AddressIntel AI Briefing
The high lot coverage of 59% and a recently renovated interior favor preserving the structure, making stealth density: primary + ADU + JADU the optimal strategy. Any extensive ground-up construction or expansion plans will face liquefaction as a geotechnical blocker, requiring specialized foundation engineering. Focus on adding accessory units under ministerial pathways to bypass complex municipal reviews.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~79 ft frontage × 102 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 2,265 sqft of gross floor area on this lot.
Screening estimate comparing existing living area to the city's single-family floor-area limit. City sets no explicit FAR (or is not individually curated); allowable area is a conservative estimate. Source: Santa Clara City Code Ch. 18.12 (R1-6L) — no FAR; 40% coverage, 25ft/2-story (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 2,265 sqft here, less than the 2,671 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 Santa Clara (95050): $1,119/sqft. Sized within 25% of the 2,700 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.
