Designed for one or two persons, a granny flat is a self-contained living area usually located on the grounds of a single-family home. In the building industry, the granny flat is most often known as an accessory apartment or accessory dwelling unit (ADU).

There is no SUBDIVISION of the lot.
The granny flat must meet the planning controls set by State – for example, open space. It must also/ or meet the provisions of the ARH-SEPP.
