There are a few requirements which your property needs to meet, to be permitted to do so.( this is compiled of land size / frontage and other items.) Follow our Complying Development table below as your starting point to the 10 day express approvals we offer. This means you are not subject to the long strenuous Council D.A Submissions ( up to 12 weeks) which you would undergo nominally.
The below complying development table table outlines the Minimum requirements:
Summary of Minimum Complying Development Requirements for Granny Flats - State Environmental Planning Policy (Affordable Rental Housing 2009)
