An Accessory Dwelling Unit (ADU)—often called a guest house, mother-in-law suite, or backyard cottage—is one of the smartest ways to add versatile livable space to your property. Whether you want to provide independent living for aging parents, create a private space for adult children, or generate reliable rental income, a custom-built ADU unlocks your land's full potential.
