The National Construction Code 2022: What Does It Mean For Builders?


Implementation of the NCC 2022 is just around the corner - and it'll have big implications for the way Australian houses are built well into the future.

But what will the NCC 2022 change specifically and when is it set to be adopted?


What's Changing With The NCC2022?

7-Star NatHERS Minimum 

The biggest change will be the shift in the National Home Energy Rating Scheme (NatHERS) minimum from 6 stars to 7 stars, forcing significant changes in the design, layout, materials, insulation and orientations of future homes.

Expect increases in the demand for double glazing, low-E glass, and materials with higher-performing u-values.

Liveable Housing Design

The NCC also specifies new “Liveable Housing Design” standards, which are accessibility conditions designed to meet the needs of older people and those with mobility limitations – separate from specialist accommodation specifications.

These will include wider doorways, limited mobility access to a lower-floor bathroom, at least one step-free entrance and a pathway to the property boundary. 

Condensation Mitigation

Provisions to reduce condensation and water vapour in the interest of public health will also be a feature of NCC 2022. This is to be achieved with a more extensive verification process for envelope sealing, plus greater exhaust, material and insulation standards. 

When Will The NCC Come Into Effect?

Stage 1 implementation (which will include all facets of the code, excluding the Liveable Housing Provisions and the NatHERS 7 Star efficiency ratings) will come into effect from the 1st of May 2023.

Stage 2, which will include all remaining aspects of the code will come into effect from the 1st of October 2023.
