DA vs CDC: What’s Right for Your Mortdale Heights 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 duplexes, larger or non-standard developments, and steep/elevated sites.

  • Needed for significant alterations to existing homes.

CDC (Complying Development Certificate):

  • Suitable for simple new builds, granny flats, or extensions on compliant lots.

  • A faster approval option if meeting zoning and setback criteria.
