Florida Building Permits: What Every Homeowner & Buyer Needs to Know

Unpermitted work is one of the most common deal-killers and post-closing headaches in Florida real estate. Here is everything you need to know before you build, renovate, or buy.

What Requires a Permit in Florida

Florida law (Chapter 553, Florida Statutes — Building Construction Standards) sets the statewide floor. Local jurisdictions — cities, counties, and special building departments — can and often do impose stricter requirements. When in doubt, call your local building department before any project starts.

The following work almost always requires a permit in Florida:

• Structural changes: Adding or removing load-bearing walls, room additions, garage conversions, enclosing a porch or lanai, second-story additions
• Electrical: New circuits, panel upgrades or replacements, adding outlets or fixtures (beyond simple swap), generators, EV chargers
• Plumbing: New supply or drain lines, water heater replacement, moving fixtures, re-piping, irrigation systems with backflow prevention
• HVAC: New system installation, replacing an air handler or condensing unit, adding ductwork, mini-split installation
• Roofing: Full roof replacement or recovering; re-roofing more than 25% of a roof in any 12-month period in many counties
• Pools & spas: New construction, significant modifications; pool safety barriers are separately required by FL law
• Solar: Photovoltaic panel installation on the roof or ground-mounted systems connected to the home
• Fences: Fences over 6 feet in height; some municipalities require permits for any fence regardless of height
• Decks & patios: Attached decks, screened enclosures, pergolas attached to the structure
• Windows & doors: Any structural opening change; Florida impact-resistant window replacement generally requires a permit to verify code compliance
• Sheds & accessory structures: Permanent structures over a certain square footage (often 120–200 sq ft, varies by jurisdiction)
• Demolition: Full or partial demolition of a structure

What Does NOT Require a Permit

Purely cosmetic and non-structural work is typically exempt from permitting under the Florida Building Code. Common permit-exempt projects include:

• Interior and exterior painting
• Flooring replacement (carpet, tile, hardwood, LVP) that does not alter the subfloor structure
• Cabinet replacement in the same location without moving plumbing or electrical
• Countertop replacement
• Minor drywall repairs (patching holes, not structural modifications)
• Fixture swaps: replacing a faucet, toilet, or light fixture in the same location on existing wiring or plumbing
• Appliance replacement (same location, no new circuits)
• Landscaping and sod work
• Fences under the local height threshold (often 6 ft) — verify locally
• Prefabricated sheds under the local square footage threshold (verify locally)

The Florida Building Code (FBC): Statewide Minimum

Florida operates under a single statewide building code — the Florida Building Code (FBC) — adopted under Chapter 553, F.S. The current edition is updated on a rolling basis and sets the minimum standard across all 67 counties.

Key things to know about the FBC:

• Local governments cannot lower the FBC's standards, but they can adopt more stringent local amendments.
• Miami-Dade and Broward counties have historically had stricter hurricane and wind-load requirements that exceed the statewide minimum.
• The FBC includes specialized volumes: Residential, Building, Existing Building, Energy Conservation, Plumbing, Mechanical, Fuel Gas, and Accessibility.
• Florida's High-Velocity Hurricane Zone (HVHZ) — covering Miami-Dade and Broward — has the most rigorous wind-resistance requirements in the country.

Quick Reference: Permit Required vs. Not Required

The Permit Pull Process in Florida

Getting a permit in Florida follows a standard sequence, though timeline and fees vary by jurisdiction and project complexity.

1. Application submission: The permit application is filed with the local building department — either online through the jurisdiction's portal or in person. Most larger counties now offer online permitting (e.g., Miami-Dade's iBuild, Orange County's Accela portal).
2. Plan review: For simple projects, an automated or over-the-counter review may be completed same-day. For complex work (structural additions, new construction), plans go through a multi-department review — structural, zoning, fire, electrical — that can take weeks.
3. Permit issuance: Once approved and fees paid, the permit is issued. The permit card (physical or digital) must be posted at the job site.
4. Inspections: Work is inspected at defined stages — rough-in (before walls close), framing, insulation, final. The inspector approves each stage before work continues.
5. Certificate of Completion / Occupancy: After the final inspection passes, a Certificate of Completion (for alterations) or Certificate of Occupancy (for new structures or additions) is issued. This closes the permit.

Who Pulls the Permit: Contractor vs. Owner-Builder

In Florida, a licensed contractor is generally required to pull the permit for work they perform. This is not just a formality — it ties the contractor's license and insurance to the project.

Owner-Builder Permits

Florida does allow homeowners to pull their own permits as "owner-builders" under certain conditions:

• The homeowner must personally reside in, or intend to reside in, the structure being built or improved.
• Owner-builder permits cannot be used for work the homeowner is doing for sale or lease within one year of completion (Florida presumes intent to sell if sold within 1 year).
• The homeowner assumes full responsibility for code compliance and must pass all required inspections.
• Owner-builders may hire unlicensed workers to assist, but cannot subcontract work that requires a licensed subcontractor (e.g., electrical, plumbing, HVAC) to an unlicensed person.

