Do you need council approval? Exempt, complying (CDC) and DA in NSW

NSWUpdated 1 July 2026

Not every project needs a full development application. NSW planning law creates three pathways, and knowing which one your project fits can save weeks. Here's the difference.

Exempt development — no approval needed

Exempt development covers minor, low-impact works — think small garden sheds, some decks, and many internal renovations. If your project meets 100% of the standards in the Codes SEPP, it needs no development consent and no formal assessment.

Miss a single standard and it's no longer exempt, so the details matter.

Complying development — fast-track CDC

Complying development is a combined planning and construction approval for straightforward projects assessed purely against coded standards. The approval — a Complying Development Certificate (CDC) — can be issued by a private certifier or council, with no neighbour-objection period and can be as quick as ~20 days.

It only works if your proposal meets every applicable standard; there's no discretion to bend the rules.

Development application (DA) — council assessment

If your project isn't exempt or complying, you lodge a DA with your council. A planning officer weighs competing considerations and can exercise judgment, and the process may include neighbour notification or public exhibition. It's more flexible but slower.

Frequently asked

What's the difference between a CDC and a DA?

A CDC is a fast-track approval checked only against fixed coded standards (no council discretion). A DA is assessed by council with judgment and may involve neighbour notification.

What can I build without any approval?

Minor, low-impact 'exempt development' — like small sheds or many internal renovations — provided it meets every standard in the Codes SEPP.

How fast is complying development?

A CDC can be issued in as little as around 20 days when the proposal meets all the coded standards.
