National Construction Code 2022 - Northern Territory variations

As part of the preparation for the adoption of the National Construction Code (NCC) 2022, the Northern Territory (NT) Government reviewed its variations to provisions and requirements.

As a result of this review, the following variations that will be removed or modified as part of NCC 2022:

  • NCC Volumes 1 and 2 Section B, Structure, NT 4 Masonry veneer - removal of variation
  • NCC Volumes 1 and 2 Section H, NT Additions - Special Use Buildings - premises to be used for activities involving skin penetration and mortuaries - removal of variation
  • NCC Volume 2 Energy Efficiency of residential buildings (Class 1 and Class 10a) - amended variation
  • NCC Volume 1 Energy Efficiency of commercial buildings (Class 3 and Class 5-9) - modified to adopt NCC 2019 provisions effective from 1 October 2023
  • NCC Volume 3 Part B2 Heated water services - removal of variation, and
  • NCC Volume 3 Part C Sanitary Drainage Systems - removal of variation.

Of particular relevance is the modification of the NT variation for residential energy efficiency, which currently references the Building Code of Australia (BCA) 2009 provisions.

Changes to the NT variation for residential energy efficiency has been made to simplify the NT variations for energy efficiency - BCA 2009 vol 2, by making use of the new NT variation easier to understand.

The additions are to NT part H6 energy efficiency of the NCC 2022 - vol 2 and they reference NT part 13.1 of the housing provisions.

There will be no changes to NT section J energy efficiency for a class 2 and class 4 building as per the BCA 2009.

For further information regarding the adoption of section J for class 3 and 5 to 9 buildings in the NT, view building energy efficiency provisions.

The general provisions of the NCC 2022 will come into effect 1 May 2023.
