What is a Complying Development Certificate (CDC)?
A Complying Development Certificate (CDC) is a fast-track approval pathway for eligible residential building projects in NSW. It combines planning approval and construction approval into one certificate, allowing work to begin without needing a separate Development Application and Construction Certificate process.

Complying Development Certificates Sydney FAQs
What types of projects can be approved with a CDC?
Many Class 1 and 10 residential projects may qualify for a CDC, including new homes, granny flats, duplexes, pools, garages, decks, pergolas, sheds, carports, and certain alterations or additions. Eligibility depends on zoning, setbacks, site conditions, and compliance with NSW planning controls.
Can a private certifier issue a Complying Development Certificate?
Yes. A qualified complying development certificate private certifier can assess your project and issue a CDC if it meets all planning and building requirements. This allows eligible projects to be assessed through a private certifier rather than a traditional council DA pathway.
Is CDC approval faster than a Development Application?
In many cases, yes. A CDC follows a set compliance pathway with clearly defined standards, which often makes approvals faster than a full Development Application. Timeframes depend on the quality of documentation and whether the project fully meets the required standards.
How long does CDC approval usually take?
Approval timeframes vary depending on the project and the supporting documents provided. Some CDC applications require neighbour notification periods depending on the project type and applicable planning requirements. Early planning and complete documentation help reduce delays and support a smoother approval process.
Do I still need inspections after CDC approval?
Yes. Once your CDC is issued and construction begins, mandatory critical stage inspections are still required throughout the build. These inspections help confirm that work is completed in line with approved plans and building standards before an Occupation Certificate can be issued where required.
How do I know if my project qualifies for a CDC?
This depends on your site, zoning, setbacks, building size, and the type of work proposed. Some projects meet CDC requirements, while others may require a full Development Application instead. A pre-CDC review helps determine the most suitable approval pathway before formal submission begins.
Can my project be approved through CDC or do I need a DA?
This depends on whether your project meets the specific planning standards for complying development. If it does, a CDC may be the faster approval pathway. If not, a Development Application may be required. Reviewing the project early helps identify the right path before plans are finalised.
