DA vs CDC: What’s Right for Your Schofields 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, or projects that seek variations from council standards.

  • Needed for sites with environmental or heritage considerations.

CDC (Complying Development Certificate):

  • Suitable for single dwellings, duplexes, and straightforward extensions.

  • Offers faster approval when projects meet all relevant planning standards.
