Building Classifications

Buildings and structures have different classifications under the Building Code of Australia. The most common classifications for residential properties are:

Class 1a – a single dwelling being:

  • a detached house
  • one of a group of two or more attached dwellings, each being a building, separated by a fire-resisting wall, including a row house, terrace house, town house or villa unit

Class 10a – a non-habitable building being a private garage, carport, shed, or the like

Class 10b – a structure being a fence, mast, antenna, retaining or free-standing wall, swimming pool, or the like
