A granny flat, or secondary dwelling, is self-contained accommodation within, attached or separate to an individual home. Granny flats offer a diverse and affordable housing solution and are a popular development option.
The State Environmental Planning Policy (Housing) 2021 – also known as the Housing SEPP – facilitates development of affordable and diverse housing in the right places and for every stage of life. The Housing SEPP includes the planning provisions for:
- boarding houses
- build-to-rent housing
- seniors housing
- caravan parks and manufactured home estates
- group homes
- retention of existing affordable rental housing
- secondary dwellings (granny flats)
- social and affordable housing
- short-term rental accommodation
- design quality of residential apartment development
A council or accredited certifier can certify granny flats as complying development without the need for a development application, provided they meet specific standards in the State Environmental Planning Policy (Housing) 2021.
