AddressIntel AI Briefing
With extremely low lot coverage, the optimal strategy is an SB 9 lot split into multiple units or a major stealth density expansion (primary + ADU + JADU) to exploit the massive yard space. Soil liquefaction is the primary development blocker, but the excellent price-to-ARV ratio easily justifies the cost of modern foundation engineering. The aging 1968 structure provides an ideal canvas for high-yield development.

Parcel & Zoning Info
ADU Potential
Wide & shallow · Corner lot · ~100 ft frontage × 120 ft deep, limited depth, an ADU likely sits beside the house rather than behind it. 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 3,332 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.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 3,332 sqft on this lot, and the default builds to that envelope. The FAR figure is a discretionary-review trigger, not a hard cap.
Median of 12 recent single-family sales in San Jose (95123): $751/sqft. Sized within 25% of the 3,300 sqft build, because smaller houses sell for more per foot and pricing a rebuild off them overstates resale.
Commission, transfer tax and closing. Deducted from resale before profit, so the ROI below is net of the exit rather than gross.
Carry on total capital for the project duration. At 0% the model is a cash purchase; 12 months at a typical construction-loan rate moves ROI by 6 to 10 points on a deal this size, so price it with your real rate.
