Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~126 ft frontage × 131 ft deep — a tucked-away rear unit is very private; access is typically via the pole driveway. A second street frontage lets an ADU take its own entrance and address.
Screening heuristic based on lot size, existing coverage, lot orientation, and hazard overlays. CA ADU law is ministerial statewide; verify max size, setbacks, and JADU owner-occupancy with the local planning dept.
Redevelopment Potential
Existing home already uses most of the allowable floor area — little expansion headroom. Zoning allows roughly 3,306 sqft of gross floor area on this lot.
