Florida Building Code Florida Building Code.

Florida Building Code is the Florida state building code — every residential project at scale needs a Florida Building Code permit, and the contractor (not the homeowner) pulls it under their Certified General Contractor (CGC). Here's what triggers a permit, who files what, and how inspections actually run.

What Florida Building Code Is

Florida Building Code is the Florida state building code, codified at 780 Code of Florida Regulations. It is enforced statewide, but individual municipalities can adopt additional requirements (most notably the Florida Energy Code in 14 Florida cities). Florida Building Code is updated periodically — the current edition incorporates the International Building Code 2021 with Florida amendments.

For residential homeowners, the practical reality is: any work that adds, alters, or repairs structural, mechanical, electrical, plumbing, or gas systems triggers a Florida Building Code permit. The permit must be pulled by a Florida-licensed Certified General Contractor (CGC) — homeowners can technically pull permits on owner-occupied properties under specific exemptions, but doing so transfers liability to the homeowner and disqualifies most insurance and warranty coverage.

What Triggers a Florida Building Code Permit

Structural alterations: Wall removal, addition, deck, foundation work, basement finish (when adding habitable space), garage conversion, dormer, second-story addition.
Mechanical (HVAC): New HVAC system install, ductwork addition, water heater replacement (gas), boiler replacement, heat pump install. Like-for-like equipment swaps in the same location often qualify for a streamlined permit.
Electrical: Panel upgrade, new circuit installation, generator install, EV charger install, knob-and-tube replacement. Also covered under Florida Fire Prevention Code (Florida electrical code, supplements Florida Building Code).
Plumbing & gas: Repipe, new fixture installation that requires routing, water heater (electric), gas line work. Covered under Florida Energy Code (Florida plumbing/gas code, supplements Florida Building Code).
Roofing: Full roof replacement and structural roof modification. Like-for-like shingle replacement on existing roof deck often qualifies for a streamlined permit.
Windows & doors: Replacement windows in existing openings often do not require a permit. Adding an opening (cutting a new window) does require a permit.

Who Pulls the Permit

The contractor pulls the permit under their Florida contractor license (CGC) or applicable trade license. The homeowner signs no permit applications and is not on the building department records as the responsible party.

Florida allows owner-occupied homeowners to pull permits on their primary residence under specific exemptions, but doing so:

Transfers all liability for code compliance to the homeowner
Disqualifies most homeowner insurance coverage on the work
Voids most manufacturer warranties on installation defects
Triggers enhanced inspection scrutiny (assumed unlicensed work)
Can complicate eventual home sale (title issues if work was done without proper permits)

In practice: let the contractor pull the permit. If a contractor asks you to pull the permit, that is a sign they are unlicensed for the scope.

Inspection Sequence

Permit issuance. Filed by IWD Miami with municipal building department. Typically 3–10 business days for residential permits.
Rough inspection. Before drywall closes up. Inspector checks framing, electrical rough, plumbing rough, mechanical rough. All trades must pass before closing.
Insulation inspection (when applicable). Before vapor barrier install.
Final inspection. All trades visible and operational. Inspector tests outlets, runs HVAC system, verifies code compliance, signs off.
Certificate of Occupancy (when applicable for major scope). Issued after final inspection passes.

IWD Miami coordinates every inspection with the municipal inspector — homeowner does not need to be present (we hold the keys to the work area during the project).

Homeowner Rights Under Florida Building Code

Right to demand contractor produce the active CGC number on every permit application.
Right to see the permit posted at the work site (required by law).
Right to be present at any inspection.
Right to re-inspection at no additional charge if the work fails inspection due to contractor error.
Right to file a complaint with the Florida Department of Public Safety (DPS) if a contractor falsifies permit information.
Right to refuse final payment until certificate of occupancy is issued (where applicable).

780 Resource FAQs

Florida 780 Resource Questions Answered.

Do small repairs require a Florida Building Code permit?

Generally no. Replacing a faucet, installing a ceiling fan in an existing electrical box, painting interior, refinishing floors — none of these trigger a permit. Permits are required when work alters structural, mechanical, electrical, plumbing, or gas systems.

How long does a Florida permit take to issue?

Standard residential permits typically issue in 3–10 business days. Larger projects (additions, ADUs, structural work) can take 2–6 weeks pending plan review. IWD Miami files all permits same-day after contract signing.

What does a Florida permit cost?

Permit fees are set by each municipality and depend on project value. Typical residential mechanical permit: $50–$200. Electrical permit: $50–$200. Plumbing permit: $50–$200. Building permit (structural): $200–$2,000+ depending on scope.

Can I do my own work on my Florida home?

For owner-occupied primary residences, yes — under the homeowner exemption. But this transfers liability to you, voids most insurance/warranty coverage, and creates title complications when you sell. We do not recommend it for any work involving electrical, plumbing, gas, or structural systems.

What happens if a contractor works without a permit?

Multiple bad outcomes: failed insurance claims if anything goes wrong, voided manufacturer warranties, fines from the Florida Department of Public Safety, mandatory rework to bring up to code, and title complications when you sell the home. Always verify the permit was pulled before the work starts.

Does Florida Building Code apply to commercial work?

Yes. Florida Building Code covers both residential and commercial. Commercial scope has additional requirements (ADA compliance, fire suppression, hood ventilation, occupancy classifications). IWD Miami handles residential scope and a subset of light-commercial scope.

Can I see the Florida Building Code text online?

Yes — the full code is published on the Florida state government website (myfloridalicense.com). The current edition is referenced as Florida Building Code with year-of-amendment in the chapter heading.

What is the difference between Florida Building Code, Florida Fire Prevention Code, and Florida Energy Code?

Florida Building Code is the state building code (structural, mechanical at high level). Florida Fire Prevention Code is the Florida electrical code (deeper electrical specifics). Florida Energy Code is the Florida plumbing and gas code (plumbing and gas specifics). All three apply concurrently — your project may need permits under more than one.
