How to Pick Who to Hire to Legalize Unpermitted Work in FL

Key Takeaways

• Start with the local building department, not a private consultant, since only the building official can approve an after-the-fact permit and set the required corrections or inspections.

• Legalizing unpermitted work is a team effort: a building department decides, a Florida-licensed contractor handles corrections, an architect or engineer seals as-built documents, and a permitting consultant manages the process.

• Verify every license on the state's official lookup before signing, and confirm the specific discipline, since a local license alone may not satisfy state licensure requirements in Florida.

• Ask the department in writing for its after-the-fact checklist, and get a written scope and fee proposal that states who prepares and signs plans and who manages corrections and final approval.

• An after-the-fact permit does not erase the original violation or guarantee the work can stay; you may owe fees or penalties, must correct deficiencies, or may need to remove noncompliant work.

• Closeout, meaning the final inspection and sign-off, is what actually resolves the issue, so plan for every reviewer comment and inspection through completion rather than just submitting the application.

So you just found out that the deck, the garage conversion, or the kitchen remodel at your Florida property never got a permit. Take a breath. You are far from alone, and it is very fixable. The real question is who should I hire to legalize unpermitted work in Florida, because the answer is rarely just one person.

Here is the friendly truth: legalizing unpermitted work is a team effort. The local building department decides what is acceptable, a licensed contractor handles physical corrections, a Florida-licensed architect or engineer documents what was built, and a permitting professional keeps the whole process moving. Hire the wrong mix and you can lose weeks or even months.

In this guide, we will walk through each role, show you how to match the right professionals to your situation, and share a simple step-by-step plan. Whether you are a homeowner, a general contractor, a solar company, or a real estate professional, you will leave knowing exactly who to call first in 2026.

Start With the Building Department, Not a Hire

Before you pay anyone, find out who actually has authority over your property. In Florida, Florida Statutes section 553.79 generally requires a permit from the appropriate enforcing agency before covered construction, alteration, repair, or demolition begins. The local building department, not a private consultant, decides whether an after-the-fact permit is approved and what inspections or corrections are required.

Jurisdiction can be surprisingly tricky near city lines. A property with a city mailing address may actually fall under the county. Our building department lookup tool can help you confirm who really controls your address.

Once you know the department, ask these questions:

• What documents are required for an after-the-fact permit on this property?
• Do you require sealed as-built plans from an architect or engineer?
• Will inspectors need concealed work exposed or tested?
• What fees or penalties apply to work done without a permit?
• Is a licensed contractor required to pull the permit?

Get the answers in writing if you can. They will shape every hiring decision that follows.

The Core Professionals You May Need

Most legalization projects draw on four types of help. Which ones you need depends on the scope of the work, whether it is concealed, and what your local jurisdiction demands.

The Licensed Contractor

A Florida-licensed general or building contractor manages construction corrections and can pull the permit. Florida law generally requires an active state certificate or registration for contracting activities that need licensure, and a local license alone is not enough where state licensure applies (see Florida Statutes chapter 489). Always verify the license and the specific discipline before you sign anything.

If you are weighing whether you can do it yourself, our guide on who can pull a permit in Florida explains the options, including owner-builder permits.

The Architect or Engineer

Some jurisdictions require a licensed professional to inspect and certify the as-built work. Palm Beach is one local example: its legalization guidance calls for an as-built and legalization certificate prepared, signed, and sealed by a Florida-licensed engineer or registered architect in covered cases. That is a local requirement, not a statewide rule, so always confirm with your own department.

When structural elements are involved, such as roof framing, additions, or load paths, a sealed engineer letter can be the difference between approval and a denial. Learn more about engineer letters and structural engineering support.

The Permitting Consultant

A permit expediter or consultant is your project manager. They identify the authority having jurisdiction, assemble the application, coordinate the licensed professionals, and chase reviews. What they cannot do is approve the work, replace a contractor's license, or stand in for an engineer's seal. If someone promises they can "just get it approved," be cautious.

This is the role 1 Contractor Solutions plays. We are Florida's outsourced permitting department, handling permit facilitation and filing across all 67 counties, with in-house drafting and sealed engineering so reviewer comments get fixed without waiting on an outside consultant.

Match the Hire to Your Situation

Not every project needs a full team. Here is a quick way to think about it.

If the work is hidden behind drywall or under finished floors, expect the building official to ask for exposure or testing so inspectors can verify compliance. The details vary by jurisdiction and scope, so ask early.

Step-by-Step: How to Hire the Right Help

Here is a simple order of operations that keeps you from paying twice.

1. Identify the jurisdiction. Confirm which city or county building department controls the property.
2. Check for open permits and violations. Use an open permit search so there are no surprises.
3. Ask the department what is required. Request their after-the-fact or legalization checklist.
4. Get a written scope and fee proposal. It should say who prepares and signs plans, and who manages corrections and final approval.
5. Verify every license. Check contractor, architect, and engineer licenses on the state's official lookup before hiring.
6. Document the existing condition. Your drafter or engineer creates as-built drawings and calculations.
7. Submit, respond, and inspect. Work every reviewer comment, complete corrections, and pass inspections through closeout.

That last step matters. Closeout, meaning final inspection and sign-off, is what truly puts the issue to rest.

What to Look for in Any Pro You Hire

A few green flags make the whole experience calmer.

• Florida-specific experience. Codes, wind requirements, and product approvals differ from other states.
• Clear written scope. You should know exactly what is and is not included.
• In-house sealed drawings. Fewer handoffs mean fewer delays.
• Experience with after-the-fact files. Not every firm takes them on.
• Honest expectations. Good professionals will tell you approval is not guaranteed.

And a few red flags worth walking away from:

• Promises of guaranteed approval or a fixed timeline before seeing the property
• Requests to pay in full with no written scope
• An unlicensed person offering to perform licensed trade work
• Suggestions to skip inspections or hide the original work

What Legalizing Does and Does Not Do

Here is the part nobody loves hearing, but you deserve the straight story. An after-the-fact permit does not automatically erase the original violation, and it does not guarantee the work can stay as built. Depending on the jurisdiction, you may owe fees or penalties, correct deficiencies, or remove and restore noncompliant work.

Pasco County's ordinance is one example: it treats failing to obtain a required after-the-fact permit as a violation and states that paying the fee is not a defense to prosecution. Again, that is a local example rather than a statewide rule, but it shows why talking to your building department early is so valuable.

Fees and timelines also vary widely, because Florida law does not set a single statewide after-the-fact fee. For a deeper look at pricing, see our breakdown of after-the-fact permit costs in Florida.
