Sydney and NSW

The NSW Government has made provisions for Granny Flats to be easier and faster to build with no council approval required*

A Granny Flat or secondary dwelling is defined as a self-contained accommodation within, attached or separate to an individual home.

In 2009 the NSW Government introduced the Affordable Housing State Environmental Planning Policy (SEPP) to help NSW families by:

  • Allowing your Granny Flat to be approved as complying development in 20 days.
  • Allowing you to build a granny flat in all residential zones*


*The minimum site requirements for a Granny Flat approval as a complying development include:

  • Property must be a minimum 450m2 in area
  • Property must be zoned residential
  • Property must have a 12-metre width at the building line of the proposed detached Granny Flat. If your property does not meet this requirement, you can apply for an attached Granny Flat.
  • Maintain a 3-metre setback from the rear and 0.9-metre from side boundaries
  • Maintain a distance of 3-metres from any existing trees that are over 4-metres in height
  • Maximum 60m2 internal area for your granny flat

The information provided is general and specific local council consultation should be arranged.
