AddressIntel AI Briefing
The optimal play is to operate this nearly brand-new 2019 home as a high-performing rental or primary residence. Physical expansion, SB 9 lot splits, and ADU additions are completely blocked by the extremely high lot coverage and lack of excess land. With the property in pristine condition, there is no logical pathway for physical development or value-add remodeling.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~54 ft frontage × 58 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.
Redevelopment Potential
Existing home already uses most of the allowable floor area, little expansion headroom. Zoning allows roughly 588 sqft of gross floor area on this lot.

Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 588 sqft here, less than the 1,751 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 (94043): $1,520/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. Sized within 25% of the 1,800 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.
Interest on the purchase price for the whole project plus half the build budget, since construction draws ramp up. The default is 7% over 33 months, the median purchase-to-sale time of 239 real Peninsula and South Bay rebuilds. Set the rate to 0 for a cash purchase, or use your own lender's terms.
