DA vs CDC: What’s Right for Your Sefton Project?

Here’s a quick breakdown to help you understand the difference:

DA (Development Application):

  • Typically required for townhouses, multi-dwelling projects, or variations from CDC controls.

  • Necessary for sites affected by heritage or environmental constraints.

CDC (Complying Development Certificate):

  • Offers a faster approval pathway for straightforward projects.
