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

Your project may be eligible for either a Development Application (DA) or a Complying Development Certificate (CDC), depending on the zoning and complexity.

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


DA (Development Application):

  • Required for duplexes, sloped blocks, or lots near constraints

  • Reviewed by The Hills Shire Council

  • More flexible, but may take longer

CDC (Complying Development Certificate):

  • Ideal for compliant builds on standard lots

  • Approved by a private certifier

  • Fast-tracked if all conditions are met


We’ll help you navigate the best approval route for your project and land.
