Reading the scope of a pre-purchase building inspection
What to ask before booking a pre-purchase building inspection, how to read its scope and access limits, and when a separate pest or specialist check helps.
A pre-purchase building inspection report is only as useful as the parts of the property the inspector could actually see. Before you book one, and again when the report arrives, the scope and the list of areas not inspected matter as much as the defects found. This guide shows what to ask before booking, how to read the limitations section and what the report can and cannot do for your decision, using New South Wales and Victorian government guidance.
Choose who inspects
The NSW Government recommends using a suitably qualified person, such as a licensed builder, a surveyor or an architect, and says the inspector should hold adequate insurance, particularly professional indemnity insurance. Consumer Affairs Victoria similarly suggests a qualified building inspector, surveyor or architect, points to the Building and Plumbing Commission to find a registered building practitioner, and recommends an inspection service with full professional indemnity insurance. Consumer Affairs Victoria also warns buyers to be wary of an inspection report offered by the agent or the seller, because commissioning your own is the way to make sure it is independent. Ask each inspector, in writing, for their qualification or registration, their insurance and a sample report so you can see how they record limitations.

Consumer Affairs Victoria: inspect properties before you buyAgree the scope before the inspection
NSW guidance says a report should include your name, the property address, the date of inspection and the scope of the inspection, along with a summary of overall condition, major faults and any recommendation for a specialist assessment. Ask which inspection standard and report format the provider uses, and request a sample report to compare with your brief. Before booking, send the inspector a short brief: The property type and age, and any outbuildings, retaining walls, decks or pools you want included. Anything you noticed at open inspections, such as cracks, damp patches or sloping floors. Renovations or extensions you know about. Whether you also want a pest inspection. Ask the inspector to confirm in writing what is included and what is not, and whether anything you listed needs a different specialist.

NSW Government: pre-purchase inspection reportsRead the limitations section first
NSW guidance says inspectors should check all accessible parts of the property but will not normally examine footings, concealed damp-proofing, electrical wiring, plumbing or swimming pools unless specifically asked. Access on the day also shapes the result: a locked room, a stored item against a wall or a roof space without safe access can leave an area uninspected. Hypothetical report reading, for illustration only. A report on a 1960s brick house says: roof space partly inspected (access restricted beyond the hatch area); subfloor not inspected (no access hatch found); rear deck inspected; electrical and plumbing outside scope. The defects list is short. Read that as "few defects found in the areas seen", not "few defects". Before committing, you might ask whether access can be arranged for the subfloor, and whether the inspector recommends a specialist for any item they could only partly assess.
Use the report for the decision it supports
Consumer Affairs Victoria says a written building inspection report will list faults in the property, whether they can be repaired and how much repairs are likely to cost, and will highlight unsafe or unauthorised renovations or extensions. It suggests the report can help you negotiate the price or contract conditions with the seller, or plan maintenance if you buy. NSW guidance adds an important limit: a building inspection report should not be used as a certificate of compliance with any law, or as a warranty or insurance policy against future problems. If the property has renovations, Consumer Affairs Victoria suggests checking the Section 32 vendor statement and contacting the council about whether planning or building permits were obtained, because illegal alterations may become your responsibility after you sign.

Pest inspections are separate. NSW guidance explains that a building inspection may note visible termite damage, while a pest report is aimed at whether termites are still active, which matters more where termites are a known problem. Consumer Affairs Victoria also suggests considering a pest inspection, and an asbestos assessment for a property built before 1990. If the inspector recommends a structural engineer, electrician, plumber or another specialist, follow that up before you are bound by the contract where possible. A boundary question, such as a fence that seems out of line, needs a registered surveyor rather than a building inspector.
