AddressIntel AI Briefing
While the massive 26,387 square foot lot suggests immense potential, the active landslide hazard zone serves as a major construction blocker that dampens teardown prospects. The most viable strategy is a stealth density play using low-impact ADU additions that avoid heavy geotechnical disruption. This pathway permits density expansion while preserving the main mid-century structure.

ADU Potential
Flag / irregular · ~195 ft frontage × 342 ft deep, a tucked-away rear unit is very private; access is typically via the pole driveway.
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
Meaningful unused floor-area headroom under current zoning, room to add square footage. Zoning allows roughly 4,500 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: Belmont Zoning Ordinance 4.2.3(d) Table 5 (Lot Size/Intensity) as a CAP on the default estimate; Table 4 slope FAR NOT applied, no per-parcel slope available (as of 2026-09-03). Verify FAR, coverage, setbacks, and height with the local planning dept.

Back-of-the-napkin deal analysis across development strategies.
We don't hold this jurisdiction's floor-area rule, so the default builds to roughly 4,500 sqft from a conservative 0.40 FAR approximation, a starting point and not a zoning answer. Check the local code before you rely on it.
Median of 6 recent single-family sales in Belmont (94002): $1,171/sqft. Sized within 25% of the 4,500 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.
