Hillsborough County's 1,027 Repetitive Loss Homes: A Buyer's Warning

I pulled updated NFIP data this week, and one number stopped me cold: Hillsborough County has 1,027 properties on FEMA's repetitive loss list — including 220 classified as severe repetitive loss. If you're buying, selling, or even refinancing a home anywhere from Apollo Beach to Riverview to Town 'n' Country, this is a data point that belongs in your due diligence file right now.

What "Repetitive Loss" Actually Means

FEMA's NFIP tracks what it calls "repetitive loss" properties — structures with two or more claims resulting in payments totaling more than $1,000 per claim within any 10-year period.

Severe repetitive loss properties are those that have incurred four or more claim payments exceeding $5,000 each, with a cumulative amount over $20,000 — or at least two claims with a cumulative total exceeding the value of the structure.

The critical thing buyers miss:

flood insurance premiums might spike, buyers may walk away, and lenders might hesitate — and many homeowners don't even know they're on the list until they're deep into a transaction or flood claim.

The Hillsborough Numbers Are Significant

Hillsborough County has recorded 18,549 NFIP flood insurance claims since 1978, totaling $1.2 billion in payouts.

That's not ancient history — Hurricanes Helene and Milton in 2024 drove a significant portion of the most recent claims.

Hillsborough County had 61,352 NFIP flood insurance policies written or renewed over the trailing 12 months, with an average annual premium of $1,384

— compare that to

the national average of $1,064 per year. Homes in Zone AE — the most common high-risk designation in the county — pay an average of $1,781 per year.

There are 122,158 properties in Hillsborough County that have risk of flooding over the next 30 years — representing 24.4% of all properties in the county.

That's nearly one in four homes carrying meaningful flood exposure.

What This Means for Buyers Right Now

If you're shopping in Hillsborough, here's what to ask before you make an offer:

1. Is this property on the repetitive loss list? Your agent can request this.

Owning a home in a flood-prone area can lead to rising insurance premiums, difficulty selling, and limited options — and if a home has multiple flood claims, it may be listed as a repetitive loss or severe repetitive loss property by FEMA.

2. What's the flood zone designation?

Flood zone designations beginning with "A" or "V" are identified as Special Flood Hazard Areas on the FIRM — areas defined as having a 1% or greater chance of being inundated by a flood event each year.

Zone AE homes require flood insurance if you carry a federally backed mortgage.

3. Has the evacuation zone changed?

Hillsborough County updated its hurricane evacuation zone maps for 2026 based on lessons from 2024's storm surge and inland flooding. Zone A has expanded farther inland along the coastline and Alafia River, including more areas in Apollo Beach, Town 'n' Country, and mobile home communities.

Zone E now includes some neighborhoods previously outside evacuation zones, such as parts of New Tampa, areas near Tampa Executive Airport, and inland Apollo Beach.

A home that was outside an evacuation zone a year ago may not be today.

4. Does the FEMA 50% Rule apply to this property?

If you live in a FEMA Special Flood Hazard Area in Hillsborough County, the 50% Rule requires that if repair costs exceed 50% of your home's market value, the entire structure must be repaired or rebuilt to meet current floodplain requirements.

For a flood-damaged home with deferred repairs, that threshold can hit fast.

The Discount You Might Not Know About

Here's some genuinely good news for buyers in unincorporated Hillsborough County:

Hillsborough County has been a participating community in the NFIP and CRS since 1980 and 1992, respectively, and was informed by FEMA in October 2023 that its Class 5 rating would be retained.

Class 5 communities receive a 25% discount on flood insurance premiums — roughly $5.9 million in annual savings for residents in unincorporated Hillsborough County.

On a Zone AE policy averaging $1,781 per year, a 25% CRS discount saves you roughly $445 annually. Over a 30-year mortgage, that's more than $13,000 back in your pocket. Ask your agent whether the specific property you're buying falls within unincorporated Hillsborough to confirm eligibility.

The Bottom Line for Buyers and Sellers

Repetitive loss status, flood zone designation, evacuation zone, and the FEMA 50% Rule aren't just abstract policy — they are hard dollar figures that affect your insurance cost at closing, your ability to get a mortgage, and your ability to resell the home five years from now. In a county where

flooding is the most costly and repetitive natural disaster — and where coastal tidal surge, river flooding, and inland flooding near low-lying areas are all real risks

— skipping these checks is a costly shortcut.

If you're buying anywhere in Hillsborough County and want to run a flood zone and evacuation zone check before you write an offer, check out the Hillsborough County flood zone address lookup or use the FEMA flood map search tool. And if you're weighing Hillsborough against Pinellas for your next move, the Pinellas vs. Hillsborough County comparison breaks down how flood risk, taxes, and market conditions stack up side by side.

I run these checks for every buyer I work with in the Tampa Bay area — it takes about ten minutes and can save you a genuinely unpleasant surprise at closing.
