AddressIntel AI Briefing

An SB 9 lot split is the highest-yield strategy, utilizing the low 15% lot coverage on a massive 6,970 square foot parcel. The existing 1942 house is a textbook teardown candidate, allowing a developer to unlock multiple new single-family footprints. Liquefaction is present but mitigated by standard site engineering common to Sunnyvale.
