Permit Requirements in Key Biscayne
Know when you need a permit to ensure your project is legal and safe
General Rules
In Key Biscayne and throughout Miami-Dade County, a permit is generally required for most roofing projects. This includes full roof replacements, re-roofing, roof repairs involving structural work, and any modification to the roof deck, sheathing, or framing. Because of Key Biscayne's location in a high-velocity hurricane zone, the county enforces some of the strictest roofing codes in the country.
Permits exist to ensure your roof can withstand extreme weather, protect your property, and meet safety standards. Even minor work that alters the roof's integrity typically requires a permit and inspection.
When Permits Are Required
Permits are typically required for:
- Complete roof replacement or re-roofing (any material change)
- Structural repairs (rafters, trusses, decking, sheathing)
- New roof installations on additions or new construction
- Replacing more than 25% of roof covering in a 12-month period
- Installing sky lights, solar panels, or roof-mounted equipment
- Changing roof shape, pitch, or drainage patterns
- Work that affects fire-rated assemblies
- Commercial roofing involving membrane, metal, or built-up systems
Commercial properties generally require permits for any roof work beyond basic maintenance, including reroofing, repairs affecting structural components, and equipment replacement.
Common Exemptions
Permits may not be required for:
- Minor, non-structural repairs such as patching a small leak (less than a few square feet and not affecting structural components)
- Routine maintenance like clearing gutters or replacing a few shingles if the underlying structure is unaltered
- Replacing roof tiles or shingles in-kind without modifying the deck or underlayment — though this can be a gray area and should be verified
Important: Even if a permit is not technically required, all work must still comply with the Florida Building Code and Miami-Dade County amendments. When in doubt, it's always safer to check with the local building department before starting any roofing work.

Permit Process
Hire a Licensed & Insured Contractor
In Miami-Dade County, only a state-certified or county-registered roofing contractor can pull permits for roofing work. Verify that your contractor holds a valid Florida roofing license and is registered with Miami-Dade County before any work begins.
Submit Plans & Permit Application
Your contractor will submit a permit application to Miami-Dade County's Building Department, typically including a scope of work, product approval documentation (for HVHZ compliance), and wind mitigation calculations. Commercial projects may require engineered plans and sealed drawings.
Plan Review & Approval
The county reviews submitted plans to verify compliance with the Florida Building Code, HVHZ requirements, and local amendments. This review can take anywhere from a few days to several weeks depending on project complexity. Commercial and large residential projects often face longer review times.
Permit Issuance & Scheduling
Once approved, the permit is issued and posted at the job site. Work can then begin. Your contractor should display the permit visibly on the property throughout construction.
Required Inspections
Miami-Dade County requires multiple inspections during a roofing project — typically a rough-in/underlayment inspection before the final roof covering is installed, followed by a final inspection. Your contractor is responsible for scheduling these inspections at the appropriate stages.
Final Approval & Certificate of Occupancy
After all inspections pass, the county issues a final approval. For commercial properties, a Certificate of Occupancy may be required before the building can be used normally. Keep all permit records for future property disclosures and insurance purposes.
Compliance Tips
- ✓ Verify your contractor holds a valid Florida roofing license and is registered with Miami-Dade County before signing any contract.
- ✓ Ask your contractor to include wind mitigation compliance in their scope of work — this can also qualify you for insurance discounts.
- ✓ Never let work begin before the permit is issued and posted on site. Starting without a permit can result in stop-work orders, fines, and even having to tear out completed work.
- ✓ Schedule a pre-construction meeting with your contractor to understand exactly which inspections will be required and who is responsible for scheduling them.
- ✓ Keep a copy of all permit documents, inspection reports, and final approvals. These are valuable for insurance claims, property resale disclosures, and future renovations.
- ✓ If you're in an HOA community, submit your architectural review application at the same time as the permit to avoid delays between approvals.
Special Considerations
HOA Rules
Many Key Biscayne neighborhoods are governed by homeowners' associations (HOAs) with architectural review committees (ARCs) that have additional approval requirements beyond the county permit. HOA rules may govern roof color, material type (e.g., tile vs. metal), and installation timelines. Always check with your HOA before starting — failure to get HOA approval could result in fines or required removal of completed work, even if the county permit was approved.
Zoning
Key Biscayne properties sit within Miami-Dade County's zoning jurisdiction. Setback requirements, height restrictions, and flood zone regulations can all impact roofing projects. Properties in flood zones (common on the island) may require elevation certificates and compliance with floodplain management ordinances. Roof-mounted equipment like solar panels or HVAC units may also face height and visibility restrictions under local zoning codes.
Historic Properties
While Key Biscayne does not have a large designated historic district like some mainland Miami neighborhoods, certain older properties or those near parks and protected areas may have additional review requirements. Miami-Dade County's Historic Preservation Division may have jurisdiction over structures deemed historically significant. Verify with the county if your property is listed or in a potential historic overlay zone.
