Flood zones in South Florida, explained for renters and buyers
October 28, 2026 · Zach Curtis, REALTOR®, Realty Hub
Most of coastal Broward and northeast Miami-Dade sits close to sea level, so the flood zone is one of the first things to check on any home, whether you rent or buy. Here's what the letters mean, how to look up an address in two minutes, and what it changes for your costs.
How common is it? On zach.homes on October 28, 2026, of the Hallandale Beach homes for sale we could match to FEMA's map, 662 were in a high-risk zone and 127 were not (335 more weren't matched yet). In Hollywood it was 641 in and 805 out. For Hallandale Beach rentals, 311 of 635 were mapped in a high-risk zone. Each listing on zach.homes shows its FEMA zone, from FEMA's National Flood Hazard Layer, when we can match it.
What the flood zone letters mean
| Zone | What FEMA means by it | Flood insurance with a federally backed mortgage |
|---|---|---|
| AE (and A, AH, AO) | High risk: at least a 1% chance of flooding in any year (the "100-year floodplain"). AE has a Base Flood Elevation set by detailed study. | Required |
| VE (and V) | High risk on the coast, plus storm-driven wave action. Common on the ocean side of A1A. | Required |
| X (shaded) | Moderate risk: roughly a 0.2% annual chance, or protected by levees. | Not required by law; lender may still ask |
| X (unshaded) | Minimal mapped risk. | Not required by law |
The A and V zones together are called the Special Flood Hazard Area (SFHA). FEMA points out that a 1% yearly chance works out to about a 26% chance of flooding over a 30-year mortgage (FEMA terminology). And "low risk" isn't "no risk": flood claims also come from X zones, especially after heavy rain when drainage backs up.
How to check any address
- On zach.homes: every listing page shows the FEMA flood zone when we can match it. You can also filter searches: homes for sale outside high-risk flood zones or rentals outside high-risk zones.
- FEMA Flood Map Service Center: type the address at msc.fema.gov. The official map shows the zone and, for AE/VE, the Base Flood Elevation.
- Ask for the Elevation Certificate. For a house or a ground-floor unit, it shows how high the lowest floor sits compared with the Base Flood Elevation. That matters more for the insurance price than the zone letter.
- Ask about history. Has the unit or the garage flooded? Was there a claim? Florida now makes landlords and sellers disclose this in writing (below).
If you rent
- Renters insurance doesn't cover flood. Florida's required rental disclosure says so in its first line. A separate contents-only flood policy (through the National Flood Insurance Program or a private insurer) covers your belongings.
- The flood disclosure: since October 1, 2025, a landlord must give you a separate flood disclosure at or before signing any lease of one year or longer. It says whether the landlord knows of flooding that damaged the unit, filed a flood claim, or received flood aid such as FEMA assistance. If the landlord doesn't provide it and a flood later destroys half or more of the value of your belongings, you can end the lease with written notice within 30 days (Florida Statutes §83.512).
- Practical checks: where your car parks (ground-level garages flood first), which floor you're on, and whether the building has flood barriers or pumps.
If you buy
- Lenders require flood insurance on homes in A and V zones when the loan is federally backed or from a federally regulated lender, which is most mortgages.
- The 30-day wait: a new National Flood Insurance Program policy usually takes effect 30 days after you apply and pay. The big exception: when you buy it in connection with a new mortgage, coverage can start at closing (44 CFR 61.11). Don't wait until a storm is in the forecast.
- Condos: the association usually insures the building, sometimes including a master flood policy. Your unit policy (HO-6) covers your interior and belongings, and your lender may require separate flood coverage for the unit. Ask for the association's flood policy and its coverage amount.
- Seller disclosure: Florida requires sellers of residential property to disclose known flooding, flood insurance claims and flood aid in writing (§689.302, expanded October 1, 2025). Read it before your inspection period ends.
- Get a quote before you offer. Flood premiums depend on the building's elevation, construction and distance to water, not just the zone letter. On a house, a quote can change your monthly budget a lot. zach.homes shows the flood zone and a property insurance estimate on each listing's full-cost section; your insurance agent gives the real number.
Does a flood zone mean don't buy or rent?
No. Much of the coast is in a high-risk zone, including many buildings people love living in. It means: budget for flood insurance, check the elevation and history, and look at how the building is built and maintained. Higher floors in a concrete condo tower are a different risk than a ground-floor unit or a single-story house near a canal. Use the payment calculator with an insurance quote to see the real monthly cost.

Questions
What is the difference between flood zone AE and X?
AE is FEMA's high-risk zone, with at least a 1% chance of flooding each year and a set Base Flood Elevation; flood insurance is required for most mortgages there. X is moderate or minimal risk, and flood insurance is not required by law, though floods still happen there.
How do I check the flood zone of an address in Florida?
Look it up on FEMA's Flood Map Service Center at msc.fema.gov, or check the listing on zach.homes, which shows the FEMA zone from the National Flood Hazard Layer when it can be matched. For a precise picture, ask for the Elevation Certificate.
Do renters need flood insurance in Florida?
It isn't required, but renters insurance does not cover flood damage. A separate contents-only flood policy protects your belongings.
Is there a waiting period for flood insurance?
Usually 30 days for a new National Flood Insurance Program policy. If you buy it in connection with a new mortgage, coverage can start at closing.
Do Florida landlords have to disclose flooding?
Yes, for leases of one year or longer signed since October 1, 2025: a separate flood disclosure about known flooding, flood claims and flood aid (Florida Statutes 83.512).
