What Requires a Building Permit in Florida: Exemptions and Penalties

In Florida, almost any construction, alteration, repair, demolition, or change of use of a building requires a permit from your local city or county building department before work begins, along with permits for electrical, plumbing, mechanical, and gas system work. The Florida Building Code applies statewide, but local building departments review the plans, issue the permits, and send the inspectors, and they can impose stricter requirements than the state minimum.¹ Starting work without a required permit is unlawful under Florida law.²

The Default Rule

The Florida Building Code casts a wide net. Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish, or change the occupancy of a building must apply for and receive a permit first. The same applies to installing or replacing any electrical, gas, mechanical, or plumbing system regulated by the code.³ A separate statute makes it unlawful for any person, company, or government entity to do any of that work without a permit from the enforcing agency.²

If the project touches the structure itself, changes how a space is used, or involves a life-safety or regulated system, assume a permit is required. The exemptions are specific and limited.

Projects That Require a Permit

Because the default is “permit required,” the covered list is long. The categories homeowners and contractors run into most often:

New construction. A new home, garage, carport, or any detached structure.
Additions and enclosures. Adding a room, enclosing a porch or lanai, or expanding a building’s footprint.
Structural changes. Removing or modifying a load-bearing wall, cutting new window or door openings, or reinforcing framing.
Roof replacement. Full re-roofing and substantial roof repairs. Florida insurers and lenders watch roof permits closely because of hurricane exposure.
Electrical work. New wiring, panel upgrades, added circuits, or a generator transfer switch.
Plumbing work. Re-piping, relocating lines, or installing a new water heater.
HVAC systems. Installing or replacing an air conditioning unit, furnace, or ductwork.
Swimming pools and spas. All pool construction, including the required safety barriers and decking.
Impact-resistant coverings. Hurricane shutters and impact windows are specifically called out in the code as requiring a permit.³
Taller fences. Most jurisdictions require a permit for fences above six feet; some set the threshold lower depending on zoning.
Sheds and small detached structures above a size threshold. Typically once they exceed 100 to 120 square feet, depending on local rules.
Demolition. Tearing down a structure or a significant portion of one.
Change of occupancy. Converting a garage into a bedroom, or a residence into a commercial office, for example.

One category that surprises many homeowners: driveway and paving work that changes impervious surface area or affects drainage. Florida’s stormwater rules mean hardscaping can trigger local permit and review requirements too.

Work That Does Not Require a Permit

The exemptions in Section 105.2 of the Florida Building Code are narrow. They cover genuinely minor work that does not affect a building’s structure, fire safety, or regulated systems. Exempt work still has to comply with the code; you just skip the permit and inspection process.

Cosmetic and Finish Work

Painting, wallpapering, installing tile or carpet, and similar finish work are generally exempt. You can replace cabinets and countertops without a permit as long as you are not relocating plumbing, gas, or electrical connections.

Ordinary Minor Repairs

The code allows “ordinary minor repairs” without a permit, but the definition is tighter than most people assume. Minor repairs cannot involve cutting into any wall or partition, removing or cutting any structural beam or load-bearing support, changing any means of egress, or touching any standpipe, water supply, sewer, drain, gas, vent, electrical, or mechanical system.⁴ Replacing a broken window pane or patching drywall qualifies. Cutting a new opening in a wall does not.

Plumbing

You can clear a clogged drain or fix a leaking pipe, valve, or fixture without a permit, and you can remove and reinstall a toilet. Once the repair requires replacing or rearranging valves, pipes, or fixtures, it crosses into permit territory.⁴ Swapping a faucet in the same location is fine. Moving a sink to a different wall is not.

Simple Electrical Replacements

Replacing a light fixture or outlet with a similar one, without altering the underlying wiring, does not require a permit. The same goes for replacing a lamp or connecting portable equipment to an existing outlet. Panel upgrades and new circuits always require a permit.

