit itself, where it’s visible.
- Provide a copy to the building department, generally before the first inspection is scheduled.
What it needs to include
A valid NOC generally identifies:
- The property’s legal description and address
- The owner’s name and address, and their interest in the property
- The contractor’s name and address
- The lender, if the project is financed, and any surety/bond information
- An expiration date, if different from the statutory one-year default
It expires — and that matters mid-project
An NOC is valid for one year from the date it’s recorded, unless it states an earlier expiration date or is formally amended to extend it. On a project that runs long — which is common with permitting delays, material backorders, or scope changes — it’s worth tracking that expiration date directly. If it lapses while work is still underway, the project can lose the lien-priority protection the NOC was providing, and some building departments will hold up further inspections until a current NOC is on file.
Why this matters for insurance and resale
An NOC on file (or its absence) is part of the documentation trail an insurer or title company may look for when evaluating recent work on a property — alongside the closed permit itself and, where relevant, confirmation of the contractor’s license. Missing or lapsed NOC paperwork on a renovation is the kind of gap that surfaces at the worst time: during a claim, or during a sale when a title search turns up an unresolved construction lien.
