How to Get a Municipality After-the-Fact Permit in Florida

Key Takeaways

• Confirm which municipality or county has jurisdiction over your property before applying, as mailing addresses can be misleading; use the property appraiser website and call the building department directly to verify.

• After-the-fact permits are not automatic approvals; the building department reviews finished work against applicable building, zoning, and local codes just like new construction, and may require corrections.

• Each Florida jurisdiction sets its own ATF fees, documentation requirements, and processes; some charge double the standard permit fee while others do not, so verify current costs with your local authority before budgeting.

• Do not expose concealed work behind walls or ceilings until consulting the building department; a sealed engineer letter is often the most cost-effective way to document hidden work and satisfy compliance verification.

• Unpermitted work resurfaces at critical moments like home sales, refinancing, or insurance claims, potentially causing delays, fines, or liens; resolving it early through the ATF process prevents costly complications.

• Respond quickly and completely to plan review comments during the application process; inspections must pass and the permit must be officially closed in the municipality's system to avoid future title and financing issues.

So, you just discovered that a deck, a re-roof, a pool cage, or a kitchen remodel was built without a permit. Maybe you bought the house that way. Maybe a contractor promised to pull the permit and never did. Take a breath. This happens to Florida property owners all the time, and it is very fixable.

The fix is called an after-the-fact permit, or ATF. A municipality after the fact permit in Florida is simply a building permit application for work that was already built, or already started, without the required approval. Your city or county building department reviews it, decides what proof it needs, and, if everything checks out, finally approves and closes it out.

In this guide, we will walk you through the process step by step, from figuring out which municipality actually controls your property to documents, inspections, costs, and what happens when work is hidden behind a wall. Whether you are a homeowner, a general contractor, a solar company, or a real estate professional, you will leave knowing exactly what to do next.

What Is an After-the-Fact Permit in Florida?

Florida law is clear on the starting point: under Florida Statutes §553.79, it is unlawful to construct, alter, repair, or demolish a building without first obtaining a permit from the appropriate enforcing agency. When that step gets skipped, the after-the-fact route is how owners get back into compliance.

Here is the part that surprises many people. An ATF permit is not a rubber stamp. It is not a waiver of code requirements, and it does not guarantee approval. The local building department reviews the finished work against the applicable building, zoning, and other local rules, just as it would for any other project.

The state sets the rule that permits are required. The municipality or county sets how the ATF process actually works. That includes fees, forms, documentation, inspections, and enforcement. For a deeper primer, see our explainer on what after-the-fact permitting is in Florida.

Step 1: Confirm Which Municipality or County Has Jurisdiction

Before you do anything else, find out who actually issues permits for your address. This sounds simple, but it trips up a lot of owners, especially near city lines.

A city generally handles permits within its municipal limits. A county typically serves unincorporated areas and, in some cases, particular municipalities under an agreement. A mailing address that says "Tampa" or "Orlando" does not always mean the city is your permitting authority. Confirm with the local building department before you apply.

1. Pull your property address and parcel number from your deed or the property appraiser website.
2. Check whether the parcel sits inside city limits or in unincorporated county.
3. Call the building department and ask whether they accept after-the-fact applications for your type of work.
4. Ask for their written ATF checklist, fee schedule, and submittal method.

Step 2: Check for Open Permits and Violations

Next, find out what is already on record. Sometimes the "unpermitted" work turns out to be an expired or open permit that was never closed, which is a different fix than a true ATF application. Other times, a code enforcement case already exists.

• Search the municipality's permit portal for your address.
• Look for expired, open, or inactive permits tied to the same scope of work.
• Check for any notice of violation, stop work order, or code case.
• Ask the building department whether a hold is affecting your property.

Our open permit search tool is a good place to start. If you find an expired permit rather than no permit at all, take a look at after-the-fact and expired permit services to see how those cases differ.

Step 3: Gather the Documentation the Municipality Requires

This is where most of the real work happens. Every jurisdiction has its own list, but you should expect to document the work thoroughly. Applications commonly ask for some combination of the following:

Some jurisdictions also remind applicants that separate deed restrictions, HOA rules, or permits from other government agencies may apply. For example, the City of Marathon's ATF application cautions that other approvals may still be needed. Always ask what else is required beyond the building permit itself.

