An Accessory Dwelling Unit (ADU) is a secondary suite that is a self-contained apartment, cottage, or small residential unit, located on a property with a separate main, single-family home, duplex, or another residential unit.
The Salt Lake City Planning Division’s ADU Handbook offers a very comprehensive guide to begin the ADU planning process. This handbook provides general guidelines for property owners who want to add an ADU to a lot that already has an existing single-family home.
Questions about the ADU Handbook and other zoning questions should be directed to Salt Lake City Planning @ zoning@slcgov.com or call 801-535-7700.
