DA vs CDC: What’s Right for Your Bonnet Bay 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):

  • Commonly required for sloping blocks and bushfire-prone sites.

  • Needed for duplexes, multi-dwellings, or projects outside CDC standards.

CDC (Complying Development Certificate):

  • Suitable for straightforward single homes and extensions that meet all controls.

  • Less common in bushfire-affected areas where DA assessment is usually necessary.
