5 Pros Investors Should Hire for Unpermitted Flip Fixes in FL

Key Takeaways

• Hire a permitting partner first to research permit history, identify the correct building department, and set the path forward before you finalize any repair budget.

• Use a small team: a Florida-licensed general contractor with corrective permitting experience, plus a licensed engineer or architect/drafter when the jurisdiction requires plans or certification.

• Structural changes like removed load-bearing walls, garage conversions, and additions usually require a licensed engineer to certify the work, while cosmetic jobs often need no permit.

• Verify every contractor's license through the Florida DBPR search, confirm local registration, and avoid anyone who says permits are unnecessary or asks you to pull an owner-builder permit for their work.

• Regulated trades like electrical and plumbing need their own licensed contractors, with written scopes stating who pulls the permit and payments tied to passed inspections.

• An after-the-fact permit is not automatic; expect possible plan requirements, exposed concealed work, penalties, and inspections, so talk to the jurisdiction before budgeting and avoid closing walls too soon.

You closed on a Florida flip, the numbers looked great, and then someone pulled the permit history. Now there is a finished bathroom with no permit, a converted garage nobody inspected, or a panel upgrade that never saw an inspector. Take a breath. This happens to smart investors every single week, and it is fixable.

The real question is not whether you can fix it. It is who should investors hire for unpermitted flip fixes in Florida, and in what order. Hire the wrong person first, and you can burn weeks and thousands of dollars on work the building department will not accept.

In 2026, the answer is usually a small team rather than a single hero: a licensed contractor, a licensed design professional when the jurisdiction requires one, and a permitting partner who keeps the paperwork moving. Below, we walk through the five pros worth hiring, what each one actually does, and how to sequence them so your flip gets to a closed permit and a clean sale.

Why Unpermitted Work Is Not Just a Paperwork Problem

Florida Statutes §553.79 generally prohibits covered construction, alteration, repair, or demolition without first obtaining a permit from the appropriate enforcing agency. Because enforcement is local, the city or county building department decides what your path looks like. There is no single statewide process that guarantees approval.

That matters for flippers because unresolved violations can lead to enforcement action, extra costs, delays, and complications with sale or refinancing. West Palm Beach, for example, says unpermitted work may trigger a compliance case, penalty fees, daily fines, and a lien. That is a local example, not a statewide fee schedule, but it shows how quickly a small problem can grow.

If you want a deeper walkthrough of the legal side, our guide on unpermitted work in Florida and how to legalize it covers the fundamentals.

The Quick Answer: Your Hiring Team at a Glance

Before we dive into each role, here is the short version. Most investors need some combination of these five professionals.

Notice what is missing: a handyman or a friend who "knows a guy at the city." Those shortcuts are how flips end up with a second unpermitted problem stacked on the first.

1. A Permitting Partner Who Does the Detective Work First

Think of this person as your project quarterback. Before anyone swings a hammer, you need to know what was done, when it was done, and which authority controls the fix. That is harder than it sounds, especially near city lines where the property may sit in a different jurisdiction than the mailing address suggests.

A good permitting partner will:

• Identify the correct building department for the address
• Pull permit history, open permits, and code enforcement records
• Compare those records against seller disclosures and any available plans
• Explain the likely path, including whether the jurisdiction allows after-the-fact permitting
• Prepare and file the application, then track it and answer reviewer comments

This is exactly what permit facilitation and filing is built for. At 1 Contractor Solutions, we act as an outsourced permitting department, so investors get one team handling research, drawings, filing, and revisions rather than juggling four vendors.

If the property already has an open or expired permit on file, our open permit search tool is a handy first stop.

Why Hire This Role First

Because every dollar you budget depends on what the building department says. A written assessment from the jurisdiction or qualified professionals should come before you finalize your repair budget. Skipping this step is the single most common reason flip budgets blow up.

2. A Licensed General Contractor With Corrective Permitting Experience

Next comes the person who actually fixes things. For a Florida flip with work done without required permits, investors should generally hire a Florida-licensed general contractor who has real experience with corrective or after-the-fact permitting. That experience is not the same as new construction experience. Corrective work means opening walls, documenting what is inside, and satisfying inspectors who are seeing the project for the first time.

A qualified contractor can assess scope, coordinate trades, prepare a correction plan, apply for permits, and arrange inspections. Just make sure they hold the appropriate active license and are authorized to qualify the business named in your contract.

How to Verify Before You Sign

Do not rely on a business card or a verbal promise. Use the Florida DBPR license search to confirm the license is active and matches the company name. Then check local registration requirements, since many municipalities require separate registration. Our contractor registration checklist and our article on Florida contractor license requirements can help you ask the right questions.

Red flags to walk away from:

• A contractor who says permits are "not really needed" for your scope
• Anyone asking you to pull an owner-builder permit for work they will perform
• No written scope, no inspection milestones, or vague payment terms
• A license that is expired, inactive, or belongs to someone else

3. A Licensed Engineer Who Can Seal What Is Behind the Walls

Here is where many flippers get surprised. The building department may not simply accept your word, or even your contractor's word, that the structure is sound. When the work involves framing changes, removed walls, a garage conversion, an addition, roof structure, or load-bearing modifications, the jurisdiction often requires a Florida-licensed engineer to evaluate and certify it.

