Understanding the Complying Development Certificate (CDC) Process in NSW
A Complying Development Certificate (CDC) is a fast-tracked planning and construction approval process. It is designed for straightforward residential, commercial, and industrial development that meets specific, pre-determined state government criteria.
Because the rules are set at the state level (under the State Environmental Planning Policy or SEPP), the approval process is significantly faster than a traditional Development Application (DA), often taking only weeks rather than months.
The Three Pillars of CDC Eligibility
To qualify for a CDC, your project must align with three core factors:
-
Project Type: What you wish to build (e.g., a new home, renovation, or granny flat) must be permitted under Complying Development rules.
-
Land Zoning: Your Section 10.7 Certificate (formerly 149 Certificate) must confirm that your land is zoned for the proposed work and isn’t subject to restrictions that disqualify CDC (such as high-risk bushfire or certain heritage categories).
-
Specific Controls: Your design must adhere strictly to numerical standards, including building height, setbacks from boundaries, and site coverage.
Who Approves a CDC?
Unlike a DA, which is assessed by local Council planners, a CDC is issued by a Private Certifier (or a Council Certifier acting in a private capacity). They act as the “judge” to ensure every technical requirement is met before endorsing construction.
Required Documentation for a CDC Submission
The following documents are essential for a successful CDC application. At JJ Drafting & Design, we specialize in collating this technical package to ensure a smooth approval.
Standard Architectural & Technical Plans
-
Detailed Floor Plans: Precise layouts of the proposed works.
-
Elevations & Sections: Vertical views showing heights and structural depths.
-
Site Calculations: Confirming floor space ratio (FSR) and site coverage.
-
Stormwater Concept Plans: Demonstrating how rainwater will be managed.
-
Landscape Calculation Plans: Ensuring minimum “green space” requirements are met.
-
Erosion & Sediment Control Plans: Protecting the site during the build.
Essential Compliance Reports
-
BASIX Certificate: Ensuring the design meets NSW sustainability targets for water and energy.
-
Site Survey: An accurate boundary and level survey conducted by a registered surveyor.
Specialized Reports (Site Dependent)
Depending on your specific lot, the following may be required:
-
Geotechnical Reports: For sites with potential soil or stability issues.
-
Flood & Bushfire Risk Reports: Necessary if your land is identified as being in a high-risk zone.
-
Engineering Drawings: Structural details for slabs, frames, and retaining walls.
-
Hydraulic Drawings: Advanced drainage or on-site detention systems.
