Can I build a granny flat in Northern Beaches?

Can I build a granny flat on the Northern Beaches?

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 might my Northern Beaches property be ineligible?

A secondary dwelling can be ineligible under SEPP Housing 2021 because of the zone, the lot size, a heritage item or conservation area (including those in Manly, Avalon, and Palm Beach), the Biodiversity Values Map (coastal heathland and bushland), or some acid sulfate soil classes. The checker above shows which applies to your address.
