CDC Approval for Complying Developments in Sydney
Looking for a faster path to construction approval? A Complying Development Certificate (CDC) might be the answer!
What Is a Complying Development Certificate and Why It Matters
A Complying Development Certificate (CDC) is a form of development approval that combines both planning and construction approval in one streamlined process. This approach, often referred to as combined planning, is ideal for routine, low-impact development types.
Unlike a development application (DA), which is assessed by your local council, a CDC approval is issued by a private certifier or accredited certifier, provided your project complies with all applicable state environmental planning policies and building code requirements.

Did You Know?
Our team handles the entire approval process, ensuring your proposed building project meets all planning rules, building standards, and certification requirements under the NSW Government’s planning system.
When Can You Use the Complying Development Pathway?
The complying development pathway is available for a wide range of residential, commercial, and industrial development projects that meet strict criteria. This includes:
- Secondary dwellings, granny flats, and swimming pools
- Residential sheds, garages, and minor earthworks
- Strata subdivision, demolition, and structural supports building
- Internal alterations and upgrades that do not alter the external façade
- Industrial buildings that meet relevant land zoning rules
We assess your proposed development against applicable planning controls, development standards, and restrictions that may override private covenants. If your project qualifies, we will help you access the fast track approval process.
CDC Approval vs. Development Application (DA): Key Differences
While both options provide development approval, the CDC process offers a faster and more defined pathway, provided your project is eligible.
| Feature | Complying Development Certificate (CDC) | Development Application (DA) |
|---|---|---|
| Assessed by | Private certifier | Local council |
| Timeline | 2-4 weeks after submission | 2-6 weeks or more after submission |
How the CDC Approval Process Works
The CDC process involves several stages. Dura Group manages every step of this application process to ensure a smooth experience from concept to construction.

Step 1: Site Review and Eligibility Check
We evaluate your site, zoning, and overlays to confirm if the project qualifies for a complying development certificate. This includes checking for secondary dwelling building earthworks, vegetation protection, or nearby heritage-listed properties.

Step 2: Prepare Structural Plans and Required Documents
Our team compiles all the required paperwork, including:
- Detailed site plans and structural plans
- Building specifications tailored to your project
- Fire safety design to improve fire safety
- Reports for strata subdivision demolishing, setbacks, and height limits
- Compliance checks with state environmental planning policies
If your project includes specific construction material or unique designs, we ensure they align with relevant development standards.

Step 3: Engage an Accredited Certifier
We work with an experienced certifying authority or private certifier to review your plans and issue the complying development certificate approval. Any required adjustments are made quickly to avoid delay.

Step 4: Construction Certificate and Building Establishing
After approval, we assist with your construction certificate, manage pre-construction compliance, and help you begin building establishing within the allowed timeframe.
