Elk Grove rules that affect a attached adu
In Elk Grove, 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 Elk Grove Building & Planning Division reviews it as new attached square footage.
Local permitting: Elk Grove's Building & Planning Division handles its own ADU review. The standout factor here is yard size — newer subdivisions have deep enough rear yards that a full 1,200 sq ft detached unit fits inside the 4 ft setbacks without crowding the main house. Height caps at 16 ft, and anything under 750 sq ft skips impact fees.
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.
