  • is of a value of either:
    – $50,000 or more if the work relates to a Class 10a building; or
    – $20,000 or more for other types of building work; and
  • is carried out in the prescribed area of the State.

There are a number of exemptions to the above (refer to the following pages).

What is a Class 10a building?

A Class 10a building is defined in Volumes One and Two of the National Construction Code as a non-habitable building including a private garage, carport, shed or the like. 

Refer to your building surveyor or relevant local government permit authority to determine the correct building classification.

When is a building permit required?

A building permit is generally required for building work that includes:

  • the construction, erection, assembly or placement of a building or an incidental structure;
  • the renovation, alteration, extension, improvement or repair of a building or an incidental structure;
  • the assembly, reassembly or securing of a relocated building or a relocated incidental structure; or 
  • the changing of ground levels and site works associated with one of the above points.

Building permits are granted by local government permit authorities in the area in which the proposed building work is to be carried out. To determine whether a building permit is required you must seek advice from the relevant local government permit authority.

What is the prescribed area of the state?

The area prescribed encompasses 122 of WA’s local governments. In some areas of low population only major town sites are included. Further detail is available on the Builder's registration map.
