The unhappy sequel to a pre-purchase inspection is a defect that was there, or seems to have been there, and did not make the report. Roofs that leak in the first winter. Termite galleries behind a skirt the inspector never moved. A subfloor the report described without anyone having crawled it. These stories travel because they are expensive, and because the inspection felt like insurance until it was not.
Australian law does expect inspectors to take reasonable care. It does not expect them to see through plasterboard. The distance between those two sentences is where most disputes actually live. This is not a guide to suing anyone. It is a guide to reading the obligation that was already in the job, and to keeping the papers that make that obligation intelligible later.
None of what follows is legal advice. Time limits, forums and the meaning of a particular clause depend on the state, the contract, and facts that a journalist cannot see. If the money is serious, speak to a lawyer who does this work. If it is not, start with the inspector anyway. Most missed-defect arguments begin as a conversation and should be allowed to stay one until they cannot.
What “reasonable care” means for a visual inspector
Reasonable care, in this setting, is care that a competent inspector would take in the same circumstances, doing the job described in AS 4349.1 and in the client agreement. It is not perfection. It is not a hunt for every defect a later tradesperson will find with a hammer and a day to spare. It is a systematic look at the accessible building, an honest account of what could not be seen, and enough professional judgement to recognise a major defect or a safety hazard when it is in view.
The standard is doing real work here. If the inspector said they followed it, they said they would inspect the readily accessible areas, including roof space and subfloor where access was reasonable. They said they would report major defects and safety hazards. They said they would record limitations. A buyer who reads the report against those promises already has a method. A buyer who only remembers the summary paragraph does not.
Circumstances matter. An occupied house on a wet Tuesday is not a vacant house in March. A two-storey roof in high wind is not a skillion the inspector can stand on. Reasonable care includes the decision not to die for a photograph. It also includes the sentence that must follow that decision. “Roof exterior not inspected due to weather” is care. Silence is not.
Competence is part of care. An inspector who is out of their depth on a 1890s terrace, or on a 2019 apartment with a combustible cladding question, is not saved by a general licence. Choosing a building inspector is partly a choice about who is allowed to be unsure. The ones who refer out are often the ones who later have less to explain.
The patterns that keep turning up
Complaints against inspectors are not randomly distributed. They cluster around the parts of the house that are annoying to inspect and expensive to repair.
Roofs that were not accessed sit at the top of the list. The report says the roof is in fair condition. The photograph is of the eaves from the ground. Six weeks later a roof plumber finds rusted valley irons and displaced tiles. Sometimes the inspector could not walk the roof and said so. Sometimes they could not and did not. The first is a limitation. The second is a problem.
Subfloors that were skipped are the rural and Queensland version of the same story. Reasonable access has a clearance figure. Below that figure, the inspector is not required to become a speleologist. Above it, “no access” needs a reason. A locked hatch is a reason. A dislike of spiders is not, at least not one the standard recognises. Termite damage and wet-rot in bearers are found in the dark on purpose. If nobody went there, the report should not sound as if somebody did.
“Subject to further investigation” is a legitimate phrase and a bad habit. It is legitimate when the visual evidence is incomplete: a stain that might be old, a crack that might be moving, a moisture reading that needs a tiler. It is a habit when it is attached to every heading so that nothing in the report is ever, quite, a finding. A document full of subjects-to is not a careful document. It is a document that would like not to be quoted.
Photographs that contradict the text are their own genre. The picture shows a splitting rafter; the sentence says the roof frame is typical of its age. The picture shows ponding on a balcony; the sentence recommends monitoring. Tribunals can see pictures. Insurers can see pictures. Anyone reading the report should look at the pictures first, then ask whether the words are willing to keep up.
There are other patterns: wet areas described from the doorway; roof spaces photographed from the manhole; “no pest evidence” offered by a person who was not doing a pest inspection; safety hazards — broken balustrades, live wires in a shed, unguarded pools — mentioned as asides. Each of these can be explained. Each of them, unexplained, looks like a person who was already in the car.
Limitation clauses, and what they can honestly do
The pre-engagement agreement is where the inspector tries to define the job before anyone is upset. Many of the clauses are simply the standard restated: visual only, readily accessible areas, no destructive testing, no warranty, no pest certificate unless commissioned. Those clauses are not an ambush. They are what the report is not, written down at the moment you could still walk away.