Typical Permit Costs in Florida

Permit fees in Florida are set by each local jurisdiction and vary widely. Here are rough ranges for common project types:

For large renovation projects, many Florida counties charge permit fees as a percentage of the project's declared construction value — typically 1%–2% of total project cost.

Permit Timelines: What to Expect

Processing time depends heavily on project complexity and your local building department's workload:

• Simple mechanical permits (HVAC swap, water heater): Often issued same-day or next-day, sometimes automatically through online portals.
• Moderate projects (roof, windows, minor electrical): 1–5 business days for plan review in most jurisdictions.
• Complex projects (additions, pool, new construction): Plan review cycles of 4–12 weeks are common in busy South Florida counties. Multiple review rounds may add time.
• Post-hurricane surge: After major storms, permit offices can be backlogged for months. Factor this into renovation timelines.

How to Check Permits on a Home You Are Buying

Before closing on any Florida property, a thorough permit history check is essential. Here are the primary ways to do it:

1. County Building Department Records

Every Florida county maintains permit records. Most offer online searches by address. Search for the property address and look for:

• All permits ever pulled on the address
• Whether each permit received a final inspection and was closed
• Any open, expired, or failed permits
• The scope of work described in each permit

2. County Property Appraiser Portal

The county property appraiser's record shows the official square footage, year built, and number of bedrooms/bathrooms. If the home's physical layout does not match the appraiser's record, that discrepancy often signals an unpermitted addition or conversion.

3. Ask for Permit History at Inspection

A good home inspector will flag visible signs of unpermitted work — non-standard wiring, mismatched materials, unusual framing — but they are not code inspectors. Always pair a home inspection with a permit search.

4. Request Disclosure from Seller

Florida's seller disclosure law (F.S. 689.261) requires sellers to disclose known defects and material issues. Unpermitted work is a material defect that must be disclosed if the seller is aware of it.

The Risks of Buying a Home With Unpermitted Work

This is the section to read carefully if you are a buyer. Unpermitted work in Florida carries serious, transferable consequences:

Insurance Problems

Homeowners insurance carriers can deny a claim — or cancel your policy — if they discover the damage involves or stems from unpermitted work. A roof replacement done without a permit that causes a water intrusion claim is a prime example. In a state where windstorm and flood coverage are already difficult to obtain, this risk is amplified.

Financing Problems

Lenders underwriting conventional, FHA, or VA loans may require unpermitted additions or conversions to be properly permitted and inspected before closing. If significant unpermitted square footage inflated the appraised value, the loan may not close at all.

Retroactive Permitting or Demolition

The local building department can require you — as the new owner — to either pull a retroactive permit and bring the work up to current code, or demolish the unpermitted structure. Bringing old work up to current code (especially post-2004 updated Florida Building Code) can cost significantly more than the original project.

Liability Transfers to You

Once you close, you own the problem. Even if the previous owner did the unpermitted work decades ago, you are now the responsible party. The seller's misconduct does not shield you from the enforcement action.

Resale Complications

When you eventually sell, you will be required to disclose the unpermitted work to your buyer. This depresses offers, kills deals, and can create legal exposure if undisclosed.

How to Legalize Unpermitted Work Before Closing

When unpermitted work is discovered during due diligence, you have several options. None are painless, but all are better than closing blind.

Option 1: Seller Pulls the Retroactive Permit

The seller applies for a permit after the fact (sometimes called an "after-the-fact permit" or AFA permit). An inspector comes out, reviews the work, and either approves it or requires corrections. The seller pays all fees and remediation costs. This is the cleanest outcome for the buyer.

Option 2: Seller Credits Buyer at Closing

The seller provides a dollar credit sufficient to cover the cost of retroactive permitting and any required remediation. The buyer handles it post-closing. This is riskier — the actual cost can exceed the credit — but common when timeline is tight.

Option 3: Price Reduction

The buyer negotiates a lower purchase price reflecting the risk and estimated cost of resolution. This is often paired with Option 2 as a hybrid.

Option 4: Walk Away

Under a standard Florida contract with inspection contingency, a buyer can walk away if unpermitted work represents a material defect that the seller refuses to remedy. Know your contract terms and deadlines.

Florida Chapter 553: Building Construction Standards

The legal backbone for Florida's building permit system is Chapter 553, Florida Statutes (Building Construction Standards). Key provisions include:

• 553.37: Establishes the requirement for building permits statewide and sets the framework for local enforcement.
• 553.38: Authorizes local jurisdictions to adopt the FBC and establish their own building departments.
• 553.48: The owner-builder provision — defines when homeowners can act as their own contractor.
• 553.84: Creates a private right of action for buyers injured by violations of the FBC, including failures to obtain required permits. This is the legal hook that allows a buyer to sue a seller who knowingly concealed unpermitted work.
• 553.992: Addresses accessibility requirements for public accommodations — relevant for commercial but sets context for residential modifications.
