The National Construction Code (NCC) plays a pivotal role in defining the standards and classifications for various types of buildings. One such classification is Class 2, which applies to builders working on multi-unit residential buildings. In this article, we’ll delve into what Class 2 classification entails and what is required for Australian builders to legally undertake this type of work with full compliance.
What is Class 2 Classification?
Class 2 buildings are typically multi-unit residential buildings where people live above and below each other. These buildings include apartment complexes and other similar structures. The primary characteristic of Class 2 buildings is that they are designed for long-term residential use, with multiple units stacked vertically.

Requirements for Australian Builders
To legally perform Class 2 construction work in Australia, builders must adhere to specific requirements set forth by the NCC and other relevant regulations. Here are the key requirements:
- Licensing and Registration: Builders must be registered under the Design & Building Practitioners Act 2020 to work on Class 2 buildings. Builders must hold a valid contractor licence authorising them to perform general building work under the Home Building Act 1989. This includes obtaining a supervisor certificate if they are acting as a Body Corporate Nominee.
- Relevant Practical Experience: Builders must have a minimum of five years of relevant practical experience within the last ten years. This experience should involve carrying out building work on Class 2, 3, 9a, or 9c buildings.
- Educational Modules: Builders are required to complete two educational modules. The first module covers the Design and Building Practitioners Act 2020 and its regulations, while the second module focuses on the Environmental Planning and Assessment Act 1979 and the Building Code of Australia (Volumes 1 and 2).
- Compliance with NCC: Builders must ensure that their construction work complies with the technical requirements outlined in the NCC. This includes adhering to safety, design, and accessibility standards specific to Class 2 buildings.
- Exemptions and Additional Categories: Certain types of work, such as exempt development or waterproofing in specific areas, may not require full registration. Additionally, the NSW Government is considering adding further building practitioner categories to assist builders who may not have the full five years of experience.

While HV Aluminium does not perform Class 2 construction work, we are approved for Class 1 work on Class 2 structures. For instance, we constructed an Eclipse Opening Roof on a 4th story Class 2 building residence. The builder who constructed the building specialises in Class 2, while we only handled the Class 1 opening roof.
