In General…

According to the Utah Residential Code, tiny homes that are on foundations are classified as permanent residences and, therefore, must follow county-specific building codes. Foundations must support and transfer all loads to the supporting soil, and the property must be graded to send surface runoff to a storm sewer conveyance. Tiny houses on wheels are widely classified as recreational vehicles (RVs), which makes using them as permanent residences more challenging. Some places charge more for tiny houses on wheels that are in permanent use. Accessory dwelling units (ADUs) and auxiliary dwelling buildings are allowed throughout the state, but not every county permits residence in ADUs. Overall, the International Residential Code (IRC) is the adopted standard for residential construction statewide in Utah.
