AddressIntel AI Briefing
Stealth density (primary + ADU + JADU) is the recommended strategy here to preserve the existing remodeled structure while adding rental income in a high-demand Sunnyvale census block. With zero hazard blockers and a clean site profile, ministerial approvals for ADU additions will be fast-tracked. A full teardown is less attractive due to tight margins and high lot coverage limits on the relatively small 5,663 sqft lot.
