What your lot’s records say.

The four things that decide what you can build, in plain English.

  • Your zoning, decodedYour zoning district, and where we’ve read your city’s code, what it allows: units, height and setbacks.
  • Flood, from the federal mapYour zone from FEMA’s National Flood Hazard Layer. Not a listing site’s guess.
  • The ground under itSlope from USGS elevation and soil suitability from USDA: what drives foundation cost.
  • Wildfire and radonWildfire hazard from the Forest Service, and your county’s EPA radon zone.

No data, and the factor drops out; regional estimates are labeled.

Before you start.

Is it actually free?

Yes. The live Score and Geo chat are free. The full report is $99, one time, and never expires.

Can it tell me if an ADU is allowed?

It shows your zoning district, and where we’ve read your city’s code, whether an ADU is allowed and how big. Confirm with your building department before you spend money.

Is this a permit or an approval?

No. It tells you what is worth pursuing before you pay professionals. Permits still come from your city or county.
