Granny flats in Sutherland Shire — common questions

Can I build a granny flat in the Sutherland Shire?

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.

Are biodiversity exclusions common in the Sutherland Shire?

Biodiversity exclusions can apply. Properties on the Biodiversity Values Map are excluded from SEPP Housing 2021 complying development for secondary dwellings. The Royal National Park and bushland corridors in Sutherland Shire can be mapped. The checker above tests the map for your address.

What lot size is needed for a granny flat in Sutherland Shire?

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 Sutherland Shire?

Heritage items and properties in heritage conservation areas are excluded from complying development. Conservation areas exist in Cronulla and parts of Engadine and Helensburgh. The checker above shows whether your address is affected.

Do I need council approval for a granny flat in Sutherland Shire?

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 Sutherland Shire Council may be possible, unless the zone prohibits a secondary dwelling.
