AddressIntel AI Briefing
While the low lot coverage and massive 10,922 square foot lot suggest strong teardown-and-mansionize potential, the active landslide zone blocker severely limits site construction. A stealth density approach of primary + ADU + JADU remains the optimal, albeit cautious, path to add square footage within legal parameters.

Parcel & Zoning Info
ADU Potential
Flag / irregular · ~141 ft frontage × 153 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
Small, older home using a low share of the allowable building envelope on a sizable lot — a scrape-and-rebuild or major-expansion play. Zoning allows roughly 3,984 sqft of gross floor area on this lot.
Screening estimate comparing existing living area to the city's single-family floor-area limit. FAR figure is a discretionary-review trigger, not a hard cap — treat as approximate. Source: San Mateo Muni Code 27.18.060 (R1-B/C); 6,000 sqft cap (as of 2026-06-30). Verify FAR, coverage, setbacks, and height with the local planning dept.
