Interior Designing Licensing & Rules in Western Australia
Important regulations and resources to help you hire with confidence in Western Australia.
No current licence for designers
Western Australia has no mandatory registration scheme for building designers or interior designers. The state is reviewing the regulation of building designers (non-engineers), and further information will be released.
Comply with Building Act and NCC
All building work must comply with the Building Act 2011 and the NCC. Building permits are required for new buildings and major alterations, and plans must meet structural, fire and accessibility standards.
Engage licensed builders and trades
Interior designers must not carry out construction, plumbing or electrical work. Structural modifications and services installations must be undertaken by registered builders, plumbers and electricians.
Professional indemnity insurance
There is no legislated PI insurance requirement for designers in WA, but professional indemnity and public liability insurance are strongly recommended. The government is considering introducing mandatory insurance requirements in future reforms.
Stay informed on reforms
The Building and Energy division is modernising WA’s building laws and auditing design, certification and construction processes. Designers should monitor updates and participate in consultations on new licensing requirements.
Join professional organisations
Membership of the Design Institute of Australia or Building Designers Association of Western Australia provides access to accreditation, a code of ethics and CPD programs. Membership is voluntary but supports professional recognition.
