A Florida impact-window or door replacement can involve more than a building permit.
Depending on the project value and circumstances, the homeowner may also need to record a Notice of Commencement, commonly called an NOC, before the first inspection.
The NOC is part of Florida’s Construction Lien Law. It is not a product approval, engineering document, or inspection form.
What is a Notice of Commencement?
Florida Statutes section 713.13 establishes the Notice of Commencement process for improvements to real property.
The notice identifies information such as the property, owner, contractor, lender when applicable, and other parties associated with the improvement.
Its purpose is tied to Florida’s construction-lien framework.
When can an NOC apply to a window replacement?
Local building departments commonly require a recorded NOC when the project exceeds the applicable statutory threshold.
Miami-Dade’s current guidance states that a Notice of Commencement is required for real-property improvements greater than $5,000, subject to the statutory exceptions.
Pompano Beach and Hillsborough County publish the same general $5,000 threshold for improvements.
Because procedures can vary by permitting authority, verify the current requirements for the actual property before the first inspection.
When must it be recorded?
Florida Statutes section 713.135 requires the permit card to warn owners that a Notice of Commencement must be recorded and posted on the job site before the first inspection when it applies.
That timing matters.
A permit can be issued before the first inspection while the NOC is still being finalized, depending on local procedure, but the homeowner should not assume the inspection can proceed without it.
Does the contractor record it automatically?
Do not assume so.
The owner or authorized agent should confirm:
- Who is preparing the NOC
- Who will sign it
- Where it will be recorded
- Whether a certified copy is required
- Whether it must be uploaded into the permit portal
- Whether it must be posted at the property
Ask these questions before installation begins.
Why does the NOC matter to the homeowner?
Florida’s permit warning is direct: failing to record a required NOC can create lien-related risk.
That does not mean every payment dispute results in a lien.
It means the NOC is part of the legal process that helps define the parties and timeline for the improvement.
For legal questions about a specific contract or lien situation, speak with a Florida attorney.
Is a separate NOC needed for every permit?
Some jurisdictions explicitly require a separate Notice of Commencement for each permit.
Miami-Dade’s current guidance states that a separate NOC must be filed for each individual permit issued.
If your window-and-door project has multiple permits, confirm the local requirement instead of assuming one NOC covers everything.
What information should you keep?
Keep a project file containing:
- Recorded Notice of Commencement
- Permit application
- Permit number
- Contract
- Product approvals
- Window/door schedule
- Approved revisions
- Inspection results
- Final permit closeout
- Payment records
- Warranty documentation

Frequently asked questions
Is a Notice of Commencement the same as a building permit?
No. They are different documents serving different purposes.
Does every Florida window project require an NOC?
Not necessarily. Applicability depends on the project and current statutory/local requirements.
Does the NOC need to be recorded before the first inspection?
Florida’s permit warning states that a required Notice of Commencement must be recorded and posted before the first inspection.
Can I rely only on the contractor to handle it?
You should verify that the required document has actually been recorded and accepted for the permit.
