DA vs CDC: What’s Right for Your Lower Portland Project?

Due to the natural landscape and zoning, most Lower Portland developments require a DA (Development Application). CDC may apply to minor structures on select compliant blocks.

Here’s a quick breakdown to help you understand the difference:


DA (Development Application):

  • Required for most dwellings, additions, or work in flood-prone or bushfire zones

  • Lodged with Hawkesbury Council

  • Best for flexibility, rural design, or sites needing environmental reports

CDC (Complying Development Certificate):

  • Less common but may suit minor compliant works on cleared, low-risk R2 blocks

  • Faster approval via private certifier

  • Must meet strict planning and bushfire/flood control benchmarks


We’ll assess your site and goals to determine the most suitable approval path.
