Often, yes. Standard homeowners policies do not cover flood damage, and about 25% of flood insurance claims come from outside high-risk flood areas. A lender usually requires flood insurance only in a FEMA high-risk zone, but Citizens Property Insurance now requires most of its residential policyholders with wind coverage to carry flood insurance regardless of zone, with all remaining policies phased in by January 1, 2027. Check the flood zone, the seller's flood disclosure and a flood quote during your inspection period.
1. What "flood zone" actually means
FEMA flood maps sort properties by risk. Zones beginning with A or V, such as AE and VE, are high-risk Special Flood Hazard Areas. Zone X is moderate or lower risk. "Not in a flood zone" usually means Zone X, not "no risk." Heavy rain, overwhelmed drainage and storm surge can reach X-zone homes, and about a quarter of flood claims come from outside high-risk areas.
See the glossary definition and the Apollo Beach flood zone guide for coastal examples.
2. When flood insurance is required
| Situation | Is flood insurance required? |
|---|---|
| Mortgage on a home in a high-risk zone (A or V) | Generally yes, for federally backed and regulated lenders |
| Mortgage on a home in Zone X | Usually not by the lender, though any lender can require it |
| Citizens policy with wind coverage, home in a high-risk zone | Yes, for renewals since July 1, 2023 |
| Citizens policy with wind coverage, any zone | Phased in by dwelling value: $600,000+ from Jan. 1, 2024; $500,000+ from Jan. 1, 2025; $400,000+ from Jan. 1, 2026; all others from Jan. 1, 2027 |
| Citizens condo unit-owner policy | No, condo unit-owner policies are exempt |
| Paying cash, private insurer | Not required, but still worth pricing |
Because many Florida buyers end up with Citizens when private coverage is hard to find, this requirement now reaches far beyond the high-risk zones.
3. The 30-day waiting period and closing
A new National Flood Insurance Program (NFIP) policy generally takes effect 30 days after you apply and pay. The main exception is a purchase: when flood coverage is bought in connection with making a loan, it can take effect at closing, as long as you apply and pay on or before closing. Private flood policies set their own rules. Either way, do not leave flood coverage to closing week.
4. The seller's flood disclosure
Florida Statute 689.302 requires sellers of residential property to give buyers a flood disclosure at or before signing the contract. It states whether the seller knows of flooding that damaged the property during their ownership, whether they filed a flood insurance claim, and whether they received federal flood assistance, such as from FEMA. Read it carefully, and ask follow-up questions if any answer is yes.
5. What to check before you close
- The flood zone on FEMA's Flood Map Service Center, plus any elevation certificate the seller has.
- The seller's flood disclosure and any claims history.
- A flood quote during your inspection period, from both the NFIP and private carriers if possible. In Zone X, it may be less than you expect.
- Your homeowners insurer's rules, especially if you will be with Citizens.
- The existing policy. An NFIP policy can sometimes be transferred from the seller, which may preserve its rating; ask your insurance agent.
Common questions
Does homeowners insurance cover flooding in Florida?
No. Standard homeowners policies do not cover flood damage. You need a separate flood policy from the NFIP or a private flood insurer.
Do I need flood insurance in Zone X?
A lender usually does not require it in Zone X, but Citizens Property Insurance requires flood coverage for most policies with wind coverage regardless of zone, phased in by January 1, 2027. About 25% of flood claims come from outside high-risk areas.
Is there a waiting period for flood insurance?
NFIP policies generally take effect 30 days after you apply and pay. Coverage bought in connection with a new mortgage can take effect at closing if you apply and pay on or before closing.
What does the Florida flood disclosure include?
Under Florida Statute 689.302, the seller states whether they know of flood damage during their ownership, whether they filed a flood insurance claim, and whether they received federal flood assistance such as from FEMA.
When does the Citizens flood requirement apply to every policy?
By January 1, 2027, all remaining Citizens personal residential policies with wind coverage must carry flood insurance, except condo unit-owner policies and policies that exclude wind.
