AddressIntel AI Briefing
With low lot coverage and an attractive price-to-ARV spread, the optimal play is stealth density: primary + ADU + JADU. While an SB 9 lot split is technically feasible, the liquefaction zone hazard acts as a potential blocker that increases foundation and seismic engineering costs for a multi-unit subdivision.

ADU Potential
Flag / irregular · ~101 ft frontage × 119 ft deep, a tucked-away rear unit is very private; access is typically via the pole driveway.
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 3,019 sqft of gross floor area on this lot.
