AddressIntel AI Briefing

An active landslide hazard on this San Carlos hillside parcel poses a major blocker for any heavy construction. The optimal play is limited to a minor interior cosmetic remodel of the existing 1934 structure to avoid triggering complex geotechnical engineering reviews. Trying to push high-density development here is extremely risky.

Existing home already uses most of the allowable floor area — little expansion headroom. Zoning allows roughly 2,056 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: 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.
