The shortcut is cheap on the day you take it
The decision is rarely dramatic. A garage gets enclosed. A patio becomes a family room. A bathroom appears where a closet used to be. A re-roof happens over a weekend with a crew somebody recommended. Nothing goes wrong, the work functions, years pass, and nobody thinks about it again.
Then the house goes on the market and the shortcut becomes the most expensive item in the transaction — not because a code official knocks on the door, but because a buyer, a lender, an insurer and a public records search all arrive in the same few weeks and start comparing what physically exists to what is documented. Our overview of permitting in Miami-Dade covers how that process is supposed to run. This is what happens when it did not.
One note before the detail: everything below is construction and permitting process, which is our lane. How an unpermitted-work issue affects your specific contract, your disclosure obligations or your negotiating position is a question for your real estate attorney and your agent, and it is worth asking early rather than the week before closing.
How unpermitted work actually gets discovered
Owners tend to imagine discovery as an enforcement event. In practice it is almost always a transaction event, and it arrives from one of four directions.
The buyer’s inspection
A competent inspector reads a house against itself. Finishes newer than the rest of the home. A room with a different ceiling height or floor level. A bathroom with a drain run that could not have been original. A panel with obvious later additions. The report does not have to use the word “unpermitted.” It only has to describe something that prompts the buyer’s side to ask the county what is on file.
The appraisal and the buyer’s lender
Appraisals are written against public records. When the county shows fewer bedrooms, fewer bathrooms or less square footage than the appraiser is standing in, that discrepancy goes in the report. Lenders read those reports closely, because the collateral has to be the thing described in the file. To a lender, an unpermitted addition is not a code philosophy question. It is an unresolved question about what they are lending against.
Insurance underwriting
The buyer needs a policy in order to close. In South Florida, underwriting asks pointed questions about the roof, the openings and any structural alteration, and those questions get answered with documentation rather than description. Roofing and openings carry product approval requirements here, and an approval never submitted with a permit generally cannot be reconstructed afterward. The record either exists or it does not, and that was settled during construction.
The county’s own records, often triggered by your next permit
This one catches sellers trying to do the right thing. You apply for a permit to remodel the kitchen before listing, and the review compares your address against its own history. Old open permits, expired permits with no final inspection, and structures that do not appear in the file can all surface right then, and the new application can end up waiting on the old problem. Applying did not create the exposure. It made it visible.
Does unpermitted work show up in a home inspection or a title search?
Unpermitted work usually surfaces through the buyer’s inspection, the appraisal, or a search of county building records, rather than through the title search. Title work addresses ownership, liens and encumbrances; it does not report whether a bathroom or an enclosure was ever permitted. The building department’s file is where that answer lives.
A home inspector reports conditions, not permit status. But a description of an enclosed patio or an added bathroom is enough for the buyer’s agent to pull the property’s permit history, which is public record in Miami-Dade and straightforward to check.
Title work can catch related items — a recorded code enforcement lien, an open violation — which is why it sometimes gets the credit. The more common path is simpler: somebody compares the county’s record of the house to the house.
- The inspection describes a condition that does not match the records
- The appraisal notes bedroom, bathroom or square footage discrepancies
- County permit history shows missing, open or expired permits
- Underwriting requests documentation that does not exist
- A new permit application triggers a records review
What a lender or an insurer asks for
Neither party is punishing anybody. Both are removing uncertainty from a file, and unpermitted work is uncertainty they cannot quantify. That mechanism explains every response that follows.
A lender’s options are limited and predictable. It can require the work to be legalized before closing. It can require it removed or restored to the documented condition. It can hold funds in escrow. It can decline to assign value to the unpermitted space. It can decline the loan. Any of those reshapes the deal, and most of them land on the seller, because a buyer with a financing contingency has somewhere else to go and the seller does not.
Insurance underwriting runs on the same documents. Where an alteration touched the building envelope, roofing, windows and doors, an enclosure that changed an exterior wall, underwriting asks for evidence the work was built and inspected to the requirements that apply here. What any given carrier does with a gap in that record is a question for the carrier, and the buyer will be asking it. What a builder can tell you is the part we control: that record gets produced during construction, and nobody can recreate it afterward. Cash buyers price the problem instead, and they price it in their own favor, because they are absorbing a scope nobody has defined.
Permitting it after the fact: what the process involves
After-the-fact permitting is a real path rather than a loophole, and it is how most of these situations get resolved. The shape is consistent, even though every municipality inside the county runs its own building department with its own submittal requirements and interpretations.
