AddressIntel AI Briefing
This fully remodeled home is a poor redevelopment target, and SB 9 is entirely blocked on this micro-lot of 1,742 sqft. The optimal play is a turnkey rental investment, capturing premium rents in a highly desirable Mountain View neighborhood. High-end school districts and excellent demographics support a stable, high-yield holding strategy.

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.

Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 784 sqft here, less than the 1,339 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 Mountain View (94040): $2,214/sqft. Sized within 25% of the 1,300 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.
