Inspection certificates

All plumbing and drainage permit work (previously called ‘compliance assessable work’) is inspected by local government or a public sector entity.

The Plumbing and Drainage Regulation 2019 sets out the:

  • inspection process
  • alternatives to local government inspections
  • requirements for issuing inspection and final certificates.

Calling for an inspection

The responsible person for the work (i.e. plumber) must request that a local government inspect the plumbing and drainage permit work.

The Regulation prescribes the stages of the work to be inspected. Generally, work must be inspected either:

  • before being covered
  • no more than 5 days after a stage has been reached.

Inspection certificate

The inspection certificate is a form that a local government or public sector entity uses to record the results of an inspection of a plumbing and drainage work stage, as authorised by the permit:

The certificate states that the permit work complies with the code requirements.

Depending on the stage, it may also state that some or all of the work is operational and fit for use.

An inspection certificate is only issued if the responsible person makes a written request to the local government.

The certificate must be issued within 2 business days after either the inspection or the local government receives a covered work declaration.

Alternatives to local government inspections

In some cases, a local government may accept a declaration or report from a responsible person for the plumbing and drainage work.

These include:

Final inspection certificate

The local government or public sector entity uses Form 19—Final inspection certificate (PDF, 88KB)​ to certify that the permit work is compliant, operational and fit for use.

They can issue the form when all work under the permit or a distinct part of the work (e.g. one or more townhouses in a complex) is complete.

The form is issued to the responsible person for the work, and copies are issued to the permit holder and owner.

Using plumbing and drainage before inspection

Noone can use plumbing or drainage that is the result of permit work unless an inspection certificate or final inspection certificate has been issued stating that the work is operational and fit for use.

A maximum penalty of 250 penalty units applies ($32,637.50).

When inspection certificates aren’t required

A local government doesn’t need to issue an inspection certificate or final inspection certificate if both:

  • an action notice has been issued relating to the work or part of the work
  • the action notice has either
    • not been complied with
    • been appealed and the appeal hasn’t ended
    • required an amended permit and the permit hasn’t been amended.

Failure to issue certificate

If the local government fails to issue an inspection certificate or final inspection certificate, the responsible person is entitled to an information notice.

An information notice about a local government decision states:

  • the decision
  • reasons for the decision
  • that the person receiving the notice may appeal to the Development Tribunal.

Local government register

A local government must keep a register containing each inspection certificate or final inspection certificate issued in relation to permit work.

They must keep the documents until the building or structure it relates to is demolished or removed.​
