An isometric block of lots; one parcel is highlighted with its buildable envelope and a score of 83.
Zoning City and county code
District, permitted uses, setbacks, height, and what you can build by right.
Flood FEMA NFHL
Flood zone and special flood hazard designation, on the parcel.
Seismic USGS
Ground-shaking hazard for the site, not the county average.
Soil USDA SSURGO
Soil series, drainage, and the suitability ratings that shape a foundation.
Radon EPA
Radon potential zone, so mitigation is planned rather than discovered.
Wildfire USFS wildfire hazard
Burn probability and wildfire exposure for the parcel.
Utilities Mapped service and streets
Water, sewer, electric, and road access at the lot line.
Terrain USGS 3DEP
Slope and fall across the lot from national elevation data.
Lot shape County parcel record
Size, frontage, and the buildable envelope that results.
A factor with no data drops out of the score instead of being guessed. All data sources

A flood zone, a septic constraint, or a use restriction caps the score before anything else is averaged in.
Lender-ready PDF
A document that reads like a memo, with the source under every number.
Verifiable certificate
A QR code that recomputes the score from the record. Something a partner or a lender can check.

Is it accurate enough to act on?
Every finding is queried from its government dataset and every line names its source. A factor with no data drops out of the score instead of being estimated. Read how we measure it on the Accuracy page.
Do I need an account or a card to see the score?
No. The live Score on any U.S. address is free, with every factor cited. You only pay for the Property Report.
What do I get when I pay?
The Property Report on screen and as a PDF, the verifiable certificate, Geo for this parcel, and the report is yours to re-open and re-run for good.
I already have a consultant. Why this?
Run the report first and hand it to them. You spend their hours on judgment instead of data gathering, and you know before their memo lands whether the lot is worth it.
Where does it work?
All 50 states. Where a city publishes its code and zoning layer, the report cites it directly.
