Florida Mold Disclosure Law What Sellers Must Know

Published June 11, 2026  |  Home Enviro

Florida Real Estate Disclosure Requirements

Florida follows a doctrine of seller disclosure that requires property sellers to disclose known material defects that are not readily observable and that may affect the value or desirability of the property. This duty was established through the Florida Supreme Court case Johnson v. Davis, and it applies broadly to residential real estate transactions.

Mold constitutes a material defect under this framework. A seller who is aware of mold contamination in their property, or who should reasonably have known about it, is required to disclose this information to prospective buyers before or at the time of contract. Failure to disclose a known material defect can expose sellers to claims for fraud, misrepresentation, or breach of contract after closing.

What Sellers Must Disclose About Mold

Sellers must disclose any known mold contamination, the history of water damage or moisture intrusion events that could have led to mold growth, any remediation work that was conducted including the scope and whether clearance testing was done, and any recurring moisture problems such as chronic roof leaks, plumbing issues, or HVAC condensation problems.

The disclosure obligation is limited to what the seller actually knows or reasonably should have known. A seller who has genuinely never had a mold issue and has no knowledge of hidden contamination has nothing to disclose. However, a seller who had remediation performed and did not follow up with clearance testing may face difficulties demonstrating that they believed the problem was fully resolved.

Protecting Yourself as a Seller

The most effective way for a seller to protect themselves from post-closing mold claims is to commission an independent pre-listing mold inspection. If the inspection reveals mold, address it and commission a clearance test before listing. If the inspection is clean, the documentation provides concrete evidence that the property was professionally assessed and found free of contamination at the time of listing.

This approach reduces the likelihood of buyer-side mold findings disrupting a transaction at a critical point, potentially eliminates a common negotiating tool buyers use to request price reductions, and provides documented protection against post-closing claims.

What Buyers Should Understand

Buyers should not rely solely on seller disclosure as protection against mold problems. Sellers can only disclose what they know. An independent mold inspection conducted during the inspection contingency period is the buyer's own protection, regardless of what the seller has disclosed.
