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

Whether it’s a Development Application (DA) or a Complying Development Certificate (CDC), we’ll guide you in finding the fastest and most compliant approval pathway—anywhere in New South Wales.

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

DA (Development Application):

  • Required for duplexes, multi-dwellings, or builds near heritage and flood-affected zones.

  • Common for custom coastal homes with non-standard layouts.

CDC (Complying Development Certificate):

  • Suitable for straightforward single dwellings or extensions that meet all setback and height standards.

  • Less common near beachfront properties due to environmental overlays.
