AddressIntel AI Briefing
The optimal play is stealth density: primary + ADU + JADU, leveraging the strong 82/100 ADU feasibility score on this San Mateo parcel. Although SB 9 is likely, the liquefaction hazard zone and existing updated structure make a full subdivision less profitable. Adding accessory structures permits incremental density while preserving the fully remodeled existing living space.

Parcel & Zoning Info
ADU Potential
Flag / irregular · Corner lot · ~99 ft frontage × 106 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
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 2,857 sqft of gross floor area on this lot.
