Orangevale rules that affect a attached adu
In Orangevale, 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 Sacramento County Building Permits & Inspection Division reviews it as new attached square footage.
Local permitting: Because Orangevale is unincorporated, the County Building Permits & Inspection Division reviews ADUs here rather than a city counter. The deep semi-rural lots clear the 4 ft setbacks with room to spare; the variable to watch is septic, since many parcels run on it and tank capacity shapes both siting and cost.
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.
