A combined building and pest inspection for a standard Australian house costs between $400 and $1,000, depending on property size, location and urgency. For a 3-bedroom home, expect to pay $550 to $850. For a 2-bedroom apartment, $450 to $700.
That is the cost. Here is the context: 1 in 4 Australian homes show signs of termite activity, and average termite damage repairs run $7,000 to $30,000. The inspection is the single cheapest point in a property purchase to catch problems that cost tens of thousands to fix.
Building and Pest Inspection Cost by Property Size
Prices vary primarily by how much ground the inspector has to cover. These are combined building and pest inspection estimates for 2025:
| Property type | Combined building and pest inspection cost |
|---|---|
| Apartment (up to 2 bed) | $450 – $700 |
| Standard house (3 bed, 1 bath) | $550 – $850 |
| Large house (4–5 bed, 2+ bath) | $750 – $1,100 |
| Very large or acreage property | $1,100+ |
For a real-world reference, Queensland-based iSPECT lists fixed prices from $465+GST for a 1–2 bedroom house up to $515+GST for 5+ bedrooms, with apartment building-only inspections starting at $395+GST. Those prices include travel costs, and reports are delivered within 24 hours.
Capital city properties in Sydney, Melbourne, Brisbane, Perth and Adelaide sit at the top of these ranges due to higher insurance, salary and operating costs for inspection firms.
Building-Only vs Combined: What Is the Price Difference?
A building-only inspection costs $300 to $600. It covers structural condition but skips timber pests entirely.
A combined building and pest inspection costs $450 to $900 and assesses both the structure and timber pests (termites, borers) along with the conditions that attract them. Ordering the two as separate inspections from different providers costs more than a combined service.
Given that termite damage alone averages $7,000 to $30,000 in repairs, spending the extra $150 to $300 for the pest component is straightforward maths. The combined inspection is standard practice for good reason.
What Pushes the Price Up or Down
Beyond property size, several factors move the building and pest inspection cost in either direction.
Property age and complexity. Older homes (pre-1980 builds), properties with extensions or renovations, sloping blocks, and difficult roof access all extend inspection time and can push the fee higher.
Location. Capital city inspectors carry higher overheads. Regional markets tend to sit at the lower end of each price band.
Technology. Inspectors who use drones, moisture metres and thermal imaging cameras commonly include the cost of these tools in their charges. This adds to the fee but produces a more thorough report.
Urgency. Same-day reports cost extra. In Sydney and NSW, where cooling-off periods are shorter and auction conditions more common, same-day or 24-hour turnarounds are often essential.
What the Inspection Covers, and What It Does Not
A standard building and pest inspection report should cover:
- Interior and exterior walls
- Roof exterior and roof cavity
- Gutters
- Floor and subfloor
- Toilets, bathrooms and laundry
- Garage, sheds, driveways and carports
- Stairs, fencing and pathways
- Non-structural retaining walls
- Visible structural issues and minor defects
- Visible signs of asbestos and termite infestations or damage
What the report will not do: it will not estimate repair costs or advise whether a property is worth buying. It also will not assess areas that are inaccessible or concealed within the property. The inspector documents what they can see and access. Anything behind walls, under fixed flooring, or in sealed cavities falls outside the scope.
This is an important limitation for investment buyers. The report tells you what is wrong. It does not tell you what it will cost to fix or whether the numbers still work. That assessment is yours to make.
How Long Does the Inspection Take?
On-site inspection times vary by property type:
| Property type | Time on site |
|---|---|
| Apartments | 1.5 – 2.5 hours |
| Townhouses / villas | 2 – 3 hours |
| Standalone houses | 3 – 4+ hours |
After the on-site visit, most inspectors deliver the report within 24 to 48 hours. Some firms offer same-day turnarounds for an additional fee.
If an inspector is quoting 90 minutes to 2 hours for a full house, that is a warning sign. A thorough inspection of a standard house takes 3 to 4 hours. Corners get cut when time gets compressed.
Why the Inspection Fee Is Your Cheapest Protection
The numbers make the case plainly.
Building inspections save buyers an average of $12,000 in hidden repair costs. Professional inspections identify 89% of property defects. And with 1 in 4 Australian homes showing termite activity, the pest component is not a precaution for unlikely scenarios.
One inspection firm recounts a case where a thorough inspection flagged active termite damage in the subfloor. The buyer walked away. The next buyer, who purchased without inspecting, inherited a $60,000 repair bill.
A $500 to $900 inspection versus a $60,000 repair. That ratio is the entire argument for never skipping this step, and never choosing an inspector on price alone.
The Building and Pest Clause in Your Contract
Most property purchase contracts include a building and pest clause. A correctly worded clause may give you the right to withdraw from the contract if the report is unsatisfactory.
This is the mechanism that makes the inspection actionable. Without it, you have information but no leverage. With it, you can renegotiate the price, request repairs, or walk away entirely.
At auction, there is no cooling-off period and no subject-to-inspection clause. If you are bidding at auction, arrange the inspection before auction day. The cost is the same. The difference is that you carry the risk if you skip it.
What Happens After: Specialist Reports
When the building and pest inspection flags a specific issue, the inspector may recommend follow-up specialist assessments. These include electrical checks, plumbing scopes, pool inspections, or structural engineering reports.
Each specialist report costs $200 to $1,000+ depending on the scope. Not every inspection triggers these. But when the initial report flags something like significant cracking, active moisture ingress, or outdated wiring, the specialist report quantifies the problem and gives you a repair estimate the standard inspection deliberately does not provide.
How to Choose an Inspector
The cheapest quote is rarely the best value. Here is what to look for.
Standards compliance. Inspections should be conducted in line with Australian Standards AS 4349.1 and AS 4349.3. Reports produced under these standards must document defects clearly and include photographic evidence.
Insurance. A licensed, fully insured inspector protects you if something is missed. Ask for proof of professional indemnity insurance before booking.
Time on site. A 90-minute inspection of a 3-bedroom house is not enough. If the inspector is not spending 3 to 4 hours on a standard home, they are not checking everything the standards require.
Fixed pricing. Some firms publish fixed prices that include travel costs, removing any ambiguity about what you will pay. This is preferable to vague “from $X” quotes that climb on the day.
For investment properties, the inspection is one of several pre-purchase costs to budget for alongside conveyancing, loan application fees and stamp duty.

FAQ
Is a building and pest inspection worth it?
Building inspections save buyers an average of $12,000 in hidden repair costs, and 89% of property defects are identified through professional inspections. With 1 in 4 Australian homes showing signs of termite activity and average termite repairs costing $7,000 to $30,000, the $450 to $900 fee pays for itself many times over.
How long does a building and pest inspection take?
A standard inspection takes 2 to 4 hours on site for a standalone house, with apartments taking 1.5 to 2.5 hours. Reports are typically delivered within 24 to 48 hours, with same-day options available in some markets for an additional fee.
Do I need a building and pest inspection before auction?
Yes. At auction, there is no cooling-off period and no subject-to-inspection clause. If you want the protection a building and pest clause provides in a private sale, you need to arrange the inspection before auction day.
What doesn't a building inspection cover?
A building inspection report will not estimate repair costs or advise whether the property is worth buying. It covers only visually accessible areas. Anything behind walls, under fixed flooring, or in sealed cavities is outside scope.
