Understanding ADUs
An Accessory Dwelling Unit (ADU), also known as an “in-law unit” or “granny flat,” is a secondary unit constructed on single-family properties. ADUs can be created by converting a garage, building a detached addition, or extending part of your existing home. ADUs typically include a kitchen, bathroom, and 1 or 2 bedrooms.
At American Dream Construction, our experienced team handles all types of ADU and home addition projects, whether you’re adding a new room or expanding your kitchen or living area. From basements to second-story additions, we are equipped to meet your needs.
