Choosing a Building Inspector
Choosing a building inspector is one of those decisions that feels simple until you start looking. A quick search returns dozens of options, all promising thorough inspections and detailed reports. But the quality gap between inspectors can be large, and the consequences of choosing poorly can be costly.
Qualifications: The Baseline
Building inspection in Australia is regulated at the state level. In Western Australia, building inspectors must hold a Builder’s Registration or be supervised by a registered builder. In New South Wales, they need a relevant building licence from NSW Fair Trading.
Ask for the inspector’s licence number and verify it. Any inspector who hesitates to provide their credentials is not worth your time.
Once the minimum regulatory basics are verified, focus on the things that actually change the quality of the inspection:
Defect volume and report depth. Ask how many inspections sit behind the inspector’s judgement and whether their reports are informed by a structured defect history, not just memory.
Local accountability. A territory owner who works the same suburbs every week knows the local construction eras, soil movement, termite pressure, and recurring builder patterns.
Specific inspection qualifications. A builder’s licence qualifies someone to build, not necessarily to inspect to AS 4349.1. Look for inspectors who have completed specific building inspection training or who hold qualifications that explicitly cover the inspection standard.
Experience: What It Actually Means
“20 years experience” means different things depending on what those 20 years involved. An inspector who spent 15 years in new residential construction and 5 years inspecting has a deep understanding of how houses are built, and what goes wrong.
An inspector who worked in commercial construction for 20 years and recently started doing residential inspections may not recognise the specific defect patterns common in Perth double-brick or Sydney fibro-and-tile housing.
Ask about the inspector’s background:
- How many residential inspections do they perform per week?
- What types of properties do they inspect most frequently?
- Are they familiar with the specific construction type and era of the property you’re purchasing?
An inspector who regularly inspects 1970s brick-and-tile homes in Perth’s northern suburbs will spot different issues than one who primarily inspects new builds in growth corridors. Both are valid, but matching the inspector’s experience to your property type is important.
Report Quality: The Deliverable That Matters
The inspection is invisible to you, you’re paying for the report. Before you book, ask for a sample report. A quality report should include:
Clear structure. Organised by area (exterior, interior, roof, sub-floor, wet areas, drainage, outbuildings) with each finding individually described, photographed, located, and severity-classified.
Photographs for every finding. Not just a handful of hero shots, but individual photographs showing each defect with enough context to identify its location. A report that describes a crack but doesn’t show it is incomplete.
Severity classifications. Every finding should be classified, minor, moderate, significant, or major. This helps you understand what matters and what’s routine maintenance.
Specific language. “Some cracking was observed” is not useful. “Stepped diagonal cracking in the east elevation brickwork, measuring approximately 3mm at its widest point with 1mm vertical displacement, extending from the window lintel to the eave line” tells you what’s happening and how serious it is.
Recommendations. Each significant finding should include a recommended course of action, repair, monitor, or further investigation by a specialist.
Prompt Reports: Why Timing Matters
In a competitive property market, you’re often working within a cooling-off period (5 business days in NSW) or a finance clause deadline. A report that takes 3-5 days to arrive is a report that arrives too late to be useful.
Prompt reporting should be standard, not a premium add-on. At SURE Building Inspections, same-day delivery is subject to access and availability because timely information helps you make decisions.
Red Flags to Watch For
Avoid any inspector who:
Won’t provide their licence number. Operating without the correct licence is illegal and voids any professional indemnity insurance.
Offers unrealistically low prices. A thorough inspection of a standard residential property takes 2-3 hours on site plus reporting time. An inspector charging well below market rate is cutting corners somewhere, on time, on reporting, or on both.
Doesn’t carry professional indemnity insurance. If they make a mistake, you have no recourse.
Refuses to provide a sample report. If they’re not proud of their work product, that’s a signal.
Guarantees a “clean” result. No inspector can promise a favourable outcome before they’ve seen the property. Anyone who implies they’ll go easy to help the sale proceed is not acting in your interest.
Is also the selling agent’s recommended inspector. Conflict of interest. The agent has a financial incentive for the sale to proceed, they should not be selecting the inspector whose report will determine whether it does.
Combining Building and Pest
If you need both a building and a pest inspection (and in most cases you do), an inspector qualified in both disciplines saves time, money, and coordination. A single site visit, a single report delivery, and, importantly, a single professional who can correlate building and pest findings rather than viewing them in isolation.
The Bottom Line
The right inspector gives you confidence in one of the largest financial decisions you’ll make. They find what matters, explain it clearly, deliver it promptly, and are available to answer your questions after the report.
The wrong inspector gives you a false sense of security, or an unnecessarily alarming list of findings without the context to interpret them.
