What’s My Base Flood Elevation? – Check By Address

The base flood elevation is the height, in feet above a vertical datum, that floodwater is expected to reach during the base flood — the flood with a 1% chance of happening in any year (the “100-year flood”). FEMA publishes a BFE for high-risk AE and VE zones. Your home’s height relative to the BFE is the single biggest driver of its flood-insurance rating.

Enter your address above. We check it against FEMA’s National Flood Hazard Layer — the official flood maps — to show your flood zone free, then your FIRM panel and effective date — plus your Base Flood Elevation where FEMA publishes one — in the full report. Doing it yourself means reading the FIRM panel on FEMA’s Map Service Center by hand.

The flood zone (AE, VE, X, etc.) tells you the category of risk — whether your address is in a high-risk Special Flood Hazard Area. The BFE is a specific number: how high the base flood is expected to rise there. High-risk AE and VE zones carry a BFE; low-risk zones like X do not.

Flood-insurance pricing depends heavily on how many feet your home’s lowest floor sits above or below the BFE. A home built above its BFE typically pays far less than one below it, and lenders in high-risk zones require flood insurance on federally backed mortgages. The BFE is the reference line an elevation certificate measures against.

An elevation certificate is a document prepared by a licensed surveyor that records your home’s actual elevation relative to the BFE. Insurers use it to rate a policy precisely. This tool gives you the BFE to compare against; the surveyed elevation of your home comes from the certificate itself.

No. This is a free lookup against FEMA’s public National Flood Hazard Layer — a fast, accurate starting point, but not an official flood determination, Letter of Map Amendment, or surveyed elevation certificate. Because zone lines can cross a single parcel, confirm the details that set your insurance premium with FEMA or your insurer.

Yes. The flood zone lookup is completely free — no credit card and no hidden fees. Enter your email to also get your FIRM panel, your Base Flood Elevation where FEMA publishes one (high-risk SFHA zones), and a full property risk report (flood, storm, roof, and radon) at no cost; a deeper paid report is offered but never required. Note that FEMA does not publish a BFE for most low- and moderate-risk zones (like Zone X) — if your address is in one, no BFE exists for it and none is required.

Enter any US property address in the form above — no signup or account required. The tool checks FEMA’s flood maps, shows your flood zone free, and gives your FIRM panel, your BFE where FEMA publishes one, and full property risk on the next screen. Results appear in seconds.
