Stealth density: primary + ADU + JADU represents the ideal pathway given the high 92/100 ADU feasibility and updated state of the structure. A complete rebuild is limited by a break-even 0.3% ROI, indicating developer capital is better spent on accessory expansions.

ADU Potential
Deep lot · Corner lot · ~57 ft frontage × 126 ft deep, room to set a detached ADU back from the street with a buffer, reads as a separate home. 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 2,744 sqft of gross floor area on this lot.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 2,744 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 Sunnyvale (94087): $1,463/sqft. Sized within 25% of the 2,700 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
