AddressIntel AI Briefing
A stealth density play focusing on accessory dwelling additions is the most sensible route given the severe landslide and high fire hazard zone blockers. While the colossal 98,881 square foot lot suggests incredible scale, heavy ground-up subdivision is economically hindered by these geologic risks. Developing low-impact, fire-hardened ADUs near the existing footprint bypasses the most restrictive environmental reviews.

ADU Potential
Wide & shallow · ~320 ft frontage × 365 ft deep, limited depth, an ADU likely sits beside the house rather than behind it.
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.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Median of 12 recent single-family sales in San Jose (95120): $1,041/sqft. Sized within 25% of the 1,500 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.
