Understanding the Notice of Commencement Before You Pay a Contractor in South Florida
If you're hiring a contractor for any significant home improvement project in Florida — a new roof, an AC system, an addition, a kitchen remodel — there's a legal document most homeowners have never heard of that can either protect you from financial disaster or leave you paying for the same work twice. It's called the Notice of Commencement, and in South Florida, where construction fraud and contractor disputes spike every time a hurricane comes through, understanding it before work begins isn't optional. It's one of the most important things you can do as a property owner.
What a Notice of Commencement Actually Is
A Notice of Commencement (NOC) is a legal document recorded with your county clerk's office before construction begins on a project. In Florida, it's required by law under Florida Statute 713.13 for any project where the total contract price exceeds $2,500. The NOC identifies the property owner, the general contractor, the property address, the legal description of the property, the lender (if any), and the scope of work.
Once recorded, it officially opens what's called a "construction lien period" — a window during which any party who performs work or supplies materials to your project has the legal right to file a mechanics' lien against your property if they aren't paid. That includes not just your general contractor, but every subcontractor, supplier, and laborer they bring onto the job.
The NOC must be recorded at the county level — in Miami-Dade, that's the Miami-Dade Clerk of Courts; in Broward, the Broward County Records Division; in Palm Beach County, the Clerk & Comptroller's office; and in Monroe County, the Monroe County Clerk of Court. It must also be posted visibly at the job site before the first inspection.
One notable exception: Florida law raises the NOC threshold to $15,000 for direct HVAC equipment replacements that don't involve structural or electrical changes beyond the unit itself. If you're replacing a like-for-like AC unit with no additional work, confirm with your contractor whether this exemption applies — though when in doubt, recording an NOC anyway protects you at minimal cost.
Why This Matters More in South Florida Than Almost Anywhere Else
Florida's construction lien laws are among the strongest in the country when it comes to protecting subcontractors and suppliers — which is good for them, but creates a real risk for property owners who don't understand the system.
Here's the scenario that catches South Florida homeowners off guard every year, particularly in the months after a hurricane: you hire a general contractor, pay them in full, and consider the job done. What you may not know is that your contractor hired a roofing subcontractor, an electrical sub, and a materials supplier — and paid none of them. Under Florida law, those unpaid parties can file a lien against your property even though you already paid your contractor. You paid once and still owe again, because the money never reached the people who actually did the work.
This is not a hypothetical. The Florida Attorney General's office consistently lists contractor fraud among the top consumer complaints received after major storm events, and the mechanics' lien system is the primary vehicle through which that fraud plays out. In Miami-Dade and Broward counties, where post-storm demand for roofing and structural contractors routinely exceeds supply, the conditions for this kind of dispute are essentially built into the market.
The Notice to Owner (NTO): What It Means When You Receive One
Closely related to the NOC is the Notice to Owner (NTO) — and as a homeowner, you don't send this document, you receive it. Subcontractors and material suppliers serve the NTO to you to notify you that they are working on your project and have established lien rights against your property.
Florida law requires most subcontractors and suppliers to serve you with a Notice to Owner within 45 days of first furnishing labor or materials to your project in order to preserve their lien rights. If they don't send it within that window, they lose the right to lien your property.
Receiving an NTO is not a red flag — it's actually a good sign that the subcontractors on your job are following the law and protecting their rights properly. What you should do when you receive one is keep a record of it, confirm with your general contractor that those parties are being paid on schedule, and request lien waivers (more on that below) as the project progresses.
Lien Waivers: Your Main Protection
A lien waiver is a document signed by a contractor, subcontractor, or supplier stating that they have received payment and waive their right to file a lien for the amount paid. In Florida, there are four statutory lien waiver forms defined under Florida Statute 713.20:
- Partial Release of Lien (Conditional): Waives lien rights for a specific payment, contingent on the payment actually clearing.
- Partial Release of Lien (Unconditional): Waives lien rights for a specific payment, effective immediately upon signing.
- Final Release of Lien (Conditional): Waives all lien rights, contingent on final payment clearing.
- Final Release of Lien (Unconditional): Waives all lien rights permanently, effective immediately.
Before releasing any payment to your general contractor — especially a final payment — request a conditional lien waiver from every party on your NTO list. Before releasing the final payment, get unconditional final releases from everyone. This is the single most effective way to protect yourself from paying twice.
The $2,500 Threshold and What Triggers an NOC in South Florida
Florida's $2,500 threshold applies to the total contract price, not the cost of materials or labor separately. In South Florida, where even a straightforward bathroom update can exceed that number before a tool touches the wall, virtually every permitted project will require one.
In Miami-Dade County specifically, the county's Regulatory and Economic Resources (RER) department requires the recorded NOC to be on file before issuing a building permit for the covered work. The county's eCPM (electronic City Permitting and Monitoring) system tracks this requirement, and contractors familiar with Miami-Dade's permitting process know that no inspection will be scheduled without it properly posted at the job site.
Coral Gables adds another layer — its Architectural Review Board (ARB) requirements mean certain exterior modifications require ARB approval before a permit can even be pulled. In Brickell and other high-rise residential areas, HOA insurance minimums and building management approval processes add additional steps before work can begin, separate from the statutory NOC requirement.
In the Florida Keys (Monroe County), seasonal contractor availability, permitting timelines, and the logistical reality of working on an island chain make the NOC window particularly important — delays in posting or recording can push a project back weeks during peak season.

What to Do Before Work Starts
Before any contractor breaks ground on a project at your South Florida property, confirm the following:
- Verify the NOC has been recorded with your county clerk and that the recording information (book and page number) is available.
- Confirm the NOC is posted at the job site before the first inspection — this is a permit requirement in Miami-Dade and most South Florida municipalities.
- Ask your contractor for a list of all subcontractors and suppliers they plan to use on the project.
- Track your NTO receipts and keep them organized by party and date received.
- Request lien waivers at each payment milestone and file them with your project records.
- Verify your contractor's license through the Florida DBPR before signing any contract — an unlicensed contractor has no legal standing on your property and creates additional lien and liability exposure.
Understanding these steps doesn't require a law degree. It requires knowing the system exists, and knowing what to ask for before you write the first check. ```
