There are ten types of building classifications under the Building Code of Australia.

Have you ever wondered what class of building you live, work or play in?

Well, the Queensland Building and Construction Commission (QBCC) has recently released a document that makes it easy to determine building classification.

When it comes to residential properties, most are Class 1’s and Class 10’s. For instance, Class 1a is a single detached house (dwelling) or one or more detached dwellings, each being separated by a fire-resisting wall including a residential house, town house or villa unit. Most homes in your neighbourhood will be Class 1a’s.

Class 10’s have three divisions, Class 10a including: private garages, carports, sheds and patios; Class 10b including structures such as: fences, swimming pools, retaining walls and the like. Class 10c is not as common, but is a private bushfire shelter.

Why are classes important?

Building classification determines what a building can be used for, whether it be to store items or to live in. For example, someone may like to live in a Class 10a shed, but because a Class 10a doesn’t meet the standards that a Class 1a dwelling has to, it is not lawful to do so.

It is possible to change the classification of building if you meet the standards set forth in The Building Act, but you will need to contact a certifier to help you with this.
