Hello Members I am looking at one of the highset homes(1st+2nd floor) with a granny flat underneath(See photo). The granny flat has a separate driveway and separate utility connections.The size is below 70m2 and as per the latest planning scheme released in 2015 and amendments in 2018 it seems that it can be considered as an auxiliary unit which can be rented out separately. As per the domestic housing factsheet provided by logan council. https://www.logan.qld.gov.au/downloads/file/399/fact-sheet-domestic-housing It seems that Auxiliary do not need approvals as long as they comply with the council requirements on sizing and specification. So the right way would be to ask a certifier and ensure that this particular granny flat would qualify as a Auxiliary unit and could be rented out seperately. Is my understanding correct. Thanks a ton in advance.
