What Is an Accessory Dwelling Unit (ADU)?
An ADU—also known as a granny flat, in-law unit, or secondary home—is a fully functional living space built on your existing property. ADUs typically include a kitchen, bathroom, and bedroom and are a smart way to increase your property’s versatility and value.
