The Licensing Landscape in WA

Western Australia does not have a dedicated ‘building inspector licence’ in the way that some other states do. Instead, the industry relies on the Australian Standard to deem someone a ‘competent person’. Naturally this can cause problems as not all newcomers have adequate building experience or knowledge. This is why it is so important to engage a reputable inspector.

The Building Services (Registration) Act 2011 governs who can carry out building work in WA. While this legislation does not specifically regulate building inspectors as a separate category, the expectation within the industry is that pre-purchase building inspections are carried out by professionals who hold registered builder qualifications.

KEY TAKEAWAY
There is no specific building inspector licence in WA. The industry relies on registered builder qualifications and the Australian Standard. Always verify your inspector’s credentials before booking.

Why Registered Builder Status Matters

A registered builder has completed formal training in building construction, understands the National Construction Code (NCC), and has demonstrated competency in assessing building work. This means they can identify defects that someone without building experience might miss entirely.

When you book a pre-purchase building inspection with a company that employs registered builders, you are getting an assessment from someone who understands how homes are built, not just how they look on the surface.

What Qualifications Should You Look For?

When choosing a building inspector in Perth, ask about the following before booking.

Builder registration

Ask whether the inspector holds current registration with the WA Building Services Board. You can verify this on the board’s public register.

Professional indemnity insurance

A reputable inspection company carries professional indemnity insurance and public liability insurance. This protects you if something is missed during the inspection.

Inspection standard

Confirm that the inspection is carried out under AS4349.1, the Australian Standard for pre-purchase inspections of residential properties. This standard defines the scope, methodology, and reporting requirements for the inspection.

Report quality

Ask to see a sample report before booking. A thorough report should include full-resolution photographs, clear descriptions of each finding, severity ratings, and recommendations for further investigation where needed.

The Risk of Choosing an Unqualified Inspector

The building inspection industry in WA is not as tightly regulated as many buyers assume. This means it is possible to book an inspection from someone who does not hold builder registration, does not carry adequate insurance, or does not follow the Australian Standard.

The consequences can be significant. A poorly conducted inspection may miss structural defects, active termite damage, or non-compliant building work. If these issues are discovered after settlement, the buyer has limited recourse, particularly if the inspector’s report did not meet professional standards.

As we explained in our article on whether the cheapest building inspection is worth it, the cost difference between a budget inspection and a thorough one is small compared to the potential cost of missed defects.

WHY IT MATTERS
An unqualified inspector is unlikely to hold adequate insurance. If defects are missed, you have very limited recourse after settlement.

How to Verify an Inspector’s Credentials

The WA Building Services Board maintains a public register where you can search for registered builders by name or registration number. If your inspector is not on this register, ask them what qualifications they hold and why they are not registered.

You can also check whether the inspection company is a member of relevant industry bodies. While membership alone does not guarantee quality, it indicates a commitment to professional standards.

How can I check if my building inspector is registered in WA?
