Florida Flood Disclosure Law for Sellers: Pinellas & Hillsborough

Florida law requires sellers to disclose known flood history, flood insurance costs, and Special Flood Hazard Area (SFHA) status in writing before closing. This obligation has applied statewide since October 1, 2024, under HB 1049 — and in flood-prone counties like Pinellas and Hillsborough, it is one of the most consequential disclosures a seller will make. Getting it right protects you legally and, handled correctly, does not have to tank your price.

What Florida's Flood Disclosure Law Actually Requires

Florida HB 1049, effective October 1, 2024, created a mandatory written flood disclosure for residential real estate transactions. Before you sign a purchase contract, you must disclose in writing:

• Whether the property has experienced flood damage to your knowledge
• Whether you have received federal flood insurance payments (NFIP claims) or FEMA individual assistance related to flood damage
• Whether the property is located in a FEMA-designated Special Flood Hazard Area (SFHA) — Zones AE, VE, AH, AO, or A
• The current annual flood insurance premium if you carry a policy
• Whether the property has been subject to a FEMA flood-damage assessment or letter of map revision (LOMR)

The standard FR/Bar contract addendum now incorporates these fields. In Pinellas and Hillsborough transactions, expect your listing agent to walk you through this form as part of the pre-listing package — not at the closing table.

The key threshold: the law covers what you know. You are not required to hire a hydrologist. But "I didn't know" gets thin when the NFIP claim history is publicly accessible and Pinellas County Property Appraiser records show a permitted repair following a named storm.

How Pinellas County Exposure Differs from Hillsborough

These two counties share the same state disclosure law but carry very different flood geographies — and that changes how the disclosure lands with buyers.

Pinellas County is a peninsula surrounded on three sides by water. According to Pinellas County Emergency Management, roughly 60% of the county's land area carries some flood designation. High-risk neighborhoods include Shore Acres (33703), Venetian Isles, Riviera Bay, Coquina Key, Bayway Isles, Tierra Verde, and the entire barrier island chain from Pass-a-Grille through Clearwater Beach. A seller in Shore Acres disclosing a Helene flood event in September 2024 is giving buyers materially significant information — buyers there already price in $4,000–$12,000+ annual flood insurance premiums depending on zone and structure type.

Hillsborough County has flood exposure concentrated around the Hillsborough River corridor, the Port Tampa Bay area, coastal Apollo Beach and Ruskin, and low-lying parts of South Tampa. The county is larger and more varied — a seller in New Tampa (Zone X) has a very different disclosure profile than a seller on Davis Islands or in the Westshore area near the bay.

What "Known Flood Damage" Actually Means for Sellers

This is where sellers get into trouble — not from deliberate concealment, but from underestimating what counts as "known."

It counts if:

• You filed an NFIP or private flood insurance claim, even if the payout was small
• You received FEMA individual assistance after Helene (September 26, 2024) or Milton (October 9, 2024)
• You repaired water intrusion after a named storm, whether you filed a claim or paid out of pocket
• A prior owner disclosed flood history to you when you purchased

It arguably counts if:

• The Pinellas County Property Appraiser's damage assessment record shows a post-storm permit or damage notation on your address (courts have found constructive knowledge in similar fact patterns)
• Your HOA filed a flood claim for common areas in a condo building where you own a unit

It does not require you to:

• Research NFIP claim histories beyond your own
• Speculate about whether your property might flood in the future
• Disclose flood risk to areas of the property you have never occupied or inspected

One practical step I recommend to sellers before listing: pull your property's NFIP claim history through FEMA's Flood Insurance Rate Map (FIRM) lookup at msc.fema.gov and cross-reference with the Pinellas County Property Appraiser's permit records. It takes about 20 minutes and it tells you exactly what a buyer's attorney will find during due diligence.

How the Post-Helene Environment Changed Buyer Scrutiny

Hurricanes Helene and Milton in fall 2024 reset how seriously buyers in Pinellas and Hillsborough treat flood disclosures. Before that season, many buyers in Zone AE neighborhoods treated flood insurance as a budget line. After watching Shore Acres, Venetian Isles, and coastal Hillsborough communities sustain back-to-back storm surge events within two weeks of each other, the calculus changed.

In 2026, buyers — especially out-of-state relocators — now routinely:

• Request the seller's current flood insurance declaration page as part of the initial disclosure package
• Commission an independent elevation certificate before making an offer
• Ask whether the property has ever triggered the FEMA 50% rule (repairs or improvements totaling ≥50% of the structure's market value trigger full flood-code compliance, usually requiring elevation)
• Factor flood insurance costs into their debt-to-income ratio during pre-approval, which affects their maximum offer price

For sellers, this means a disclosed flood event with a documented, permitted repair and a current elevation certificate actually plays better than a vague "no known flooding" answer that a savvy buyer may not trust. Transparency paired with supporting documentation is the stronger listing posture. See selling a house with flood damage history for how to frame prior events with buyers.

Strategic Disclosure: Protecting Your Price While Staying Legal

Here's what I've seen work on listings where flood history exists:

1. Get an elevation certificate before you list. An elevation certificate from a licensed Florida surveyor shows exactly how your finished floor relates to the Base Flood Elevation (BFE). If your floor is 2 feet above BFE, that's a major premium reducer — and it's a concrete number you can put in the listing. A buyer seeing "Floor 2.1 ft above BFE — current NFIP premium $1,850/yr" is in a much better position than one who has to guess.

2. Attach your current flood insurance declaration page. Show the actual annual premium. If you're paying $2,200/year on a policy that's been maintained without lapse since before 2012 (a pre-FIRM building with grandfathered NFIP rates), that policy may be assumable — which is a genuine selling point. Buyers who assume a grandfathered policy avoid the full Risk Rating 2.0 repricing that a new policy would trigger.

3. Document all post-flood repairs with permits. Permitted work creates a paper trail showing the home was brought up to code. Unpermitted repairs after a storm are a red flag that buyers — and their lenders — will push back on hard.

4. Price to the actual insurance reality. If flood costs in your neighborhood genuinely run $4,000–$6,000/year, price that in. A seller who prices as if the buyer will find a $900 policy is going to face renegotiation at inspection or lose the deal at the appraisal. A local comp-based valuation accounts for the actual carrying costs buyers face in your specific micro-market.

The FEMA 50% rule guide for Tampa Bay sellers covers the separate but related issue of how improvement history can affect what a buyer can legally do with a flood-zone property after purchase.

What Happens If You Don't Disclose

Florida's Johnson v. Davis doctrine (Florida Supreme Court, 1985) requires sellers to disclose all known material facts that are not readily observable. The 2023 flood disclosure law layered explicit flood-specific requirements on top of that existing common-law obligation.

The consequences of non-disclosure include:

• Rescission of the contract — the buyer returns the home and gets their purchase price back
• Damages claims — including the cost of flood repairs the buyer incurred after closing
• Attorney's fees — Florida courts routinely award fees to prevailing buyers in real estate fraud cases
• License complaints — if your listing agent helped conceal known flooding, both agent and seller face DBPR exposure

The risk profile is especially high in Pinellas and Hillsborough right now because Helene and Milton created a documented public record of which properties flooded. FEMA assistance records are public. NFIP claim data is accessible. Buyers' attorneys know how to pull it. A seller who marked "no known flooding" on a property that appears in FEMA's individual assistance database from October 2024 has a serious problem.

The short version: disclose what you know, document what happened, and let a knowledgeable local agent help you frame it correctly for the market.
