The simplest way to build a granny flat (up to 60m2) is through the Affordable Housing Scheme.  Your plans can be approved by a Private Certifier within 14 days as a Complying Development, without the need to go through the Council’s DA process.

Your property needs to meet the following criteria to be able to achieve approval through the Affordable Housing scheme for a detached granny flat.   If it doesn’t meet these criteria, you may still be able to build an attached granny flat or you may be able to have your plans approved through the Council DA process.