Other clauses try to do more. Caps on liability equal to the fee. Requirements that claims be made within a short period. Statements that the report is for the named client only. Obligations to give the inspector a chance to revisit before any repair. Some of this is ordinary risk management. Some of it is an attempt to make careless work consequence-free. Australian consumer law and the general law of negligence sit in the background of those attempts, and they do not always sit quietly.
The point for a buyer is not to become an amateur draftsman. It is to read the agreement as part of the inspection. If the firm excludes all roof work as a matter of policy, you know that before you pay. If the report is said to be for you alone, you know what that means if you later want to show it to a lender, or if you are relying on a vendor’s report. If there is a clause about prompt notice, you know that waiting until the renovation is finished will not help anyone, including you.
A limitation clause is not a moral judgement on the inspector. The absence of one is not a character reference. The work is still the work.
A complaint sequence that does not start in a courtroom
If you believe something was missed, write to the inspector first. Attach the report. Describe the defect as it is now, when you found it, and why you think it was visible on the day. Attach your own photographs. Ask them to come back, or to explain. This is not naivety. It is how professional indemnity actually works. Many insurers want the inspector to have a chance to attend. Many inspectors, faced with a clear case, would rather fix a relationship than fund a lawyer.
If that goes nowhere, the insurer is the next ordinary step, because that is whose name is on the inspector’s policy. You will be asked for the same papers. Keep them in one place. Do not repair the defect into invisibility if you can avoid it, and if you cannot avoid it, photograph everything before the plasterers arrive. The aim is a record, not a shrine.
Industry bodies and state regulators sit alongside that path. Fair Trading, the QBCC, Consumer Affairs, and the various licensing boards do not all do the same thing, and they do not all award damages. They can be the right place for a licence question. They are not always the right place for a money question. Read the jurisdiction you are actually in.
Tribunals and courts are last because they are slow, uneven, and expensive relative to many domestic defects. They are also public. If you go there, go with advice, and go with the documents, not with a feeling that you were let down. Feelings are real. They are not exhibits.
Keep the report, the agreement, the photographs, and the emails. The dispute, if there is one, will be about those objects. It will not be about what you remember saying in the hallway.
Time, and the habit of keeping paper
Time limits vary. Some are limitation periods in the general law. Some are contractual. Some are warranty periods that have nothing to do with the inspector and everything to do with the builder. Online summaries collapse these into a single number, usually wrong. If the defect is serious, do not wait to become an expert in the number. Get advice. If it is not serious, you still should not wait for the house to be renovated into a different house.
Keep the PDF. Keep the invoice. Keep the brief you sent, if you sent one. Keep the agent’s emails about access. If you attended, keep your own notes, dated. If a later tradesperson says “anyone could have seen this”, ask them to put that in a sentence you can store. You may never use any of it. The people who need it are always the people who tidied it away.
Subsequent owners sometimes ask whether they can rely on a report written for someone else. The short journalistic answer is: do not assume so. The legal answer is longer and depends on the facts, the disclaimer, and the state. If you are buying on the strength of a vendor’s inspection, commission your own or take advice about what relying on theirs means. Cheap reports have a way of becoming expensive theories.
Proportion, which is not the same as giving up
Not every missed item is a failure of care. A leaking pipe inside a wall, with no stain and no odour, is why the standard talks about latent defects. A roof that was sound in September and not in February may have been the weather, or may have been a valley the inspector never climbed to. Those two stories look the same from the living room. They do not look the same from the file.
The industry also has a habit of over-correcting. After a claim, some firms write reports that find everything and conclude nothing. That is not care either. It is noise, and it helps nobody except the person who did not want to be quoted. The standards and reports problem is the same one as always: a visual method, a large house, and a buyer who needed a clearer sentence than anyone was willing to write.
If you are still in the buying process, the practical defence is boring. Hire someone who will go into the roof. Read the limitations before the defect list. Ask about the thing you already suspect. Do not instruct anyone to make the house pass. If you are already on the other side of settlement, the practical defence is also boring. Write once, clearly, and keep the paper. Outrage is optional. The file is not.
