DA vs CDC: What’s Right for Your Duffys Forest Project?
Due to bushfire, environmental, and zoning constraints, DA is required for most projects. Whether it’s a Development Application (DA) or a Complying Development Certificate (CDC), we’ll guide you through the process from start to finish.
Here’s a quick breakdown to help you understand the difference:
DA (Development Application):
Required for new dwellings, large-scale upgrades, and outbuildings
We manage the entire approval, including BAL reports and environmental studies
CDC (Complying Development Certificate):
Rarely available in this suburb due to zoning and overlays
