DA vs CDC: What’s Right for Your North St Marys 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):

  • Necessary for multi-dwelling developments or non-compliant designs.

  • Required for sites affected by flooding or environmental overlays.

CDC (Complying Development Certificate):

  • Suitable for new single homes, duplexes, and extensions that fully comply with zoning rules.

  • Provides faster approval for straightforward, compliant projects.
