Granny flats in Woollahra — common questions
Can I build a granny flat in Woollahra?
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 Woollahra properties ineligible for a granny flat?
A secondary dwelling can be ineligible under SEPP Housing 2021 because of the lot size, or a heritage item or conservation area (including Paddington and parts of Woollahra village). Any one exclusion blocks the CDC pathway. The checker above shows which applies to your address.
Can I build a granny flat on a Paddington terrace?
A terrace that is a heritage item, or sits in a heritage conservation area, is excluded from complying development, and a DA through Woollahra Municipal Council is then the pathway. The checker above shows whether your address is affected.
What lot size is needed for a granny flat in Woollahra?
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 I need council approval for a granny flat in Woollahra?
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 Woollahra Municipal Council may be possible, unless the zone prohibits a secondary dwelling.
