Building and Pest Inspection Sydney: Cost, What's Checked, and How It Works

Building and pest inspection is a visual assessment of a property carried out to check for structural defects, safety hazards, and timber pests such as termites. A combined report is prepared according to Australian Standard AS 4349.1 so that you know the true condition of a home before you commit.

How much does a building and pest inspection cost in Sydney?

A combined building and pest inspection in Sydney typically costs between $400 and $700. The price varies based on the property size, age, and type, with units costing less and large multi-storey houses costing more.

Combining the building and pest inspections in one visit is more affordable than scheduling them separately. The pest inspection usually adds just $30 to $100 to the cost of a building inspection alone.

What does a building and pest inspection include?

The inspection consists of two main parts: a building inspection to assess the property's structure and condition, along with a pest inspection to check for termites and other timber pests. You will receive a single report that covers both inspections.

The inspector examines all areas of the property that are easy to access. This includes areas of the house that can be safely accessed without the need to cut through walls or move heavy objects.

Areas the inspector checks

• Interior: walls, ceilings, floors, windows, doors, and wet areas like bathrooms and laundries.

• Roof space: the roof void and framing, checked for leaks, sagging, and pest activity.

• Subfloor: the under-floor area, footings, and stumps where accessible.

• Exterior: external walls, gutters, eaves, decks, and weep holes.

• Roof exterior: gutters and downpipes, subject to height and safety limits.

• Site: fencing, retaining walls, driveways, paths, and surface drainage.

Building-only or combined building and pest: which do you need?

For most property purchases in Sydney, a combined building and pest inspection is the better option. A building-only inspection is suitable in limited situations, but skipping the pest check can be risky in areas prone to termites.

Opt for a combined inspection when buying a standalone house, townhouse, or any property with wooden structures, decks, fences, or gardens, which applies to most homes. A building-only inspection is appropriate for properties with minimal accessible timber and low termite risk, like a high-floor apartment in a concrete building, where a pest inspection may not be necessary. If unsure, it's best to get both: the pest inspection typically costs an additional $30 to $100.

What does the pest inspection look for?

The pest inspection checks for wood pests, especially termites, and the factors that attract them. It looks for current infestations, previous damage, wood borers, and signs of decay or rot.

Termites are attracted to moisture, so inspectors use moisture meters and thermal imaging to find activity behind walls. They also identify conditions that could lead to infestations, such as wood touching the ground, poor drainage, or wet subfloors.

This is important because termite damage is often not covered by home insurance and can be very expensive to fix. The goal is to identify issues before you purchase the property.

During inspections in Sydney, our inspector Emjay often finds that the biggest problems are not just active termites but the conditions that allow them to thrive: wet subfloors, wood stored against outside walls, and garden beds over weep holes. Addressing these issues early can help prevent infestations.

What is AS 4349.1 and why does it matter?

AS 4349.1 is the standard used in Australia for property inspections. A report based on this standard ensures that the inspection follows a consistent process instead of the inspector's personal preferences.

This standard outlines what needs to be checked and how to note any limitations but doesn’t specify how the report should look or how much it should cost. When you schedule an inspection, make sure it’s done according to AS 4349.1 so you can compare quotes accurately.

What is not included in the report?

A building and pest inspection looks for major visible issues but does not guarantee that the property is free of faults. Some areas are not included in the inspection.

Typically, the report does not address minor cosmetic issues, repair costs, or hard-to-access areas. It also usually does not include specialized checks unless you ask for them.

• Hidden plumbing, drainage, and electrical wiring behind walls.

• Swimming pools and their safety compliance.

• Asbestos testing, unless specifically requested (common in homes built before 1990).

• Anything obscured by furniture or stored items.

If the report mentions a limitation, it means that area wasn't fully checked. If there are serious concerns, the report should suggest getting a specialist to assess the issue further.

How long does it take, and when will I get the report?

The on-site inspection usually lasts between 1 and 3 hours, depending on the property size and accessibility. Hamacon Building Inspections in Sydney provide the written report within 24 hours, and same-day reports can often be arranged for urgent cases.

Since reports are completed quickly, the main delay is often in booking. Inspectors typically require two to three days' notice, so it's best to schedule the inspection as soon as the property is on your shortlist.

Who should get a building and pest inspection?

Before exchanging contracts, anyone buying a property should get an inspection. It provides a clear, independent view of what you're purchasing.

• Buyers: Discover hidden issues and avoid unexpected costs after settlement.

• Sellers: A pre-sale inspection allows you to address problems before listing, enhancing buyer confidence.

• Unit buyers: Standard inspections only cover your unit's interior and immediate exterior. You also need a strata report for shared areas like the roof and grounds, checking the sinking fund and any planned repairs.

• New-home buyers: New constructions require multiple inspections at different stages: pre-slab, frame, lockup, and final handover. Each stage ensures the builder meets Australian standards before you approve and pay.

How to choose a building and pest inspector

Select a licensed and insured inspector who follows AS 4349.1. In NSW, not all building inspectors need a license, so verifying their credentials helps you avoid a low-quality report. Hama Con Building Inspections (based in Sydney, NSW) is fully licensed and insured.

Before booking, check these four points:

• Qualifications: Look for a licensed builder, surveyor, or qualified inspector, preferably with pest accreditation.

• Insurance: Ensure they have professional indemnity insurance for protection against missed major defects.

• Sample report: A reliable inspector should provide a sample report upon request, allowing you to review details and photos.

• Independence: Choose an inspector who works for you, not one recommended by the selling agent.

It is always beneficial to have a background in construction. With his expertise in construction, an inspector like Emjay can easily differentiate between structural and cosmetic flaws and calculate the cost of repairs to provide you with the crucial information you need to make your choice.

What to do after you get the report

As your decisions are time-sensitive, review the report as soon as it arrives. Begin with the summary and major issues, then decide to either proceed, negotiate, or withdraw.

After receiving the report, you typically have four options:

• Proceed: If only minor issues are found, continue with the purchase.

• Negotiate: Use major defects to request a price reduction.

• Request repairs: Ask the seller to fix issues before finalizing the sale.

• Withdraw: If the risks are too high, back out during the cooling-off period.

If the report suggests getting a specialist, like a structural engineer or pest expert, arrange it quickly to act before contracts are finalized.

How the report helps you negotiate

A building and pest report helps you negotiate better. It identifies issues, allowing you to negotiate a lower price, request repairs before purchasing, or decide not to proceed if the risks are too great.

Prioritize major structural and safety issues over minor cosmetic ones. For example, a cracked cornice is different from a problem with a load-bearing wall, and the report should clearly highlight these differences.

Booking and the NSW cooling-off period

In NSW, after you exchange contracts on a private sale, you have 5 business days to change your mind. If you withdraw, you will lose 0.25% of the purchase price. Make sure to schedule your inspection early enough to receive the report and decide within this period.

If you buy at auction, there is no cooling-off period, so the inspection must happen before the auction. Notify the inspector in advance to ensure you have the report before you place your bid.
