Why do Pre-Purchase Building Inspectors have Professional Indemnity claims

17, Apr 2025

Building inspectors conducting pre-purchase inspections to AS 4349.1–2007 are exposed to a high number of professional indemnity (PI) claims in Australia due to several recurring risk factors:


1. Missed Defects

  • The most common cause of PI claims is failure to identify or report major structural issues (e.g. termite damage, subsidence, roof faults).
  • Buyers rely heavily on these reports and may sue if defects are discovered after settlement.

2. Inadequate or Vague Reporting

  • Use of ambiguous language (“minor cracking observed”) or failure to recommend further inspection can lead to claims.
  • If inspectors don’t clearly highlight risks or limitations, clients may claim negligence.

3. Inaccessible Areas Not Properly Noted

  • If parts of the property were not inspected (e.g. roof void, subfloor) and this wasn’t properly documented, the inspector may be liable for omissions.

4. Lack of Supporting Evidence

  • Failure to include clear photographs and detailed comments in the report makes it harder to defend a claim later.

5. Misinterpretation of AS 4349.1 Scope

  • Some inspectors overstep the standard (e.g. making structural or pest assessments) without proper qualifications or try to go beyond a visual-only inspection, which can backfire if they miss something

6. Clients Expecting a Warranty

  • Buyers often wrongly assume a building report is a guarantee, not an opinion based on a moment-in-time inspection.
  • This misalignment of expectations frequently leads to disputes and litigation.

7. Claims Arising Years Later

  • Claims may emerge years after the inspection, especially when structural problems or pest damage become evident over time.

Why PI Insurance is Crucial

  • Professional Indemnity insurance covers:
  • Legal defence costs
  • Damages awarded
  • Claims alleging negligence, misstatements, or omissions
