WA state variations to the National Construction Code 2022 (NCC 2022) relating to the installation of eaves, gutters and downpipes came into effect on Thursday 1 May.

Building and Energy have published Industry Bulletin 168 to inform the industry about these variations, which are part of NCC 2022 Variation 1.

Industry Bulletin 168 says the variations offer additional compliance options that may be more readily achievable using WA building practices and products.

A very brief summary is that the plumbing and drainage standard AS/NZS 3500.3:2021 can now be used in conjunction with the Australian Building Codes Board's Housing Provisions Standard.
