AddressIntel AI Briefing

An SB 9 lot split into multiple luxury units is the optimal choice for this 135-year-old historical-age asset. The lack of hazard zones simplifies the build process, and elite demographics provide a highly lucrative exit. Moderate lot coverage makes an ADU/JADU stealth density strategy a strong alternative path.
