Granny Flats in New South Wales


The NSW Govt. has introduced a policy to help families by:

  1. Allowing your granny flat to be approved as complying development in 10 days.
  2. Allowing you to build a granny flat in all residential zones.
  3. Setting clear standards for the building of granny flats.

The NSW Government has made granny flats, easier and faster to build. They aim to help mums and dads create a place for those who need a space of their own, like elderly parents or children who still live at home.  These secondary dwellings also give families the chance to use a Granny Flat as a source of additional income in these challenging economic times.

The NSW Government’s affordable rental housing – state environmental planning policy (SEPP) provides a range of planning incentives to encourage home owners and developers to invest and create new affordable rental housing which will take some pressure off the public housing and health sectors. Including a granny flat can be a positive way to add value and flexibility to the use of your home.

A Granny flat is a self-contained extension of the family home that:
Is established in conjunction with a house and is either within the house, or attached to the house, or separate from the house and is on the same lot of land as the principal house and is not on a separate lot, in a strata plan or in a community title scheme.
