How to Fix Work Built Without a Permit in Florida

Key Takeaways

• Florida Statute §553.79 requires permits for construction, and unpermitted work can be fixed through after-the-fact permits, which are doable but may not be instant or cheap.

• Unpermitted work can derail home sales, trigger insurance claim denials, result in fines and liens, and block future projects, making proactive resolution critical before closing or enforcement action.

• Common unpermitted items include room additions, roof replacements, electrical/plumbing/HVAC changes, pools, remodels, solar installations, and window upgrades—often inherited from previous owners or contractors.

• The after-the-fact permit process requires identifying the correct jurisdiction, gathering documentation, submitting sealed plans or engineer letters, passing inspections, and closing the permit to legalize work.

• Costs vary by jurisdiction but typically include permit fees, after-the-fact penalties (sometimes double the standard fee), engineering or sealed drawings, and corrections; St. Lucie County example shows importance of acting early.

• Avoid hiding additional work, assuming contractors handled permits, filing in wrong jurisdiction, submitting incomplete applications, and ignoring violation notices—each mistake delays resolution and increases costs.

Here's a moment plenty of Florida property owners know well. You're buying a home, finishing a remodel, or just pulling out old paperwork, and someone says the words nobody wants to hear: "That doesn't appear to have been permitted." Your stomach drops. Your mind jumps to fines, tear-outs, and ruined closing dates.

Take a breath. If something was built without a permit in Florida, you are far from alone, and in most cases there is a clear path to make it right. Florida Statute §553.79 generally requires a permit before you construct, alter, repair, or demolish a building, and the fix for work that skipped that step is typically an after-the-fact permit. It isn't always cheap or instant, but it is very doable.

In this friendly, step-by-step guide, we'll walk through exactly what to do, what to expect from inspectors, what it might cost, and how to avoid common missteps. Whether you're a homeowner, a general contractor, a solar company, or a real estate pro, you'll leave knowing your next move. We'll also show where 1 Contractor Solutions can take the heavy lifting off your plate.

What "Built Without a Permit" Actually Means in Florida

In simple terms, work is unpermitted when it required a permit and the owner or contractor never got one, or the permit expired or was never closed out. Florida law makes it unlawful to build or alter a structure without a permit from the proper state or local enforcing agency, unless an exemption applies.

That covers a lot more than people expect. Here are some of the most common examples we see across the state:

• Room additions, enclosed patios, and garage conversions
• Roof replacements and structural roof repairs
• Electrical, plumbing, and HVAC changes
• Pools, pool cages, and retaining walls
• Kitchen and bath remodels that moved walls or utilities
• Windows, doors, and impact upgrades
• Solar panel installations

It's also worth knowing that unpermitted work isn't always the current owner's doing. Many owners inherit the problem from a previous seller or a contractor who promised to "handle the permit" and never did. If that sounds familiar, our guide on what to do if a prior owner skipped permits in Florida is a great companion read.

Why Fixing It Matters

Let's be honest: it's tempting to leave sleeping dogs lie. But unresolved unpermitted work tends to wake up at the worst possible moment.

The Real-World Risks

• Selling and closing: Buyers, lenders, and title companies increasingly catch unpermitted work, and it can stall or kill a deal.
• Insurance: Claims tied to unpermitted work may be questioned or denied.
• Safety: Permits and inspections exist so wiring, framing, and structural connections are verified by someone other than the person who built them.
• Enforcement: Unresolved violations can lead to notices of violation, fines, and even liens on the property.
• Future projects: You may not be able to permit new work on a property with open violations.

The good news? Solving it proactively is almost always easier, cheaper, and less stressful than being forced to react after a code officer knocks on your door. For a deeper look at fines and consequences, see our breakdown of the penalty for building without a permit in Florida.

Step-by-Step: How to Fix Unpermitted Work in Florida

Every county and city runs things a little differently, but the overall process follows a familiar pattern. Here's the roadmap most owners follow.

1. Pause any further work. Don't cover, paint, or conceal anything else until you know what the building department needs to see.
2. Confirm which jurisdiction controls your property. This is trickier than it sounds near city lines. Our building department lookup tool can help point you in the right direction.
3. Check for open or expired permits. Sometimes a permit exists but was never finaled. Try the open permit search before assuming you're starting from scratch.
4. Gather what you have. Collect photos, receipts, contractor information, surveys, and any old plans.
5. Contact the building department. Ask for the after-the-fact permit checklist and current fee schedule for your exact address.
6. Prepare plans and documentation. Depending on the work, you may need as-built drawings, an engineer letter, or sealed structural or MEP documentation.
7. Submit the application and pay fees. Expect plan review, comments, and possibly a revision cycle.
8. Pass inspections. Inspectors verify the work meets code, and may ask you to correct deficiencies.
9. Close out the permit. Final approval is what actually legalizes the work on paper.

It sounds like a lot when it's laid out in a list, but each step is manageable, especially with a good partner. And remember: filing an application does not itself legalize anything. The work has to be reviewed, inspected, and approved before the permit can be closed.

