Selling a House With an Unpermitted Addition in Florida

Cash Flow Deals locks your net price on a Florida house with an unpermitted addition before the permit issue is resolved. An unpermitted addition does not stop a sale by itself. It does mean the added square footage usually will not count toward appraised value, and most lenders will not fund a buyer's loan until the work is resolved or excluded.
| Factor | Traditional Listing | Cash Flow Deals |
|---|---|---|
| Timeline | FHA lenders in particular pause or deny funding once an appraiser flags unpermitted work, often forcing a relist or a search for a buyer who does not need a mortgage; VA and conventional lenders are generally more flexible if the space meets safety standards. | Net price locked at signing, before the unpermitted work is scoped and priced. |
| Repairs | Buyer may demand the addition be retroactively permitted, brought to code, or removed before closing. | Work is re-costed only if something structural is found; otherwise the price holds. |
| Fees / Costs | Commission is negotiable since the Aug. 17, 2024 NAR Sitzer/Burnett settlement, plus the seller often eats the cost of retroactive permitting or a price cut for the missing square footage. | Flat fee arranged through Silver Door Realty, listed as its own line item on the closing statement, not a markup on price. |
Why an Unpermitted Addition Complicates a Florida Sale
An unpermitted addition is work done on the house, a room, a garage conversion, an extra bathroom, that was never inspected and signed off by the local building department. The square footage exists, but the county's record of the house does not show it. Cash Flow Deals treats a property with an unpermitted addition the same way it treats any Florida house: the net price gets locked before that work is scoped or priced, and the seller decides how to move from there.
How an Unpermitted Addition Affects Appraisal and Financing
Appraisers typically will not credit unpermitted square footage toward a home's value, even when the addition was expensive to build and looks finished. FHA lenders in particular will not finance a property with known unpermitted work until it is resolved, which usually means the buyer either pays without a mortgage or the seller fixes the permit problem first. VA and conventional lenders are generally more flexible if the space meets safety standards, but the FHA gap alone shrinks the pool of buyers who can even make an offer, and it tends to invite lowball numbers from the ones who do.
What Florida Disclosure Law Requires You to Tell a Buyer
Under Johnson v. Davis, the Florida Supreme Court's 1985 ruling, a seller must disclose facts known to them that materially affect the property's value and are not readily observable to the buyer. An unpermitted addition, along with unpermitted electrical, plumbing, or roofing work behind it, fits that description. Florida's First District Court of Appeal confirmed in Rayner v. Wise Realty Co. of Tallahassee that selling a house 'as is' does not waive that duty. A buyer who signs an as-is contract still has not agreed to eat an undisclosed unpermitted addition they never knew about.
Cash Flow Deals' Process for a Property With an Unpermitted Addition
Cash Flow Deals is a Florida real estate investor that locks in a net price for a seller's house before repairs are scoped, using a novation-based, flat-fee process arranged through its licensed FL brokerage partner, Silver Door Realty — not a traditional listing, and not a brokerage itself. Cash Flow Deals' Process: 1. Request your net-price walkthrough, where the unpermitted addition gets disclosed upfront. 2. Cash Flow Deals arranges the locked net price through Silver Door Realty before the permitting or repair work is scoped or priced. 3. Title transfers once, directly from seller to the real FHA or conventional buyer whose own lender funds the purchase, once financing conditions are met. 4. Cash Flow Deals gets paid as a separate line item on the closing statement, never as a markup on your price.
What Happens If the Addition Turns Out to Have a Structural Problem
A locked net price stays locked. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens. For an unpermitted addition specifically, that means a foundation tie-in or wiring problem discovered once the work gets inspected is re-costed and brought back to the seller, not buried inside a lower number at closing.
Common questions
Do I have to disclose an unpermitted addition when I sell my house?
Yes. Under Johnson v. Davis, Florida sellers must disclose known facts that materially affect a property's value and are not readily observable to the buyer, and Florida courts have confirmed an as-is sale does not waive that duty.
Will an unpermitted addition kill my buyer's FHA loan?
It often will unless the work is resolved or excluded from the valuation first. FHA lenders in particular generally will not fund a property with known unpermitted work, while VA loans are more flexible if the space meets safety standards.
Does the added square footage count toward my home's appraised value?
Usually not. Appraisers typically exclude unpermitted square footage from the valuation even when the addition was expensive and looks finished.
Can I sell without fixing the permit issue on the addition first?
Yes, to a buyer who does not need financing, or through a process like Cash Flow Deals' locked net price, subject to disclosure. A buyer relying on a traditional mortgage will usually need the issue resolved or credited before their lender funds.
