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. San Diego zoning is verified against the City of San Diego layer; everywhere else 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 v1.0.2, generated 2026-07-25. More neighborhoods are added as the analysis completes.
