Not by-right — SF-3 allows a duplex on corner lots, and this one is mid-block, so two units means a conditional-use case. The by-right move here is an ADU. The land itself is clean: FEMA zone X, utilities 90/100, overall 89 (A). One thing to spec early: the soil is expansive clay, so budget the slab for shrink-swell.

Is it actually free?
Yes — the live score and Geo chat are free forever, no signup needed. Your first 3 full reports are free too, no card required.
Can it tell me if an ADU is allowed?
It shows your zoning designation and what it permits, including ADU eligibility, in plain English. Confirm with your building department before you spend money — rules change.
Where does the data come from?
5 federal agencies queried live — Census, FEMA, USGS, EPA, USDA — plus parcel and zoning partners. Every finding names its source.
Is this a permit or an approval?
No — it's a screening tool that tells you what's worth pursuing before you pay professionals. Permits still come from your city or county.
