Florida building permit exemptions are set by Section 105.2 of the Florida Building Code, which lets homeowners skip the permit process for a defined list of minor projects: one-story sheds of 120 square feet or less, most fences up to 7 feet, storable above-ground pools, painting and other cosmetic finish work, short retaining walls, low sidewalks and driveways, playground equipment, and small window awnings. Two separate carve-outs sit alongside that list: genuine farm buildings under Florida Statute 604.50 and owner-builders working on their own home under Florida Statute 489.103. None of these exemptions release you from the underlying code, from local overlays, or from federal rules, and getting the line wrong can end in a stop-work order, a denied insurance claim, or a stalled sale.
What Section 105.2 Actually Exempts
The code lists the categories precisely. If your project doesn’t fit inside one, you need a permit.
- One-story detached accessory structures such as sheds and playhouses, with a floor area of 120 square feet or less.
- Fences not over 7 feet high, provided they aren’t serving as a swimming pool barrier.1Miami-Dade County. Permit Exemptions
- Storable swimming and wading pools built on or above the ground holding water no deeper than 42 inches, and pools with nonmetallic molded or inflatable walls regardless of size. Any electrical connection beyond a standard cord-and-plug hookup still needs a permit.2Lake County FL. Residential Work Exempt From Permits
- Painting, wallpapering, tiling, carpeting, cabinetry, countertops, and similar cosmetic and finish work.1Miami-Dade County. Permit Exemptions
- Concrete sidewalks and driveways no more than 30 inches above surrounding grade, not over a basement, and not part of an accessible route.
- Retaining walls 4 feet or shorter measured from the bottom of the footing, unless they support a surcharge or hold back certain liquids.
- Playground equipment on single-family or two-family residential property.
- Window awnings attached to a residence that project no more than 54 inches and need no additional support.
Skipping a permit is not the same as skipping the code. Exempt work still has to meet the technical requirements, and it still has to comply with local zoning rules on setbacks, height, coverage, and appearance.
The Pool Trap
The pool exemption confuses more homeowners than any other item on the list. It covers storable pools only: above-ground, water 42 inches or shallower, or pools with nonmetallic molded or inflatable walls. In-ground pools, hot tubs, and permanent spas need a full building permit regardless of depth. And an exempt storable pool still has to satisfy the local barrier and safety fencing rules, and that barrier itself may require its own permit.
Where Local Limits Are Stricter
Some counties trim the statewide numbers. Fence limits sometimes drop to 6 feet for standard fences and 4 feet for masonry walls. The state exemption is a ceiling on what the code demands; your local building department can still demand less. Call before you build.
Farm Building Exemption
Florida Statute 604.50 exempts nonresidential farm buildings, farm fences, and farm signs on genuine agricultural land from the Florida Building Code and from county or municipal building codes and fees. The category is broad: barns, greenhouses, shade houses, farm offices, storage buildings, poultry houses, and similar structures qualify as long as they’re used primarily for agricultural purposes and are not a residence. The land has to be classified as agricultural under Florida’s agricultural assessment statute or be an integral part of a farm operation.3Official Internet Site of the Florida Legislature. Florida Statutes 604 – General Agricultural Laws – Section 604.50
Two limits matter. Urban agriculture doesn’t qualify. And the exemption does not override floodplain management rules at any level of government, so a farm building in a FEMA flood zone still has to meet floodplain requirements. Using the exemption for a structure that isn’t genuinely agricultural in purpose can trigger code enforcement and retroactive permitting.
Building on Your Own Home Without a Contractor
Florida Statute 489.103 lets a property owner act as their own contractor on a one-family or two-family residence they plan to live in, provided they directly supervise onsite any work not handled by licensed subcontractors. The same statute covers farm outbuildings and commercial buildings on property you own and occupy, but commercial projects are capped at $75,000 in construction cost. The house you build under this exemption cannot be offered for sale or lease; if you list it right after finishing, that sale becomes evidence you were acting as an unlicensed contractor.4Official Internet Site of the Florida Legislature. Florida Statutes 489 – Contracting – Section 489.103
This is a contractor-licensing exemption, not a permit exemption. You still pull the permits your project requires, and the work still passes inspection. You’re just running the project instead of paying a general contractor to do it.
Some trade work also stays out of the owner’s hands. Electrical work beyond basic cord-and-plug connections is exempt from a permit only when it qualifies as minor repair; anything more requires both a permit and a licensed electrical contractor. Plumbing and gas work follow the same pattern. Hiring an unlicensed person to do licensed work can void the exemption and leave the homeowner liable for injuries or code violations.

