What Is an ADU (Accessory Dwelling Unit)?

An Accessory Dwelling Unit, or ADU, is a smaller, self-contained home located on the same property as your main house. It can be attached, detached, or built over an existing structure like a garage. ADUs are a smart way to:

  • Create private living space for family or caregivers
  • Generate rental income
  • Increase home value and flexibility for the future
