Mold and Water Damage Disclosure in Florida Real Estate

Does Florida Require Sellers to Disclose Mold?

The short answer: yes, even without a dedicated mold statute. Florida has no law that specifically says "disclose mold" the way California's Civil Code §1102.6 does. What Florida does have — and has had since 1985 — is Johnson v. Davis, a Florida Supreme Court decision that created a broad duty to disclose any material defect that affects the property's value and is not readily observable by the buyer.

Water damage and mold fall squarely inside that rule. If a seller knows there is active mold behind a wall, under the flooring, or inside the HVAC ductwork, that seller has a legal obligation to disclose it. Past remediation counts too — if you had mold treated three years ago, you need to tell the buyer.

I am not a lawyer, and nothing here is legal advice. If you are selling a home with a known mold or water issue, talk to a Florida real estate attorney before you fill out the disclosure form. What I can do is give you the practical picture of how this plays out in real transactions across Tampa Bay and Central Florida.

Johnson v. Davis: What the Case Actually Requires

Johnson v. Davis (Fla. 1985) came out of a Broward County transaction where sellers assured buyers there were no roof problems — and then the roof leaked badly after closing. The Florida Supreme Court held that sellers have a duty to disclose facts that materially affect property value when: (1) the seller knows about them, (2) the facts are not readily observable to the buyer, and (3) the buyer would not be expected to discover them in a normal walkthrough.

Before that decision, Florida followed caveat emptor — buyer beware. The buyer's only protection was their own inspection. Johnson v. Davis changed that fundamentally.

For mold and water damage, the test is straightforward. If you smell it, see the stain, or know the remediation company's invoice is sitting in your file cabinet, that is knowledge you are required to share. The defect does not need to be visible right now to trigger disclosure — it just needs to be something you know about.

• Active mold growth anywhere in the home, including HVAC systems and ductwork
• Prior mold remediation, regardless of how long ago it was performed
• Recurring roof leaks, even if patched, that caused water to enter the structure
• Plumbing failures that led to water intrusion inside walls, cabinets, or flooring
• A/C condensate drain backups that caused moisture damage
• Known moisture problems that have not yet produced visible mold but are creating conditions for it

The FAR/BAR Seller Disclosure Form and What Triggers It

Most Florida residential transactions use the FAR/BAR contract (Florida Realtors / Florida Bar joint form). The Seller's Disclosure form that accompanies that contract asks sellers to check yes or no on a range of known defects — including water intrusion, drainage issues, and environmental hazards.

The specific questions you will see include: Has the property experienced any water intrusion or flooding? Are there any known moisture, mold, or mildew problems? Have there been any leaks in the roof, walls, or plumbing? Has any environmental remediation been performed on the property?

If you check no on any of those when the honest answer is yes, you are potentially creating a misrepresentation claim that survives closing. That exposure does not go away once the title changes hands.

One nuance: there is also a FAR/BAR Mold Inspection Rider (form CR-6_I) that allows buyers to negotiate an explicit mold inspection period separate from the general home inspection window. If you are a buyer and the seller's disclosure has any water-related items checked, ask your agent to include this rider. It gives you a dedicated window to bring in a licensed mold assessor without burning your general inspection contingency.

What Buyers Should Order — and What It Costs

A standard home inspection covers visible water staining, obvious moisture evidence, and accessible areas. But inspectors are not licensed mold assessors and cannot take air samples or issue clearance certificates. For any home where the seller has flagged water issues — or where you spot the signs yourself during a walkthrough — you need a separate mold inspection.

What to Look for During Your Walkthrough

Before you even get to inspection day, pay attention during your initial tours. The physical signs that warrant a follow-up are not subtle once you know what you are looking for.

• Water staining on ceilings, especially around ceiling fans, light fixtures, and HVAC vents
• Discoloration or bubbling around bathroom tiles, window frames, and exterior doors
• Rust or standing water in the A/C drip pan — visible if you look under the air handler
• Drywall that feels soft or has visible bubbling — press gently on walls near windows and plumbing walls
• A musty smell in closets, under sinks, or in the garage — especially in older homes
• Dark streaking on exterior stucco, particularly around window sills and roof transitions
• In older homes: efflorescence (white mineral deposits) along the base of block walls, which indicates moisture migration through the structure

Any of those signs warrants asking the seller directly and scheduling an air quality test.

Mold Inspection Costs in Tampa Bay and Central Florida

A full air-quality mold inspection — visual assessment, moisture meter readings, and two air samples sent to an accredited lab — runs $300 to $600 in the Tampa Bay and Orlando market. The price varies by home size, the number of samples taken, and how quickly you need lab results back.

Post-remediation clearance testing runs $250 to $500. This is the test that matters most: a licensed Florida Mold Assessor performs it after remediation is complete to verify spore counts have returned to baseline. If a seller is trying to sell a remediated property, they should have a clearance certificate from that test. Ask for it.

For reference, remediation itself costs $1,500 to $6,000 for contained issues in Tampa Bay. Extensive cases — a flooded crawl space after a hurricane, water intrusion across multiple rooms — can exceed $10,000.

Post-Ian and Post-Helene: The Hidden Water Intrusion Problem

Hurricanes Ian (2022) and Helene (2024) created a specific disclosure problem that is still working through the Tampa Bay market. Homes that had water intrusion during those storms — even homes that were professionally dried out — can have mold developing behind drywall, inside wall cavities, and under flooring for months or years afterward.

The remediation industry standard is to remove drywall at least two feet above the waterline, because moisture trapped inside wall cavities produces visible mold spores within three to seven days. But not every homeowner who had water in their house did that. Some homes were partially dried, painted over, or had flooring replaced without addressing the structural moisture.

