What Is a CDC and What Does a CDC Certifier Do?
A Complying Development Certificate (CDC) is a combined planning and construction approval that lets a qualifying project skip a full Development Application (DA). A CDC certifier is the registered professional who checks your proposal against the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (the Codes SEPP) and issues the certificate if it complies.
As private CDC certifiers, we assess eligibility, review your plans against every relevant standard, and issue the certificate directly, without your application sitting in a council queue.
Do You Need a CDC Certifier for Your Project?
A CDC certifier is required in the following situations:
You're building a new house or granny flat and want a faster approval path than a DA
You're adding an alteration, extension or internal fit-out that meets standard planning controls
You're constructing a commercial or industrial fit-out, change of use, or ancillary structure like a pool, shed or carport
You're demolishing an existing structure and need certification before work starts
You've been told your project might qualify as complying development but aren't sure it meets every standard
Not sure if this applies to your project? Contact us and we'll assess it for free.
How the CDC Certification Process Works
Free eligibility check: Send us your plans and site details. We check them against the Codes SEPP criteria to confirm complying development is genuinely on the table.
Lodge your application: Once eligible, you provide full architectural plans, your Building Sustainability Index (BASIX) certificate, structural details and any specialist reports needed.
Assessment against the Code: We review your proposal against the relevant Codes SEPP provisions, the Building Code of Australia (BCA), and any referenced Australian Standards.
Conditions and issue: We issue your CDC with the approved plans and any pre-commencement conditions, or come back to you fast if something needs fixing first.
Ongoing certifier support: If needed, we can continue as your Principal Certifier through construction, right through to your Occupation Certificate.
Timeframes
Most CDC applications are determined within 7 to 10 business days of a complete application. The statutory limit is 10 business days for most complying development, or 20 business days where neighbour notification applies, such as new dwellings and some alterations.
Incomplete documentation, a proposal that fails even one numerical standard, or site constraints like heritage listing can extend this or push the project into the slower DA pathway instead.
