Can I put a duplex on this lot?
Pulled detailsBroke down the ScoreModeled a scenario

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.

How it works

Skip the call to the city.

Three steps between wondering and knowing — no planning-department hold music.

01

Type your address

Your lot gets a 0–100 score in about 20 seconds — free, no signup, no call to the city.

02

Ask in plain English

"Can I add an ADU?" "Am I in a flood zone?" Geo runs the real scoring tools on your parcel and explains what it finds — for free.

03

Get the paper when you need it

When a contractor or lender wants documentation, export the full report as a PDF. Your first 3 are free.

What it checks

Plain English, straight from the source.

The same federal data professionals pay to have compiled — translated for the person who actually lives there.

  • Your zoning, decoded

    The designation and what it actually permits — ADU eligibility, setbacks, height — in plain English.

  • Flood, from the federal map

    Your FEMA flood zone, queried live — not a guess from a listing site.

  • Wildfire and earthquake

    Federal hazard levels for your exact location, from USGS and national wildfire data.

  • Radon and soil

    Your EPA radon zone and USDA soil suitability — the things inspectors find late.

  • Nothing invented

    Every finding cites the government dataset it came from. If a factor has no data, it drops out — it is never guessed.

FAQ

Frequently asked questions

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.
