One of the first questions many property owners ask when planning a development is whether they should pursue a Development Application (DA) or a Complying Development Certificate (CDC). While both pathways can ultimately achieve the same outcome, understanding the differences early can save significant time, money and frustration throughout the project.

A CDC is often viewed as the faster and more streamlined approval pathway. Where a proposal complies with all CDC controls, a CDC can effectively combine planning approval and construction approval into a single process. This often results in shorter approval timeframes, reduced consultant costs and the ability to commence construction sooner than through the traditional DA pathway.

However, a CDC is not available for every development or every site. In addition to complying with the prescribed development standards, a property must also be eligible for the CDC pathway. Site-specific constraints such as heritage listings, heritage conservation areas, bushfire-prone land, flooding, coastal hazards, environmental sensitivities, contamination and other planning controls may limit or completely exclude the ability to obtain a CDC. Before investing in detailed design work, it is important to understand whether the site itself is suitable for this approval pathway.

Even where a site is eligible, the proposed development must also satisfy the CDC design criteria relating to building setbacks, height, site coverage, landscaping, private open space and numerous other requirements. If a proposal does not meet even one of the prescribed standards, and the applicant is unwilling or unable to amend the design, then the CDC pathway is no longer available and a DA will be required.

This is where early planning advice becomes invaluable. Too often, applicants invest considerable time and money designing a project before determining whether it can actually proceed as a CDC. Investing in a planning feasibly report tailored to your site to determine which approval pathway is likely to be the most suitable is recommended before significant design costs are incurred.

The reality is that choosing between a DA and a CDC is not always about obtaining the quickest approval. It is about determining what is most important to the overall success of the project. Outlining the desired development outcomes early can help establish whether time, cost or design flexibility should drive decision-making. For some developments, minimising approval timeframes and reducing upfront costs may be the primary objective, making a CDC the preferred pathway. For others, achieving a specific design outcome for a ‘dream home’ may be far more important than the additional time and cost involved in obtaining a DA and subsequent Construction Certificate (CC).

Neither pathway is inherently better than the other. A CDC can be an excellent option where the development comfortably meets the requirements and speed is a priority. A DA, on the other hand, provides greater flexibility and allows Council to assess proposals on their merits, including developments that may not strictly comply with DCP controls but still align with the objectives of those controls and are holistically capable of achieving a positive planning outcome.

Ultimately, the best projects begin with a clear understanding of the site, the constraints and the desired outcome. By identifying your development goals early, you can determine whether time, cost or design flexibility will play the biggest role in the project's success and select the approval pathway that best aligns with those objectives.

A CDC may be the fastest pathway to construction, but a DA may be the pathway that delivers the outcome you've always envisioned.
