As an owner builder, you can build any residential building on your own property, as long as it complies with the necessary building codes and other regulations.

It is important to keep in mind that once the approval has expired, you will need to reapply for another approval before starting any construction work.

How to become an owner-builder?

To become an owner builder in Western Australia, you will need to:

  1. Submit an application to the Building Services Board
  2. Pass a mandatory owner-builder course
  3. Obtain Home Indemnity Insurance before commencing any construction

Once your application is approved, you will receive your owner-builder registration and you can start planning and building your new home.

Can I build again?

However, owner-builders can only be issued a building permit once every 6 years unless they have a special exemption.

The Owner-Builder's responsibilities when building your own home

As an owner-builder, it is your responsibility to ensure the building work is carried out properly and in compliance with the necessary regulations. Some of your responsibilities include the following.

Supervision of building work

It is important that you supervise and oversee all building work that is taking place on your site.

This includes ensuring that all tradespeople are licensed and insured and that all work is being carried out properly and to a high standard.

Displaying a sign

It is a requirement for owner-builders to display a sign at the building site identifying that the work being carried out is by an owner-builder.

The sign must include the registration number of the owner builder and must be displayed in a prominent position on the property.

Home Indemnity Insurance

Before starting any construction work, you will need to obtain Home Indemnity Insurance.

This insurance provides protection to any future owners of the property in case the owner builder dies, disappears or becomes insolvent during the construction process.

A word of caution

While it is possible to become an owner-builder in Western Australia, it is important to carefully consider if you have the necessary skills, knowledge, and time to undertake this project.

It's also not that easy get finance for owner-builders and most often they require much larger deposits compared to working with a professional builder.

There are many examples of owner-builder projects that have gone badly wrong and so it is not something we would recommend to anyone unless you have the necessary experience to perform the role to a high level of quality.
