Florida Flood Disclosure Requirements for Home Sellers (2026)

Florida has more FEMA-designated flood zones than any other state, and flood disclosure is the most legally consequential disclosure issue for Florida home sellers. Here's what you're required to disclose, what the penalties are for non-disclosure, and what buyers are asking about as insurance costs surge.

The Legal Standard in Florida

Florida doesn't have a single-form flood disclosure requirement like some states. Instead, the obligation comes from Florida's Johnson v. Davis (1985) standard: sellers must disclose all known facts materially affecting the value of the property that are not readily observable and not known to the buyer.

Prior flooding is unquestionably material. It affects value, insurance costs, and buyer decision-making. Failure to disclose prior flooding — even flooding that was repaired — is one of the most commonly litigated real estate disclosure issues in Florida.

HB 1097: Florida's Flood Disclosure Law (Effective 2024)

Florida's HB 1097, effective October 1, 2024, created a specific flood disclosure requirement for most Florida residential real estate transactions. Sellers are now required to disclose:

• Whether the property has flooded at any time while the seller owned it, and if so, how many times
• Whether the property has received FEMA disaster assistance related to flooding
• Whether a flood insurance claim has been paid on the property

This must be provided on a seller's written disclosure statement before or at contract execution. The buyer has the right to cancel the contract based on flood disclosure within a specified period.

The law applies to most 1–4 unit residential properties. Exceptions include new construction, certain commercial transactions, and properties being transferred between family members.

FEMA Flood Zones: What They Mean for Sellers

Check your property's FEMA flood zone designation at msc.fema.gov. Flood zones are:

• Zone X (shaded and unshaded): Moderate-to-minimal flood risk. Flood insurance not federally required but available.
• Zone AE, AH, AO, A: High flood risk. Properties with federally backed mortgages are required to carry flood insurance.
• Zone VE, V: Coastal high hazard areas. Highest-risk category; most stringent building requirements.
• Zone D: Undetermined risk.

If your property is in Zone AE, AH, AO, A, VE, or V, buyers with conventional or FHA/VA financing will be required to purchase flood insurance. In many parts of Florida (coastal areas, low-lying inland areas), flood insurance costs have risen significantly since FEMA's Risk Rating 2.0 was implemented in 2021. Properties that previously paid $800/year for flood insurance may now pay $3,000–$10,000+.

This insurance cost impact is material information even if the property has never flooded. Be prepared to discuss FEMA flood zone classification and current flood insurance rates.

CLUE Reports: What Buyers Can Access

The CLUE (Comprehensive Loss Underwriting Exchange) report shows insurance claims filed on a property in the last 7 years, including flood and water damage claims. Buyers can obtain a CLUE report on your property after you have a signed contract.

If prior water damage or flood claims appear on a CLUE report that you didn't disclose, you face significant legal exposure. Disclose proactively.

Sellers in FEMA Special Flood Hazard Areas

If your property is in a Special Flood Hazard Area (SFHA — zones A and V), additional considerations:

Elevation Certificate: An elevation certificate documents your property's elevation relative to the base flood elevation. If yours shows you're above the base flood elevation, this can dramatically reduce flood insurance costs for buyers. If you have an elevation certificate, provide it to potential buyers — it's a selling point.

FEMA's LOMA Process: If your property is incorrectly mapped in a flood zone, you may be eligible for a Letter of Map Amendment (LOMA). A surveyor can determine if your property's lowest adjacent grade is above the base flood elevation. A LOMA can remove the flood insurance requirement, dramatically reducing buyer costs.

FEMA Buyout History: Some Florida properties in repeat-flooding areas have been offered FEMA buyouts. If you've received a buyout offer and declined, or if adjacent properties have been bought out, disclose this context.

The National Flood Insurance Program (NFIP) and Private Flood Insurance

Buyers in Florida have two flood insurance options: NFIP policies (federal program, maximum $250,000 building coverage) and private flood insurance (often broader coverage, sometimes lower rates). Since Risk Rating 2.0, private flood insurance has become competitive in many areas.

If you currently have a flood insurance policy, ask your insurer about policy assignability. In some cases, NFIP policies can be assumed by buyers — which may provide cost savings if your policy predates Rate Rating 2.0 increases.

What Florida Courts Have Held on Flood Non-Disclosure

Florida courts have consistently ruled against sellers who failed to disclose flooding. Notable outcomes:

The rule: disclose all prior flooding, water intrusion, and related insurance claims, regardless of when they occurred or whether they were repaired.

Practical Checklist for Florida FSBO Sellers on Flood Disclosure

• [ ] Check FEMA flood zone at msc.fema.gov and document current zone designation
• [ ] Pull your CLUE report (as the property owner, you can request one from LexisNexis)
• [ ] Review all prior insurance claims for water, flood, and storm damage
• [ ] Locate your elevation certificate (if you have one)
• [ ] Complete written flood disclosure per HB 1097 requirements
• [ ] Order flood insurance quotes to provide to buyers (demonstrates transparency and helps buyers plan)
