Approval and Inspection requirements - Classes 1, 10 & 10a

What Are Class 1a, 10 and 10a Buildings?

  • Class 1a: A standalone house, secondary dwelling such as a granny flat or townhouse 
  • Class 10: Non-habitable structure like a garage or carport 
  • Class 10a: Sheds, pool pump enclosures, or similar outbuildings 

Requirements

Do I Need Plumbing Approval? 

A plumbing permit is generally required before any work begins. Your licensed plumber or drainer should confirm this before starting. Under Section 39 of the Plumbing and Drainage Regulation 2019, 

Under the Plumbing and Drainage Act 2018, councils may offer 2-day fast-track approvals for low-risk plumbing work on Class 1 and Class 10 buildings. 

Council has chosen not to adopt this fast-track option. 

This helps us: 

  • Deliver consistent, high-quality customer service 
  • Allocate Council resources efficiently 
  • Ensure all plumbing approvals meet community standards and compliance requirements
