AddressIntel AI Briefing
The existing 4,132 sqft baseline structure represents a substantial footprint on this 10k sqft lot, meaning a complete teardown is less favorable. The optimal play is stealth density, utilizing the existing footprint to incorporate an ADU and JADU. This option allows the developer to bypass high structural demolition costs.

Parcel & Zoning Info
ADU Potential
Standard lot · Corner lot · ~79 ft frontage × 140 ft deep — typical proportions for a detached ADU behind or beside the home. 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
