AddressIntel AI Briefing
An SB 9 lot split is completely blocked due to severe Special Flood Hazard Area (flood_sfha) status and liquefaction. Since the 1905 structure is already fully renovated, the optimal approach is a stealth density play using ADUs, though any new footprint expansion will face strict flood elevation requirements.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~176 ft frontage × 202 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 4,509 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.