First the existing condition has to be documented, because a building department cannot review what nobody has drawn. That generally means a licensed contractor and, wherever structure is involved, a Florida-licensed engineer or architect measuring what is actually there and producing sealed drawings of it. Then a permit is opened for the work as built, in the correct jurisdiction, by a licensed qualifier.
The difficult part is verification. A permit closes on inspection, and an inspector has to see what is behind the finished surfaces: framing, structural connections, electrical and plumbing rough-ins, waterproofing. Sometimes that is satisfied with limited openings and engineer observation. Sometimes it means removing finishes to expose the assemblies, which is exactly why legalizing old work is more disruptive than permitting it correctly would have been.
What decides it is whether the work is permittable as built, and that is a question about the work rather than about the process. Plenty of unpermitted construction was competently done and simply never reviewed; plenty of it conflicts with zoning, setbacks, height, occupancy or egress, and no amount of correction makes it compliant where it stands — the remedy there is modification or removal. On additions and structural work that assessment is where we start, because it governs everything after it and nobody should be told how it lands before it has been made.
- Document what exists, with sealed drawings where structure is involved
- Open a permit for the work as built, in the correct jurisdiction
- Expose or otherwise verify the concealed work so it can be inspected
- Correct whatever does not meet current requirements
- Pass finals and get the certificate into the property’s permanent record
Who can close an open permit the previous owner never finished?
A licensed contractor closes it. The original permit holder can come back and call the remaining inspections, and where that company is gone or unwilling, another licensed contractor takes the permit over in the correct jurisdiction. Some departments will also review very old permits administratively where no safety issue is apparent. Start by asking what your jurisdiction requires.
An open permit is a better problem than unpermitted work, because the drawings and the approvals already exist. What is missing is usually the last inspection or two, and sometimes only the final. Pull the permit record first and read which inspections were passed, since that tells you whether this is a scheduling problem or a scope that has to be opened back up.
A contractor taking over somebody else’s permit is accepting inspection responsibility for work they did not build, so expect them to look before they agree. That is not reluctance, it is the same judgment any licensed qualifier has to make. Where the concealed work cannot be verified as it stands, limited openings or engineer observation is often what makes the inspection possible.
Buyers of Florida property have some protection from being penalized for a prior owner’s unclosed permit, but the permit still sits on the property, and a building department can decline to issue your next one until it is resolved. Ask your attorney where you stand on the transaction; ask a contractor what closing it involves.
Why “the last owner did it and it has been fine for years” is not a defense
This is the most common thing sellers say, and it is completely understandable. It is also irrelevant to the mechanism. A permit record attaches to the property, not to the person who did or did not obtain one. Time does not convert unpermitted work into permitted work, and a room functioning well for years is not the independent verification that permitting exists to provide.
It is worth being precise about what the buyer’s side is reacting to. They are not offended on the county’s behalf. They are looking at concealed construction nobody ever inspected and reasonably concluding they cannot tell what is behind it. The garage conversion may be beautifully built. From the outside of the drywall it is indistinguishable from one that is not, and that is the exact problem permitting solves.
What a seller should do before listing
The entire difference between a manageable construction project and a bad negotiation is timing. Before listing, this is a scope you control: you choose the contractor, the sequence, the schedule and how much of the house is disturbed at once. Under contract it becomes a deadline problem with a counterparty who now has reasons to renegotiate other things too.
So start with the record. Miami-Dade property and permit records are public, and pulling the history for your address costs nothing but attention. Read it against the actual house — bedroom and bathroom counts, square footage, enclosures, the roof, the openings, pools, decks and fences. Look specifically for permits that were opened and never closed, which are common, frequently forgotten, and usually simpler to resolve than work never permitted at all.
- Pull the permit history for the property and compare it to what physically exists
- Separate open or expired permits from work that was never permitted — different problems
- Have a contractor, and an engineer where structure is involved, assess what legalizing requires
- Decide before listing whether to legalize, modify, remove, or disclose and price accordingly, with your attorney and agent advising the transaction side
- Keep closeout documents, sealed drawings and product approvals together for the buyer’s lender and insurer
For owners about to remodel anyway, the cleanest version of this is to fold the legalization into the project. If walls are coming open in the kitchen, that is the least expensive moment in the property’s life to also address the addition nobody ever permitted. We handle that sequencing on remodels, on additions and structural work, and on ground-up construction throughout Miami-Dade County; how we run projects is described on our company page. If you already suspect something on your property is not documented, request a proposal and we will assess the permitting path while it is still a construction question rather than a closing one.
