Approvals pathway

CDC or DA. This single choice drives your timeline, your cost, and your risk.

The basics — free

  • A Complying Development Certificate is issued by a registered certifier or council, typically within 20 days, with no neighbour notification and no merit assessment - but only if every standard is met.
  • A Development Application is assessed on merit by council, takes longer, and can be refused or conditioned.
  • You do not get to pick freely: if you miss one CDC standard, you are on the DA pathway.

Where this stage costs people money

Lodging a CDC application that misses a standard. It gets rejected, you've paid the certifier, and you start the DA process from scratch anyway.
