Carmichael FAQ
Can I put a tiny home in my Carmichael backyard?
Yes, if it sits on a permanent foundation, meets the 2022 California Residential Code, and complies with Sacramento County Zoning Code § 5.4.5.F as an ADU — up to 850 sq ft (one bedroom) or 1,000 sq ft (two-plus bedrooms), 4-ft minimum rear/side setbacks, 16-ft detached height limit.
Can I live in a tiny home on wheels in Carmichael?
Not as a permanent residence on a residential lot. Sacramento County classifies THOWs as recreational vehicles and Title 22 prohibits permanent RV occupancy in residential zones. Permanent residence is only allowed in a licensed RV or mobile home park.
Where do I apply for a tiny home / ADU permit in Carmichael?
Apply through Sacramento County Building Permits and Inspection Division and Planning and Environmental Review at planning.saccounty.gov. Plans must show foundation, setbacks, height, and ADU size compliance under § 5.4.5.F plus CRC habitability standards.
