What a Pre-Purchase Building Inspection Actually Costs in Australia

Pre-purchase building inspections in Australia are priced by a small number of factors: the size of the property, the age and complexity of the building, the location (metro or rural), travel time, and whether timber pest inspection is bundled in.

A combined building and pest inspection on a typical suburban house in a capital city is usually cheaper than commissioning each report separately, because the inspector only attends once. Strata and unit inspections are often priced differently again, reflecting the different scope and shorter typical attendance time.

Specialist add-ons cost extra. Thermal imaging, moisture meters, drone roof surveys, and detailed asbestos sampling are not part of a standard inspection and should be quoted separately. If you want them, ask up front, adding them on the day usually costs more.

The cheapest inspection is rarely the best value. A rushed, formulaic report from an under-qualified inspector misses the defects that matter. The cost of missing a major structural defect is many multiples of the cost of a thorough inspection.

When evaluating quotes, ask what Australian Standard the report is written to (AS 4349.1 for building, AS 4349.3 for pest), what licence the inspector holds, how long they have been inspecting in your area, and whether you can see a sample report.
