        Site Requirements

        To save you time and stress, our expert approvals teams will prepare and submit all the applications and documents required to the Private Certifier and obtain approval for your new Granny Flat.

        In 2009, the NSW government released the Affordable Housing State Environment Planning Policy (SEPP) which permits all residential home-owners with property larger than 450m² (which also has a minimum 12m street frontage) to build a granny flat on their property if their property is considered to be complying. A granny flat is a self-contained small house (with a maximum living space of 60m²) which is built in the backyard of an already existing house.

        With this change comes a new way of processing granny flat applications. Home-owners wanting to build a granny flat in their backyard are no longer required to obtain council approval as long as their application meets the minimum Complying Development requirements that have been set out.

        If your property does not meet all the conditions required to be a Complying Development, your granny flat can still be approved by lodging a Development Application (DA), which can only be approved by your local council. Once again our design consultant can take care of all this whole process for you and submit all the applications and documents on your behalf.

        Additional Granny Flat Requirements
        • Maximum of 1 granny flat is permissible per lot.
        • Maximum floor area permissible for a granny flat is 60 m².
        • Must have a 24m² courtyard space for the granny flat, with an area of at least 4m wide.
        • Conditions may apply if building in a bushfire, flood affected or heritage area.
        • For Battle-Axe blocks, an access handle of at least 3m wide is required.
        • Off-street car parking for the granny flat is not essential.

        Please Note

        This summary has been prepared as an indicative tool to help explain the site planning requirements for a Granny Flat. There are other site conditions and requirements that will effect Granny Flat appoval. A free site assessment is required in order to determine the appropriateness of a Granny Flat on your property.

        Property doesn't meet these requirements?

        Fear not! These requirements are for obtaining approval through a Complying Development
        Certificate (private certifier). If you property doesn't comply, it may still be possible to have it
        approved through a Development Application (local council).
