AddressIntel AI Briefing
This property is a prime candidate for an SB 9 lot split into multiple units or a major stealth density project (primary + ADU + JADU) given the sprawling 9,148 square foot lot and low 12% coverage. Liquefaction is a noted development blocker, but the low entry price and high demand in the area easily justify the necessary geotechnical foundation upgrades. Active contractor activity in San Jose confirms a hot local development market.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~131 ft frontage × 149 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 4,117 sqft of gross floor area on this lot.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 4,117 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 (95128): $921/sqft. Sized within 50% of the 4,100 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.
Projected Profit
Warning: Margin is tight for the construction risk.
