The National Construction Code (NCC) is a performance-based code which sets out the requirements for the construction of buildings, including plumbing and drainage.
The NCC has two different mandatory requirements:
- Performance Requirements outline certain criteria which must be met, and
- General Requirements which cover other aspects of applying the NCC. This includes its interpretation, reference documents, the acceptance of design and construction (including related evidence of suitability/documentation) and the classification of buildings within the NCC.
The NCC has both guidance information and compliance requirement. The Performance Requirements of the NCC being the minimum level that buildings, building elements and plumbing and drainage systems must meet. A building, plumbing or drainage solution will comply with the NCC if it satisfies the Performance Requirements.
