AddressIntel AI Briefing

An SB 9 lot split into multiple units represents the highest-value pathway, unlocking density in a strong Palo Alto submarket. The principal development blocker is the liquefaction zone, requiring specialized foundation engineering, but the strong demographics easily offset these costs.

Proforma ROI Calculator

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

Zoning allows roughly 2,449 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 Palo Alto (94306): $2,122/sqft. Sized within 25% of the 2,400 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.