What an After-the-Fact Permit Really Is

An after-the-fact permit (sometimes called a retroactive or "as-built" permit) is simply a permit application for work that's already been done. The building department treats it much like a normal permit, except the inspector is verifying finished work instead of work in progress.

If you want a full walkthrough of this specific process, our guide to how to get an after-the-fact permit in Florida goes deeper, and our after-the-fact and expired permit service page explains how we handle these files.

Documents You May Need

Requirements vary by jurisdiction. For example, one Treasure Coast procedure document notes a Notice of Commencement must be submitted before the first inspection when job value exceeds $2,500. Always confirm with your local office.

Will They Make Me Open Up Walls?

This is the question we hear most, and the honest answer is: sometimes. If framing, wiring, plumbing, or other components are concealed, an inspector may need to verify them. Depending on the work and the jurisdiction, that can mean exposing finished areas.

But there's good news here too. In many cases, a Florida-licensed engineer can inspect and certify concealed or structural components, which can reduce how much needs to be opened. Our engineer letters and as-built drawings services exist for exactly this situation, and because our drafting and engineering are done in house, questions from reviewers get answered quickly.

What Will It Cost?

There's no single statewide price, because fees are set locally. What we can tell you is the general pattern.

As one local example, St. Lucie County states that its after-the-fact permit fee is double the standard fee, and warns that unresolved violations may result in fines and a lien. That is a county-specific rule, not a statewide rate, but it shows why acting early matters. For a closer look at numbers, check out our article on after-the-fact permit costs in Florida.

Common Mistakes to Avoid

After handling thousands of permits, we've seen the same stumbling blocks over and over. Dodge these, and you're already ahead of the game:

• Hiding or covering more work. It makes inspection harder and more expensive.
• Assuming the contractor "took care of it." Always verify the permit exists and was finaled.
• Guessing at the jurisdiction. Filing in the wrong place wastes weeks.
• Submitting incomplete packages. Missing drawings or seals trigger rejection cycles.
• Ignoring a violation notice. Deadlines in these notices are real, and fines can accumulate.
• Waiting until a closing is days away. Review timelines don't bend for contract dates.

Tips for Different Audiences

For Homeowners and Residential Property Owners

Start by finding out exactly what was done and when. Old listing photos, prior inspection reports, and neighbor recollections can help establish a timeline. Then reach out to the building department before touching anything else. If this feels overwhelming, our homeowner services are designed to walk you through it without the jargon.

For Real Estate Professionals and Investors

Time is your biggest enemy. If a buyer, lender, or title company flags unpermitted work, start the permitting research immediately rather than hoping it goes away. Early clarity lets you negotiate honestly, price repairs accurately, and keep the deal alive. Our realtor and closing support team works on exactly these situations.

For General Contractors and Design Trades

If you've inherited a job where a prior trade skipped permits, resolving it quickly protects your license and your schedule. Having a team that can draft, engineer, file, and respond to reviewer comments in one place keeps you out of the permit queue weeds. Learn more on our general contractor page.

For Solar Companies

Unpermitted or improperly documented installs can hold up inspections and utility interconnection. Code-compliant structural and electrical documentation matters from day one, and fixing past gaps quickly protects your reputation. Our solar contractor services are built around fast, accurate filings.

When It's Time to Call in Help

You can absolutely start the process yourself by calling your local building department. But many owners reach a point where the paperwork, drawings, and reviewer comments become a part-time job. That's the moment a dedicated permitting team earns its keep.

At 1 Contractor Solutions, we act as Florida's outsourced permitting department. We figure out which jurisdiction actually controls your property, prepare or review the plans, file the application, track it, answer reviewer comments, and carry it through approval and closeout. Our in-house engineering team seals the work, so when a reviewer flags something, we fix it directly rather than waiting on an outside consultant. We serve all 67 Florida counties and have handled more than 5,000 permits and projects.

If the situation is urgent, such as a stop work order, denial, or a closing hanging by a thread, our urgent permit rescue team is built for exactly that. And if you're curious how others have fared, you can read what customers say about 1 Contractor Solutions on Google through our Google Business Profile.

How Long Does It Take?

Timelines depend heavily on the jurisdiction, the complexity of the work, and how complete your submission is. A simple, well-documented case can move reasonably quickly, while larger structural or multi-agency reviews take longer. Zoning, setbacks, easements, utilities, fire safety, or environmental health reviews may add steps.

One way some owners shorten the wait is by using a licensed private provider for plan review and inspections, which can reduce dependence on the county queue where it's permitted. Learn how it works on our private provider plan review and inspections page.

A Quick Checklist Before You Pick Up the Phone

• Property address and parcel information
• Photos of the completed work, including any visible electrical or plumbing
• Names and license numbers of any contractors involved
• Receipts, invoices, or contracts
• Any prior permits, plans, or surveys
• A rough timeline of when the work was done

Having these items ready makes your first conversation with the building department, or with us, far more productive.

Wrapping Up: You Can Fix This

Discovering that something was built without a permit in Florida feels heavy, but it's one of the most common and most fixable problems in construction and real estate. Stop further concealing work, identify the right jurisdiction, gather your documents, and move through an after-the-fact permit with proper plans, inspections, and closeout. Each step is manageable, especially with the right team beside you.
