One of the Australian Building Codes Board's (ABCB) primary roles is to update and maintain the National Construction Code (NCC) to ensure it is part of an effective and contemporary regulatory system. Potential changes to the NCC must be considered in accordance with the Regulatory Impact Analysis Guide for Ministers Meetings and National Standard Setting Bodies and be subject to regulatory impact analysis. The ABCB investigates alternative means of achieving a desired result, and if intervention is necessary, the NCC sets the minimum regulatory requirements that are proportional to the issue addressed.
The NCC is updated based on feedback from users through the Board's Proposal for Change process, to reflect agreed outcomes from the Board's work program, and to action Government policy decisions.
The process of developing a new edition of the NCC includes producing drafts, conducting Regulatory Impact Analysis, seeking and analysing public comment, consideration by the Building Codes Committee and Plumbing Code Committee and endorsement by the Board.
