What Is an ADU?
An Accessory Dwelling Unit (ADU) is a self-contained living space located on the same property as your primary home.
ADUs can include:
- A full kitchen
- Bathroom
- Living space
- Private entrance
- Garage
They’re designed to function as a complete, independent residence—while still complementing your main home.
