Building and pest inspection cost

How long you have to inspect and still walk away in your state, and the inspection fee set against the price.

Your deadline

Time to inspect and still pull out

5 business days

On a private-treaty purchase in New South Wales, counted from when the contract is made. Inspection quotes: $600, 0.08% of a $750,000 purchase.

When the inspection has to happen — New South Wales, private treaty

5 business days, counted from when the contract is made; the window closes at 5 pm on the fifth business day after the day it starts. Walking away costs 0.25% of the price, taken from the deposit. At auction, there is none — and none either where the contract is made the same day the property was passed in. Ten business days instead of five for an off-the-plan contract.

The deadline matters more than the fee

Inspection fees are quotes, not schedules, so this page invents no average. What matters more than the price is the deadline: on most purchases the window in which an inspection can still save you is measured in business days, and at auction it closes before you raise your hand.

The price is the obvious thing to compare. The more expensive mistake is booking one too late, because the protection an inspection offers only exists while you can still withdraw.

At auction there is generally no cooling-off period. The moment the hammer falls you are contractually bound, so an inspection has to be arranged and read before you bid — on a property you may not win. That is money at risk, and a bidder can end up paying for inspections on more than one property.

By private treaty you may get a short statutory window. In New South Wales the cooling-off period ends at 5 pm on the fifth business day after the contract is made, or the tenth business day for an off-the-plan contract, and withdrawing forfeits 0.25% of the purchase price to the vendor. Queensland has its own cooling-off period under the Property Occupations Act. The durations, the penalties and the exclusions differ by state, and some jurisdictions provide none at all, so confirm your own before you rely on it.

And the window can be signed away. In New South Wales a buyer can shorten or waive cooling off with a certificate under section 66W of the Conveyancing Act 1919; Queensland allows waiving or shortening under section 167 of its Act. A vendor may ask for one; signing it converts your inspection from a safety net into a formality — so do the inspection first.

What the fee actually buys

A building inspection is a visual inspection of accessible areas: structure, roof void, subfloor, wet areas, drainage, visible defects. Nothing is opened up, so anything behind a wall, under a floor covering or inside a sealed cavity is outside its scope by definition. A pest inspection is a separate exercise looking for termites and other timber pests, and for the damp and timber contact that invites them.

Two things it is not. It is not a valuation — it says nothing about what the property is worth. And it is not a warranty; an inspector reports what was visible on the day, which is why the report’s list of inaccessible areas deserves as much attention as its list of defects.

Small in proportion, and the only one that can stop you

Set against the price, the fee is small. On the default figures above it is 0.08% of the purchase price. Every other cost in a purchase buys you the property. This is the only one that can tell you not to buy it.

If you want the full settlement-day picture rather than this one line of it, the upfront costs calculator totals duty, registry fees, LMI and these quotes together.

Frequently asked questions

How much does a building and pest inspection cost?

It is a market price with no schedule behind it, so any figure quoted as a national average is someone's estimate rather than a published rate. What is worth knowing is the shape of the quote: building and pest are two different inspections, and they may be quoted together or separately. Get two or three quotes, check what each one actually includes, and compare them on the tool above.

When do I need to book the inspection?

Before you are locked in. At auction there is generally no cooling-off period at all, so the inspection has to happen before you bid. On a private-treaty purchase you may have a short statutory cooling-off period, but it is measured in business days rather than weeks. In New South Wales it ends at 5 pm on the fifth business day after the contract is made, and ten business days for an off-the-plan contract.

Can the cooling-off period be shortened?

In some states, yes. In New South Wales a purchaser can waive or shorten it by giving a certificate under section 66W of the Conveyancing Act 1919, and a vendor may ask for one before agreeing to a sale. Queensland allows the period to be waived or shortened too, under section 167 of the Property Occupations Act 2014. If you sign one of those, the window in which an inspection could save you disappears — so do the inspection first.

What does a building inspection actually cover?

A visual inspection of what the inspector can safely reach: structure, roof void, subfloor, walls, wet areas, drainage and visible defects. It is not destructive, so it does not include anything behind a wall, under a floor covering or inside a sealed cavity. A pest inspection looks specifically for termites and other timber pests and the conditions that attract them. Neither is a warranty, and neither values the property.

Is a building and pest inspection worth it?

On the numbers, it is small. On example quotes totalling $600, a $750,000 purchase pays 0.08% of the price for the only part of the process that can tell you not to proceed. Put your own quotes and price into the tool above to see the proportion for your purchase.

Do I need one for an apartment?

A standard building inspection covers the lot you are buying, not the whole block, and much of what matters in an apartment is common property maintained by the scheme. For a unit, the strata records are usually more revealing than an inspection of the lot itself — the minutes, the maintenance plan and the capital works balance tell you what is coming. Our strata fees page explains what to look for.
