What a pre purchase building inspection costs
Last reviewed
Indicative $400 to $800 for a house inspection in regional NSW and VIC, plus what the report does not cover and when to book it.
A pre purchase inspection is the cheapest insurance in the whole buying process, and the one most often skipped because the auction is on Saturday. The ranges below are indicative for regional New South Wales and Victoria. City pricing is different and so is the competition for inspectors.
Indicative costs
| Inspection | Indicative range |
|---|---|
| Standard house, pre purchase building report | $400 to $700 |
| Timber pest inspection on its own | $250 to $450 |
| Building and pest combined | $500 to $900 |
| Acreage, large or two storey homes | add $100 to $300 |
| Travel beyond the inspector's base town | add $80 to $250 |
| Structural engineer's report | $600 to $1,800 |
| Asbestos identification and sampling | $400 to $1,200 |
| Strata or owners corporation records search | $250 to $500 |
Combined building and pest is usually cheaper than booking the two separately, because it is one trip and one set of ladders. In towns like Mudgee, Bright or Deniliquin there may be only a handful of inspectors, so the travel line matters and the lead time matters more.
What the standard report actually is
A pre purchase building inspection in Australia is generally carried out to Australian Standard 4349.1, and a timber pest inspection to AS 4349.3. Both are visual and non invasive. The inspector looks at what can be safely accessed and does not cut open walls, lift fixed floor coverings or move stored goods.
That scope is why the report has a long list of areas not inspected. Subfloors too tight to enter, roof spaces with no access hatch, and anything behind a full garage of boxes will be excluded. Read that list first. It tells you what you still do not know.
The report should describe the condition of the structure, the roof, the wet areas, the drainage away from the house, and any major defect or safety hazard. It is not a valuation, it is not a compliance audit of the wiring or the plumbing, and it does not certify that past work was approved.
What it will not tell you
Three gaps catch buyers regularly.
The first is unapproved work. An inspector may note that the pergola or the enclosed carport looks like an addition, but confirming approval means checking with the council. On regional blocks, unapproved sheds, decks and second dwellings are common and they become your problem at settlement.
The second is the septic system. A building report does not assess an onsite wastewater system. If the property is unsewered, and most rural blocks in the Riverina, Ovens Murray and the Goulburn Valley are, you want that looked at separately. The rules and costs are in our septic and onsite wastewater guide.
The third is the electrical and plumbing condition beyond what is visible. An old switchboard with rewireable fuses gets a note. Whether the circuits are safe needs a licensed electrician. Ask for a quote from an electrician if the report flags the board.
Timber pests in inland NSW and Victoria
Termites are a live risk across most of inland New South Wales and northern Victoria, and it does not follow the price of the house. Older homes on stumps, houses with garden beds built up against weatherboards, and blocks with old stumps or buried timber are the usual candidates.
A pest report will note conducive conditions as well as active activity. Conducive conditions matter, because they are what turns a clean report today into damage in five years. Poor subfloor ventilation and soil levels above the damp course are the two most common findings in older regional housing and both are fixable.
If the report finds activity, get a treatment quote before you make an offer, not after. Treatment cost varies enormously with construction type. Browse pest control listings for your town.
Timing, cooling off and auctions
In New South Wales, a private treaty purchase generally carries a cooling off period of a few business days with a small forfeit if you withdraw, and there is no cooling off period on an auction purchase. Victoria also provides a short cooling off period on private sales, with a penalty, and none at auction. The exact periods and penalty amounts are set in each state's legislation and have been adjusted over time, so confirm the current position with your conveyancer or solicitor before you rely on it.
The practical consequence is the same in both states. If you are bidding at auction, the inspection has to happen before the hammer falls. Inspectors in regional towns book out one to two weeks ahead in a busy market, so ring them the day the property is listed.
Choosing the inspector
Ask who is doing the inspection and what they are qualified in. In Victoria, building inspectors are a registered class with the Victorian Building Authority. In New South Wales, pre purchase inspections are commonly done by licensed builders or by consultants who hold building licences and pest technician qualifications.
Then ask four things.
- Do you carry professional indemnity insurance, and can I see the certificate?
- Can I see a sample report from a similar property?
- Can I walk through with you at the end, or will you take my call to explain the findings?
- Do you have any relationship with the agent or the vendor?
The last one matters. The report should be commissioned by you and written for you. A report supplied by the vendor is not worthless, but you did not choose the inspector and you are not the client.
A short verbal debrief is often more useful than the document. A good inspector will tell you plainly which items are cosmetic, which are a negotiating point and which are a walk away.
Using the report
A report that finds problems is a report doing its job. Use it to price the fix, then decide whether to renegotiate, ask for the work to be completed before settlement, or withdraw.
Get real quotes for the major items rather than guessing. Start with builders in Albury or builders in Wodonga, and check any licence you are given with the licence check tool.
Questions this guide gets asked
How much does a building and pest inspection cost in regional NSW or Victoria?
An indicative range for a standard house is $500 to $900 for a combined building and pest inspection, or $400 to $700 for the building report alone. Acreage, two storey homes and travel outside the inspector's base town add to that. Ranges are indicative and vary by town and inspector.
Does a building inspection cover the septic system?
No. A standard pre purchase inspection under AS 4349.1 does not assess onsite wastewater systems. If the property is unsewered, arrange a separate inspection of the tank, the treatment unit and the land application area. A failing system is one of the most expensive surprises on a rural block.
Can I get an inspection before an auction?
Yes, and you must, because auction purchases carry no cooling off period in either state. Book as soon as the property is listed, since regional inspectors are often a week or two ahead. Arrange access through the agent for the same time as an open inspection if the vendor prefers.
What does the inspector not look at?
Anything not safely accessible or visible, including areas behind walls, under fixed floor coverings, inside inaccessible subfloors and roof spaces, and behind stored goods. Every report lists these exclusions. Read that section first, because it defines what the report cannot tell you.
Should I use the report the agent gives me?
Treat it as background, not as your own advice. You did not choose the inspector, and the report was commissioned by someone whose interest is the sale. Commission your own inspection if the purchase matters, and ask the inspector directly whether they have any relationship with the agent or vendor.
Is a defect report the same as a pre purchase inspection?
No. A pre purchase inspection gives a general overview of the property's condition to a standard scope. A defect report investigates a specific problem, such as cracking or water ingress, and often needs a structural engineer. If the pre purchase report flags something serious, the engineer's report is the next step.
