DA vs CDC: What’s Right for Your Sun Valley 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 multi-dwelling developments, extensions, or projects on bushfire-prone land.

  • Necessary for sites with environmental overlays or design variations.

CDC (Complying Development Certificate):

  • Suitable for single dwellings, duplexes, and extensions that meet council and state standards.

  • Offers a faster approval process for compliant projects.
