The Building Services (Registration) Act 2011 requires that an individual, partnership or company that carries out, or contracts to carry out, 'builder-work' valued over $20,000 (within the area of jurisdiction) must be a registered building service 'contractor' and named as a builder on the building licence or permit.

Individuals that are registered building 'practitioners' can not contract with others to provide building services, but may wish to be the nominated supervisor of a registered 'building service contractor'.

Conditions on a builder's registration may relate to the Building Code of Australia Building Classifications.
