AddressIntel AI Briefing

The optimal play is stealth density: primary + ADU + JADU to exploit the existing move-in ready improvements. A full teardown is financially unfeasible due to the tight ARV spread, and any secondary structures must address liquefaction soils.

Flag / irregular · Corner lot · ~76 ft frontage × 108 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.

Buildable Headroom+408 sqft

Existing home already uses most of the allowable floor area, little expansion headroom. Zoning allows roughly 2,156 sqft of gross floor area on this lot.

Proforma ROI Calculator

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

Zoning allows roughly 2,156 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 (94085): $1,143/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.
