ADU stands for Accessory Dwelling Unit and is essentially a second small dwelling on the same property as a single-family home. By definition, it’s a self-contained dwelling unit within an owner-occupied single-family residence or in a detached accessory structure located on an owner-occupied property.

Examples include an apartment over a garage, a tiny home on a foundation in the backyard, or a basement apartment (see illustrations below). These units are not bought or sold separately. These units may serve multiple purposes, such as additional income, future home for owner wanting to downsize and rent the main house or support family in need of housing.

Bountiful City allows ADUs, both internal and external units subject to meeting code requirements. Detached ADUs are considered a conditional use and require Bountiful City Administrative Committee approval. Internal ADUs are reviewed and approved by City Staff.
