Complying Development Certificate

A Complying Development Certificate (CDC) is a combined planning and construction approval for certain developments that meet specific development standards 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.

Council's accredited certification team can issue a Complying Development Certificate and provide expert advice throughout the process.

The format, file size and documentation naming conventions used when uploading documents must meet Council's Digital Format Application Requirements.

Step 4.Lodged for review

Once the application is submitted through the Portal, an initial review will be carried out to check the information provided is sufficient for Council to accept. 

Where it is identified that further information is required before the application can be accepted, an officer will contact the applicant to request the further information or clarification. Once adequate information is provided, the application can be accepted.

Assessment of your application will not commence until the fees have been received by Council.
