The ABCB has 2 primary technical advisory committees, the Building Codes Committee (BCC) and the Plumbing Code Committee (PCC).

The BCC is a national forum for regulatory authorities and industry, to consider technical building regulation reform matters. It plays an active role in assisting the Board, through the Office, in achieving sound technical decision making. The remit of the committee is purely technical and it is not tasked with matters of policy direction. 

The BCC and PCC operate in alignment to ensure a coordinated approach to building and plumbing regulatory reform.
