Granny Flats are self-contained, small residential units typically built on the same property as a primary home. Originally designed to accommodate aging family members—hence the name "Granny Flats"—these units provide a private, independent living space while keeping loved ones close. Modern granny flats can also serve various purposes, such as guest accommodations, rental units, or home offices.
