What is a Granny Flat According to the Sunshine Coast Council?

Under the Sunshine Coast Planning Scheme 2014, a granny flat may be referred to as a secondary dwelling (provided there is a primary residence already built and in place). A ‘Dwelling House’ is defined as being created for living purposes, this definition will also apply to a secondary dwelling. In other words, the granny flat must be used for living purposes.

What Criteria Must be Met?

There are a few points to consider. Firstly, the granny flat must be used in conjunction with and subordinate to the primary dwelling. The granny flat is designed to form part of the same household, as opposed to be used as an Air BnB for example. Ultimately meaning that the granny flat is clearly ancillary to the dwelling house.
