Complying Development Certificate

A Complying Development Certificate (CDC) is a combined planning and construction approval for certain developments that meet specific development standards. These applications are determined by Council or an accredited certifier through a fast-track assessment process.

CDCs are available for a range of development types including:

  • single and double-storey buildings
  • secondary dwellings
  • renovations to an existing house
  • swimming pools
  • retaining walls
  • fences
  • demolition of a structure/building
  • advertising signage
  • fit-out of commercial building

If your application does not satisfy all the requirements for approval as a CDC, you will need to either alter your proposal or submit a Development Application and Construction Certificate.



You must apply for a Complying Development Certificate via the NSW Planning Portal. You will need to register and log in using the link below. But first, read more about the application process below.
