Granny flats in Clarence Valley — common questions

Can I build a granny flat in Clarence Valley?

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.

How does flooding affect granny flat eligibility in Clarence Valley?

The Clarence River creates flood planning areas across Grafton, Maclean, and Yamba. Properties on flood control lots are excluded from the CDC pathway and need a DA. The checker above reads the flood overlays for your address.

What lot size is needed for a granny flat in Clarence Valley?

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.

Are heritage exclusions common in Clarence Valley?

Heritage items and properties in heritage conservation areas are excluded from complying development. Conservation areas exist in Grafton and historic town centres. The checker above shows whether your address is affected.

Do I need council approval for a granny flat in Clarence Valley?

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 Clarence Valley Council may be possible, unless the zone prohibits a secondary dwelling.
