Generally the reason why a granny flat is considered in the first place is because there is a need to house relatives of the family such as the name implies, the grandmother or grandfather.
When considering your options to build a granny flat on your property be sure to check with your local Council with regards to their specific regulations. Each Council applies different regulations.
The following general regulations govern granny flats across most local councils:
Unlike NSW where legislation has changed to make construction and the use of a granny flat accessible to almost everyone, building a granny flat in Brisbane is different for each Council.
Generally, a granny flat is defined as a ‘secondary dwelling’ or supported accommodation. This means granny flats are secondary to the main property on a single block, they are self-contained with their own entrance as well as a separate bathroom, kitchen, bedroom, laundry and living area.
Similarly, the downstairs of a two storey house can be considered a granny flat because generally it will have the criteria to fit a granny flat.
In Brisbane, it is not possible to rent or lease a granny flat that is under the house as can be found in “Acceptable Solution A8” in the House Code.
A house is required to be occupied by a single household group and so if the downstairs area was rented or leased to someone different to living in the top section of the house, this would be termed as a secondary residence and as such would be in direct violation of the “Acceptable Solution A8” because there are 2 families occupying the one house.
Failure to comply with the “Acceptable Solution A8” will result in a formal notice of warning from the residential authorities and/or Brisbane City Council.
