Florida building permit requirements apply to nearly any construction, renovation, demolition, or system replacement on residential or commercial property, and the permit must be issued by the local building department before work begins. The rules come from the Florida Building Code, which is enforced locally but set statewide, so the process looks broadly similar whether you’re in Miami-Dade or the Panhandle. What changes from county to county is fees, forms, and some size thresholds for exemptions.
What Work Requires a Permit
Florida law makes it unlawful to build, alter, repair, move, or demolish any building without first obtaining a permit and paying the required fees.1The Florida Legislature. Florida Code 553.79 – Permits; Applications; Issuance The Florida Building Code echoes that broadly: anyone intending to construct, enlarge, alter, repair, move, or demolish a building, or to install or replace any electrical, gas, mechanical, or plumbing system, must apply to the local building official before starting.2Nassau County. Florida Building Code Section 105 – Permits
In practical terms, that covers the projects homeowners actually ask about: replacing a roof, adding a room, upgrading an electrical panel, swapping out a water heater, building a deck, enclosing a patio, or installing a new HVAC system. Impact-resistant coverings such as hurricane shutters and impact windows are specifically included. If the work touches structure, waterproofing, fire safety, or any regulated system, assume a permit is required.
Work That’s Exempt
The code exempts minor work that doesn’t affect structural integrity, fire protection, or regulated systems, though the work itself still has to comply with the code. Cosmetic upgrades fall squarely in this category: painting, wallpapering, installing carpet or tile, and swapping out kitchen cabinets or countertops.
Specific low-risk mechanical and plumbing tasks are also exempt. On the mechanical side, that means portable heating and cooling units, replacement of minor equipment parts that don’t change the safety rating, and load management control devices. On the plumbing side, you can stop leaks in existing fixtures and make repairs that don’t involve replacing or rearranging pipes, valves, or fixtures.3Florida Building Commission. Permits, Plans, Inspections and Occupancy Classification Advanced Module Once you start replacing concealed pipes or rearranging drainage, that crosses into permit territory.
Fences, small storage sheds, and similar minor structures may also be exempt, but size thresholds and conditions vary by local jurisdiction. When in doubt, a quick call to the local building department is the fastest way to confirm. The penalty for guessing wrong is far more expensive than the phone call.
How to Apply
Applications are made on the Uniform Building Permit Application, a standardized form used across Florida counties and municipalities. It collects information about the property owner, the licensed contractor (if one is involved), and the scope of work, including materials and estimated project value.
Most building departments require supporting documents that vary by project type:
- A site plan or survey showing property boundaries and the location of the proposed improvement relative to setback lines and existing structures.
- Construction drawings. For structural work, plans signed and sealed by a licensed Florida engineer or architect are standard. Simple projects like re-roofing may only need a product approval sheet and basic specifications.
- Verification of the contractor’s state license. Florida’s Construction Industry Licensing Board, administered through the Department of Business and Professional Regulation, licenses individual contractors, and each construction business must be qualified by a properly licensed individual to operate in the state.4Florida Department of Business and Professional Regulation. Construction Industry – Business Information
- Proof of active liability insurance and workers’ compensation coverage for the contractor.
Most Florida building departments now accept applications through online portals where you can upload plans and pay fees electronically. Permit fees are set locally and typically scale with the project’s estimated value or square footage. A local enforcement agency cannot charge extra fees for providing proof of contractor licensure or workers’ compensation coverage at the time of application.5The Florida Legislature. Florida Code 553.80 – Enforcement
If You’re Pulling the Permit Yourself
Florida generally requires construction to be performed by licensed contractors, but a property owner can act as their own general contractor under the owner-builder exemption. The trade-off is that you take on full legal and financial responsibility for the project.6The Florida Legislature. Florida Code 489.103 – Contracting, Exemptions
To qualify, several conditions apply. The property must be a one-family or two-family residence, a farm outbuilding, or a commercial building costing no more than $75,000. It must be for your own occupancy or use, not built for sale or lease. You must personally provide direct, onsite supervision of all work not performed by licensed contractors. And you cannot hire unlicensed individuals to act as contractors or supervise work; any unlicensed workers must be your direct employees, which triggers obligations for federal income tax withholding, FICA, and workers’ compensation coverage.
The sale restriction catches people off guard. If you sell or lease a property within one year after completing owner-builder construction, Florida law presumes you built it for sale, which violates the exemption.6The Florida Legislature. Florida Code 489.103 – Contracting, Exemptions Before the building department will issue an owner-builder permit, you must sign a detailed disclosure statement acknowledging these risks, including the possibility that your homeowner’s insurance may not cover injuries to unlicensed workers on your property.
The Notice of Commencement
For any construction improvement with a direct contract price exceeding $2,500, the property owner must record a Notice of Commencement with the county clerk’s office before work begins.7Justia Law. Florida Code 713.13 – Notice of Commencement8The Florida Legislature. Florida Code 713.02 – Liens for Improvements to Real Property The $2,500 threshold comes from an exemption in Florida’s construction lien law; projects at or below that amount are exempt from the notice requirement.
