An in-law apartment is a self-contained living space within a larger residence that is typically used by family members such as grandparents, parents, or adult children. However, there are several other synonyms for this type of dwelling that may be used in different regions or circumstances. Some of these include a granny flat, mother-in-law suite, accessory dwelling unit, secondary suite, or basement apartment. Each of these terms denotes a self-contained living area that is separated from the rest of the home and typically includes its own kitchen, bathroom, and bedroom. Regardless of the term used, an in-law apartment provides a convenient and affordable housing option for many families seeking multi-generational living solutions.
