Tiny home rules in McClellan Park, CA — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
McClellan Park is an unincorporated CDP in Sacramento County built around the former McClellan Air Force Base. Tiny home rules follow the Sacramento County Zoning Code (Title 5) and the 2022 California Building Code, not a separate city ordinance. Permanent-foundation tiny homes can qualify as ADUs under Zoning Code § 5.4.5.F. Tiny homes on wheels are classified as recreational vehicles and may not be occupied as permanent residences outside a licensed RV or mobile home park.
Much of McClellan Park is zoned for industrial, airport, and business-park use as part of the McClellan Park Master Plan/Specific Plan area, with residential use limited to specific subareas. Within parcels that allow a primary single-family dwelling, an ADU is permitted under Sacramento County Zoning Code § 5.4.5.F: detached ADUs up to 850 sq ft (one bedroom) or 1,000 sq ft (two-plus bedrooms), 4-ft minimum setbacks from interior side and rear property lines, and a 16-ft height limit (25 ft if attached to the primary home). Sacramento County has not adopted a stand-alone tiny-home-on-wheels ordinance; movable tiny units must be installed on a permanent foundation and meet the California Residential Code, including 120 sq ft minimum habitable room area (CRC R304) and 220 sq ft for an efficiency unit. Property owners must verify zoning of the specific parcel through Sacramento County Planning before assuming residential ADU rights apply.
Placing a tiny home on a parcel zoned business-park, industrial, or airport without proper residential entitlement violates the McClellan Park Specific Plan and Sacramento County Zoning Code, exposing the owner to code-enforcement citations, daily fines, and a requirement to remove the structure or vacate. Building without permits triggers stop-work orders and after-the-fact permit costs.
