What Is an ADU?

Understanding Accessory Dwelling Units

An ADU is a secondary residential unit located on the same property as a primary home. These units can be used for:

  • Rental income

  • Guest housing

  • Multigenerational living

  • Home office or workspace

ADUs are increasingly popular across California due to their flexibility and long-term value.
