What Plumbing or Drainage Work Requires Council Approval?

All plumbing and drainage work in Queensland is regulated by state government legislative requirements and is categorised as:

  • minor work
  • notifiable work
  • permit work
  • unregulated work.

All plumbing and drainage work, except unregulated work, must be performed by an appropriately licenced and endorsed person. Only permit work is approved by Council and further information on permit work, how to lodge applications and the services offered by the Hydraulics Team is provided below.

Further information on plumbing and drainage can be found in our Plumbing and Drainage Frequently Asked Questions.

Permit work is any work that is not defined by regulation as one of the other categories of work. Generally, permit work is plumbing and/or drainage work for a new building, work for an existing commercial premise that includes sanitary drainage or trade waste, and any work within a property serviced by a combine house drain.

Permit work must be assessed by Council with approval given before commencing Plumbing and drainage work. Council will inspect permit work for compliance with the code requirements and the permit conditions before the work is covered. Once the permit work has been satisfactorily completed, Council will issue a final inspection certificate for the work.


Notifiable work extends the amount of work a plumber or drainer can perform without a local government permit or mandatory inspections. Notifiable work is defined in Schedule 2 of the Plumbing and Drainage Regulation 2019. It includes most plumbing and drainage work performed in existing homes including:

  • kitchen and bathroom additions and renovations
  • installing or replacing hot water heaters, including electric, solar or heat pump hot water heaters
  • installing fixtures such as toilets, showers and sinks in an existing home
  • extending or altering pipe work.

For more information on notifiable work visit the Queensland Building and Construction Commission (QBCC) website.


The Hydraulics Services fee structure uses fixture numbers to calculate assessment and inspection fees, the below information will help you to understand which fixtures are counted to calculate fees for the plumbing and drainage applications:

Fixture

A receptacle with necessary fittings designed for a specific purpose, the use or operation of which results in a discharge into the sanitary drainage installation.

To assist applicants in calculating fees, Townsville City Council will consider the fixtures and appliances listed on this page as chargeable fixtures. For applications involving civil works, early-stage work, or permit work that do not include fixtures, the City will calculate fees based on a meterage rate for:
