Accessory Dwelling Units (ADUs), also known as secondary units, in-law suites, or granny flats, are self-contained residential units located on the same property as a primary home. These units can be attached to the main house, built as a separate structure, or converted from existing spaces like garages or basements. ADUs offer a flexible housing option for homeowners, providing additional living space for family members, rental income opportunities, or even an affordable housing solution. With rising housing costs and urban density challenges, ADUs have gained popularity as a practical, cost-effective way to maximize property use.
