Yuba County, CA Accessory Structures: Tiny Homes (2026)

There is no reference to 'tiny homes' or 'tiny houses' anywhere in the Yuba County Development Code; movable/wheeled tiny dwellings are not a recognized housing type in the unincorporated county. The governing rules come from the camping and RV provisions. Section 11.32.070 (Campgrounds) states it is 'unlawful to place, maintain, use, or occupy any vehicle or temporary structure, such as a tent, lean-to, or other makeshift enclosure' for which no building permit has been issued 'on any lot of real property for the purpose of camping, dwelling... or establishing a temporary or permanent residency,' with an exception for property owners camping on their own real property outside the Valley Growth Boundary, 'limited to 14 days within any 60 day period.' Section 11.25.120 (Parking and Storage of Recreational Vehicles) allows an RV to be 'used for purposes of accommodating visitors, not to exceed one week within any consecutive six-month period' and requires it to be fully self-contained; RVs may not be parked or stored in a required front or street-side setback (driveways excepted). A tiny home built to code on a permanent foundation can instead qualify as an ADU under Section 11.32.030, which allows 'manufactured housing on a permanent foundation.' A wheeled tiny home used as a full-time residence is therefore not permitted as a dwelling.
