13 Pros to Hire for Structural and MEP After the Fact in FL
Not sure who to hire for unpermitted structural and MEP work in Florida? Meet the 13 pros, from engineers to trades, who can legalize it.

Key Takeaways
-
Start with the local building department or code-enforcement office, since it decides what plans, inspections, and fees your after-the-fact permit requires before you hire anyone.
-
Hire a Florida-licensed structural engineer with documented after-the-fact experience to evaluate existing conditions and prepare signed-and-sealed documents where required.
-
Use separately licensed electrical, plumbing, and mechanical contractors for their trades, and verify each license and scope through the Florida DBPR portal before signing.
-
A permit expediter or permitting service coordinates filings and communication but does not replace the engineer or licensed trades who perform technical evaluations and regulated work.
-
Get a written scope naming who inspects, seals plans, pulls trade permits, corrects deficiencies, and closes the permit, so no responsibility falls into a gap.
-
Document concealed work with photos, measurements, and records early, since a well-prepared package with an engineer's evaluation can reduce how much demolition is required.
So the work is already done, and now someone has told you it was never permitted. Maybe you bought the house that way. Maybe a contractor skipped the paperwork. Maybe a closing is stalled and the clock is ticking. Take a breath: this is far more common in Florida than you would think, and it is fixable.
The big question most people ask first is simple: who should I hire for structural and MEP after the fact in Florida? The honest answer is that it takes a small team, not one person. You typically need a Florida-licensed structural engineer, properly licensed electrical, plumbing, and mechanical contractors, and someone to coordinate the whole paper trail with your local building department.
In this guide, we walk through 13 professionals and helpers who can move your project from "unpermitted" to "closed out," what each one actually does, and how to avoid hiring the wrong person first. Whether you are a general contractor, solar company, realtor, or homeowner, you will find a clear path forward below.

Start Here: Why the Building Department Comes First
Before you hire anyone, know who calls the shots. The local building department or code-enforcement office for your city or county decides what evidence, plans, inspections, and fees are required. Hiring before you know the rules is how people pay twice.
Florida law generally requires a permit before covered construction, alteration, repair, or demolition (Florida Statutes §553.79). An after-the-fact permit does not automatically legalize what is already built. The authority may require plans, inspections, corrective work, or even removal if the work cannot be shown to comply.
A quick call or a look at our building department lookup tool can tell you which jurisdiction actually controls your address. That is not always obvious near city lines, and the wrong guess wastes weeks.

The Quick Answer: Who Does What
Here is the big picture at a glance, so you can see where each professional fits.
| Professional | Role in After-the-Fact Work | Needed For |
|---|---|---|
| Florida-licensed structural engineer (PE) | Evaluates existing conditions; prepares or reviews signed-and-sealed documents | Additions, walls, roofs, trusses, slabs, enclosures |
| Licensed electrical contractor | Inspects, corrects, and permits electrical work | Panels, circuits, outlets, solar tie-ins |
| Licensed plumbing contractor | Inspects, corrects, and permits plumbing work | Baths, kitchens, water heaters, drains |
| Licensed mechanical/HVAC contractor | Inspects, corrects, and permits mechanical work | AC replacements, ductwork, ventilation |
| Permitting service | Coordinates records, applications, and communication | Filing, tracking, revisions, closeout |
13 Pros and Helpers to Hire (and When)
1. A Florida-Licensed Structural Engineer
This is the anchor of any after-the-fact structural job. A Florida-licensed professional engineer assesses what is already built and, where the jurisdiction requires it, prepares or reviews signed-and-sealed documents. Ask whether they have real experience documenting concealed or completed work for local after-the-fact permitting, because that is a different skill from designing new construction.
For a deeper look at this role, see our overview of structural engineering services.
2. A Licensed Electrical Contractor
Electrical work must be handled by an appropriately licensed electrical contractor. They can inspect what is in the walls, correct deficiencies, and pull the trade permit. Verify the license and scope through Florida DBPR before you sign anything.