The Notice of Commencement is a recorded public document that identifies the property, the owner, the general contractor, any construction lender, and the surety on any payment bond. It protects the owner against double-payment disputes by giving subcontractors and suppliers a clear record of who is responsible for the project. A certified copy of the notice, or a notarized statement that it was recorded, must be posted at the job site.
Timing matters. If work described in the notice doesn’t actually begin within 90 days of recording, the notice becomes void, and you’d need to record a new one before starting.7Justia Law. Florida Code 713.13 – Notice of Commencement Failing to record a Notice of Commencement altogether can delay inspections, complicate lien disputes, and create headaches at the closing table if you sell the property.
How Long Review Takes
Florida statute sets specific deadlines for local building departments to act on a completed permit application. These are binding unless the applicant waives them in writing.9The Florida Legislature. Florida Code 553.792 – Building Permit Application to Local Government
- 30 business days for residential permits (single-family homes, duplexes, accessory structures) and single-trade permits (electrical, plumbing, mechanical, roofing) for structures under 7,500 square feet.
- 60 business days for residential permits for structures 7,500 square feet or larger, nonresidential buildings under 25,000 square feet, multifamily projects of 50 units or fewer, and site-plan approvals that don’t require a public hearing.
- 12 business days for site-specific permits issued under a master building permit.
After submission, the local government has five business days to tell you in writing whether anything is missing. If the examiner requests revisions during the review, you have 10 business days to resubmit before the clock restarts. Once approved, the permit must be posted at the job site where inspectors and the public can see it.
The Private Provider Option
Florida law lets property owners and contractors hire a private provider, a licensed engineer or architect, to handle plan review and inspections instead of relying on the local building department. This route often moves faster.10The Florida Legislature. Florida Code 553.791 – Alternative Plans Review and Inspection
When a private provider submits a plan-review affidavit with the permit application, the local building official must issue the permit or provide a written list of specific code deficiencies within 20 business days, or just 5 business days for single-trade work on a single-family or two-family home. If the private provider is a licensed engineer or architect who seals the affidavit, that window drops to 10 business days. If the building official misses the deadline without responding, the permit is deemed approved as a matter of law and must be issued the next business day.10The Florida Legislature. Florida Code 553.791 – Alternative Plans Review and Inspection
To use a private provider, you must notify the local building official in writing at the time of the permit application, or at least two business days before the first scheduled inspection. You still pay local permit fees, and the building department retains authority to audit the private provider’s work.
Inspections, Completion, and Keeping the Permit Alive
The building department verifies compliance through inspections at specific construction milestones: after the foundation is poured, when framing is complete, after electrical and plumbing rough-ins are in place but before walls are closed, and again at completion. The exact sequence depends on the type of work. Scheduling is typically handled through an automated system or online portal using the permit number.
No new building can be occupied until the building official issues a Certificate of Occupancy confirming the construction complies with all applicable codes.11UpCodes. Florida Building Code, Building, 7th Edition, Chapter 1 – Scope and Administration For projects that don’t involve occupying a building, such as a system installation, a shell building, or a stand-alone utility connection, the building official issues a Certificate of Completion instead. A roof replacement, water heater swap, or electrical panel upgrade would receive a Certificate of Completion rather than a Certificate of Occupancy. In some situations, the building official can issue a temporary Certificate of Occupancy so you can move into a finished portion of the building while remaining work wraps up.
A Florida building permit doesn’t last forever. If the authorized work hasn’t started within 180 days of issuance, or if work is suspended or abandoned for 180 consecutive days at any point, the permit expires and becomes void. The clock resets each time you pass an inspection, so the practical rule is to get at least one inspection every 180 days to keep the permit alive. If you can’t start or continue work within that window, you can apply for a single 180-day extension, but the request must be made before the permit expires. Once a permit lapses, you’d need to apply and pay for a new one, and if the code has been updated in the interim, the new application may need to comply with more current standards.
What Happens If You Skip the Permit
Florida law makes it unlawful to perform regulated construction without a permit.12The Florida Legislature. Florida Code 553.79 – Permits, Applications, Issuance The specific penalties are set at the local level. Many building departments impose a multiplied permit fee, commonly double or more of the standard fee, when they discover work that started without authorization. Some jurisdictions also assess a separate penalty fee on top of the increased permit cost.
The immediate enforcement tool is a stop-work order. An inspector who discovers unpermitted construction can halt the project on the spot, and work cannot resume until the proper permits are obtained and any penalty fees are paid. Paying the penalties doesn’t waive the requirement to bring the work into full code compliance, which can mean tearing out finished work so an inspector can verify what’s behind the walls.
The longer-term consequences often hurt more. Unpermitted work can derail a home sale because buyers’ lenders and title companies flag open or missing permits, and you’re legally required to disclose known unpermitted work to prospective buyers before closing. For work that involves structural or life-safety systems, unpermitted construction can also create insurance coverage gaps if damage occurs and the insurer determines the work didn’t meet code.
Local governments can also increase inspection fees when repeated code violations occur. After an initial inspection and one reinspection for the same violation, subsequent reinspections can be charged at four times the standard inspection fee.5The Florida Legislature. Florida Code 553.80 – Enforcement The same multiplied-fee structure applies to plan reviews rejected three or more times for the same deficiency. These escalating costs add up fast.
