Junior ADU (JADU) in Elk Grove
Upside ADU builds junior adu (jadu)s in Elk Grove, Sacramento County, for a $1,000 deposit with transparent fixed pricing and inspection-tied payments. A typical Elk Grove junior adu runs $44,000–$160,000 all-in, and we permit it through the City of Elk Grove Building & Planning Division end to end.
Elk Grove rules that affect a junior adu
A junior ADU stays inside your existing Elk Grove home (up to 500 sq ft) with an efficiency kitchen and its own entrance, so it skips most setback and site-work questions. Note that JADUs carry an owner-occupancy requirement, which we confirm against Sacramento County rules.
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 junior 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 junior adu (jadu) page.
