California’s statewide ADU statutes apply on top of both, and the city’s Complete Communities and coastal overlay provisions can change the answer again near transit or the shoreline.

What decides buildability here
The factors that matter in California.
A preliminary report organizes these nine factors. Available data and local depth vary by address, source, and jurisdiction.
USGS seismic design categories drive structural cost — the same lot can pencil differently a few miles apart.
USFS Wildfire Hazard Potential shapes both insurability and code requirements at the urban edge.
Local zoning sets the envelope — height, coverage, density, setbacks — and it is where most projects are actually won or lost.
How it works
Available data, one preliminary view.
Buildability geocodes the address, queries available flood, seismic, soil, radon, wildfire, and zoning context, and runs the published Buildability Score. Reports name the sources used and the items that still need local verification.
