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

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.
