AddressIntel AI Briefing
This move-in-ready home sits on a compact lot and is severely constrained by liquefaction hazards, which dramatically elevate foundation engineering costs. These factors kill any complex SB 9 split, leaving a high-efficiency ADU or JADU addition as the best path to capture rental yield without triggering costly soil remediation.

ADU Potential
Deep lot · Corner lot · ~52 ft frontage × 116 ft deep — room to set a detached ADU back from the street with a buffer — reads as a separate 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
Meaningful unused floor-area headroom under current zoning — room to add square footage. Zoning allows roughly 2,352 sqft of gross floor area on this lot.
Screening estimate comparing existing living area to the city's single-family floor-area limit. FAR figure is a discretionary-review trigger, not a hard cap — treat as approximate. Source: SJMC 20.30.200; 20.100.1020 (Single-Family House Permit) (as of 2026-06-30). Verify FAR, coverage, setbacks, and height with the local planning dept.
