Florida building permit exemptions are set out in Section 105.2 of the Florida Building Code, which lets you skip the permit application and inspection process for a short list of minor projects: small detached sheds, fences up to 7 feet, storable above-ground pools, cosmetic finish work, low retaining walls, residential playground equipment, short driveways, and a few similar items. Separate statutes exempt genuine farm buildings and let property owners act as their own contractor on their own home. None of these exemptions excuse you from complying with the code itself, from local ordinances, from federal rules, or from the consequences if your insurance company or a future buyer finds out the work wasn’t done right.
Projects That Don’t Need a Permit
The exemptions in Section 105.2 that come up most often for homeowners are narrow and specific. If your project doesn’t fit the description precisely, assume you need a permit.
- One-story detached accessory structures (sheds, playhouses, and the like) with a floor area of 120 square feet or less.
- Fences not over 7 feet high, as long as they aren’t acting as a swimming pool barrier.1Miami-Dade County. Permit Exemptions
- Storable swimming and wading pools that sit on or above the ground and hold water no deeper than 42 inches, plus nonmetallic molded or inflatable-wall pools 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, cabinets, countertops, and similar finish work.1Miami-Dade County. Permit Exemptions
- 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.
- Swings and similar playground equipment on single-family or two-family residential properties.
- Window awnings attached to a residence that project no more than 54 inches and need no extra support.
The swimming pool exemption is the one most people get wrong. It only covers storable pools that sit on or above the ground. Any in-ground pool, hot tub, or permanent spa needs a full building permit regardless of depth, and even an exempt storable pool still has to meet local barrier and safety-fencing rules, which may themselves require a separate permit.
Skipping the permit never means skipping the code. The work still has to meet applicable code requirements, and other rules such as zoning setbacks, HOA restrictions, and local ordinances apply as they normally would.
Farm Buildings on Agricultural Land
Florida Statute 604.50 exempts nonresidential farm buildings, farm fences, and farm signs on genuinely agricultural land from the Florida Building Code and from county or municipal building codes and fees.3Official Internet Site of the Florida Legislature. Florida Statutes 604 – General Agricultural Laws – Section 604.50 The definition is broad: barns, greenhouses, shade houses, farm offices, storage buildings, poultry houses, and similar structures all qualify so long as they are used primarily for agricultural purposes and aren’t intended as a residence. The land must be classified as agricultural under Florida’s agricultural assessment statute or be an integral part of a farm operation.
Two limits matter. Urban agriculture does not qualify. And the exemption does not override floodplain management regulations at any level of government, so a farm building in a FEMA flood zone still has to meet floodplain rules. Using the agricultural exemption for a structure that isn’t genuinely agricultural can lead to code enforcement action and retroactive permitting.
Doing the Work Yourself as an Owner-Builder
Florida Statute 489.103 lets property owners act as their own contractor when building or improving a one-family or two-family residence they plan to live in, provided they directly supervise onsite any work not handled by a licensed subcontractor.4Official Internet Site of the Florida Legislature. Florida Statutes 489 – Contracting – Section 489.103 The same exemption covers farm outbuildings and commercial buildings on property you own and occupy, with commercial projects capped at $75,000 in construction cost. You can’t offer the residence for sale or lease: listing it right after you build it is itself treated as evidence that you were acting as an unlicensed contractor.
This is a licensing exemption, not a permit exemption. You still have to pull every permit the code requires, and the work still has to pass inspection. You’re only allowed to run the project yourself instead of hiring a general contractor.
Local Rules Can Override the Statewide Exemption
The Florida Building Code is the baseline. Counties and municipalities can adopt local technical amendments that go beyond it, which means an exemption that works in one jurisdiction may be narrower or unavailable in another.5Official Internet Site of the Florida Legislature. Florida Statutes 125 – County Government – Section 125.56 Some counties cut the exempt fence height to 6 feet, or 4 feet for masonry walls.
