AddressIntel AI Briefing
The optimal play is stealth density: primary + ADU + JADU, utilizing the existing nearly new 2021 build as a premium primary residence. High local census block demographics with a $247,917 median income support a strong ARV ceiling, but the property's steep purchase price completely blocks any logical teardown-and-mansionize or SB 9 lot split strategy.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~69 ft frontage × 98 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
Existing home already uses most of the allowable floor area, little expansion headroom. Zoning allows roughly 1,568 sqft of gross floor area on this lot.

Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 1,568 sqft here, less than the 2,265 sqft standing today, so a compliant rebuild would be smaller than the existing house. We don't quote a return on this one. Demolishing generally forfeits the existing non-conforming floor area, so treat it as a remodel or check the local code for what it lets you rebuild.
Median of 12 recent single-family sales in Sunnyvale (94086): $1,345/sqft. Sized within 25% of the 2,300 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.
