Individuals, partnerships and companies that wish to contract with others to provide building work valued over $20,000 must be registered as a 'building contractor' and demonstrate both financial and organisational capacity.

Refer to the Building Services Board’s ‘Management and Supervision Policy’ for details of the financial and organisational requirements. The Building Services Board generally requires an applicant for building contractor registration to demonstrate access to a minimum of $50,000 in cash or cash equivalent and have a quick ratio of at least 1:1 to meet the financial requirements. Partnerships and companies will also be required to have at least one nominated supervisor who is a registered 'building practitioner'.

It is important to note that a trust cannot obtain registration. The trustee of the trust must apply for registration however all documents and financial information provided must pertain to the trustee only.

Important changes to registration requirements as of 1 February 2023

As of 1 February 2023, the Building Service Board will have enhanced powers to manage the commercial conduct and behaviour of registered building service providers. These changes relate to certain events that occurred on or after this date.

It is important that you are aware of these changes as they may impact your application for registration. View full details of the changes here.
