Granny flats in Parramatta — common questions
Can I build a granny flat in Parramatta?
It depends on the property. Under SEPP Housing 2021 a secondary dwelling needs a zone that permits it, a lot that meets the minimum size, and none of the SEPP land exclusions (such as heritage, flood, biodiversity values and some acid sulfate soil classes). The checker above tests each one for your address.
Does heritage affect granny flat eligibility in Parramatta?
Yes. Heritage items and properties in heritage conservation areas are excluded from complying development. The Parramatta CBD has a heritage conservation area. The checker above shows whether your address is affected.
What lot size is needed for a granny flat in Parramatta?
SEPP Housing 2021 sets a minimum lot size for a secondary dwelling. The checker above reads the minimum from the SEPP and compares it with the lot area for your address.
What zone do I need for a granny flat in Parramatta?
SEPP Housing 2021 lets a secondary dwelling be built only in zones where it is permitted. The checker above reads your zone and whether it permits a secondary dwelling.
Do I need a DA for a granny flat in Parramatta?
If all SEPP Housing 2021 checks pass, a CDC through a private certifier is the pathway and no council DA is needed. If any check fails, the CDC pathway is not available. A DA through the local council may be possible, unless the zone prohibits a secondary dwelling.
