Frequently Asked Questions about Granny Flats in Sydney

What are the advantages of Granny Flats?

These flats are smaller, more compact, more functional, and can be constructed in a fraction of the time as opposed to other building types. With it, you are building on a pre-existing plot of land. You do not need to obtain council permission once you meet the minimum requirements. All in all, this is a great investment. Another advantage is that they are versatile and close to home. If you choose to rent, you will be living next door in case something happens and can exert increased control.

You are simply converting the existing space into a more functional unit.

What building requirements in Sydney?

Once you meet the minimum requirements, you do not need council permission. The minimum requirements as per the 2009 NSW Affordable Housing State Environment Planning Policy (‘SEPP’) are:

  1. Must be a residential homeowner or property investor.
  2. The existing house must be 450 metres squared or more.
  3. Must have a minimum of 12 metre street frontage.

Your property must be in a residential area if you wish to build without council approval.

The following residential zones are approved:

  • Zone R1 - General Residential
  • Zone R2 - Low-Density Residential
  • Zone R3 - Medium-Density Residential
  • Zone R4 - High-Density Residential
  • Zone R5 - Large Lot Residential (via DA only)
