Building Code of Australia (BCA)

The BCA is a set of technical provisions outlining the minimum requirements for the design and construction of buildings in Australia. It covers aspects such as structural integrity, fire safety, access, and amenity. Understanding the BCA can help homeowners identify whether a contractor has adhered to the required standards and if the identified defects are in breach of the BCA.

National Construction Code (NCC)

The NCC is a uniform code that encompasses the BCA and the Plumbing Code of Australia. It sets the minimum requirements for the design, construction, and performance of buildings, plumbing, and drainage systems. Compliance with the NCC is achieved through meeting the relevant Performance Requirements, either by adhering to the Deemed-to-Satisfy Provisions or by developing a Performance Solution. Familiarising yourself with the NCC can help you determine if your contractor has met the necessary compliance requirements.

Australian Standards

Australian Standards are nationally recognized guidelines and specifications for a wide range of industries, including construction. They provide detailed technical information on building materials, design, and best practices. By understanding the applicable Australian Standards for your project, you can assess whether your contractor has followed the correct procedures and used suitable materials.

Leveraging the BCA, NCC, and Australian Standards in Your NCAT Dispute

To strengthen your case in an NCAT dispute, consider the following steps:

Identify breaches: Determine if the building defects are a result of the contractor not complying with the BCA, NCC, or relevant Australian Standards.

Obtain expert advice: Consult a building inspector, engineer, or other professionals to evaluate the defects and provide an expert opinion on the contractor’s compliance with the relevant regulations.

Document evidence: Collect documentation, photographs, and expert reports to support your claims of non-compliance.

Present your case: Clearly demonstrate how the contractor has breached the BCA, NCC, or Australian Standards in the construction of your home during the NCAT hearing.


Understanding the Building Code of Australia, National Construction Code, and Australian Standards can empower homeowners in NCAT disputes with contractors over building defects. By leveraging this knowledge, you can effectively identify non-compliance, gather supporting evidence, and present a strong case to achieve a fair resolution. Seeking expert advice and legal counsel can further strengthen your position and provide additional guidance throughout the dispute process.
