AddressIntel AI Briefing
This home was built in 2026, making a teardown out of the question and leaving no room for a flip margin. With 95/100 ADU feasibility, the optimal play is stealth density via ADU addition to generate secondary rental income. This capitalizes on the strong Sunnyvale job market and high median incomes.

Parcel & Zoning Info
ADU Potential
Standard lot · Corner lot · ~76 ft frontage × 126 ft deep — typical proportions for a detached ADU behind or beside the home. 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.
Seller Motivation
Inferred from days on market and listing-description language (e.g. "as-is", "estate sale", "motivated seller"). A screening heuristic for likely negotiability, not a statement about the seller's circumstances.
Redevelopment Potential
Existing home already uses most of the allowable floor area — little expansion headroom. Zoning allows roughly 3,600 sqft of gross floor area on this lot.
