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

Depending on the lot type and proposal, either path may apply.

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

DA (Development Application):

  • Suitable for knockdowns, dual occupancies, and designs not fitting CDC guidelines

  • Required for sloped or bushfire-prone land

  • Lodged with Hornsby Shire Council

CDC (Complying Development Certificate):

  • Faster path for additions, garages, or compliant new builds

  • Must meet strict development controls and be outside constrained zones

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