Every parcel evaluated with the same rules engine, setback inset, building footprints, CAL FIRE Fire Hazard Severity Zones, and FEMA flood data that power check.evoadu.com. Zoning is verified against the City of San Diego layer; outside the City of San Diego, eligibility is based on California state ADU law, parcel geometry, and hazard overlays without a city-specific zone code (the same way the live tool treats those addresses). Rules engine v1.0.0, generated 2026-07-05. Neighborhood statistics are informational; they are not a determination for any specific property.
