NJ Flood Zone Lookup by Address — FEMA Flood Map in Plain English

New Jersey flood zones, in plain English

A free NJ flood zone lookup by address. The zone comes from FEMA's flood map for New Jersey, checked at the exact property point — not eyeballed from a map panel. Here's what the result actually means.

What the zone letters mean

AEHigh-risk floodplain with a published base flood elevation. Insurance required on federally backed mortgages.

AHigh-risk floodplain, but no elevation study was done — no published water height.

VECoastal high-risk, with wave hazard on top of flooding. The most expensive zone to insure.

XOutside the high-risk area. Insurance optional — but about 1 in 4 flood claims come from outside high-risk zones.

DNever studied. Not a "safe" rating — an "unknown" rating.

Not mappedStill on older paper FIRM panels — when that's the case this tool says so instead of guessing.

Is this house in a flood zone?

Zones starting with A or V are the high-risk floodplain — roughly a 1-in-4 chance of flooding over a 30-year mortgage — and flood insurance is required there on federally backed loans. Zone X means the map places the property outside the high-risk area.

What is a base flood elevation (BFE)?

The height floodwater is expected to reach in the 1%-annual-chance flood. Whether your lowest floor sits above or below the BFE is the single biggest driver of a flood insurance premium.

Is this the official FEMA flood map?

The zones come from FEMA's National Flood Hazard Layer — the same data a lender's flood determination company reads. Treat a borderline result as a reason to get an Elevation Certificate, not a final answer.

Buying a house in New Jersey?

Flood damage isn't covered by homeowners insurance — it's a separate policy, and in a high-risk zone the premium is part of your real monthly cost, same as taxes. Check the zone before the offer.

Built because FEMA's site kept going down. njflood.zone runs the complete National Flood Hazard Layer for New Jersey on our own servers — every zone, floodway, and BFE in the state — so lookups work even when fema.gov doesn't. Free, from the team behind Permit & Parcel.

Common questions

NJ flood zone FAQ

How do I find the flood zone for an address in NJ?+

Type the street address into the lookup above — it reads the FEMA flood map at the property point and returns the zone, the risk level, and whether flood insurance is required.

Is flood insurance required in Zone X?+

No. Zone X is outside the high-risk area, so federally backed mortgages don't require it — but FEMA reports roughly 1 in 4 NFIP claims come from outside high-risk zones, and low-risk policies are the cheap ones.

What is the 100-year floodplain?+

The area with a 1% chance of flooding in any given year — which works out to about a 26% chance over a 30-year mortgage. That's what zones A, AE and VE mark on the New Jersey flood zone map.

Can my flood zone change?+

Yes. FEMA re-studies areas and issues new maps, and New Jersey's recent inland and coastal rule updates also affect building requirements. A house bought in Zone X can be remapped into AE.

My house has never flooded — do I still need to care?+

The zone prices your insurance and controls renovation rules in the floodplain, whether or not water has ever come in. That's why lenders check the flood zone by address on every purchase.
