At CDDG, our team of experts helps homeowners, builders, and developers navigate the sometimes complex approval process. With decades of combined experience in DA approval experts, we make sure your project runs smoothly from start to finish.

Understanding Complying Development Certificates (CDC)

A Complying Development Certificate (CDC) is a fast-track approval option under NSW planning laws. It combines planning and construction approvals into one streamlined process. If your project meets all the predefined standards, you can bypass the longer Development Application (DA) route.

For example:

  • A granny flat CDC NSW allows homeowners to add a secondary dwelling without waiting months for council approval.

  • A house extension CDC Sydney can be completed quickly if your extension meets height, setback, and design criteria.

  • A swimming pool CDC NSW approval allows you to install or upgrade your pool safely and legally.


By choosing a CDC, you benefit from shorter approval times, less paperwork, and lower costs. However, it’s crucial that your project complies with the NSW State Environmental Planning Policy (SEPP). That’s where professionals like CDDG come in.

Development Application (DA) in NSW – When You Need It

Not all projects qualify for a CDC. In cases where your development does not meet the SEPP standards, you’ll need to lodge a Development Application (DA) in NSW with your local council. A DA is a formal request for permission to carry out development work.

Typical examples include:

  • Large-scale renovations or extensions

  • Building on environmentally sensitive land

  • Projects that don’t comply with zoning or setback requirements


The development application process involves preparing detailed plans, statements of environmental effects, and sometimes community consultation. Once submitted, the council will assess your application and either grant or refuse approval.

DA Approval Experts – Why You Need Professional Help

Submitting a Development Application (DA) is not always straightforward. Mistakes in your plans or documentation can lead to delays, additional fees, or outright refusal. This is why working with DA approval experts can make all the difference.

At CDDG, we specialise in:

  • Preparing and lodging your DA with the correct documentation

  • Liaising with local councils to expedite approval

  • Advising on how to modify your plans to comply with regulations

  • Ensuring your project meets both state and local requirements


By leveraging our expertise, you reduce the risk of delays and increase the likelihood of a successful outcome.

Granny Flat CDC NSW – Adding Value to Your Property

Building a granny flat CDC NSW is one of the most popular ways to increase property value and generate additional income. Whether you’re creating a home for elderly parents, a guest house, or a rental unit, a CDC can help you fast-track the process.

Key benefits include:

  • Faster approval times compared to a DA

  • Less red tape and paperwork

  • Compliance with strict design and safety standards


Our team can assess your site, prepare your documentation, and lodge your CDC application to ensure a smooth and stress-free experience.

House Extension CDC Sydney – Expand Your Living Space

If you’re outgrowing your current home, a house extension CDC Sydney could be the ideal solution. Extending your home under a CDC allows you to create more living space without relocating.

However, extensions must comply with specific rules about setbacks, height limits, and floor space ratios. CDDG can help you determine if your extension qualifies for a CDC and guide you through the application process. If it doesn’t meet CDC criteria, we’ll help you prepare a DA instead.

Swimming Pool CDC NSW – Safe and Compliant Pool Installation

A swimming pool CDC NSW approval ensures your new pool meets safety and environmental standards. From fencing requirements to water drainage, there are strict rules to follow. Our experts handle the paperwork, so you can focus on enjoying your new pool.

Step-by-Step Development Application Process in NSW

The development application process in NSW generally involves these steps:

  1. Pre-lodgement Consultation
    Meet with your local council or a private certifier to discuss your project’s feasibility.

  2. Prepare Documentation
    Prepare detailed plans, environmental impact statements, and any specialist reports required.

  3. Submit Your DA
    Lodge your application online or directly with the council.

  4. Council Assessment
    The council reviews your plans, consults with stakeholders, and may request additional information.

  5. Approval or Refusal
    If approved, you’ll receive a Development Consent outlining conditions you must follow.

  6. Construction Certificate (if required)
    Before starting work, you may need a construction certificate to ensure your plans comply with building codes.


Working with DA approval experts like CDDG simplifies this process. We handle the paperwork, track your application, and liaise with the council on your behalf.
