How to choose a building and pest inspector: the questions worth asking
Choose the inspector whose experience suits the property and whose written scope clearly covers the areas, structures and timber-pest work you need. Confirm independence, professional indemnity insurance, relevant state licensing, safe-access expectations, the report standard and whether you can speak with the inspector afterwards.

The written agreement should match the home and the decision.
Start with the home in front of you
Tell each inspector the address, property type, approximate age, storeys, construction, outbuildings, auction or contract deadline and any known access issue. Mention the specific concern that brought you to them, such as cracking, a low subfloor, a flat roof, a balcony leak or termite history.
The aim is a comparable written scope. A person who is excellent with new detached homes may have a different body of experience from someone who regularly reads period houses, apartments, retaining structures or complex additions.
Qualifications and licensing vary by state
Ask what qualification and experience support this particular inspection. The NSW Government recommends a suitably qualified person, giving a licensed builder, surveyor or architect as examples, and advises checking professional indemnity insurance.
Queensland has a specific QBCC completed residential building inspection licence class. Requirements elsewhere differ, so check the relevant state regulator and confirm that the person attending, as well as the contracting business, has the standing needed for the agreed work.
Building and timber-pest work can involve different competencies and authorisations. Ask who performs each part, what licence or qualification applies and whether the findings will appear in one report or separate reports.
Ask for the engagement agreement before booking
The agreement should identify the client, property, inspection type, included structures, access basis, exclusions, fee, timing, report format and the terms governing reliance. The AS 4349.1-2007 pre-purchase inspection standard provides a national framework for residential building inspections. Ask which standard and edition the service uses and how the agreed scope relates to it.
| Question | A useful answer should identify |
|---|---|
| Who will attend? | The individual inspector, relevant experience and the business responsible for the report |
| What is included? | Dwelling, site, garage, outbuildings, retaining walls, balconies and agreed timber-pest scope |
| What access is attempted? | Roof exterior, roof space, subfloor, internal rooms and conditions that may prevent safe access |
| What is excluded? | Services, concealed areas, compliance, estimates and specialist matters outside scope |
| What will I receive? | Written report, photographs, significant findings, limitations, recommendations and delivery time |
| Can I ask questions? | A direct conversation with the inspector and a process for written clarification or reinspection |
| What protects the engagement? | Professional indemnity insurance, complaint process and clear reliance terms |
Independence should be easy to explain
Ask who recommended the inspector, who pays them and whether they have a financial relationship with the agent, vendor, report marketplace, repairer or pest-treatment provider. A referral can still lead to capable work; a clear answer lets you understand the relationship.
Consumer Affairs Victoria advises buyers to use an inspection service with professional indemnity insurance and to be cautious with a report offered by the seller or agent. Read the Victorian inspection guidance before deciding whether a supplied report meets your needs.
Read a sample report
A sample reveals how the inspector thinks and communicates. Look for property-specific observations, useful photographs, precise locations, plainly stated access limits and recommendations that identify the next kind of expertise. A template can provide structure; the finished report should still feel like someone paid close attention to this home.
- Clear significance: the reader can tell what deserves attention first.
- Visible limitations: inaccessible areas are easy to find and understand.
- Traceable photographs: images have locations and connect to written findings.
- Proportionate recommendations: the next step answers a defined question.
- Human follow-up: the inspector is available to explain material findings.
Access often matters more than gadgets
Ask what safe-access conditions are needed for the roof exterior, roof space and subfloor, and who will arrange keys, hatches or permission. Tools such as moisture meters and thermal cameras can support defined observations. Their value depends on access, method, conditions and interpretation.
If a critical area is inaccessible on the day, ask about a return visit and its fee. Read the resulting limitation carefully using the guide to building and pest reports.
Choose the scope before comparing price
Put the quotes beside one another only after the inclusions line up. A lower price may reflect a smaller property, narrower access, building-only work, fewer structures, limited photographs or no follow-up. The inspection-cost guide and quote decoder provides current examples and a comparison framework.
Ask about cancellation, urgent turnaround, travel, reinspection and specialist follow-up fees. For an auction, leave enough time to read the report and act on it with the pre-auction inspection guide.

Frequently asked questions
What qualifications should a building inspector have?
Look for qualifications and experience relevant to the property and inspection scope. Government guidance recommends a suitably qualified professional, and state licensing requirements differ. Verify the person attending, their role and their insurance.
Do building inspectors need a licence in Australia?
Requirements vary by state and by the work performed. Queensland has a completed residential building inspection licence class. Check the regulator for the property location and the separate requirements applying to timber-pest work.
Should a building inspector have professional indemnity insurance?
Yes. NSW and Victorian buyer guidance both recommend checking professional indemnity insurance. Ask for current evidence and confirm which person and business the policy covers.
Should I use the building inspector recommended by the agent?
Ask about the relationship, scope, commissioning party and your reliance rights. Review the inspector on their qualifications, insurance, independence, access and report quality.
Does a building inspection include a pest inspection?
Only when timber-pest work is expressly included. Confirm who performs it, their relevant authorisation, the standard or scope used and how the findings will be delivered.
Is thermal imaging essential in a building inspection?
It can support a defined investigation under suitable conditions. It does not see through every surface or replace access, experience and careful interpretation.
How many quotes should I compare?
Enough to understand the available scope and fee for the property. Use the same written questions so you can compare access, inclusions, experience, insurance, report quality and follow-up fairly.
How this guide was researched
We turned the regulator and consumer guidance into the questions a buyer can actually ask: who is attending, what covers them, what they will reach, and what you get in writing.
Limits: Licensing, registration and timber-pest requirements vary by jurisdiction and service. Verify the individual, business, licence class and insurance for the property and work commissioned.
