Building and Pest Inspection Cost in Australia (2026): Prices by City and Property Type

Marketing shows a home at its best. A building and pest inspection is your independent look at the property’s condition, commissioned by you, before you sign an unconditional contract or bid at auction.

How much does a building and pest inspection cost?

A combined building and pest inspection on a standard three or four bedroom house costs $330 to $1,090 including GST across the eight capital cities, and $495 to $750 in Sydney, Melbourne and Brisbane. The table below gives each city by property type. Every figure is a price an inspector or a dated price guide publishes; the source for each row is listed at the end of the page.

Combined building and pest inspection, GST included. Unit: unit or apartment. 1–2 bed: townhouse or one to two bedroom house. 3–4 bed: three to four bedroom house. Large: five or more bedrooms, multi-storey, older or rural. A plus sign means the top figure is a “from” price with no published ceiling. An asterisk means only one named source publishes that figure. Read 30 September 2026.

Combined vs building-only vs pest-only

Most inspectors price the combined inspection as the default and the two halves as separate products. Where a source publishes the split, the table shows it; where the sources for a city price only the combined inspection, the cell says so.

• Sydney. Only iSPECT publishes building-only and pest-only prices for Sydney; Rapid and Pest & Building Inspections price the combined inspection only.
• Melbourne. No Melbourne source read publishes a pest-only price; Inscope says adding the pest inspection to a building inspection costs $100 to $200.
• Brisbane. Only iSPECT publishes a pest-only price for Brisbane. Rapid prices an older character home at $750 to $900 or more.
• Perth. Perth has the widest published spread: a fixed-price operator at $549 and a premium firm at $790 to $1,090 for the same combined inspection.
• Adelaide. No Adelaide source splits the combined price by bedrooms: A E & J charges $638 for a house or a unit, and the guides give one range each. Pre-1990 homes add $50 to $150 (Pest Inspections Adelaide).
• Hobart. Only iSPECT publishes a combined price for Hobart. The two local firms price building inspections only: Swell includes a visual pest check in its building inspection and Hobart Building Inspection publishes no pest price.
• Canberra. Only iSPECT prices a Canberra unit or small home. The seller commissions the building, compliance and pest reports before listing and the buyer reimburses them at completion, so most Canberra price lists are vendor packages: ACTBIS $1,790 and My Canberra $1,697 plus GST for building, pest, compliance and energy rating.
• Darwin. Darwin's local firm prices a plan, not a property type: $775 for building and pest, $2,175 with plumbing and electrical. The national operators price by bedrooms.

Book the combined inspection unless cost is a real constraint. The defects that attract termites (moisture, timber-to-soil contact, blocked subfloor ventilation) are the same ones a building inspector writes up, and one visit is cheaper than two: Pest Inspections Adelaide puts the saving at $30 to $80 (2026), and Inscope says adding the pest inspection to a Melbourne building inspection costs $100 to $200 (2026).

What changes the price

• Bedrooms and storeys. iSPECT prices by bedroom count: $465 plus GST for a one to two bedroom house rising to $515 for five or more bedrooms in Sydney, Melbourne, Hobart, Canberra and Darwin, and $490 to $590 in Brisbane. Swell in Hobart runs from $550 for a one bedroom unit to $968 for a five bedroom, three bathroom house (18 May 2026).
• Age and construction. Older homes take longer and produce longer reports: Pest Inspections Adelaide adds $50 to $150 for pre-1990 homes and more for stone or double-brick character homes; Rapid prices an older Brisbane character home at $750 to $900 or more against $550 to $750 for a standard house (12 August 2026).
• Access. A roof void and a subfloor the inspector can enter cost nothing extra; ones they cannot get into are listed as “not inspected” and are the risk you carry.
• Location. Metro prices are base prices. Rapid (Adelaide), Point and Inscope (Melbourne) all say properties outside the metro area can attract a travel fee, and WA Building Inspections charges $89 plus GST per hour of additional travel.
• Urgency. Point Building Inspections adds $50 to $150 for priority or 24-hour turnaround in Melbourne (2026). Auction week is the expensive time to book.
• Extras. Thermal imaging, drone roof photography, drug-residue testing, pool and asbestos checks are priced separately: WA Building Inspections charges $799 plus GST for its thermographic package against $499 for the standard one, and Point quotes $200 to $500 for an asbestos or pool add-on.

