Summary
Unincorporated Sutter County has no standalone 'tiny home' ordinance. A tiny home on a permanent foundation is generally treated as an ADU under Zoning Code Section 1500-10-040 (detached ADU up to 1,200 sq ft, no minimum size barrier in the code). A movable tiny home on wheels is a recreational vehicle and is not authorized as a permanent residence by the zoning code.
2. Accessory Dwelling Unit. Includes an attached or detached residential dwelling unit which provides complete independent facilities for one or more persons. It shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the existing single-family dwelling is situated. An accessory dwelling unit also includes an efficiency unit, as defined in Section 17958.1 of the Health and Safety Code and a manufactured home, as defined in Section 18007 of the Health and Safety Code.
Full Breakdown
There is no tiny-home-specific ordinance in the unincorporated Sutter County Zoning Code. How a tiny home is regulated depends on its construction. A tiny house built to building-code standards on a permanent foundation is most often permitted as an Accessory Dwelling Unit under Section 1500-10-040, which ministerially permits a detached ADU of up to 1,200 square feet by Zoning Clearance in districts allowing single-family or multifamily dwellings, with 4-foot side and rear setbacks, a height allowance of at least 16 feet, and no parking requirement.
The ADU section sets no minimum unit size in its standards, and notes lot coverage must still allow at least an 800-square-foot, 16-foot-tall ADU meeting four-foot setbacks. A small unit can also qualify as a Junior ADU (up to 500 sq ft) under Section 1500-10-050 if created within the home or an attached garage with owner occupancy and a deed restriction. A movable tiny home built on a chassis (a tiny house on wheels) is treated as a recreational vehicle or trailer and is not recognized by the zoning code as a permanent dwelling; RV occupancy is constrained by separate county standards.
Septic, well, fire, building, and floodplain requirements apply to any permanent tiny home. Confirm classification with Sutter County Development Services before building or placing a tiny home.
Violations & Fines
Placing or occupying a tiny home on wheels as a permanent residence outside an authorized RV/mobile-home context, or building a foundation-based tiny home without the required Zoning Clearance and building permit, can result in code-enforcement action and orders to remove or legalize the unit.
