The NCC is an initiative of the Council of Australian Governments developed to incorporate all on-site building requirements into a single code. The NCC sets the minimum requirements for the design, construction and performance of buildings throughout Australia.

The list below is a summary of the NCC classes for different building types*. Commercial scale buildings are further divided into Types based on the rise in storeys. Check with the relevant project certifier to determine your NCC class, and any additional requirements.

Class 1a: A single dwelling being a detached house, or one or more attached dwellings, each being a building, including a row house, terrace house, townhouse or villa unit.
Class 10: A non-habitable building or structure.
James Hardie has the following wall solutions for Class 1a and Class 10 buildings:

Class 2: A building containing 2 or more single-occupancy units each being a separate dwelling. 

Type of Construction: Class 2 buildings are separated into types.



Class 9c: Building for residential accommodation of aged persons.
