Pre-Purchase Inspections for Residential Property: What an AS 4349 Report Covers

Pre-purchase property inspections in Australia are not statutory. They sit behind a contract condition. Reports follow AS 4349.0 generally and AS 4349.1 for residential.

What it is

A pre-purchase property inspection is a visual report on the condition of a residential property prepared before settlement. It is not statutory in any Australian jurisdiction. It usually sits behind a special condition in the contract of sale that lets the purchaser walk away or renegotiate if the report identifies major defects. The two standards that govern the work are AS 4349.0:2007 Inspection of buildings - General requirements and AS 4349.1:2007 Inspection of buildings - Pre-purchase inspections - Residential buildings.

The inspector is typically a registered builder, building consultant or qualified inspector with professional indemnity insurance. In some states they need a builder's licence or equivalent to scope structural matters. In Victoria, for example, only a registered building practitioner under the Building Act 1993 should be reporting on building work. Building inspectors do not value the property. They do not certify compliance with the National Construction Code. They report what a competent inspector can see during a visual examination of the readily accessible parts of the property.

What the report covers

AS 4349.0 sets the scope. The inspector reports on the condition of the property at the time of inspection, identifies major defects, minor defects and any safety hazards, and lists the items that could not be inspected because they were not accessible. The Standard explicitly excludes the inspection of timber pests, pools and spa equipment, smoke alarms, electrical wiring beyond the visual condition, plumbing pressure testing, gas fittings, air conditioning systems and any concealed parts of the building.

AS 4349.1 narrows this to residential pre-purchase use. The inspector walks the site, the roof exterior, the roof space, the subfloor where accessible, the interior and the immediate site. They look for structural cracking, sagging or distorted framing, water staining, signs of movement, deteriorated finishes, drainage issues at the perimeter and any obvious safety risks like missing balustrades, low-height pool fencing or trip hazards.

Timber pest inspections

A timber pest inspection runs under AS 4349.3 (Timber pest inspection) or sometimes AS 3660.2 (Termite management). It looks for evidence of termite activity, past damage, fungal decay and borers. It is a separate engagement to the AS 4349.0 inspection and is usually quoted separately. Best practice is to commission both inspections together because the access requirements overlap and the cost is lower as a package.

What the report does not cover

Pre-purchase reports are limited by what is reachable on the day. A locked subfloor, a tile roof the inspector cannot safely walk, an attic with no manhole, stored possessions covering floors and walls and bad weather all reduce coverage. The report must list these limitations. Anything behind plasterboard, render, tiles or wall cavities is concealed and out of scope unless the inspector has authority to do invasive testing. The report does not certify the building as defect-free. It is a snapshot of the visible condition on a single day.

How it fits into the contract

In NSW, VIC, QLD, WA, SA, TAS, ACT and NT, the standard residential contract of sale allows the purchaser to make the contract conditional on a satisfactory pre-purchase inspection. The condition usually sets a number of business days to obtain the report and a definition of major defect or major fault. If the report identifies issues that meet the contract definition, the purchaser can rescind or renegotiate within the condition period. Outside that window the purchaser holds the building as they find it.

In Victoria the Sale of Land Act 1962 and the vendor statement (section 32 statement) do not replace a pre-purchase inspection. The section 32 covers title and known building approvals. It does not warrant condition.

Choosing an inspector

The inspector should be independent of the vendor and the agent, hold professional indemnity insurance of at least $1 million, work to AS 4349.0 and AS 4349.1, provide a written quote that confirms the scope and provide a sample report on request. The cheapest inspector is rarely the best value. A two-page tick-and-flick report on a $1.2 million home is false economy. A detailed photographic report runs 30 to 60 pages and gives the purchaser something the conveyancer can act on.

After the report

If the report flags major defects, the purchaser has three live options. Walk under the condition. Renegotiate the price by the cost of rectification. Proceed and budget for the work. State fair trading bodies (NSW Fair Trading, Consumer Affairs Victoria, QBCC and others) publish guidance on the use of pre-purchase reports and what counts as a major defect in their jurisdiction.
