ADUs & Home Additions in Sisters, OR

ADUs & Home Additions in Sisters, OR

Living in Sisters means wide views, quiet neighborhoods, and homes that reflect Central Oregon’s character. If you need more space, you don’t have to leave the property you love. A well-planned ADU or home addition can give you flexibility while preserving the style and setting that make Sisters unique.

An Accessory Dwelling Unit (ADU) is a secondary living space on your property. It may be a detached cottage, an attached suite, or a converted area with its own kitchen, bathroom, and entrance. A home addition expands your primary home—adding square footage for bedrooms, gathering areas, or better layout flow.
