In August 2013 changes were made to how a 'granny flat' could be used. Previously they were to be used by a family member or owner, however now they can be rented to any individual.


If your property can not be subdivided or an additional grouped dwelling can not be built and your looking at increasing your income or investment return of your property, then you may wish to consider building a ' granny flat'.


To build a 'granny flat' generally your property needs to:

1. Be a minimum of 450m2

2. Have enough area for a 'granny flat'

3. Provide a pedestrian access to it

4. You may have to provide a single car bay for it depending on your properties location to transport routes

5. Have a maximum of 70m2 plot ratio (livable floor area)

6. Comply with other general requirements of the R-Codes


A 70m2 'granny flat' can be a 1, 2 or 3 bedroom unit which can attract a great rental return.
