The NCC 2022 will apply to all Construction Certificate and Complying Development Certificates Applications lodged after this date. There are also some further transition periods around Energy Efficiency, Condensation Management and Livable Housing Standards being introduced.
With the commencement of NCC 2022, updated Australian Standards also come into effect on the same date.
The below is a key summary of changes for Class 1 & 10 Buildings (Volume 2), however it is not an exhaustive list.
For Class 1 & 10 Buildings
Volume 2 has been restructured, re-numbered and split into two documents:
These are available free of charge at https://ncc.abcb.gov.au/
Part H4D2 of the NCC Volume 2 2022
Firstly, compliance to the new Housing Provisions Part 10.2.1 – 10.2.6 includes the overarching requirements for which areas in Wet Areas must be waterproof versus water-resistant. This includes a key update from the NCC 2019 that shower walls must now be waterproof, rather than previously water-resistant.
Secondary, compliance with technical aspects such as falls, step downs, materials, penetrations, drainage and all other matters can be satisfied with one of two options.
Industry will need to select one of the two above options for each project. Some key variances between the two options are summarised below. As industry adopts these new changes, we foresee further discussion around the variances and practical implementation of these requirements.
Part H4D9 of NCC 2022 & Part 10.8 of Housing Provisions

The minimum level of thermal performance of new homes is raised to the equivalent of 7 stars under the Nationwide House Energy Rating Scheme (NatHERS).
Part H8 of the NCC Volume 2 2022 & ABCB Standard for Livable Housing Design
The Livable Housing Standards is one of the more substantial changes to mandatory requirements for Class 1a Dwellings, requiring these to “better meet the needs of the community, including older people and people with mobility limitations”. The requirements are similar to the ‘Silver’ level requirements of the Livable Housing Design Guidelines, including below:
Note: The states have taken various approaches to adoption of Part H8:
NCC Part 11.3
NCC Part 12.4
