Planning changes announced by the NSW Government will allow small secondary dwellings such as granny flats and studios to be built in areas around Western Sydney International Airport least affected by aircraft noise.
The change will reverse the ban on secondary dwellings in key locations near the airport, boosting affordable living options in one of the country’s fastest growing regions.
“Western Sydney is at the centre of Sydney’s future growth, and the Minns Labor Government is making sure local families share in the benefits that come with it,” said Minister for Western Sydney, Prue Car.
“The new airport is creating jobs, investment and opportunity, and these changes will help more people live close to where those opportunities are emerging.”
Amendments to the Western Parkland City State Environmental Planning Policy will apply to land within the Australian Noise Exposure Concept (ANEC) 20-25 contour, which identifies areas expected to experience lower levels of aircraft noise from the new Western Sydney International Airport.
The ANEC is a long-term planning tool that forecasts aircraft noise around Western Sydney International Airport based on a range of operational scenarios, including the potential addition of a second parallel runway.
Secondary dwellings will be capped at 85 square metres and required to include aircraft noise attenuation measures such as double-glazed windows.
“Allowing small secondary dwellings in suitable areas around the new airport is a commonsense approach that will help create more affordable and flexible housing options for families, while supporting the long-term growth of Western Sydney,” said Minister for Planning and Public Spaces, Paul Scully.
“Whether it’s young people trying to stay close to home, older parents wanting to live near family, or homeowners looking for greater flexibility, these reforms will help communities grow alongside the investment coming to Western Sydney.”
The changes apply to eligible land in the local government areas of Wollondilly, Camden, Fairfield, Liverpool and Penrith.
Secondary dwellings will not be permitted in areas expected to experience higher levels of aircraft noise.
