AddressIntel AI Briefing
The optimal play is a luxury teardown-and-mansionize build to capture the high-end Saratoga market, or alternatively an SB 9 lot split to exploit the massive parcel size. However, developers must navigate critical blockers including high fire and landslide hazard zones, which will significantly elevate construction, engineering, and insurance costs.

ADU Potential
Flag / irregular · ~241 ft frontage × 286 ft deep, a tucked-away rear unit is very private; access is typically via the pole driveway.
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 4,400 sqft of gross floor area on this lot.
Screening estimate comparing existing living area to the city's single-family floor-area limit. FAR figure is a discretionary-review trigger, not a hard cap. Treat as approximate. Source: Saratoga City Code 15-45.030 (R-1-10,000 default; district unresolved) (as of 2026-08-24). Verify FAR, coverage, setbacks, and height with the local planning dept.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 4,400 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 Saratoga (95070): $1,506/sqft. Sized within 25% of the 4,400 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
