Building and Pest Inspection: What You Need Before You Buy

What the inspections actually are🔗

Two separate assessments, usually done in one visit and combined into one report:

• Building inspection (AS 4349.1): a visual, non-invasive check of structure and safety, covering walls, roof and roof structure, foundations and subfloor, moisture and drainage, cracking, and safety hazards.
• Pest / timber pest inspection (AS 4349.3): checks for active termites and termite damage, borers, wood rot, fungal decay, and conditions conducive to pests (moisture, wood-to-soil contact, poor drainage).

The key word for both is visual: the inspector reports on what they can see and access. They cannot open walls, lift slabs, or enter unsafe areas. Most house buyers order both together as a combined report, which is faster and cheaper than separate visits.

Why you need one🔗

An inspection can uncover active termites, structural issues, dodgy unapproved DIY, rising damp, drainage problems and safety hazards, all of which give you real leverage as a buyer. You can:

• Renegotiate the price to cover repair costs.
• Ask the vendor to fix specific items before settlement.
• Add special conditions to the contract.
• Walk away before you are locked in.

The part many buyers miss: in most states, sellers are not legally required to disclose every defect. The onus is on you to find out what you are buying, and the inspection is how you do it. It pairs naturally with getting your conveyancer to review the contract.

How much it costs🔗

A $500 inspection that reveals $30,000 in termite damage or a cracked foundation is cheap insurance. Against any Australian property price today, it is a rounding error, and skipping it means flying blind.

What it does and does not cover🔗

Covered: major and minor defects, safety hazards, evidence of timber pest activity or conducive conditions, and the areas inspected plus any limitations.

Not covered: inside wall cavities, under slabs, inaccessible roof voids, pools and pool equipment, electrical and plumbing (separate trade inspections), and asbestos testing (a specialist service). Cosmetic issues like paint and carpet are not the point.

Important: a clear report means no visible evidence was found at the time, not that hidden problems are impossible. An inspector working to the standards can only report on what they can physically see and reach.

When to get one🔗

Private sale: you usually get a cooling-off period of 2 to 5 business days after signing (varies by state). Use it to inspect. If the report is bad you can pull out and lose only the cooling-off penalty (often about 0.25% of the price), far better than being stuck. Better still, make your offer subject to a satisfactory building and pest inspection.

At auction: there is no cooling-off period, so once you win and sign you are committed. Get the inspection before auction day, so a bad report means you simply do not bid. Cooling-off rules vary by state, so confirm yours and get advice from your conveyancer before signing.

How to choose a good inspector🔗

• Licensed and qualified for your state's requirements.
• Insured (professional indemnity and public liability); ask before booking.
• Follows the standards (AS 4349.1 and AS 4349.3).
• Provides a sample report that is detailed, plain-English and photo-rich, not a two-page tick-and-flick.
• Independent, not recommended by the selling agent.
• Walks you through the findings in person; that chat is often more useful than the written report.

What to do if the report finds problems🔗

A report with defects is information, not automatically a deal-breaker. Minor defects (cracked tiles, a leaky tap, worn weatherboards) are normal in older homes. Major structural issues or active termites need real thought.

Before deciding anything, get quotes from the relevant trades (a builder for structural work, a licensed pest controller for termites). Then you can renegotiate the price with real numbers, ask the vendor to fix items before settlement, or walk away. That is exactly what the cooling-off period and inspection conditions are for.

A note on termites🔗

Termites (white ants) are widespread across much of Australia, and around one in five homes is affected by termite activity, causing an estimated $1.5 billion in damage a year. The catch that blindsides buyers: termite damage is generally not covered by standard home insurance, because insurers treat it as a preventable maintenance issue.

Even a property that looks perfect can hide active termites or past damage. Conditions that attract them include moisture and poor drainage, wood-to-soil contact, mulch and garden beds piled against external walls, and leaking pipes. A clear pest report means none was found on the day, not that the home is immune, so ongoing termite management is a separate job after purchase.

The bottom line🔗

For $400 to $700, a building and pest inspection tells you whether the home you are about to spend hundreds of thousands on is structurally sound and termite-free. Book an independent inspector, time it for the cooling-off window (or before auction), and treat a bad report as leverage, not a catastrophe. It is the cheapest way to avoid the most expensive mistakes.
