AddressIntel AI Briefing
An exceptionally tiny house on a small lot makes this prime for a teardown-and-mansionize play to maximize the 40% FAR. However, if retaining the structure, a stealth density play of primary + ADU + JADU is feasible since there are no environmental hazards or blockers present on site.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~101 ft frontage × 104 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
Small, older home using a low share of the allowable building envelope on a sizable lot — a scrape-and-rebuild or major-expansion play. Zoning allows roughly 3,000 sqft of gross floor area on this lot.
