An Accessory Dwelling Unit (ADU) is a smaller, separate living space on the same property as a single-family home. It can be detached from the main house, such as a standalone building in the backyard, or it can be integrated into the main house, such as a basement apartment or attic conversion.

What is an ADU?

ADUs are becoming increasingly popular due to the need for additional living space and the desire for flexibility in how that space is used. Building an ADU can also be a cost-effective way to add living space, as they typically cost less per square foot than adding on to the main house.
