A granny flat is a detached living space on the property of a single-family home. It can also be referred to as an ADU, or accessory dwelling unit.


The term ‘granny flat’ comes from one of the popular uses of an ADU as a home for elderly or aging relatives. Other names for an ADU include granny unit, in-law suite, casita, garden cottage, and more.

But the ‘granny flat’ is not just limited to older relatives! This backyard space is ideal for many uses, serving as a guest house for visiting family and friends, or maybe even an at-home office for telecommuters. ADUs are versatile and designed to meet your needs.
