AddressIntel AI Briefing
Tearing down this brand-new 2026 luxury construction is highly impractical, making stealth density: primary + ADU + JADU the only logical play to leverage the remaining lot footprint. Bypassing any environmental blockers, developers can build detached ADUs to add premium rental units in a highly desirable Mountain View pocket. The nonexistent margin between the entry price and size-matched comps means this must be treated as an asset-preservation and yield-enhancement play.

Parcel & Zoning Info
ADU Potential
Wide & shallow · Corner lot · ~97 ft frontage × 101 ft deep, limited depth, an ADU likely sits beside the house rather than behind it. 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.
Redevelopment Potential
Existing home already uses most of the allowable floor area, little expansion headroom. Zoning allows roughly 3,737 sqft of gross floor area on this lot.
Screening estimate comparing existing living area to the city's single-family floor-area limit. FAR rule curated from current municipal code. Source: Mountain View Zoning Ord. Ch. 36 (R1 Handbook) (as of 2026-06-30). Verify FAR, coverage, setbacks, and height with the local planning dept.

Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 3,737 sqft here, less than the 4,164 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 6 recent single-family sales in Mountain View (94040): $1,539/sqft. Sized within 25% of the 4,200 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.
