Complying Development Certificate Approval

You can have a 2 bedroom Granny Flat built in your backyard, with no council approval,

without neighbours objecting and approved in just 10 -15 days?

​

In 2009, the NSW Government released the Affordable Housing State Environment Planning Policy (SEPP) which permits all residential home-owners with a property larger then 450m2 (which also has a minimum 12m street frontage) to build a Granny Flat on their property.

​

The NSW Affordable Housing State Environmental Planning Policy (SEPP) was introduced in 2009 allowing Granny Flats in NSW to be approved as a complying development in just 10 – 15 days. This legislation means that residential home owners do not require Granny Flat approvals on their property subject to some minimum requirements.

​

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 could apply for an attached granny flat.

• Maintain a 3.0m setback from the rear and 0.9m from side boundaries

• Maintain a distance of 3.0m from any existing trees that are over 4m in height

• Maximum 60m2 external area for your granny flat
