AddressIntel AI Briefing

The optimal play is a teardown-and-mansionize development to exploit the massive 84,071 sqft lot and $56.6M size-matched net ARV. However, the landslide hazard zone serves as a serious environmental blocker requiring intensive geotechnical engineering. Excellent demographics, including a $250k+ median income, support an ultra-high pricing ceiling.

Flag / irregular · Corner lot · ~416 ft frontage × 665 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+9,338 sqft

Small, older home using a low share of the allowable building envelope on a sizable lot, a scrape-and-rebuild or major-expansion play. Zoning allows roughly 11,580 sqft of gross floor area on this lot.

Screening estimate comparing existing living area to the city's single-family floor-area limit. City sets no explicit FAR (or is not individually curated); allowable area is a conservative estimate.

Proforma ROI Calculator

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

Median of 12 recent single-family sales in Los Altos Hills (94022): $1,580/sqft. Sized within 25% of the 3,400 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.