3. A Licensed Plumbing Contractor
Plumbing is its own licensed trade. A plumbing contractor can evaluate unpermitted bathrooms, kitchens, and water heater changes, then bring the work up to code and permit it properly. Do not let a general handyman cover this one.
4. A Licensed Mechanical or HVAC Contractor
HVAC and mechanical work belongs with a mechanical or other properly qualified contractor. Unpermitted AC swaps are among the most common issues we see, and they usually have a clean path to compliance.
5. A Permitting Consultant or Expediter
A permitting service coordinates records, applications, plan submissions, and communication with the jurisdiction. Here is the important part: a permit expediter does not replace the engineer or the licensed trades responsible for technical evaluations and regulated work. They keep everyone moving in the same direction.
That coordination is exactly what our permit facilitation and filing team handles, from application to final inspection.
6. An Architect or Designer (When Appropriate)
Some projects, especially larger additions or change-of-use situations, call for an architect or experienced drafter. They produce the as-built or architectural plan set that the reviewer needs to see. If you already have your own engineer, drafting-only support can give you a permit-ready set without changing who holds the seal.
7. An As-Built Drafter
After-the-fact jobs usually need drawings that show what actually exists, not what someone intended to build. A good drafter measures, documents, and produces as-built drawings that the engineer can then evaluate and seal.
8. A Private Provider for Plan Review and Inspections
In many Florida jurisdictions, a licensed private provider can perform plan review and inspections, which can bypass the county queue. This can be a real time-saver when a sale or lender deadline is looming. Availability and rules vary by jurisdiction, so confirm with your building department.
9. A Surveyor
If your unpermitted work affects setbacks, easements, or lot coverage, an updated survey may be needed. It is one of those supporting players that people forget until the reviewer asks for it.
10. A Third-Party Testing or Inspection Specialist
When work is concealed behind walls or ceilings, the building department may require selective opening, testing, photographs, or independent engineering analysis. A testing specialist can document what is inside so you do not have to tear out more than necessary.
11. A General Contractor for Corrective Work
If the evaluation finds problems, someone licensed has to fix them. A general contractor can coordinate the repairs, bring in the trades, and schedule the inspections. Make sure the contractor accepts responsibility for the work they perform and is clear about what falls to others.
12. A Real Estate Attorney or Title Contact (If Closing)
If you are buying or selling, a real estate attorney can help with disclosure obligations and escrow arrangements. Our realtor closing support pairs well with this step because the permit timeline and the closing timeline need to match.
13. A Code Compliance Specialist
If you already have a notice of violation or a stop work order, someone who knows how to respond to the code officer matters enormously. Our code compliance violation help exists for exactly this moment.
Structural vs. MEP: What Gets Reviewed
Understanding what a reviewer looks at helps you hire the right person first. Here is a simple breakdown.
| Category | Typical Evidence Required | Who Provides It |
|---|---|---|
| Structural | Existing-condition assessment, sealed letter or drawings, load path verification | Structural engineer |
| Electrical | Inspection, corrections, permit, final inspection | Electrical contractor |
| Plumbing | Pressure/drain tests, corrections, permit, final inspection | Plumbing contractor |
| Mechanical | Equipment documentation, duct/ventilation compliance, permit | Mechanical contractor |
| Documentation | As-builts, photos, applications, owner records | Drafter / permitting service |
How to Vet Anyone Before You Hire
Hiring the wrong person is the most expensive mistake in this process. Use this checklist before you commit.
- Verify the license. Check active status and scope through Florida DBPR, and confirm any local licensing requirements.
- Ask for local after-the-fact experience. Request references for similar cases in your jurisdiction.
- Confirm insurance. Get proof, not promises.
- Get a written scope. It should name who inspects, who prepares sealed plans, who pulls trade permits, who coordinates inspections, who corrects deficiencies, and who closes the permit.
- Clarify responsibility. Make sure each professional accepts responsibility only for the work they perform, and that nothing falls into a gap between them.
That written scope is your best protection. If a firm will not put it on paper, keep looking.
What About Concealed Work?
