Building and Pest Inspection Checklist Australia: Timing, Scope and Report Limits

Short answer

A pre-purchase building report records visible defects and the condition of accessible building areas. A timber-pest report checks for activity, damage and conditions that may increase pest risk. They are different scopes, even when one provider completes both.

Order the reports early enough to read them, ask questions and arrange any specialist follow-up before the purchase becomes unconditional. For an auction, that usually means before auction day. For a private sale, ask the conveyancer to explain the contract, inspection condition and cooling-off timetable before signing.

Add an editable allowance in the Property Purchase Cost Calculator, then replace it with current written quotes. There is no reliable national fixed price because property size, location, access, report scope and provider qualifications vary.

Building report and timber-pest report are not the same

A building report generally focuses on the condition of the building and visible defects in accessible areas. Depending on the agreed scope, it may record items such as cracking, damp, roof defects, safety hazards, movement or deterioration.

A timber-pest inspection looks for evidence of termites and other timber-destroying pests, damage and conditions that may increase risk.

NSW Government guidance says a building report may identify visible termite damage but does not establish whether termites or other timber-destroying pests remain active. It recommends a separate pest inspection, especially where termites are a known risk.

Ask the provider to state:

• whether the quote is for building only, timber pests only or both;
• who performs each part;
• which licence or qualification applies in the state;
• which areas will be inspected;
• which areas may be inaccessible;
• whether moisture testing or other equipment is included; and
• whether a verbal briefing is available after the written report.

Timing for private treaty

Do not assume every state has the same cooling-off rights or contract process.

Before signing:

1. Ask the agent how access for inspectors is arranged.
2. Ask the inspector how much notice and report turnaround they need.
3. Give the contract to a solicitor or conveyancer.
4. Ask how an inspection condition should be drafted and exercised.
5. Leave time for follow-up by an engineer, electrician, plumber, surveyor or other specialist if the report recommends it.

Moneysmart says a conditional offer can depend on matters such as finance, valuation or inspections. The wording and legal effect depend on the contract and jurisdiction, so use a licensed conveyancer or solicitor rather than copying a generic clause.

Timing before an auction

Auction sales are generally unconditional and do not carry the usual cooling-off period. Moneysmart says a sale at auction is final and is not subject to finance or a building or pest inspection.

That changes the sequence:

1. Check the likely price range before spending on reports.
2. Obtain the contract and legal review.
3. Arrange building, pest and any relevant strata reports.
4. Read the reports and ask the inspector about major findings.
5. Price further investigations into the pre-auction budget.
6. Decide a bid limit without assuming defects will be renegotiated after the auction.

The Auction Bidding Budget Checklist covers the other costs and checks that sit around this step.

What to check in the quote

Use this list before booking:

• property address and property type;
• building-only, pest-only or combined scope;
• inspector name and relevant licence or qualification;
• professional indemnity insurance;
• areas included, such as roof space, roof exterior, subfloor, outbuildings and site;
• access requirements and exclusions;
• equipment included;
• report delivery time;
• whether photographs are included;
• whether major and minor defects are separated;
• whether likely repair costs are included or require a special-purpose report;
• whether you can speak with the inspector;
• total fee, cancellation terms and any reinspection fee; and
• whether the report is prepared for you and whether you may rely on it.

NSW Government guidance says the written report should identify the scope, areas not inspected and reasons, overall condition, major faults and recommendations for specialist follow-up where needed.

What a standard report may not tell you

A pre-purchase report is not a warranty against future defects. It is also not automatically:

• a structural engineering report;
• a pest report;
• an electrical compliance check;
• a plumbing or sewer inspection;
• asbestos sampling;
• a survey of boundaries or encroachments;
• a council approval search;
• an estimate of repair cost;
• a strata records inspection; or
• legal advice on the contract.

The report can only cover accessible areas within its stated scope. Stored goods, floor coverings, wall linings, height, locked areas, weather and safety conditions may limit access.

If an exclusion matters to the purchase, ask what separate investigation is suitable and whether the contract timetable allows it.

Apartments and strata properties

A building inspection and a strata records report answer different questions.

The building inspection is a physical check of the lot and accessible building areas within scope. A strata or owners corporation report can show financial records, insurance, planned works, meeting minutes, defect disputes and special levies.

For an apartment, unit or strata townhouse, ask the conveyancer which records search applies in that jurisdiction. Do not treat a clean inspection inside the lot as proof that the building has no common-property defects or funding issues.

Illustrative example

A buyer is considering a 1980s townhouse scheduled for auction on Saturday.

The combined inspection booked on Monday cannot access part of the roof space. The report records elevated moisture near one bathroom wall and recommends a specialist plumbing check. The owners corporation records also show discussion of balcony waterproofing.

The reports do not prove the cause, provide a complete repair price or determine the maximum bid. They do give the buyer four concrete tasks before Saturday:

1. ask why the roof space was inaccessible;
2. arrange the recommended plumbing check if access and time permit;
3. have the conveyancer review the owners corporation records and contract; and
4. keep an allowance for unresolved work inside the bid budget.

This is an illustrative process, not a defect diagnosis or purchasing recommendation.

Common mistakes

Treating a building report as a pest report

Ask for both scopes in writing. Visible old damage is not the same question as active timber-pest risk.

Ordering after the decision point

A detailed report has limited value if the contract is already unconditional and there is no remaining right to act on it.

Assuming a low quote covers the same work

Compare access, scope, qualifications, insurance, turnaround and follow-up, not only price.

Treating repair estimates as fixed quotes

A report may identify an issue without opening walls, testing materials or measuring the full extent. Obtain trade or specialist quotes where the decision depends on cost.

Ignoring report exclusions

Read every area marked inaccessible or outside scope. The limitation may be more important than the visible defect list.
