What Are Mother Daughter Homes?

The Core Concept

Mother daughter homes are multigenerational properties designed to house two households on one property. Features include separate living spaces such as in-law suites, duplex-style layouts, or detached accessory dwelling units (ADUs). These spaces maintain independence yet encourage family connection.