An engineer can inspect the existing conditions, prepare an engineer letter, and design corrections if something falls short. Our structural engineering and MEP engineering teams do this in house, which means our own engineer signs and seals the work. For investors, that speed matters, because an outside consultant who takes two weeks to call back can cost you a lot in carrying costs.

If your reviewer only needs a professional opinion rather than a full redesign, an engineer letter may be the lighter-weight route. Our article on who writes engineer letters for Florida permits explains the difference.

When an Engineer Is Usually Required

The final column is the key. Requirements vary by jurisdiction and by project, so treat any table like this as a starting point, not a promise. Seminole County, for instance, lists strictly cosmetic painting or flooring as examples that may not need permits, while electrical repairs and whole-window replacement generally do.

4. An Architect or Drafter for As-Built Drawings

Reviewers cannot evaluate what they cannot see. For most after-the-fact applications, the building department wants drawings that show what actually exists on the property. These are called as-built drawings, and they are different from design plans for something you plan to build.

An experienced drafter or architect will measure the property, document the existing layout, and prepare a drawing set that matches your jurisdiction's submittal checklist. Good as-builts reduce back-and-forth with plan reviewers, which is where much of the delay in this process lives.

Our as-built drawings and architectural drafting services are designed for exactly this situation. If you already have an engineer you trust, our drafting-only option lets us draw the permit set while your engineer keeps their seal and their relationship with your project.

What a Strong As-Built Package Includes

1. A site plan showing the property boundaries, structures, and setbacks
2. Floor plans with dimensions, room labels, and any altered areas clearly marked
3. Elevations, sections, or details where structural or wind-load questions exist
4. Electrical, plumbing, and mechanical information if those trades were touched
5. Notes tying the drawings to the specific code items the reviewer will check

5. Separate Licensed Trade Contractors for Regulated Scopes

The last role is the one flippers most often try to skip. Electrical, plumbing, mechanical, and roofing are regulated trades, and the corrective permit generally needs a properly licensed contractor in that trade to take responsibility for the work.

A general contractor can coordinate these trades, but they should not replace them where a separate license is required. For each trade contractor, confirm:

• An active Florida license for that specific trade
• Current insurance, including workers' compensation or a valid exemption
• A written scope that says who pulls the permit
• Defined inspection milestones, such as rough-in and final
• Payment terms tied to passed inspections, not just calendar dates

Be especially careful with electrical and plumbing, because these are the areas inspectors scrutinize most closely when walls were closed without an inspection. Our guide on unpermitted electrical work in Florida shows what reviewers tend to look for.

The Smart Hiring Sequence for Investors

Order matters as much as who you hire. Here is a practical sequence that keeps you from paying twice.

1. Identify the local authority. Confirm which city or county actually controls the property. Our building department lookup helps with this.
2. Gather records. Pull permit history and code enforcement files, and compare them to seller disclosures.
3. Hire a licensed contractor for a documented site assessment. Get the scope in writing.
4. Add an engineer or architect if needed. Do this when the department requires plans, evaluation, or certification.
5. Submit the jurisdiction's required permit package. Use a permitting partner to file and track it.
6. Complete approved corrections. Expose concealed work if the inspector asks.
7. Pass inspections and close the permit. Keep the final approvals for your resale records.

Pinellas County's building FAQ notes that its permits expire six months after issuance or the last approved inspection, unless the building official grants a written extension. That is a county-specific example, but it is a good reminder: once your permit is open, keep the work moving, or you may be back for an extension. If a permit does lapse, see our guide on how to close an expired permit in Florida.

Do Not Assume an After-the-Fact Permit Will Simply Legalize the Work

This is the part we want every investor to hear in a friendly but firm voice. An after-the-fact permit is not a rubber stamp. The jurisdiction may require plans, engineering, exposed concealed work, corrections to current code, inspections, fees or penalties, and in some cases removal and reconstruction.

West Palm Beach, as one local example, reports a possible penalty of four times the regular permit fee for unpermitted work. Other jurisdictions handle it differently. That is why we always encourage investors to talk to the jurisdiction before budgeting. Our overview of the after-the-fact permit cost in Florida and our post on penalties for building without a permit can help you plan realistic numbers.

Matching the Problem to the Right Pro

Every flip has its own quirks. Use this table as a rough guide to where to start based on what you found.

Common Mistakes Investors Make

A few patterns show up again and again. Avoid these, and you will already be ahead of most flippers.

• Budgeting before investigating. Numbers set before the jurisdiction weighs in are guesses.
• Closing walls too soon. If an inspector needs to see inside, you will be tearing out fresh drywall.
• Hiring on price alone. The cheapest bid often skips permits, which is how you got here.
• Using one vendor for everything. A GC is not a substitute for a licensed engineer or a licensed electrician where the law requires one.
• Forgetting the paper trail. Closed permits and final approvals are what make your resale smooth.