Small Detached Structures

Small storage sheds and similar detached structures are often exempt, but the size threshold depends on your jurisdiction. Some counties set the limit at 100 square feet, others at 120. If you are close to the line, check with your building department before starting.

Doing the Work Yourself: Owner-Builder Rules

Florida law lets property owners act as their own general contractor under specific conditions, but the owner-builder exemption does not exempt you from the permit process. You still pull the permit and schedule the same inspections. You, rather than a licensed contractor, become the responsible party of record.

To qualify, you must own the property and provide direct, on-site supervision of all work that is not performed by licensed subcontractors. The work must be for your own use and occupancy. The exemption covers a one-family or two-family residence, a farm outbuilding, or a commercial building costing no more than $75,000.⁵

The critical restriction: if you sell or offer the property for sale or lease within one year of completing the work, the law presumes you built it for sale, which violates the exemption.⁵ Investors planning to flip a property should use a licensed contractor.

Before issuing a permit to an owner-builder, most local building departments require a signed disclosure statement. You will need to prove ownership, certify competence to supervise the work, and acknowledge personal liability for code compliance and for any injuries to unlicensed workers on site.

What Happens If You Skip the Permit

Working without a required permit is not a technical paperwork problem. It creates a chain of consequences that gets more expensive the longer it goes unresolved.

Stop-Work Orders and Fines

If a building official discovers unpermitted work in progress, the official can issue a stop-work order halting construction immediately. The order must state the reason and the conditions under which work can resume.⁶ Continuing to work after a stop-work order can escalate to criminal charges.

Local governments set their own fine schedules for building code violations. Penalties can include per-day fines for each day the violation continues, plus recovery of enforcement costs such as inspection fees, report preparation, and attorney’s fees. Some local codes classify building code violations as misdemeanors punishable by fines and up to 60 days in jail.

After-the-Fact Permits

To legalize work you already completed, you will need an after-the-fact permit. Most jurisdictions charge a penalty fee, commonly double the standard permit fee. In Miami, homestead properties pay double the normal fee plus a $110 surcharge, while non-homestead and commercial properties pay four times the normal fee plus the surcharge.⁷ There is no guarantee the building official will approve the work as built. You may be required to open walls, expose framing, or redo work that does not meet code.

Insurance Problems

Unpermitted work can undermine your homeowners insurance in ways you will not discover until you file a claim. If damage is connected to unpermitted work, an insurer may deny the claim on the grounds the work was never inspected and may not meet code. Some insurers exclude coverage for portions of a home with known unpermitted improvements; others cancel policies or refuse renewal after discovering unpermitted work during an inspection. Florida insurers frequently require four-point inspections for older homes, covering the roof, electrical, plumbing, and HVAC systems. If any of those systems were installed without permits, coverage can be declined or restricted.

Trouble When Selling

Unpermitted work becomes a problem at closing. Buyers’ lenders and inspectors routinely flag additions or improvements that do not match the property’s permit history. Florida sellers are expected to disclose unpermitted work, and failing to do so can expose you to legal action for the cost of permits, code-compliance repairs, and the buyer’s legal fees. Even with disclosure, many buyers demand a price reduction or require after-the-fact permits before closing.

How to Confirm Before You Start

The safest approach is to assume you need a permit and check with your local building department before any work begins. Contact the city building department if your property is within city limits, or the county building department if you are in an unincorporated area. Most departments accept inquiries by phone, email, or through their website, and many offer online permit guides or searchable permit databases.

Have the property address, a description of the work, and the full scope of the project ready. “I’m replacing my water heater” is a different conversation than “I’m moving my water heater to the garage and running new gas lines.” The more specific you are, the more useful the answer.

If you are hiring a contractor, the contractor should be pulling the permit in most cases. Be wary of any contractor who suggests skipping the permit to save time or money. That shortcut shifts the risk onto you as the property owner, and the consequences do not go away just because someone else did the work.
