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

In most cases, a Development Application (DA) is the pathway for building in Round Corner due to environmental controls and rural zoning.

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

DA (Development Application):

  • Required for most new builds and extensions in E4 and RU2 zones

  • Lodged with Hornsby Shire Council

  • Involves reports such as BAL, arborist, and wastewater when applicable

CDC (Complying Development Certificate):

  • May apply for minor changes or additions that meet strict standards and fall outside of bushfire zones

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