Building warrant of fitness (BWOF)

What is a building warrant of fitness (BWOF)

A building warrant of fitness (BWOF) is an annual certificate that confirms that:

  • specified systems in your building have been inspected and maintained
  • requirements of the compliance schedule have been met.

What you need to do

As a building owner you have to:

  • engage an Independent Qualified Person (IQP) to inspect and certify the specified systems
  • display a copy of the BWOF certificate within the public area of the building
  • provide us with a copy of the BWOF and IQP certificate(s) of compliance.

Email relevant items to:

You should know

You need to display a BWOF, so that people using your building know that all the systems in the building are functional and operating effectively, without any risk to their health and safety.
If you don't display a BWOF, or display a false one, you can get a fine of up to $20, 000.

If your BWOF has expired, you may be prosecuted.

Inspections and on-site BWOF audits

Each year we conduct BWOF inspections and audits on randomly selected buildings.

You may be contacted to undergo an audit if:

  • it has been more than five years since your building was last audited
  • a BWOF renewal is overdue or where there is a history of BWOF renewals being supplied late
  • a building has had no building work done for an extended period of time
  • the BWOF and compliance schedule have not been reviewed for an extended period
  • your building is being investigated as a dangerous building.

Please note: this is not an exhaustive list.

The owner is liable to pay for the inspection.

For more information, see the MBIE website.
