DA vs CDC: What’s Right for Your Toongabbie 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 housing, townhouses, and heritage sites.

  • Needed if seeking variations from standard setback or lot controls.

CDC (Complying Development Certificate):

  • Suitable for straightforward projects such as single homes, compliant duplexes, and extensions.

  • Provides faster approvals if all standards are met.
