Granny flats in Campbelltown — common questions
Can I build a granny flat in Campbelltown?
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.
What is the minimum lot size for a granny flat in Campbelltown?
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.
Does flood risk affect granny flat approvals in Campbelltown?
Yes. Properties on flood control lots are ineligible for a CDC secondary dwelling, so a DA through Campbelltown City Council is then the pathway. Check flood status above before proceeding.
Do I need council approval for a granny flat in Campbelltown?
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 Campbelltown City Council may be possible, unless the zone prohibits a secondary dwelling.
How large can a granny flat be in Campbelltown?
SEPP Housing 2021 sets a maximum floor area for a secondary dwelling. The checker above reads it from the SEPP for your address.
