A building inspection report is most useful when it leads to a clear set of questions and actions. Reading only the summary can miss inaccessible areas, recommended investigations or qualifications elsewhere in the document. Start by understanding what the inspector was engaged to assess and what they could actually see.
Our building and pest inspector referral service connects buyers with independent professionals. This guide is about using their report, not replacing their judgement. The property inspection checklist covers your own walkthrough before a professional inspection.
Read the scope before the defect list
Check the property address, inspection date, weather, areas inspected and exclusions. The NSW Government explains that a pre-purchase building report generally identifies major problems visible at the time; it is not a compliance certificate or insurance against future defects. Concealed parts and matters outside the consultant's expertise may not be covered.
Look for roof-space, subfloor or other access restrictions. An area recorded as inaccessible has not been cleared of defects. Ask what practical steps could improve access, whether reinspection is possible and whether uncertainty affects your decision.
Turn findings into an action register
- Record the defect, location and report reference rather than paraphrasing it as 'the house is fine'.
- Ask whether the observation concerns safety, structural risk, moisture, maintenance or another issue.
- Separate a confirmed observation from a possible cause or recommendation to investigate.
- Identify the appropriate specialist and whether their work requires separate permission or access.
- Record the follow-up deadline, especially if a contract condition is approaching.
- Keep the inspector's clarification and any later report alongside the original.
Do not infer repair costs from severity alone
A description such as 'major defect' does not automatically provide a repair quote, and a short entry can still require substantial investigation. Ask how the report defines its categories. Standard reporting scope may exclude cost estimates, minor defects or testing of services; confirm what was commissioned.
A hypothetical report noting moisture near a bathroom could have several possible causes. A photograph does not establish whether the problem is a surface leak or concealed waterproofing failure. A suitable tradesperson or specialist may need to investigate before quoting, and the cost could change once the cause is known.
Coordinate the technical and legal questions
Give material findings to your conveyancer as well as discussing them with the inspector. The inspector explains condition; the conveyancer explains what the contract allows and how notices or negotiations must be handled. A concerning report does not automatically create a right to cancel or reduce the price.
Ask whether building and pest assessments were both included. A building inspection is not automatically a timber pest inspection, electrical inspection or assessment of every pool, appliance and service. Commission extra work where it is relevant rather than assuming a general report covers it.
Decide with the remaining uncertainty visible
Compare the follow-up evidence, known work and uninspected areas with your budget and tolerance for risk. If further investigation cannot be completed in time, raise that fact with your advisers. Do not convert a recommendation for further assessment into a finding that nothing is wrong.
A report wording question
Does 'no major defects observed' mean the property has no defects?
No. It describes observations within the inspection scope and conditions at that time. Read the limitations and minor findings, ask about inaccessible areas and confirm whether other reports are needed.
