Written by Fox Modular | 21 April 2023 | Modular Homes

When it comes to building modular homes in Western Australia, one of the biggest questions related to building permits. What permit do you need to build a modular home (or prefab home)? What are the costs involved? How long will the process take?

To help you out, we’ve put together some information around building permits in WA.

When are building permits required?

First things first – what is a building permit? A building permit is required before any kind of building works can take place on your new home. According to the Department of Mines, Industry, Regulation and Safety, a building permit is 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 incidental structure;
  • The assembly, reassembly, or securing of a relocated building or a relocated incidental structure; or
  • The changing of ground levels associated with one of the above points.

Who grants building permits?

In Perth and WA, building permits are granted by a permit authority, which is generally your local Council. Anyone can apply for a building permit. At Fox Modular, our team can take care of the process for you for a Fox Build & Install build, submitting all necessary paperwork to the relevant parties.
