Chapter 39 Quiz: Home Inspections
Multiple Choice
1. A home inspector observes a crack in a basement wall and writes "recommend evaluation by structural engineer." This means:
A) The inspector believes the crack is definitely structural and dangerous B) The inspector has found something beyond the reliable limits of their visual assessment and believes the risk of not knowing more is significant C) The crack is cosmetic and the inspector is being overly cautious D) The inspector is required by law to recommend engineers for all cracks
Answer: B. Inspectors are generalists. When they recommend a specialist, it means they've identified the edge of what they can assess reliably. It is not a diagnosis of severity — it's an honest acknowledgment of the limits of a visual inspection.
2. Which of the following is NOT within the standard scope of a home inspection?
A) Testing the furnace by running a heat cycle B) Operating every accessible electrical outlet C) Camera inspection of the main sewer lateral D) Checking for evidence of past moisture in the basement
Answer: C. Sewer scopes are a specialty inspection. Standard home inspections cover visible, accessible components. The interior of drain pipes requires camera equipment and is explicitly excluded from a standard inspection's scope.
3. The Chen-Williams household paid $8,400 for a sewer lateral repair shortly after closing on their 1963 house. What specialty inspection could have identified this problem before purchase?
A) Radon air test B) Level II chimney inspection C) Thermal imaging D) Sewer scope inspection
Answer: D. A sewer scope — a camera inserted into the drain cleanout — would have shown the root intrusion and deteriorated clay pipe joints in the lateral before purchase. Cost: $200–$400. The repair it would have identified: $8,400.
4. An inspection report item tagged "monitor — deteriorating chimney crown mortar" should be:
A) Ignored, since it's not tagged as a repair item B) Repaired only if water enters the chimney within 12 months C) Transferred to a maintenance log with a specific follow-up date D) Negotiated as a seller credit before closing
Answer: C. "Monitor" items require a system. Without a specific calendar follow-up date, they remain unaddressed until they escalate into repair or safety items. Every monitor item should get a date in a maintenance log.
5. A home inspector is primarily responsible for:
A) Certifying that the house is code-compliant B) Identifying structural defects that require engineering analysis C) Providing a visual assessment of accessible systems and components at a specific point in time D) Guaranteeing the condition of all systems for 12 months after the inspection
Answer: C. This is the core definition of a home inspection's scope. Inspectors are generalists performing visual assessments — not code compliance certifiers, engineers, or guarantors of future performance.
6. When negotiating repairs after an inspection, the most effective approach is generally to:
A) Submit a request for every item on the inspection report B) Request that the seller fix all items before closing using contractors of their choice C) Focus on the 20% of items that represent 80% of the financial risk D) Accept the house as-is to strengthen your offer
Answer: C. Submitting every item, including cosmetic issues, dilutes your negotiating leverage and frequently causes sellers to push back on everything, including legitimate concerns. Focus on safety, structural, and major mechanical items.
7. Radon is particularly dangerous because:
A) It corrodes plumbing and electrical systems B) It is odorless and invisible, and long-term exposure significantly increases lung cancer risk C) It only affects homes in the western United States D) It requires structural remediation costing $20,000 or more
Answer: B. Radon is a naturally occurring radioactive gas — odorless, colorless, undetectable without testing. It is the second leading cause of lung cancer in the United States after smoking. Remediation when needed typically costs $800–$2,500, not $20,000.
8. A seller who has a pre-listing inspection performed should be aware that:
A) The cost is typically covered by the buyer's agent B) Identified defects will likely trigger disclosure obligations in most states C) Buyers cannot conduct their own inspection after a pre-listing inspection has been done D) Pre-listing inspections are only valid for 30 days
Answer: B. In most states, once a seller knows about a defect — including through their own pre-listing inspection — they are required to disclose it to buyers. This is the primary downside of pre-listing inspections, though most real estate professionals consider the advantages of no surprises to outweigh this risk.
9. Inspectors are typically unable to evaluate air conditioning systems when:
A) The house is unoccupied B) Outdoor temperatures are below approximately 65°F C) The system is more than 10 years old D) The system uses a heat pump rather than a standard split system
Answer: B. Running the AC compressor when outdoor temperatures are too low risks damage to the compressor. Inspectors following professional standards do not operate AC systems in cold weather — which means a spring inspection in a cool climate may not test the AC at all.
10. Which of the following best describes why a home inspector is generally not liable for defects hidden inside walls?
A) Home inspectors carry no professional liability insurance B) The inspection contract typically waives all liability C) Inspectors perform visual-only assessments and cannot detect what is not accessible or visible D) In-wall defects are always the responsibility of the previous owner
Answer: C. The scope of a home inspection is explicitly limited to what is visible and accessible. Inspectors carry E&O insurance for things they should have noticed but didn't — not for things that were genuinely hidden. Errors and omissions policies apply to negligent missed observations of accessible conditions, not to conditions inside closed walls.
Short Answer
11. Explain the difference between a "repair recommended" item and a "monitor" item in a home inspection report. Why does the distinction matter for a home buyer?
Sample answer: A "repair recommended" item identifies an existing defect that requires correction — there is a problem present and it should be fixed. A "monitor" item identifies a condition that is not currently defective but may develop into one, or where changes over time are worth tracking. The distinction matters because repair items require immediate action and are typically negotiable in a purchase transaction, while monitor items require ongoing attention. The danger with monitor items is that buyers tend to ignore them after closing — but without a system to follow up, a monitored condition can deteriorate into a much more expensive repair over time.
12. The Rodriguez family's original inspection report from 1998 had 43 items. Twenty-six years later, Isabel categorizes roughly 12 of those items as maintenance recommendations she didn't follow — items that generated approximately $23,000 in additional repair costs. What does this pattern tell us about how homeowners should approach the "maintenance" and "monitor" sections of an inspection report?
Sample answer: Maintenance and monitor items represent the highest potential cost for homeowners who don't act on them. They don't feel urgent at the time of purchase — they lack the psychological weight of safety items — but deferred maintenance compounds. Water infiltration that could be stopped with $200 in caulk becomes $5,000 in rotted framing. HVAC filter neglect becomes coil cleaning or early equipment replacement. The Isabel Rodriguez case study illustrates that the "boring" maintenance items in an inspection report deserve as much attention as the dramatic safety items — maybe more, because they're the ones that get skipped.
13. A first-time home buyer asks whether they need specialty inspections when purchasing a 1958 single-family house with a fireplace, a large oak tree in the back yard, and a crawlspace. What would you recommend and why?
Sample answer: At minimum, three specialty inspections are strongly warranted: (1) Sewer scope — a 1958 house almost certainly has clay or cast iron drain lines, both of which are prone to root intrusion, deterioration, and joint separation. The large oak tree significantly elevates root intrusion risk. Cost: $200–$400; potential avoided repair: $5,000–$15,000. (2) Radon test — standard for all home purchases; inexpensive and the downside risk of undetected radon exposure is severe. Cost: $100–$200. (3) Level II chimney inspection — a fireplace in a 68-year-old house with an unknown maintenance history needs a camera inspection of the flue liner. Cracked liners are a fire and CO hazard. Cost: $200–$400. Lead paint testing is also advisable given the age, particularly for buyers with young children.
