Accessory Dwelling Units Portland
Understanding ADUs
An ADU (Accessory Dwelling Unit) is a secondary living space on your property, fully equipped with a kitchen, bathroom, and bedroom area.
ADUs can serve as:
-
A rental unit for additional income
-
A private guest house for family and friends
-
A home office or studio
-
Housing for aging parents or adult children
ADUs are perfect for homeowners who want to maximize their property’s potential, increase functionality, and add value—all while maintaining privacy and style.
ADU projects are ideal for properties with available space—whether in the backyard, above a garage, or as a detached unit—and require thoughtful planning and construction.
