Given the extreme age and small footprint of the existing house, the optimal play is stealth density: primary + ADU + JADU using the AB 1033 condo conversion pathway. Soil liquefaction is a potential structural blocker that will require specialized foundation engineering during construction.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~105 ft frontage × 141 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
Meaningful unused floor-area headroom under current zoning, room to add square footage. Zoning allows roughly 1,764 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.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 1,764 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 (95112): $678/sqft. Sized within 25% of the 1,800 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.
