Hillsborough Redraws Evacuation Zones: What Home Buyers Must Check Now

Earlier this hurricane season, Hillsborough County quietly dropped one of the most consequential pieces of real estate news it has published in years: the county redrew its hurricane evacuation zone maps for 2026. If you're buying, selling, or just owning a home in Hillsborough right now, there's a real chance your property sits in a different zone than it did last year — and that matters at the closing table.

Why Hillsborough Changed the Maps

Hillsborough County updated its hurricane evacuation zone maps for 2026 based on lessons from 2024's storm surge and inland flooding.

Hurricanes Helene and Milton left a mark that emergency managers couldn't ignore.

The National Oceanic and Atmospheric Administration updates its storm surge data or model every three to five years, and the new maps are created using surge data combined with county characteristics like elevation and tide levels.

As Hillsborough County's emergency management operations section chief Katja Miller explained, "Evacuation zones are very much based on storm surge, but we, of course, saw a lot of inland flooding, that riverine flooding."

The bottom line: this is not bureaucratic reshuffling. It's the county officially acknowledging that the risk picture changed after 2024.

What Exactly Changed — Neighborhood by Neighborhood

The adjustments run across all zones, but the biggest shifts affect a handful of specific areas.

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 A is the first zone ordered to evacuate when a major storm threatens — so moving into it is a meaningful shift, not a minor technicality.

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

Farther south,

Sun City Center has a zone that was previously rated Zone E upgraded to Zone D, and some zones in the Bloomingdale area moved from Zone D to Zone C.

In Thonotosassa, some areas that were not in an evacuation zone are now in evacuation Zone E.

If you own or are shopping in any of these communities, the rule is simple: look up the specific parcel, not the ZIP code.

The Flood Zone vs. Evacuation Zone Confusion — Cleared Up

I talk to buyers every week who mix these two up. They're completely different systems and both matter.

FEMA flood zones (the A, AE, VE, X designations on mortgage documents) are insurance maps.

Flood maps are a useful tool for assessing a property's flood risk and are a factor in flood insurance and building requirements. As new data and technology become available, maps are updated to show areas where the risk of flooding has changed.

If you're in a high-risk FEMA zone and you have a federally backed mortgage, flood insurance is mandatory.

Evacuation zones are a separate county system based on storm-surge modeling.

They are designated areas that may experience storm surge, flooding, or other hurricane-related impacts.

They tell you when you'll be ordered to leave, not whether your lender will require flood insurance.

A home can sit in Zone X on FEMA maps (lower insurance risk) and still be in evacuation Zone A. The reverse is also true. Before closing on any Hillsborough property, check both.

What This Means If You're Buying or Selling Right Now

For buyers, the new zones are a disclosure conversation waiting to happen. Ask the listing agent to confirm the property's current evacuation zone and pull up the county's Hurricane Evacuation Assessment Tool yourself. If the home moved from Zone B to Zone A, factor that into your insurance quotes before going under contract — not after.

For sellers in affected neighborhoods like Apollo Beach or Town 'N' Country, get ahead of the question.

Emergency management officials say "it's not something to necessarily panic about — it's just something that you need to consider within your plan."

Proactive disclosure builds trust with buyers and keeps deals from falling apart at inspection.

It's also worth noting that

both Pinellas and Pasco last updated their evacuation zones in 2022. Pasco has no current timeline for an update, and Pinellas says it's updating county building data with new zones potentially coming next year.

Hillsborough is the only tri-county market with fresh 2026 maps right now — which is both a heads-up and a competitive-intel edge for buyers comparing counties.

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

The evacuation zone redraw doesn't change that number, but it does clarify which neighborhoods are carrying more risk than the old maps showed.
