Upside ADU builds junior adu (jadu)s in Sacramento, Sacramento County, for a $1,000 deposit with transparent fixed pricing and inspection-tied payments. A typical Sacramento junior adu runs $44,000–$160,000 all-in, and we permit it through the City of Sacramento Community Development Department end to end.

Sacramento rules that affect a junior adu
A junior ADU stays inside your existing Sacramento 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: Within City of Sacramento limits, detached ADUs follow a 4 ft side/rear setback, a 16 ft height limit (taller near transit), and require no replacement parking. The city's pre-approved ADU plan set and ADU Resource Center can drop plan check to roughly 30 days, and units under 750 sq ft are exempt from 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.
