Guiding information and access to application form for a building approval certificate.

Building Approval Certificate

In general a person must not carry out building work without a building permit where one is required. However the Building Act allows a person to make an application to the relevant permit authority to approve unauthorised building work in relation to a building and/or incidental structure. This retrospective approval process may assist those who are buying or selling a property that has an unauthorised structure on it.
Even though a person may seek retrospective approval for unauthorised building work, this does not remove the offence and a local government may still take legal action under the Building Act to ensure that the unauthorised building work is approved or removed.
