Granny flats in Randwick — common questions
Can I build a granny flat in Randwick?
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.
Why are many Randwick properties ineligible for a granny flat?
A secondary dwelling can be ineligible under SEPP Housing 2021 because of the lot size, a heritage item or conservation area (including parts of Randwick, Coogee, and Kingsford), flood, or some acid sulfate soil classes. The checker above shows which applies to your address.
What lot size is needed for a granny flat in Randwick?
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.
Do acid sulfate soils affect granny flat eligibility in Randwick?
Acid sulfate soil mapping applies to parts of coastal Randwick. Some acid sulfate soil classes are excluded from SEPP Housing 2021 complying development; the class on the map decides. The checker above reads the mapping for your address.
Do I need council approval for a granny flat in Randwick?
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 Randwick City Council may be possible, unless the zone prohibits a secondary dwelling.
