The National Construction Code (NCC) sets minimum standards for how buildings and plumbing systems are designed and built in Australia. It plays an important role in keeping homes safe, comfortable and fit to live in. However, the NCC does not cover every issue that can arise with a home. Knowing what it does and does not cover can help you understand whether an issue is related to the NCC or not, and where to go for help.

What the NCC covers

The NCC sets minimum requirements for things like:

  • structural safety and stability
  • fire safety features, such as smoke alarms and exits
  • health and amenity, including ventilation and natural light
  • energy efficiency
  • plumbing and drainage systems.

These requirements usually apply when building approval is needed, for example when building a new home, adding an extension or undertaking major renovations.

What the NCC doesn't cover

The NCC doesn't deal with every aspect of building work. It does not cover:

  • the quality of workmanship beyond the minimum standards
  • contract disputes with builders or designers
  • building costs, timelines or payment arrangements
  • ongoing maintenance issues in existing homes
  • product warranties or consumer guarantees
  • enforcing building laws or investigating complaints.

These issues are usually handled by builders, certifiers, local councils, state or territory building regulators, consumer protection agencies, or product manufacturers and suppliers.

The NCC sets minimum standards, but many common issues aren't covered by the NCC. The list below helps you quickly match your issue to the right place for help.

If your issue is about building approvals or compliance
Contact your local council or building regulator.

If your issue is about defects or disputes after construction
Contact your state or territory building regulator or a relevant tribunal.

If your issue is about workmanship or building contracts
Contact a consumer protection agency.

If your issue is about inspections, enforcement or complaints about building work
Contact your state or territory building regulator or local council.

If your issue is about warranties for building products
Contact your builder or the product manufacturer.

If your issue is about household products
(for example washing machines, dishwashers or air conditioners)
Contact the manufacturer, supplier or installer.
