A registered Commercial builder is responsible for managing and arranging the carrying out of all components of building work for the construction of commercial buildings and structures. These include class 2–9 buildings and structures, and class 10b buildings not associated with a domestic building, as classified by the Building Code of Australia.
You can apply to register as a Commercial builder (unlimited), or there are 10 limited classes of commercial building work. A person registered in a limited commercial builder class will be limited to certain types of work, such as waterproofing, non-structural fit-outs or the installation of blinds and awnings.
For a complete list of the limited commercial builder classes, see the Experience statements and Technical referee reports section below.
