Flood Zone Lookup by Address for Miami-Dade and Broward
Updated September 2026
Type any Florida address and read its designation on the official FEMA flood map. In South Florida the zone decides whether flood insurance is required, roughly what it will cost, and what a lender will ask for before closing. Check it before you tour, not after you fall in love.
Is it in a flood zone?
In Florida, flood zone drives insurance cost and lender requirements. Check any address against the official FEMA flood map.
Source: FEMA National Flood Hazard Layer. An estimate, not an official determination — confirm with your lender and insurer.
What the letters mean, and what to do with them
Enter the full street address with city and ZIP. The tool geocodes it and reads the FEMA National Flood Hazard Layer at that point, then returns the mapped zone with a plain-language reading of what it means for insurance and financing.
Zones that begin with A or V are Special Flood Hazard Areas: the one-percent annual-chance floodplain. Flood insurance is mandatory there with a federally backed mortgage, and V zones, which add wave action, sit in the highest premium tier. Shaded X is the moderate, 0.2-percent area, where coverage is usually optional and far cheaper. Plain X is minimal risk. D means FEMA has not analyzed the area.
The zone is the starting point, not the number. In a high-risk zone an elevation certificate can move the premium significantly, so ask the seller whether one exists and order one during the inspection period if it does not. Then get a written flood quote before you waive contingencies.
This is an estimate from a public dataset, not an official determination. Lenders use their own flood-determination service, and insurers rate on more than the zone. Confirm with both before you rely on the result, or call us and we will pull it with you.
FEMA flood zone codes: what each one means for a Miami-Dade buyer
| Zone | Meaning | Flood insurance |
|---|---|---|
| X (unshaded) | Minimal hazard — outside the 0.2% annual-chance floodplain | Optional with most lenders; cheapest premiums |
| X (shaded) / B | Moderate hazard — 0.2% annual-chance (500-year) floodplain | Optional; often recommended |
| AE / A | Special Flood Hazard Area — 1% annual-chance flood, base flood elevation set (AE) or not (A) | Required with a federally backed mortgage |
| AH / AO | Special Flood Hazard Area — shallow ponding or sheet flow, 1–3 ft | Required with a federally backed mortgage |
| VE / V | Coastal high hazard — 1% flood plus wave action | Required; highest premiums; elevation certificate essential |
| D | Undetermined risk | Lender decides |

“SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year.”
Questions about flood zones
Does a flood zone mean the home has flooded?
No. A zone describes modeled risk, not history. Ask the seller for the disclosure of prior flooding and insurance claims, and check the elevation of the structure relative to the base flood elevation.
Can I avoid flood insurance in an A or V zone?
Not with a federally backed mortgage: the lender must require it. Cash buyers can decline, though we rarely recommend it in a Special Flood Hazard Area.
Why is the zone different from a neighbor’s?
Flood maps follow elevation contours and drainage, not streets. Two homes on the same block can sit in different zones, which is why we check the exact address rather than the neighborhood.
Where does the data come from?
The FEMA National Flood Hazard Layer, queried live for the geocoded point. FEMA revises maps over time, so the result reflects the current effective map, not a future one.
What flood zone is Miami in?
All of them. Miami-Dade has X, AE, AH, AO and VE zones, often within a few blocks of each other, because the maps follow elevation and drainage rather than streets. That is why the lookup asks for the exact address, not the city.

Send us the address. We will confirm the zone, ask about the elevation certificate, and point you to an insurance quote before you write an offer.