The biggest 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 code, and projects that would be routine elsewhere in Florida can require additional engineering, upgraded materials, and HVHZ-specific product approvals. Coastal areas throughout the state layer on flood zone management rules, sea turtle lighting ordinances, and setbacks from the coastal construction control line. A project that doesn’t need a building permit under Section 105.2 can still need a zoning permit or environmental review from the local jurisdiction.
Call your local building department before you rely on any state-level exemption as written.
Federal Rules Still Apply
FEMA’s 50 Percent Rule
If your property is in a FEMA-designated flood zone and the cost of your renovation equals or exceeds 50 percent of the building’s market value before the work begins, the entire structure must be brought into compliance with current floodplain management standards. That usually means elevating it to or above the base flood elevation.6FEMA. Substantial Improvement and Substantial Damage The cost calculation includes materials, labor, built-in appliances, contractor overhead, and profit; it excludes plan preparation, surveying, permit fees, demolition and emergency repairs for health and safety, 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 in flood zones, the 50 percent threshold is easier to hit than owners expect, especially when storm repairs are already underway.
EPA Lead Paint Rule
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 must be done by an EPA-certified renovator using lead-safe practices, even if the project is otherwise exempt from a Florida building permit.7US EPA. Lead Renovation, Repair and Painting Program Interior painting is on the Section 105.2 exempt list, but that doesn’t help you here.
What You Still Owe Even When Exempt
Code compliance. No permit exemption excuses you from the underlying code. If the work is defective and later causes damage, “it was exempt” is not a defense.
Licensed trades. Some permit exemptions only hold if the work is minor. Electrical work beyond basic cord-and-plug connections is exempt only when it qualifies as minor repair; anything more needs both a permit and a licensed electrical contractor. Plumbing and gas follow the same pattern. Hiring an unlicensed person to do work that requires a license voids the exemption and can leave you liable for resulting injuries or code violations, while the unlicensed worker faces criminal penalties under Florida’s contracting statutes. You can confirm a contractor’s license at MyFloridaLicense.com in about 30 seconds.8Department of Business and Professional Regulation. MyFloridaLicense.com – License Efficiently. Regulate Fairly.
Insurance. Carriers may deny claims tied to unpermitted construction. If an electrical fire starts in an addition that was never permitted or inspected, the insurer can argue the work didn’t meet code and refuse the claim. Some carriers will cancel or non-renew a policy after discovering unpermitted work. Permit-exempt work can create the same problem if it wasn’t done to code.
Property tax reassessment. Under Florida Statute 193.1555, improvements that increase a property’s just value by 25 percent or more trigger a reassessment at full just value as of January 1 of the following year.9Official Internet Site of the Florida Legislature. Florida Statutes 193 – Assessments – Section 193.1555 Routine repairs that just restore existing condition generally don’t count as improvements, but adding square footage, converting a garage to living space, or putting up a substantial new structure likely does. Most permit-exempt work stays well under the threshold; larger projects that straddle maintenance and improvement can surprise you.
What Happens If You Skip a Permit You Actually Needed
A building official who finds construction that doesn’t comply with applicable codes and poses a threat to 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 Workers leave, deliveries get canceled, and loan interest keeps running. Resuming often requires tearing out completed work, hiring an engineer to evaluate what was built, and pulling the proper permits retroactively.
Most Florida jurisdictions allow an after-the-fact permit. The process typically means hiring a professional to prepare as-built drawings, submitting them for plan review, making any corrections needed to meet current code, and passing all required inspections. Fees run higher than they would have if you had applied up front. Coming forward voluntarily tends to produce a better outcome than being caught, but bringing non-compliant work up to current standards can be expensive.
Unpermitted work also follows you to the closing table. Florida requires sellers to provide a disclosure summary to prospective buyers, and once you know about unpermitted construction, failing to disclose it exposes you to legal liability. Buyers who discover undisclosed unpermitted work after closing may have recourse against the seller, especially where information was concealed or misrepresented. Title companies and lenders increasingly flag permit discrepancies during due diligence, and appraisers may discount or exclude unpermitted square footage entirely. Homes with known unpermitted work often sell at a discount or force the seller to legalize the work before closing.
