An ADU, or “accessory dwelling unit,” is a secondary housing unit located on a property zoned for single-family or multifamily residential use. These units can take various forms: detached from the main house (such as a standalone structure in the backyard), attached to the main house (like a garage conversion), or integrated within the main house (like an upstairs or basement unit). Every ADU includes a full kitchen, a bathroom, and a separate entrance.

Often referred to as “granny flats,” “in-law units,” or “backyard cottages,” ADUs have become a popular solution to housing shortages in urban areas. These compact and efficient homes offer property owners flexible ways to utilize their space. ADUs can serve as additional living quarters for multigenerational families, generate rental income, or meet other needs, such as providing a private space for guests, a home office, a studio for remote work or creative projects, or a dedicated area for hobbies. This versatility not only adds value to the property but also contributes to addressing housing challenges by expanding the community’s housing stock.
