Building and pest inspection cost in Sydney

A combined building and pest inspection for a standard house in Sydney typically costs around $550 to $1,100, and more for large, heritage or inner-city homes, according to cost guides in late 2026. A building inspection for an apartment usually costs less, as the inspector mostly looks at the inside of the unit. Get two or three quotes, and check what the report will cover before you book: the cheapest inspection isn't the best value if it leaves out the areas you're most worried about.

Typical prices in Sydney

These are typical ranges quoted by independent cost guides in 2026. Prices vary with the inspector, the property and how quickly you need the report.

• Pest (timber pest) inspection only: around $250 to $500
• Building inspection only, apartment or small home: around $350 to $700
• Combined building and pest, standard house: around $550 to $1,100
• Combined building and pest, large, heritage or inner-city home: around $850 to $1,700
• Extras such as thermal imaging or asbestos testing: often a few hundred dollars each

What affects the price

• The size of the property. More rooms, levels and roof area take longer
• Age and construction. Older homes, heritage homes and those with subfloors take more time
• Access. Steep blocks, high roofs and tight subfloors can add cost
• Speed. Same-day or next-day reports often cost more
• Extras. Thermal imaging, moisture testing, drone roof photos and asbestos sampling are often charged separately

What a building and pest inspection covers

A pre-purchase inspection in NSW is usually a visual check of the areas the inspector can safely reach: the inside and outside of the building, the roof space, the subfloor and the site. It looks for major defects, safety hazards and signs of termites or timber damage.

It usually doesn't cover:

• Areas the inspector couldn't get to: a blocked roof space, a locked room, a subfloor with no access
• Plumbing and electrical systems, beyond what can be seen
• Whether the work has council approval
• Pools, beyond what's visible
• Common property in an apartment building

Our guide to what a building and pest report doesn't tell you explains how to cover those gaps.

Apartments are different

For an apartment, a building inspection usually covers the inside of the unit and what the inspector can see of the common property. The roof, the facade, the car park and the building's waterproofing are owned by the owners corporation, and their condition is in the strata records, not the inspection. That's why an apartment needs a strata report as well as an inspection.

How to get value from the inspection

• Book early, so the report is back before the cooling-off period ends or before the auction
• Attend the inspection if you can, and ask questions on site
• Ask about access. If the roof space or subfloor can't be reached, ask the agent to arrange access, or ask the inspector to come back
• Read the "not inspected" section as closely as the defects. An area not inspected is not an all-clear
• Check the inspector's insurance and licence, and that the report follows the Australian Standard for pre-purchase inspections

When to spend more

Some properties justify a more detailed inspection or a specialist:

• Older homes and heritage homes
• Homes with signs of cracking, movement or water damage
• Recent renovations or extensions
• Homes near bushland, which are more likely to have termites
• Sloping blocks with retaining walls

A structural engineer, plumber or electrician may be worth the extra cost if the inspector recommends one.

Who pays

The buyer usually pays for the building and pest inspection. Some selling agents provide a report with the contract. If so, check who it was prepared for, how recent it is, and whether you can rely on it. Many reports are only for the person who ordered them.

Questions

Is a building and pest inspection worth it for a new home?

Yes. New homes can have defects too, and an independent inspection before the builder's warranty runs out can save you from fixing the builder's mistakes yourself.

How long does the inspection take?

Usually one to three hours on site, depending on the size of the property, with the report often ready within a day.

What should I do if the report finds a major defect?

Talk to your solicitor or conveyancer straight away. You may be able to negotiate the price, ask the seller to fix it, or, if you're in the cooling-off period, withdraw from the purchase.
