DA vs CDC: What’s Right for Your Long Reef Beach (Collaroy) Project?

Most Long Reef Beach projects require a DA due to coastal hazard and view protection requirements, though smaller renovations may qualify for CDC. 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):

  • Often required due to coastal hazards and view impact assessments

  • Council review to ensure compliance with coastal management plans

CDC (Complying Development Certificate):

  • Possible for smaller-scale builds or alterations within planning codes

  • May not be viable for beachfront lots in hazard zones
