Granny Flats rules in Parramatta

Building a granny flat in Parramatta? City of Parramatta Council applies the New South Wales planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.

Fast-track available

Often approved without a full DA

Yes. On most residential lots of 450 m² or more you can build a 60 m² secondary dwelling, often as complying development approved by a certifier in around 20 days rather than through a full development application.

Parramatta: assessed by City of Parramatta Council under the New South Wales rules below.

Approval pathway: There are two routes under the State Environmental Planning Policy (Housing) 2021: a fast Complying Development Certificate (CDC) issued by council or an accredited certifier when your lot and design meet the Codes SEPP standards, or a Development Application (DA) lodged with council if they do not.
