Florida Law on Unpermitted Work

Under Florida Building Code (F.S. 553.79), any construction that changes the structure, electrical, plumbing, or mechanical systems requires a permit. Selling a house with unpermitted work isn't illegal, but you must disclose it under F.S. 689.25 (the seller disclosure statute). Failing to disclose known unpermitted work exposes you to fraud claims after closing.

The practical problem: most lenders won't finance a house with unpermitted additions, because the insurer may exclude those areas from coverage. That kills traditional sales. Cash buyers take the risk because we can retroactively permit the work ourselves, or demo it if the cost to permit exceeds the value.

Hialeah: An Unpermitted Addition That Killed 3 Deals

I bought a 3/2 in Hialeah where the previous owner had enclosed the carport into a bedroom and added a bathroom without permits. Three buyers backed out when their lenders flagged it. The seller's agent suggested demolishing the addition, but that would've cost $15K and left them with a 2/1 worth less than they owed.

We bought it as-is, then went through Hialeah's after-the-fact permit process. Cost us $8K and took 6 weeks. The house is now a legal 3/2.

What Counts as Unpermitted Work?

In Florida, most structural changes, additions, and major renovations require building permits. Common unpermitted work includes:

Room additions or enclosed patios, Screened-in porches converted to living space
Bathroom or kitchen remodels, Moving plumbing, adding outlets
Garage conversions, Converting to a bedroom or living area
Electrical or plumbing upgrades, New panels, re-piping
Roofing work, Full re-roofs without permits
Sheds, fences, and driveways, Depending on county requirements

If the previous owner did the work and you weren't aware, you still inherit the issue when you sell.

Florida Disclosure Requirements

Florida law requires sellers to disclose known material defects, including unpermitted work. Failing to disclose can expose you to legal liability after closing.

If you didn't know about the unpermitted work, you're not legally required to disclose it. However, a buyer's inspector or appraiser may flag discrepancies between the property's actual layout and what's on record with the county.

How Unpermitted Work Affects Your Sale Price

Unpermitted work typically reduces your home's value by 10-25% because:

Traditional lenders may refuse to finance the purchase
Appraisers may not count unpermitted square footage
Insurance companies may deny coverage for unpermitted areas
Buyers worry about code compliance and future resale

Retroactive permitting can cost $5,000-$25,000+ depending on the scope and whether the work meets current code. In many cases, selling as-is to a cash buyer is more cost-effective.

Your Options for Selling

You have three main paths:

Option 1: Retroactive Permitting

Apply for after-the-fact permits. This can take 2-6 months and may require bringing work up to current building code, which could mean tearing out and redoing portions.

Option 2: List on the MLS With Disclosure

Disclose the unpermitted work and price accordingly. This limits your buyer pool to cash buyers or those with flexible lenders, and typically extends your time on market.
