Carmichael rules that affect a junior adu

A junior ADU stays inside your existing Carmichael 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: Carmichael is unincorporated Sacramento County, so ADUs permit through the County Building Permits & Inspection Division, not a city. County setbacks run 4 ft side/rear; older detached garages near the American River often need fire-separation and egress upgrades when converted.

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.
