If you're planning a straightforward home renovation, a granny flat, or even a new one or two-storey home in New South Wales, you might be eligible for a faster approval pathway: a Complying Development Certificate (CDC).

 

As the official NSW Government Planning Portal explains, CDC is a "fast-tracked application process that combines planning and construction approval" for straightforward projects. Approvals can be issued in as little as 20 days – or just 10 days for projects following the NSW Housing Pattern Book.

 

This guide explains what a CDC is, what projects qualify, and how the process works.

​

 

What is a CDC and Why Choose It?

 

A CDC is an integrated planning and construction approval. Unlike a full Development Application (DA) submitted to council, a CDC is assessed against predetermined, objective standards. If your proposal meets these specific criteria, it can be approved quickly by either your local council or an accredited private certifier – without the need for a full, often lengthier, DA process.

 

This makes it an ideal pathway for projects that are compliant by design, offering speed and certainty.

​

 

What Types of Projects Can Use the CDC Pathway?

 

The NSW Government provides a clear list of examples. Common residential projects eligible for a CDC include:

• Building a new 1 or 2 storey home

• Building a granny flat or secondary dwelling

• Renovating or adding to a home

• Building a swimming pool

• Building a fence

• Demolishing a building

• Certain earthworks and structural supports

 

It's designed for developments that are considered straightforward and meet the strict standards set out in the State Policy.

The CDC Application Process: A Step-by-Step Guide

 

Applying for a CDC involves several key stages, designed to be efficient but still thorough.

 

Step 1: Check Your Eligibility

Before anything else, you need to confirm your project falls under the complying development criteria. This involves checking your property's zoning, the specific development standards (like height, floor space ratio, and setbacks), and whether any site constraints (like bushfire or flood risk) apply. The official guide notes that CDC can be used on bushfire prone or flood-prone lots, but must meet specific code requirements.

 

Step 2: Prepare Your Documentation

A successful application requires a complete set of documents. The NSW Planning Portal checklist includes:

• A certificate of title for your property.

• Detailed design plans (site plan, floor plans, elevations).

• Structural plans and building specifications.

• Any other documents required by your council or certifier.

 

This is where professional design expertise ensures your plans are accurate and compliant from the start.

 

Step 3: Lodge Your Application

You can apply online through the NSW Planning Portal. You'll need to register for an account and submit all your documentation digitally. You'll nominate whether you're applying to your council or a private accredited certifier.

 

Step 4: Assessment and Approval

The certifying authority (council or private certifier) will assess your application against the relevant codes. If everything meets the standards, a CDC can be issued remarkably quickly – often within weeks, not months.

 

Important Consideration:

The official website stresses that "complying development does not override private covenants or similar legal instruments." This means any existing restrictions on your land title (e.g., requiring specific materials) still apply and must be considered.

Conclusion: Speed and Certainty with Professional Guidance

 

The CDC pathway offers a fantastic opportunity to get your project approved and started faster. However, its success hinges on one critical factor: your project must precisely meet all the required development standards from the very beginning. A single error in measurement or interpretation can lead to delays or refusal.
