WHAT YOU CAN BUILD
In addition to having a separate entrance, a selfcontained granny flat must have its own bathroom, kitchen, bedroom/s, laundry area and living space. While each state has its own criteria, generally granny flats must also be:
Built on a property zoned for residential use and at least 450 square metres in size.
The only granny flat on the property.
Owned by the same person who owns the primary dwelling.
A maximum living space of around 60 square metres.
Have separate and unobstructed pedestrian access.
On the wrong property, a granny flat could cut out part of your market when you sell