Hidden fees to ask about

The price pages agree on what to check before you accept a quote. Ask, in writing:

• Is GST included? iSPECT, WA Building Inspections, APBI and My Canberra all quote ex GST; add 10%. Inspect My Home, Swell and QLD Build Check quote GST inclusive.
• Are sheds, granny flats and outbuildings included? WA Building Inspections charges $89 plus GST for each auxiliary dwelling or shed.
• Are common areas included for an apartment? Rapid notes that adding common areas to an apartment inspection costs extra.
• Does the roof void and subfloor get entered, or viewed from the hatch? BuyWise’s checklist lists roof and subfloor access, moisture testing, thermal imaging and photography as the items to confirm.
• Is there a travel fee, and from where? Most metro quotes hold inside a set radius; My Canberra includes travel within 30 minutes of Canberra and confirms any extra before booking.
• What is the report turnaround, and is a phone debrief included? iSPECT, Inspect My Home, QLD Build Check and Pest & Building Inspections all promise the report within 24 hours; a same-day rush may cost more.

Who pays for the inspection

In New South Wales, Victoria, Queensland, Western Australia, South Australia, Tasmania and the Northern Territory the buyer commissions and pays for the inspection, because it is for the buyer’s benefit and an inspector chosen and paid by the seller is not independent. Three points of difference:

• Queensland. The REIQ standard contract’s building and pest condition puts the inspection on the buyer, who organises it with licensed inspectors and bears the cost (Statewide Legal, 10 September 2018), then tells the seller by the contract date whether the reports are satisfactory. The contractual remedy is termination, acting reasonably; a price cut is a negotiation, not a right (Preston Law, 13 November 2024). The building inspector must hold a QBCC licence (Queensland Government, Inspections, 22 August 2024).
• The ACT. The seller must have a building and compliance inspection report and a pest inspection report, each no more than three months old, in the contract before the property is listed, and the buyer reimburses their cost at completion, not including any premium the seller paid for a faster turnaround (Civil Law (Sale of Residential Property) Act 2003 (ACT), sections 9 and 18). That is why Canberra inspectors sell vendor packages: ACTBIS at $1,790 and My Canberra at $1,697 plus GST for building, pest, compliance and energy rating reports.
• Victoria. On 12 March 2026 the Premier announced a mandatory building and pest inspection scheme under which sellers would commission the reports before sale, make them available to every prospective buyer and recover the cost from the successful purchaser, modelled partly on the ACT, with legislation to be introduced in 2027 if the government is re-elected. Until then the buyer pays.

Strata buyers pay twice: a strata records inspection ($350 to $450 in New South Wales, Westla, 2026) covers the scheme’s finances, levies and defect history, which a building inspection does not.

Why you need a building and pest inspection

When purchasing property in Australia, you have limited rights to seek remedies after settlement for defects you could have discovered beforehand. The principle of caveat emptor (buyer beware) means the burden is on you to investigate the property’s condition before signing an unconditional contract.

A professional building and pest inspection commissioned before exchange gives you:

• Full disclosure of the property’s condition from a qualified professional, not just what’s visible to the naked eye.
• Negotiating power. If significant defects are found, you can ask for a price reduction or require the vendor to fix them before settlement.
• Walk-away rights. In a private sale with a building inspection condition, you can withdraw from the purchase if major defects are found.
• Future maintenance planning. Even if all issues are minor, the report helps you understand what maintenance to budget for.

What’s inspected

A standard combined building and pest inspection in Australia covers:

Building inspection

• Roof (tiles, gutters, flashings, penetrations)
• Roof space (structure, insulation, ventilation)
• Subfloor area (drainage, moisture, structure)
• External walls (cladding, rendering, cracks)
• Internal walls and ceilings (cracks, water damage, stains)
• Floors (bounce, squeaks, levelness)
• Windows and doors (operation, sealing, frames)
• Wet areas (bathrooms, laundry, kitchen) for waterproofing and drainage
• Garage and outbuildings
• Visible drainage and stormwater
• Retaining walls and fencing

Pest inspection

• Termite activity (live termites, past activity, damage)
• Termite conducive conditions (timber-to-soil contact, excessive moisture)
• Timber borers
• Evidence of other pests (rodents, wood decay fungus)

Note: inspectors can only assess what is accessible and visible. A building inspection is not a structural engineering report or a compliance inspection, it identifies visible defects and issues, not hidden structural faults (unless there are visual indicators).

Inspectors generally do not test individual electrical outlets, gas appliances, or plumbing fixtures (beyond a visual check). A separate electrical or plumbing inspection may be warranted for older properties.

Common issues found

Experienced inspectors find something in almost every property they inspect, the question is severity.

High severity (deal-breakers or major price negotiation)

• Active termite infestation. Termites can cause extensive structural damage, particularly to timber-framed homes. Active infestations require immediate professional treatment and can require significant structural repairs.
• Rising damp. Moisture wicking up through walls from the ground, often caused by failed damp-proof courses. Can cause structural damage, mould, and health issues. Repairs can cost $5,000 to $30,000+.
• Major structural cracks. Diagonal or step cracking through external masonry walls, particularly around windows and door frames, can indicate foundation movement. May require a structural engineer’s assessment.
• Significant roof damage. Failed flashings, cracked tiles, or deteriorated roofing membranes that require full replacement. Roof replacements can cost $10,000 to $30,000+.
• Subfloor drainage issues. Poor drainage allowing water pooling under the house, which promotes termite activity and timber decay.

