Rancho Cordova rules that affect a attached adu
In Rancho Cordova, an attached unit shares a wall and utility runs with your main home, which can cut trenching and site costs — useful on tighter lots where a fully detached build would crowd the yard. The City of Rancho Cordova Building & Safety Division reviews it as new attached square footage.
Local permitting: Rancho Cordova has its own Building & Safety Division (4 ft setbacks, 16 ft height). The split that matters: the newer Sunridge-area subdivisions like Anatolia layer HOA review on top of the city's, while Old Rancho Cordova's older, larger lots near the light-rail corridor have far fewer restrictions.
That's the attached adu-specific picture. For the full Sacramento County rulebook — every setback, height, and owner-occupancy detail — see our Sacramento-region ADU rules guide, and learn how the build type works statewide on our attached adu page.
