DA vs CDC: What’s Right for Your Castle Cove 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 developments in E4 zones, waterfront properties, or bushfire-affected sites.

  • Needed when proposing variations to standard planning controls or larger-scale works.

CDC (Complying Development Certificate):

  • Suitable for compliant single dwellings and alterations on non-constrained land.

  • Provides a quicker approval route for straightforward builds meeting all requirements.
