Building classification

​There are 10 classes of buildings defined under the Building Code of Australia (BCA), each of which has a different use. Queensland uses these same general classifications in its building standards.

In April 2008, Queensland passed laws to improve building safety under the Building Act 1975. These laws require building owners to display a certificate of classification in all new buildings other than a single detached house (class 1a building) and carports and garages (class 10 buildings).

It is important to have a certificate of classification as it specifies the building’s class and the way it can be used. For example, a certificate for a retail shopping centre would identify the building as a class 6 building, which is a shop or other building for the sale of goods by retail or the supply of services direct to the public.

Local governments, building certifiers, building owners and other stakeholders can use the following comprehensive documents below of what information is to be included in a certificate of classification and where these certificates should be displayed.
This publication was produced prior to the current government.
