AddressIntel AI Briefing

The optimal play here is a stealth density: primary + ADU + JADU strategy leveraging the high 94/100 ADU feasibility score on a 6,375 sqft lot. While a ministerial SB 9 lot split is also on the table, the local liquefaction hazard zone acts as a construction blocker that will increase foundation and structural engineering costs.

Flag / irregular · Corner lot · ~125 ft frontage × 126 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.
