Secondary Dwellings (Granny Flats)

Granny flats, known as secondary dwellings, are a self-contained dwelling built on the same lot of land as a larger dwelling home. Granny flats can be attached, detached or separated internally from the main dwelling house.

Good building design is important to maximise the enjoyment of the dwelling and minimise the impact on neighbours.

Things to consider in design of a granny flat include use of complementary external materials, finishes and colour schemes, useable north facing living areas and private open space, cross ventilation and environmental sustainability principles required by BASIX. The requirements for building a granny flat (secondary dwelling) can be found here:

You can apply for approval by:

Development application - If your plans meet Council’s requirements under Chapter 5B – Secondary Dwellings, Citywide Development Control Plan 2013.

Complying development - If your plans meet the provisions of the Affordable Rental Housing State Environmental Planning Policy (SEPP) 2009 and the requirements of the Exempt and Complying Development Codes SEPP 2008 your proposal may be approved in 20 days by a Council accredited certifier or private accredited certifier.

A development contribution levy is a fee required to be paid for granny flat proposals. The levy will need to be paid prior to the release of either the complying development certificate or construction certificate.
