AddressIntel AI Briefing

Negative ground-up development ROI suggests that stealth density: primary + ADU + JADU is the optimal play to add rental income without incurring the capital losses of a total demolition. This maintains the current 3,360 sqft footprint in a prestigious, high-income Los Altos neighborhood.

Proforma ROI Calculator

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

Zoning allows roughly 3,811 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 Los Altos (94024): $1,684/sqft. Sized within 25% of the 3,800 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.
