The two approval pathways: DA vs CDC

Most NSW residential projects go through one of two approval pathways, and the cost is very different:

Complying Development (CDC)

$3,000–$8,000

Fast-tracked approval by a private certifier, usually 10–20 days. Available when your project meets the state Complying Development codes. No council assessment or advertising fees.

Development Application (DA)

$5,000–$25,000+

Full council assessment, typically 40–90+ days. Required for anything that doesn't meet the CDC codes. Adds lodgement, advertising, referral and often Section 7.11/7.12 contribution costs.

Frequently asked questions

How much does a CDC cost in NSW?

A Complying Development Certificate from a private certifier is typically $3,000–$8,000, plus the planning portal fee and any consultant reports. It avoids council DA assessment and advertising fees.

Do I still pay council fees if I use a private certifier?

Yes. The certifier issues your CDC/CC and acts as Principal Certifier, but you still pay council-level charges — Section 7.11/7.12 contributions, the Long Service Levy, and any damage or infrastructure bonds.

What's the difference in cost between a DA and a CDC?

A CDC is usually cheaper and far faster ($3k–$8k, ~10–20 days) than a DA ($5k–$25k+, 40–90+ days), because it skips council assessment, advertising and often contributions. Not every project qualifies for a CDC.

What are the hidden costs people forget?

The Long Service Levy, Section 7.11/7.12 contributions, HBCF insurance, refundable bonds you have to chase, and the stack of consultant reports (engineer, surveyor, BASIX, and for units — fire, acoustic and accessibility).
