If you’re planning a new home, granny flat, renovation, extension, or other development project in New South Wales, you’ve likely come across the terms CDC and DA.
Understanding the difference between a Complying Development Certificate (CDC) and a Development Application (DA) is important, as choosing the right approval pathway can save significant time and help your project move forward more efficiently.
What Is a CDC?
A Complying Development Certificate (CDC) is a fast-tracked approval pathway available for certain types of development that meet specific planning and development standards.
Rather than requiring approval from your local council, a CDC can be issued by an accredited private certifier when the proposed development satisfies all applicable requirements.
Common projects that may qualify for a CDC include:
- New homes
- Granny flats
- Home extensions
- Garages and sheds
- Swimming pools
- Certain commercial developments
The main benefit of a CDC is speed. In many cases, approval can be obtained much faster than through a traditional Development Application process.
What Is a DA?
A Development Application (DA) is submitted to your local council for assessment when a project does not qualify for a CDC or requires a more detailed planning review.
Council assesses the proposal against local planning controls, zoning requirements, environmental considerations, and community impacts before determining whether approval should be granted.
Projects that often require a DA include:
- Developments that do not meet CDC standards
- Complex residential developments
- Certain commercial and industrial projects
- Developments in environmentally sensitive areas
- Heritage-listed properties
Because council assessment is required, DA approval timeframes are generally longer than CDC approvals.
Which Option Is Better?
Neither pathway is necessarily better than the other. The appropriate approval process depends on the nature of your project and whether it meets the requirements for complying development.
Where a project qualifies for a CDC, many property owners choose this pathway due to the streamlined approval process and reduced timeframes.
However, if a project does not meet CDC requirements, a DA may be the only available option.
How Do I Know If My Project Qualifies?
Determining whether a project qualifies for a CDC can be challenging, particularly when planning controls, zoning requirements, site constraints, and development standards need to be considered.
A Preliminary CDC Assessment can help identify whether your proposed development is eligible before significant time and money are invested in design and approvals.
