Flood Zones and Insurance on the First Coast: What to Check Before You Buy

The short answer

Before you're committed to a home in Northeast Florida, look up its FEMA flood zone, read the seller's flood disclosure, and get real insurance quotes for homeowners, wind and flood coverage. Do it early in your inspection period, not the week before closing.

Water is part of what makes the First Coast the First Coast. The St. Johns River, the Intracoastal Waterway, tidal creeks, marshes and the Atlantic shape where roads run and how homes are built. Knowing how water relates to a specific property is part of buying here.

How do I find a home's flood zone?

FEMA's Flood Map Service Center lets you search any address for free. You'll see a zone designation. The ones you'll run into most often here:

• Zone AE (and other A zones): a Special Flood Hazard Area, sometimes called a high-risk flood zone.
• Zone VE: a coastal high-hazard area with added risk from wave action.
• Zone X: moderate or minimal flood hazard.

If the home is in a Special Flood Hazard Area and you're using a federally backed mortgage, your lender will require flood insurance.

Zone X does not mean "never floods." Insurance professionals point out that many Florida flood claims come from outside the high-risk zones. A flood zone is a starting point, not a verdict.

What is an elevation certificate, and do I need one?

An elevation certificate is a surveyor's document showing a building's elevation compared with the expected flood level for its zone. It can make a real difference in a flood insurance quote, especially in an A or V zone.

Ask the seller whether one exists. If not, your insurance agent can tell you whether ordering one is worth it for that property.

What do Florida sellers have to disclose about flooding?

Since October 1, 2024, Florida law (Section 689.302, Florida Statutes) has required sellers of residential property to give buyers a written flood disclosure at or before the time the contract is signed. It covers flood insurance claims the seller has filed and federal flood assistance, such as FEMA aid, received for the property. The legislature expanded the disclosure in 2025.

[CONFIRM: current flood disclosure form language with title or legal counsel before publishing.]

Florida also has a long-standing duty for sellers to disclose known defects that materially affect a home's value and aren't readily observable. Read every disclosure carefully, and ask questions about anything that's unclear.

Does Citizens Property Insurance require flood coverage?

Yes, on a phased schedule that finishes soon. Under a 2022 state law, Citizens Property Insurance requires its personal residential policyholders with wind coverage to also carry flood insurance. The requirement has been phasing in by flood zone and dwelling value, and it reaches all of those Citizens policies on January 1, 2027.

A policy from the National Flood Insurance Program or a qualifying private flood policy satisfies the requirement. If you expect to insure with Citizens, build flood coverage into your budget from the start.

What inspections do insurers ask for?

Two reports come up again and again in Florida:

• Wind mitigation inspection: documents features such as roof-to-wall connections, roof covering, and opening protection like shutters or impact glass. These features can lower the wind portion of your premium.
• Four-point inspection: reviews the roof, electrical, plumbing and HVAC systems. Many insurers ask for it on older homes.

Roof age and condition carry a lot of weight with Florida insurers. Ask for the roof permit date early.

The order I recommend

1. Before you write an offer: look up the flood zone and ask whether there's an elevation certificate or a wind mitigation report.
2. Right after the contract is signed: read the flood disclosure and send the address to your insurance agent for homeowners, wind and flood quotes.
3. During the inspection period: schedule the home inspection plus wind mitigation and four-point inspections if your insurer needs them.
4. Before the inspection period ends: make sure the insurance numbers work for your budget.

One timing note: NFIP flood policies generally have a 30-day waiting period, with an exception when coverage is purchased in connection with a new loan. Don't leave flood coverage for the last minute.

Frequently asked questions

Is flood insurance required in Florida?

There's no blanket state requirement for every homeowner. Lenders require it for federally backed loans in Special Flood Hazard Areas, and Citizens requires it for its policyholders with wind coverage on the schedule above.

Does my homeowners policy cover flooding?

Standard homeowners policies generally exclude flood. Flood is a separate policy.

When is hurricane season?

The Atlantic hurricane season runs June 1 through November 30. Insurers may pause writing new policies when a storm is approaching, which is one more reason to line up coverage early.

Can I lower my premiums later?

Often, yes. Wind mitigation upgrades, an elevation certificate and higher deductibles can all change your premium. Ask your agent what applies to your home.