Moderate (maintenance items to budget for)

• Cracked or missing roof tiles
• Blocked or poorly graded gutters and downpipes
• Failed bathroom waterproofing (common in older properties)
• Termite conducive conditions (but no active infestation)
• Deteriorated external paint and caulking
• Substandard electrical (older switchboards, surface-mounted wiring)
• Retaining walls showing signs of movement

Minor (normal wear and tear)

• Sticking doors and windows
• Hairline cracks in plasterboard walls
• Worn or damaged floor coverings
• Minor external paint deterioration

Who to hire

Look for an inspector with the following qualifications:

• Building inspector. Should be a licensed builder, architect, or engineer with inspection qualifications. Check that licence on your state’s register, and ask for a report to Australian Standard AS 4349.1. In Queensland only a QBCC-licensed residential building inspector can do a pre-purchase inspection.
• Pest inspector. Should be a licensed pest controller or timber pest inspector, qualified under Australian Standard AS 4349.3.
• Professional indemnity insurance. Essential. If the inspector misses a significant issue, you need recourse.

Try to attend the inspection in person. A good inspector will walk you through the property and explain findings in plain English, far more valuable than reading a report alone.

When to get the inspection

• Private sale with conditions. The inspection clause in your contract gives you a set timeframe to commission the inspection and, if issues are found, to either withdraw or renegotiate. Read the date in your contract, not a rule of thumb.
• Before auction. Must be done before auction day. Contact the selling agent to arrange access. Allow at least 48 to 72 hours turnaround to receive the report.
• Before making an offer (preferred). Some buyers commission inspections before making an offer to negotiate with full knowledge. This means paying for an inspection on properties you may not buy, but avoids conditional delays.

How to read the report

Building and pest reports follow a standard format (typically AS 4349.1 for building and AS 4349.3 for pests). Key sections to focus on:

1. Summary / overview. This section gives the inspector’s overall assessment. Read this first, does the inspector flag any “major defects” or “safety hazards”?
2. Major defects. These are defects that require significant remediation. A major defect in the report is different from minor maintenance items.
3. Pest activity. Any active termite evidence, past termite damage, or conducive conditions. Note: past termite activity (treated and resolved) is less concerning than active infestation.
4. Photographs. Good reports include photos of all significant findings. Review these carefully, a crack in a photo often communicates more than a paragraph of text.
5. Items not inspected. Reports must disclose what could not be accessed. Unexplored areas (e.g. concealed roof void, locked rooms) are risk areas.

Not all defects are created equal. A report listing 15 minor items is very different from one listing 3 major defects. If in doubt, call the inspector directly and ask them to explain the severity and estimated cost of remediation.

Negotiating after an inspection

If the inspection reveals significant issues, you have several options:

1. Withdraw from the purchase (if within your inspection condition timeframe). You are entitled to a refund of the deposit.
2. Negotiate a price reduction. Get quotes for the identified repairs and ask the vendor to reduce the price by that amount. Be specific, quote the estimated cost and attach the relevant section of the report.
3. Ask the vendor to fix it. For some issues (particularly safety hazards), you can request the vendor rectify the defect before settlement. Less common, most vendors prefer to reduce the price than arrange repairs.
4. Accept and proceed. If defects are minor and the price already reflects the condition, you may choose to proceed without negotiation.

When negotiating based on inspection findings:

• Get repair quotes from licensed tradespeople (not verbal estimates)
• Be reasonable, all properties have some defects
• Focus on major defects, not minor wear and tear
• Negotiate through your conveyancer (or your buyer’s agent, if you have one), in writing

Inspections for new homes

Many buyers assume new homes don’t need an inspection. This is a mistake. Common issues found in new construction include:

• Incomplete waterproofing or substandard bathroom tiling
• Drainage issues not visible at ground level
• Structural cracks in brickwork from settling
• Substandard insulation or missing insulation
• Defects in electrical or plumbing that didn’t pass handover inspection

For new homes, consider engaging a pre-handover inspector who attends the builder’s handover inspection with you. Any defects identified can be included in a defects list that the builder must rectify before you take possession. Handover inspections are priced separately from pre-purchase ones: iSPECT charges $465 to $525 plus GST by bedroom count and WA Building Inspections $499 plus GST.

New homes come with statutory warranties, but the periods vary by state: in NSW, 6 years for major defects and 2 years for other defects; in Victoria, up to 10 years from completion. Check the periods that apply with your state’s building regulator. Document any issues with photos and written notices to the builder. See our complete buying guide for the broader process.
