Tiny home rules in Sonora, 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.
Tiny homes in Sonora are regulated based on whether they are classified as accessory dwelling units, manufactured homes, or recreational vehicles. ADU-classified tiny homes on foundations follow California ADU law. Tiny homes on wheels face more restrictions and generally cannot serve as permanent residences.
Tiny homes in Sonora are regulated differently based on classification. Tiny homes on permanent foundations may qualify as accessory dwelling units under California ADU law (Government Code 65852.2), which limits local restrictions. ADU tiny homes must meet California Building Code requirements including minimum ceiling heights, plumbing, and electrical standards. Tiny homes on wheels are classified as recreational vehicles and cannot serve as permanent dwellings under Sonora zoning. Manufactured tiny homes must meet HUD standards and be placed on approved foundations. All tiny homes require connection to Tuolumne Utilities District water and city sewer services. Sonora's small historic lots may present challenges for tiny home placement due to setback requirements.
Living in a tiny home on wheels as a permanent residence may result in zoning violations and code enforcement action. Unpermitted ADU tiny homes face standard building code violation fines and removal orders.