This is the question that makes people nervous. If the work is hidden behind drywall or above a ceiling, the building department may ask for selective opening, testing, or an independent engineering analysis before approving it.
Requirements and fees vary by jurisdiction. For example, St. Lucie County warns that concealed work may require third-party engineering analysis and that after-the-fact permit fees may be doubled. That is a local example, not a statewide rule, so always confirm with your own authority.
The good news? A well-prepared package with photos, records, and an engineer's evaluation often reduces how much demolition is needed. Documentation is your friend.
A Realistic Order of Operations
Here is a sensible sequence that keeps you from spending money out of order.
- Contact the building department to learn what they require for your situation.
- Document existing conditions with photos, measurements, and any receipts or records you can find.
- Hire the structural engineer to evaluate and, if needed, seal the documentation.
- Bring in licensed trades to inspect and correct electrical, plumbing, and mechanical work.
- Submit the application with plans, letters, and trade permits.
- Schedule inspections and respond to any reviewer comments.
- Close the permit and confirm the final approval is on record.
If it feels like a lot of moving parts, that is exactly why many people hire a coordinator. We often say a permitting service is the conductor, and the engineer and trades are the musicians.
Who Needs What: A Quick Audience Guide
- General contractors: You may already hold trade relationships, but you still need a sealed engineering path and clean filing. See our page for general contractors.
- Solar companies: Structural roof evaluation and electrical documentation are the usual hurdles. Our solar contractor support addresses both.
- Realtors and investors: Speed and certainty matter most. Early research prevents closing surprises. Learn more for realtors.
- Homeowners: You need a guide who explains each step in plain English. Start with our homeowner resources.
What It May Cost and What Affects It
Costs swing widely, so be wary of anyone who quotes a single flat number without seeing the property. After-the-fact permit fees can be higher than standard fees, and local penalties vary. Engineering scope, concealed conditions, and corrective work are the biggest cost drivers.
For a deeper breakdown, read our guide on after-the-fact permit costs in Florida. And if you want a sense of how the legalization process flows, our article on how to legalize unpermitted work in Florida is a helpful companion.
One more note on paperwork: a Notice of Commencement is generally required before the first inspection when the direct contract exceeds $5,000 (Florida Statutes §713.135). Confirm applicability for your project.
Red Flags to Avoid
Not every helper is a good helper. Watch for these warning signs.
- Anyone who promises the permit will be approved before reviewing the work.
- A "one person does it all" pitch that skips licensed trades.
- No written scope or unclear ownership of inspections.
- Pressure to skip the building department and "just fix it quietly."
- License numbers that do not check out on DBPR.
Remember, the local authority has the final say. Anyone who tells you otherwise is selling something.

FAQs
Who should I hire to legalize unpermitted structural work in Florida?
Start with a Florida-licensed structural engineer who has experience documenting completed or concealed work. They can evaluate existing conditions and prepare signed-and-sealed documents when your jurisdiction requires them. A permitting service can then coordinate the filing and inspections.
Can a Florida permitting service pull an after-the-fact permit for me?
Yes, a permitting service can coordinate records, applications, plan submissions, and communication with your building department. But it does not replace the engineer or licensed trade contractors who handle technical evaluations and regulated work. Think of it as the coordinator that keeps everyone on track.
What happens if unpermitted work is hidden behind walls or ceilings?
The building department may require selective opening, testing, photos, records, or an independent engineering analysis before approving it. Requirements and fees vary by jurisdiction, so check with your local authority. Good documentation often reduces how much has to be opened up.
How do I verify a Florida contractor or engineer's license?
Use the Florida DBPR licensing portal to confirm active license status and scope for contractors, and check for any local licensing requirements too. Also ask for proof of insurance and references from similar local cases. A quick check up front can save you from a very expensive do-over.
Can the building department make me remove unpermitted work?
Yes, it can. An after-the-fact permit does not automatically legalize existing work, and if the work cannot be shown to comply, the authority may require corrections or removal. Hiring the right engineer and trades early gives you the best chance of keeping what you built.
