Approval and Inspection requirements - Classes 2-9

What are Class 2 to 9 Buildings?

These are building classifications under the National Construction Code and refer to everything other than houses or townhouses (Class 1). 

  • Class 2 - Apartments or multi-unit dwellings 
  • Class 3 - Hotels, motels, boarding houses 
  • Class 4 - A sole residence inside a commercial building 
  • Class 5 - Office buildings 
  • Class 6 - Shops, cafés, restaurants 
  • Class 7 - Warehouses, storage facilities 
  • Class 8 - Laboratories, factories 
  • Class 9 - Public buildings like hospitals, schools, and assembly spaces 

These classes cover commercial, industrial, and larger residential buildings, all of which have specific plumbing and drainage approval requirements. 

Do I Need a Plumbing Permit?

Yes. A permit is required before any licensed plumbing or drainage work begins on Class 2-9 buildings (e.g. commercial or multi-residential properties). 

Important: Council does not process fast-track plumbing applications under Section 39 of the Plumbing and Drainage Regulation 2019.