Step 4: Handle Concealed Work the Right Way

What if the work is hidden behind drywall, under a floor, or above a ceiling? This is one of the most common worries, and it is a fair one.

If work is concealed, the building official may require it to be exposed, or supported by an acceptable evaluation, so compliance can be verified. St. Lucie County, for instance, notes that concealed work may require a third-party engineering analysis. Requirements depend on the type of work and the local authority.

Here is our friendly advice: do not open walls or hire an evaluator until you have talked to the building department. Opening things up prematurely can waste money, and an engineer's report that does not match what the jurisdiction wants will not help you.

A sealed engineer letter is often the cleanest way to document what cannot be seen. If you are curious how this works, our guide on using an engineer letter to save your permit walks through it.

Step 5: Submit the Application and Expect Review Comments

Once your package is ready, you submit it through the municipality's preferred channel, whether that is an online portal, email, or in person. Then comes plan review.

A quick note on timing. Florida Statutes §553.792 sets review deadlines for certain complete and sufficient building permit applications, including 30 business days for specified permits on structures under 7,500 square feet and 60 business days for several other listed categories. However, that statute does not create a separate statewide deadline specifically for ATF approvals. The best move is to ask the local jurisdiction how long it typically takes to process these applications.

Do not be discouraged by review comments. They are normal. Reviewers may ask for added engineering, corrected drawings, or clarification of product approvals. Responding quickly and completely keeps your file moving. Our team handles this daily through plan review coordination and revisions and resubmittals.

Step 6: Pass Inspections and Close Out the Permit

After approval and issuance, the work still has to be inspected. Depending on the project, inspectors may verify framing, electrical, plumbing, mechanical, roofing, or final conditions. If any portion fails, you correct it and schedule a re-inspection.

1. Pay the permit fees once the municipality issues the permit.
2. Schedule the required inspections.
3. Correct anything the inspector flags.
4. Pass final inspection.
5. Confirm the permit is closed in the municipality's system.

That last step matters more than most people realize. A permit that stays open will show up again at refinancing or closing. Some projects use a licensed private provider for faster scheduling; learn more about private provider inspections and how they compare in this article on private provider vs. building department in Florida.

What Does a Municipality After-the-Fact Permit Cost?

Here is the honest answer: it depends on where you live. The available sources do not establish a single statewide ATF fee, penalty amount, or processing time. Each jurisdiction sets its own schedule, and you should verify current fees with the authority having jurisdiction.

As one example, St. Lucie County says its after-the-fact permit fee is double the regular fee. That is a county-specific practice, not a statewide rule. Other municipalities may charge differently, so never assume the doubled-fee model applies to you.

What Happens If You Do Nothing?

It is tempting to hope the problem quietly disappears. Unfortunately, unpermitted work tends to resurface at the worst moments, such as a home sale, an insurance claim, or a neighbor's complaint.

Enforcement is handled locally, and it varies. St. Lucie County, for example, warns that unresolved violations may result in a notice of violation, fines, or a lien. The exact process and consequences depend on the local ordinance and your circumstances.

• Home sales: Buyers, lenders, and title companies may flag open or missing permits and delay closing.
• Insurance: Unpermitted work can complicate claims.
• Code enforcement: A complaint can trigger a notice of violation and fines.
• Safety: Work no one inspected may hide real hazards.

Tips for Each Type of Property Owner

Homeowners and Residential Property Owners

Start with the building department call, then gather photos and any receipts or contracts. If you bought the home with unpermitted work, you are not alone, and the same ATF process applies. Our homeowner services are designed for exactly this.

General Contractors and Design Trades

If a subcontractor skipped a permit on your job, move fast. Document the scope, get your drawings and engineering aligned, and coordinate with the municipality before a stop work order lands. See how we support general contractors.

Solar Companies

Solar installs need code-compliant structural and electrical documentation. If an array went in without a permit, expect the reviewer to want roof-structure verification and electrical details. Visit our page for solar contractors.

Realtors, Investors, and Buyers

Unpermitted work discovered during due diligence does not have to kill a deal. Researching permit history early gives everyone time to legalize. Explore our realtor and closing support.

Can a Permitting Service Apply on Your Behalf?

Yes, in many cases. A permitting service can identify the correct authority, assemble the application and technical documentation, coordinate inspections, and track the file. What it cannot do is approve the permit. Only the local building department can decide whether the work complies.
