Last reviewed: October 22, 2026. Laws, tax rates and programs change — confirm details with the official sources below and your lender, title company, insurance agent or attorney. This guide is general information, not legal or tax advice.
Check the flood zone
Look up the address on FEMA’s Flood Map Service Center. Zones beginning with A or V are high-risk Special Flood Hazard Areas; X zones are moderate-to-low risk. Your agent and insurance agent can help you read the map.
When flood insurance is required
Lenders require flood insurance for homes in high-risk zones when the mortgage is federally backed or from a regulated lender. Condo associations carry building coverage, but owners may still want their own policy.
Citizens policyholders
Florida law is phasing in a requirement that Citizens Property Insurance policyholders also carry flood insurance. Check Citizens’ site for the current schedule.
Waiting periods
National Flood Insurance Program policies generally have a 30-day waiting period before coverage starts, with exceptions such as when the policy is tied to a new loan. Get quotes during your inspection period.
Seller flood disclosure
Since 2024, Florida sellers of residential property must give buyers a flood disclosure stating, among other things, whether the seller has filed flood insurance claims or received federal flood disaster assistance.
Lowering risk and cost
Elevation certificates, flood vents and other mitigation can affect premiums. The My Safe Florida Home program has offered inspections and grants for wind-mitigation improvements when funded.
Frequently asked questions
How do I find out if a house is in a flood zone?
Enter the address on FEMA’s Flood Map Service Center, and ask the seller for any elevation certificate.
Is flood damage covered by homeowners insurance?
Standard homeowners policies typically exclude flood; flood coverage is purchased separately through the NFIP or private insurers.
Do I need flood insurance in zone X?
It’s usually not required by lenders, but many South Florida owners buy it anyway because flooding can happen outside high-risk zones.
