Common questions about building inspections in Australia

Whether you're buying your first home or your fifth, it's normal to have questions about what a building inspection involves, when to book one, and what it costs. Here are answers to the questions we hear most often.

What does a building inspection cover?

A standard building inspection assesses the overall condition of a property, including the roof structure, subfloor, exterior walls, internal walls and ceilings, windows and doors, plumbing and drainage, and any visible defects. Reports are prepared in accordance with Australian Standard AS 4349.1.

The inspector will note major defects, minor defects, and items requiring ongoing maintenance. They will not assess hidden areas such as inside walls, electrical wiring, or plumbing pipes unless a specialist inspection is arranged separately.

Do I need a pest inspection as well as a building inspection?

Yes — it is strongly recommended to obtain both. Pest inspections, particularly for termites, are conducted separately and assess evidence of timber pest activity, damage, and conditions conducive to infestation.

Termite damage is one of the most costly surprises a buyer can face after settlement, and it is not always visible to the untrained eye. Many inspectors offer combined building and pest inspections as a package, which can be more cost-effective than booking them independently.

When should I book a pre-purchase inspection?

Ideally before you sign any contracts or make an unconditional offer. For properties sold at auction, you should arrange a pre-auction inspection in the days leading up to the sale, since you cannot make your bid subject to inspection after the hammer falls.

Inspections typically take two to three hours depending on the size and age of the property. You will usually receive a written report within 24 hours of the inspection being completed.

How much does a building inspection cost in Australia?

Costs vary by property size, location, and inspection type, but as a general guide:

• Building inspection only: $300–$700
• Combined building and pest inspection: $500–$1,000
• Larger or older properties may attract higher fees

Prices can also differ between states and between metropolitan and regional areas. Searching InspectorFind lets you compare quotes from multiple local inspectors so you can be confident you're paying a fair price.

Can I attend the inspection in person?

Yes, and it is encouraged. Being present gives you the opportunity to ask questions as the inspector works through the property, and to get a clearer sense of which findings are serious and which are routine. A good inspector will walk you through their key observations before they leave.

What happens if serious issues are found?

A report with major defects does not necessarily mean you should walk away. It gives you leverage to renegotiate the price, request that repairs be completed before settlement, or budget for work after you move in. Your conveyancer or solicitor can advise on the best approach based on the report findings.
