Florida's building permit system exists for important reasons — hurricane resilience, structural safety, and electrical and plumbing code compliance. But many homeowners skip permits to save time or money, not understanding that unpermitted work becomes their problem (and their buyer's problem) at resale. Here's what actually requires a permit in Florida, how the process works, and what happens if you skip it.
What Requires a Permit in Florida
Under the Florida Building Code, a permit is required for any work that involves structural, mechanical, electrical, or plumbing systems. Specifically:
- Roofing: Any full replacement or tear-off. Patch repairs under 25% of the total roof area in some jurisdictions may not require a permit — but full re-roofs always do.
- Electrical: New circuits, panel upgrades, service changes, adding outlets or fixtures in finished spaces, EV charger installation, generator transfers. Simple fixture replacements (same box, same wiring) typically don't require permits.
- Plumbing: New supply or drain lines, water heater replacement in some jurisdictions, moving fixtures, gas line work. Replacing a faucet or toilet doesn't require a permit.
- HVAC: New system installation or full replacement almost always requires a permit. Duct cleaning, filter replacement, and minor repairs (capacitor, thermostat) typically don't.
- Structural work: Adding or removing walls (load-bearing or not in some jurisdictions), adding rooms, garage conversions, carports, decks, patios over a certain size.
- Windows and doors: Replacement windows and doors in Florida almost always require a permit (hurricane impact ratings must be verified). Simple glass replacement in the same frame may not.
- Pools and spas: Always permitted.
- Fences: Permit required in most Florida jurisdictions over a certain height (typically 6 feet).
What Typically Doesn't Require a Permit
- Painting (interior or exterior)
- Flooring installation (tile, LVP, carpet) over existing subfloor
- Cabinet replacement (same footprint, no plumbing changes)
- Countertop replacement
- Fixture swaps (faucets, toilets, light fixtures in existing boxes)
- Appliance replacements (range, dishwasher, refrigerator) — unless gas line work involved
- Landscaping and irrigation (in most jurisdictions; some counties require irrigation permits)
The Florida Permit Process
- Plans submission: Licensed contractor submits plans to the local building department. For major projects, engineered drawings may be required — especially in hurricane-prone areas where structural designs must be stamped by a PE.
- Plan review: Takes 1–8 weeks depending on jurisdiction complexity and backlog. Miami-Dade and Broward are slowest.
- Permit issuance and posting: Permit must be posted visibly on site during construction.
- Inspections: Required at various project stages (rough-in, framing, insulation, final). Contractor must schedule each inspection and work may not proceed past each stage until the inspector signs off.
- Certificate of Completion / Occupancy: Final sign-off closes the permit. This document is your proof that work was done to code.
Consequences of Unpermitted Work
- Disclosure at sale: Florida law requires sellers to disclose known material defects, including unpermitted work. Lying about it creates legal liability.
- Insurance issues: Unpermitted roofs and electrical systems can void homeowners insurance coverage for related claims.
- Lender problems: Buyers' lenders may require unpermitted work to be remediated before funding. This can kill deals or add $10,000–$50,000 in remediation costs to the seller.
- Open permit issues: Sometimes the previous owner pulled a permit that was never closed out (no final inspection). This becomes the current owner's problem — you must get the work inspected and the permit closed before selling or pulling new permits in most jurisdictions.
Retroactive Permits: Legalizing Unpermitted Work
If you discover unpermitted work on a property you own (or are buying), a retroactive permit is possible in most Florida jurisdictions — but requires exposing the work for inspection, which may mean opening walls or ceilings. Cost varies widely. For structural or electrical unpermitted work, a retroactive permit often costs more than doing it correctly the first time.