When Local Rules Override the State Exemption
Counties and municipalities can adopt local technical amendments that tighten the code beyond the statewide baseline.6Official Internet Site of the Florida Legislature. Florida Statutes 125 – County Government – Section 125.56 An exemption that works in one county may not survive in the next.
The most significant example is the High-Velocity Hurricane Zone covering Miami-Dade and Broward Counties. Buildings there must meet stricter wind-resistance standards under a dedicated section of the Florida Building Code, and projects that would be routine elsewhere may need additional engineering, upgraded materials, and product approvals specific to the HVHZ. Coastal areas throughout the state also stack on flood zone rules, sea turtle lighting ordinances, and coastal construction control line setbacks. A project that skips a Section 105.2 building permit may still need a local zoning permit or environmental review.
Federal Rules the Exemption Doesn’t Touch
The FEMA 50 Percent Rule
If your property is in a FEMA-designated flood zone and your renovation costs equal or exceed 50 percent of the building’s pre-work market value, the entire structure has to be brought into compliance with current floodplain management standards, which usually means elevating it to or above the base flood elevation. The cost calculation includes materials, labor, built-in appliances, and contractor overhead and profit; it excludes plan preparation, surveying, permit fees, emergency health-and-safety repairs, and work on items outside the building like driveways and fences. The denominator is the market value of the structure alone, not the land. In older Florida homes, this threshold is easier to cross than people expect, especially after storm damage.7FEMA. Substantial Improvement and Substantial Damage
Lead Paint in Pre-1978 Homes
Any renovation, repair, or painting project that disturbs lead-based paint in a home built before 1978 triggers the federal Renovation, Repair, and Painting rule. The work has to be performed by an EPA-certified renovator using lead-safe practices, even when the project is otherwise exempt from a Florida building permit.8US EPA. Lead Renovation, Repair and Painting Program Painting is on the Section 105.2 exempt list; in an older home, the RRP rule still applies.
If Your Project Is Permitted, File the Notice of Commencement
For work that does require a permit, Florida requires a notice of commencement recorded with the county clerk before construction starts. The document identifies the owner, contractor, surety on any payment bond, and construction lender, along with the property description and a general description of the work. It has to be recorded before the first inspection and posted at the job site. Miss this and you leave yourself exposed to subcontractor liens; many building departments also won’t schedule that first inspection until they see the recorded notice, so the project stalls on day one.9Florida Senate. Florida Statutes 713 – Mechanics Liens – Section 713.13
What Happens If You Skipped a Permit You Needed
The consequences run from inconvenient to severe depending on when the violation surfaces.
Stop-Work Orders
A building official who finds noncompliant construction that threatens public safety can issue a stop-work order halting part or all of the project.10Official Internet Site of the Florida Legislature. Florida Statutes 553 – Building Construction Standards – Section 553.791 Crews leave, deliveries cancel, and construction-loan interest keeps running. Restarting often requires tearing out completed work, hiring an engineer to evaluate what was built, and pulling the permits retroactively.
After-the-Fact Permits
Most Florida jurisdictions will let you legalize unpermitted work through a retroactive permit. Expect to hire a professional to produce as-built drawings, submit them for plan review, correct anything that doesn’t meet current code, and pass all required inspections. Fees are typically higher than they would have been up front. Coming forward before code enforcement finds the work usually helps on penalties, but bringing older construction up to today’s code can be expensive.
Selling Later
Unpermitted work is a recurring problem at closing. Once you know about it, failing to disclose exposes you to legal liability, and buyers who discover it after closing may have recourse against the seller. Title companies and lenders increasingly flag permit discrepancies during due diligence, and appraisers may exclude unpermitted square footage from the valuation. Homes with known unpermitted work often sell at a discount or force the seller to legalize the work before closing.
Insurance and Tax Fallout
Insurers can deny claims tied to unpermitted construction. If a fire starts in a room addition that was never permitted or inspected, the carrier can argue the work didn’t meet code and refuse to pay. Some carriers cancel or refuse to renew a policy after discovering unpermitted work during an inspection. Permit-exempt work can still cause claim problems if it wasn’t built to code, because exemption from permitting is not exemption from code compliance. Check with your carrier before starting anything significant.
On the tax side, Florida Statute 193.1555 reassesses a property at full just value the following January 1 when improvements increase just value by 25 percent or more.11Official Internet Site of the Florida Legislature. Florida Statutes 193 – Assessments – Section 193.1555 Routine repairs that restore existing condition generally don’t count as improvements; added square footage, a garage conversion to living space, or a substantial new structure typically does. Most permit-exempt work stays well below the threshold, but larger projects on the maintenance-versus-improvement line can trip it.
