The State Government has changed planning laws to allow bigger granny flats which will improve their accessibility and create more housing options for South Australians.

The State Government has increased the maximum floor area in granny flats from 60 to 70 square metres, to make these units a realistic housing option for people to age in place, or young adults leaving home.   

The 10 square metre increase will make granny flats more accessible and improve the amenity for the occupants.

The changes were implemented as a result of feedback from the public and local councils during community consultation for the Ancillary Accommodation and Student Accommodation Definitions Review Code Amendment.

The adopted Code Amendment also allows councils to approve self-contained accommodation, with the Government changing technical definitions which has resulted in planning approvals previously being denied.

The changes to the Code mean granny flats will no longer have to share kitchens, bathrooms or laundries with the house, while student accommodation can include individual facilities to be self-contained.

These important technical changes allow for greater housing diversity across the state and will support South Australians to age in place, ultimately improving affordability.
