Reporting defects practice questions
10 free defect reporting questions in the style of the National Home Inspector Exam, each with the answer and the reason. The official outline calls this task "Describe defective components" and gives it 6% of the exam, about 11 of the 175 scored questions.

Question 1 of 10
How long pyrolysis takes to lower the ignition temperature of wood depends on the:
The answer is DThe manual ties the length of the pyrolysis process to the temperature of the exposure and how frequently it happens, and says the process can take many years. Wood species, fuel type, and finish are not the factors it names. This slow process is why a clearance deficiency can go years or decades before it causes ignition.
Question 2 of 10
A condition could cause only a minor scrape that needs no treatment by a doctor, although the scrape is likely during normal use. Under the manual's criteria, the condition is:
The answer is CA condition is unsafe only when all three criteria are satisfied: serious injury could occur, the risk is significant, and the injury could happen during normal use. The manual's working definition of a serious injury is one that needs a doctor's care, so a scrape needing none fails the first criterion. Meeting two criteria is not enough.
Question 3 of 10
Compared with a component nearing the end of its service life, the replacement expectation for one that has reached or passed that point is set for:
The answer is AFor a component nearing the end of its life, a typical statement sets expectations for a replacement at an unspecified later date. For one that has reached or passed the end, failure is more likely, so the home inspector should prepare the client for higher maintenance costs and a replacement that could come soon. Neither statement should estimate the years left.
Question 4 of 10
The definition of habitability that the manual quotes is taken from:
The answer is AThe manual quotes its habitability definition from the seventh edition of Black's Law Dictionary. The HUD Residential Rehabilitation Guide is the published list of expected service lives the manual names, not the source of this definition.
Question 5 of 10
The appropriate response to an imminent threat depends on:
The answer is CThe manual ties the response to the level of the threat and to the conditions present during the inspection. A life safety threat such as a significant fuel leak inside calls for everyone to leave, while a leaking water distribution pipe calls for an attempt to shut off the water. Agent preferences do not set the response.
Question 6 of 10
The client's agent phones the listing agent about a gas leak while the home inspector listens. Does this meet the manual's expectation for notification?
The answer is DThe home inspector should notify the property owner or a person acting for the owner, attempt to, or witness another person do it. The listing agent is the preferred representative, so a call the inspector witnesses meets the expectation. The inspector should still document the call and the actions taken.
Question 7 of 10
During an imminent threat, the condition the manual attaches to taking pictures is that
The answer is CPictures are part of the record the manual asks for during an imminent threat, alongside notification attempts and actions taken to limit damage. The condition attached is safety: the home inspector should take them only where doing so is safe.
Question 8 of 10
Some SoPs describe deficient conditions with uncommon terms. What does the manual say about such terms?
The answer is BMost SoPs share similar terms for the general conditions an inspector is expected to find and report; however, some use other terms whose meaning can be unclear. Even the common terms may be defined differently from one jurisdiction to another, depending on how regulators and courts read them.
Question 9 of 10
A water heater is only a few years old, but it was improperly installed and shows deterioration. Can its service life be nearly over?
The answer is AAge usually weighs heavily when judging how much life a component has left, but other factors count too. Damage, deterioration, and improper installation can all shorten how long a component lasts. A component can reach the last part of its life before its warranty runs out and without any leaking, as the manual shows with three-tab fiberglass shingles.
Question 10 of 10
Two condensers of average quality are the same age. One sits near the ocean and the other far inland. Why might the one near the ocean have less service life remaining?
The answer is ADeterioration from salt spray can cut a condenser's expected service life to five years near the ocean, compared with the usual fifteen years for an average quality condenser in many areas. The manual gives salt spray as the cause, not refrigerant loss or hours of operation.
