How to verify zoning in San Diego

San Diego layers a citywide Municipal Code over roughly fifty Community Plan areas, and the community plan is usually what sets density and height on a given parcel. 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.

Official determination: San Diego Development Services is the authority for official zoning and permit decisions; parcels in the Coastal Zone may also require California Coastal Commission review.

What decides buildability here

The factors that matter in California

A preliminary report can organize these nine factors. Available data and local depth vary by address, source, and jurisdiction.

Seismic

USGS seismic design categories drive structural cost — the same lot can pencil differently a few miles apart.

Wildfire

USFS Wildfire Hazard Potential shapes both insurability and code requirements at the urban edge.

Zoning

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 identify the sources used and the items that still require local verification.
