Building an ADU in Carmichael under County rules
Carmichael is in unincorporated Sacramento County, so the County, not the City of Sacramento, issues the ADU permit. These points come from the County's own Shelf Ready ADU page.
Where the permit comes from
ADU building permits in unincorporated Sacramento County go through the County's Building Permits and Inspections (BPI) and are submitted online through the County's Citizen Access Portal. Setbacks for a specific parcel are confirmed with County Planning at SacPlan@SacCounty.gov. The local fire jurisdiction may require its own review, permit and fees.
Free County Shelf Ready plans
The County offers detached ADU plans free to residents of its unincorporated areas: a 460 sq ft studio or one-bedroom, an 870 sq ft two-bedroom, a 1,000 sq ft two-bedroom and a 1,184 sq ft three-bedroom. The three larger plans require a solar PV system under a separate permit. Standard building fees apply, and ADUs over 750 sq ft are subject to impact fees.
