Occupancy Permit
Responsible agency
Department of Mines, Industry Regulation and Safety
The Building Act 2011 commenced on 2 April 2012, introducing a new building approval process for Western Australia and bringing in some significant changes to the building approvals process, from the design stage right through to occupation of a building. 

Occupancy Permits are required in order to occupy multi-residential, commercial and public buildings.  The occupancy permit sets out the building’s classification under the Building Code of Australia and the use approved under planning laws.

An occupancy permit may require inspections or tests of equipment or systems to ensure that the building remains safe to occupy.

An occupancy permit is used to:

  • occupy a completed building, following on from a building permit;
  • occupy an unfinished building on a temporary basis;
  • approve temporary change of use of a building, for a period of up to one year;
  • approve permanent change of use of a building;
  • confirm a building is suitable for registration of strata;
  • retrospectively approve unauthorised building or demolition work; and
  • bring an authorised existing building into the new building control system.

An Occupancy Permit can be obtained from our web site see:
