Flood Risk by Address

One-screen flood-risk underwriting for any U.S. address — zone, elevation, premium, and buildability in a single report.

FEMA Flood Zone Lookup

We query the live FEMA National Flood Hazard Layer for every parcel — Zone A, AE, VE, X, X (shaded), or undetermined — with the underlying flood map panel ID so your lender, insurer, and engineer can verify in seconds.

Base Flood Elevation (BFE)

For high-risk Special Flood Hazard Areas, we surface the regulatory BFE plus the elevation differential against the parcel's USGS terrain so you know exactly how much fill, pier height, or freeboard the build requires.

Flood Insurance Cost Impact

Flood zone drives NFIP premium tier. We estimate annual flood insurance ranges per zone and structure type so monthly carrying cost is in your pro-forma from day one.

Buildability & Foundation Requirements

Special Flood Hazard Area parcels trigger elevation certificates, breakaway walls (V-zones), and elevated foundations. We flag the regulatory triggers and how they reshape budget and timeline.

Frequently Asked Questions

Where does Buildora IQ's flood data come from?
Directly from the FEMA National Flood Hazard Layer — the federal regulatory source — plus USGS elevation data for parcel-level terrain and freeboard analysis.
Is this report enough for my lender?
Our report cites the FEMA panel ID, zone, and effective date so lenders can verify the determination. It is not a substitute for a Standard Flood Hazard Determination Form (SFHDF) at closing.
Does this replace an elevation certificate?
No. An elevation certificate is a surveyor-stamped document required for NFIP rating in SFHAs. Our report is for pre-offer underwriting and feasibility — you'd commission an EC after going under contract.
How current is the FEMA data?
We query the live NFHL service, so the zone designation reflects the currently-effective FIRM panel for that parcel.
What does a report cost?
$69 Homeowner Pack, with Builder and Investor subscriptions for higher-volume workflows.
Can I run flood risk on rural / unmapped parcels?
Yes. Unmapped parcels return Zone D (undetermined) with terrain-derived flood exposure context so you still get an informed read.
