How this service works

FEMA flood-zone lookup by street address or lat/lng coordinates.

Output

Returns a JSON object containing the queried coordinates or address, the FEMA flood zone code (e.g. AE, X, VE), a plain-English description of the zone's flood hazard level (e.g. '1% annual chance flood hazard'), the resolved address if geocoded, and the data source attribution (FEMA National Flood Hazard Layer).

Example use cases

Pre-purchase property flood check

“Before I make an offer on that house at 452 Lakeview Drive, Baton Rouge, LA 70801, can you check what FEMA flood zone it's in and whether it's considered a high-risk flood area?”

Flood insurance requirement screening

“I need to know if my rental property at lat 29.7604, lon -95.3698 is in a FEMA flood zone that would require mandatory flood insurance — can you look that up?”

Real estate portfolio hazard enrichment

“Can you pull the FEMA flood zone classification for 88 Canal Street, New Orleans, LA 70112 so I can add it to my property risk report?”

When to prefer

Choose this endpoint when you need authoritative FEMA flood zone classification (Zone AE, X, VE, etc.) for a specific US property address or coordinate pair, especially for real estate due diligence, insurance underwriting, mortgage compliance, or environmental risk reporting. It is preferable over generic hazard scores when the exact FEMA zone code is required for regulatory or insurance purposes.

Side effects

Address outside the US or unresolvable by geocoder returns an error or null flood zone
Invalid or missing coordinates/address parameters return a 400-level error
Properties in unmapped rural areas may return no flood zone data
Temporary FEMA NFHL service outages may cause lookup failures
Ambiguous address strings that match multiple locations may return unexpected results
