Underpinning Licensing & Rules in Western Australia

Important regulations and resources to help you hire with confidence in Western Australia.

Building contractor registration

A building contractor registration is required to contract for building work that needs a building permit and is valued at $20,000 or more. Applicants must be registered building practitioners and meet financial and supervisory requirements.

Building permit required

A building permit must be obtained before undertaking building work that could affect structural soundness or safety, such as underpinning. Work cannot commence until the permit is granted by the local permit authority.

Home indemnity insurance

For residential building work over $20,000 requiring a permit, builders must take out home indemnity insurance in the owner’s name before accepting any payment or starting work. The certificate must accompany the permit application and covers the project for six years.

Certificate of design compliance

Certified building permit applications must include a certificate of design compliance signed by a registered building surveyor. Engaging a building surveyor is typically the first step in the approval process.

General construction induction card

Anyone carrying out construction work must hold a White Card obtained through accredited training. Cards from other jurisdictions are recognised.

Occupancy and completion requirements

After finishing underpinning, the builder must lodge a notice of completion within seven days and obtain an occupancy permit before the building can be used. Occupying a building without a permit is an offence.
