What does the BCA cover?



The BCA contains the technical requirements for buildings according to class, i.e Class 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10.

The BCA is split into two distinct volumes.

Volume One governs requirements for:

  • Class 2 to 9 buildings (commercial buildings);
  • access requirements for people with a disability in Class 1b and 10a buildings; and
  • certain Class 10b structures including access requirements for people with a disability in Class 10b swimming pools.

Volume Two governs requirements for:

  • Class 1 and 10a buildings (other than access requirements for people with a disability in Class 1b and 10a buildings) (housing provisions);
  • certain Class 10b structures (other than access requirements for people with a disability in Class 10b swimming pools); and
  • Class 10c private bushfire shelters.

The housing provisions are significantly different from those for commercial buildings. The clauses are written in plain English with diagrams to explain the code requirements. Non-mandatory explanatory information also accompanies clauses to assist users in understanding the requirements of the code. The code has been structured to follow the normal construction sequence, commencing with site works and progressing through the various construction stages to completion.