“A seller who had water enter their garage during Helene and mopped it up without testing the wall cavity — and then did not disclose it — is walking a real legal line under Johnson v. Davis.”

If you are buying in Shore Acres, Venetian Isles, the flood-prone sections of New Port Richey, or any coastal community in Hillsborough or Pinellas County, I strongly recommend ordering a mold inspection on every offer. Not just the homes where the disclosure says yes. The ones where nothing is checked sometimes have the most to find.

Florida Mold Assessor Licensing Rules — Why They Protect You

Florida is one of the few states with a mandatory licensing framework for mold professionals. Under Chapter 468, Part XVI of the Florida Statutes, anyone who performs mold-related services on areas greater than 10 square feet must hold an active license issued by the Florida Department of Business and Professional Regulation (DBPR).

There are two separate license types: Mold Assessor (the person who tests, samples, and writes the assessment report) and Mold Remediator (the person who performs the cleanup and remediation work). The law prohibits the same company from performing both the assessment and the remediation on the same property within a 12-month period. This is a consumer protection built into the statute — it prevents a company from diagnosing a problem they are also paid to fix.

When you hire for a mold inspection, verify the assessor license through the DBPR website (myfloridalicense.com). You are looking for an active Mold Assessor license under FL Statute 468. If the person only has a general contractor or home inspector license, they cannot legally provide the certified assessment you need.

The clearance test after remediation must also be performed by a licensed Mold Assessor — not the remediator who did the work. If a seller hands you a clearance letter signed by the same company that did the remediation, that clearance is not legally valid in Florida and should be a red flag.

The HOA and Condo Wrinkle

Mold disclosure in condominiums and HOA communities adds a layer that single-family transactions do not have. When the source of water intrusion is a common element — the roof, an exterior wall, shared plumbing risers — the question of who is responsible for the damage becomes a conversation between the unit owner and the association.

Under Florida Statute 718.111(11), condo associations are generally responsible for the repair and replacement of drywall within the units when damage originates from a common element failure. The unit owner is responsible for finishes — paint, wallpaper, tile — but the drywall substrate itself is the association's responsibility in most Florida condo documents.

In practice, this means a seller of a condo who had a roof-sourced leak is not necessarily the one who pays for remediation — but they are still the one who has to disclose what happened. The distinction matters at closing: a buyer needs to understand whether the association has addressed the root cause (the roof), whether the association's master policy covers the remediation, and whether there are any open claims with the association that affect the unit.

For single-family homes in HOAs, the calculus is simpler — the homeowner owns the structure, so disclosure and remediation responsibility both rest with the seller. HOA common areas such as pool equipment rooms, garages, and covered walkways are association responsibility, but those rarely affect a home's marketability unless there is active leakage into a unit.

Before buying a condo, ask for the association's most recent reserve study, any open insurance claims, and the meeting minutes from the past 12 months. Water intrusion and mold issues in common elements get discussed in board meetings — and those minutes are a disclosure document the seller does not have to hand you, but the association does have to share.

Frequently Asked Questions

Does Florida law require sellers to disclose past mold remediation?

Yes, under Johnson v. Davis. If you had mold remediated and you still own the property, that is a material fact that affects the property value. It does not matter how long ago the remediation was or whether you have a clearance certificate — the buyer is entitled to know it happened. The clearance certificate actually helps sellers because it proves the issue was professionally resolved.

Can a buyer back out of a contract because of mold found during inspection?

It depends on the contract terms. Under the standard FAR/BAR AS-IS contract, the buyer can terminate for any reason during the inspection period and receive their deposit back. If mold is discovered after the inspection period closes, the buyer's options depend on whether the seller failed to disclose a known issue — in which case there may be a misrepresentation claim — or whether it was a genuinely new discovery.

Is a mold inspection the same as a regular home inspection?

No. A home inspector is trained to identify visible signs of moisture and flag areas of concern, but they are not licensed to take air samples, analyze spore counts, or issue a mold assessment report. For those services, you need a licensed Florida Mold Assessor under Chapter 468. The cost is $300 to $600 for an initial assessment including air sampling and lab analysis.

Who orders the mold clearance test after remediation?

The clearance test must be ordered by someone other than the remediator — typically the property owner or buyer — and performed by a licensed Florida Mold Assessor. The assessor samples the air after remediation and compares the results to baseline outdoor spore counts. A passing clearance means indoor levels are at or below outdoor baseline for the same species. Ask for the full lab report, not just the one-page clearance certificate.

What if the seller says they do not know about any mold?

Actual knowledge is required for a Johnson v. Davis claim — a seller cannot be held liable for disclosing something they genuinely did not know. That is why buyer inspections exist. But claiming not to know becomes harder to argue when there is visible water staining in the attic, rust in the drip pan, or a remediation permit pulled on the property. Pull the permit history from the county before you close. In Florida, permits are public record.

Are there specific neighborhoods in Tampa Bay where mold risk is higher?

Waterfront and low-lying neighborhoods carry more exposure — Shore Acres, Venetian Isles, and Bayou Grande in St. Pete; canal neighborhoods in New Port Richey; low-lying sections of South Tampa near the bay. Homes in these areas flooded during Helene and some during Ian. Older concrete block homes from the 1950s–1970s in Seminole Heights, Tampa Heights, and South Tampa also warrant attention — block walls absorb moisture differently than wood frame, and remediation methods vary. That said, mold follows water, and water follows poor maintenance in any neighborhood.
