AddressIntel AI Briefing

A high asking price combined with severe landslide and moderate fire hazards makes heavy redevelopment highly risky. The optimal play is a high-end cosmetic refresh of the existing modern structure to capitalize on Belmont's strong demographics. Avoiding major excavation is critical to keeping engineering and insurance costs down.

Flag / irregular · Corner lot · ~122 ft frontage × 147 ft deepa 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 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: conservative default (0.40 FAR — city not individually curated) (as of 2026-06-30). Verify FAR, coverage, setbacks, and height with the local planning dept.
