DA vs CDC: What’s Right for Your West Pennant Hills Project?

We assess your site conditions and project goals to determine the most efficient approval pathway.

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

DA (Development Application):

  • Ideal for custom homes, steep blocks, or where trees and overlays apply

  • Lodged through Hornsby Shire Council

  • Allows design flexibility

CDC (Complying Development Certificate):

  • Possible for simpler additions or builds that fully comply

  • Assessed by private certifier

  • Faster approvals but more restrictive

We’ll evaluate your site and guide you to the most fitting approval pathway.
