AddressIntel AI Briefing

Built in 2016 with high lot coverage, this modern home has virtually no development potential as SB 9 is blocked and ADU feasibility is very low. High acquisition costs relative to ARV further eliminate any margin for development.

Existing Coverage100.6%

Wide & shallow · Corner lot · ~62 ft frontage × 64 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.

Proforma ROI Calculator

Back-of-the-napkin deal analysis across development strategies.

Zoning allows roughly 2,191 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 (94086): $1,334/sqft. Sized within 25% of the 2,200 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.
