10 Free Home Inspector (NHIE) Practice Questions
Q1. An inspector observes wood shingles that are sawn smooth on both sides. What is the most appropriate report recommendation?Show answer
✓ Correct Answer: Wood shingles, not shakes
InterNACHI and ASHI standards recognize this condition as part of a visual home inspection. Wood shingles are sawn, while shakes are split and have a rougher profile. The inspector should identify the material and report visible deterioration or installation defects.
Q2. An inspector observes soil sloping toward the foundation wall. What is the most appropriate report recommendation?Show answer
✓ Correct Answer: Negative grading that increases water intrusion risk
IRC site drainage requirements recognize this condition as part of a visual home inspection. Grade should slope away from the building, commonly 6 inches within the first 10 feet where feasible. Negative grading should be reported because it directs water toward the foundation.
Q3. An inspector observes stair-step cracks following mortar joints in a CMU foundation. What is the most appropriate report recommendation?Show answer
✓ Correct Answer: Possible differential settlement requiring further evaluation
Inspection standards for structural systems recognize this condition as part of a visual home inspection. Stair-step cracks in block walls can indicate movement or differential settlement. The inspector should report location, width, displacement, and recommend evaluation when significant.
Q4. What is the best next recommendation after finding a forced-air furnace filter packed with debris?Show answer
✓ Correct Answer: Restricted airflow that can reduce performance and damage equipment
ASHI and InterNACHI HVAC inspection standards recognize this condition as part of a visual home inspection. A clogged filter restricts airflow and can contribute to overheating, poor comfort, and coil icing. The inspector should report the condition and recommend replacement.
Q5. An inspector observes a water heater missing its temperature-pressure relief valve. What is the most appropriate report recommendation?Show answer
✓ Correct Answer: Serious safety hazard requiring correction
IRC P2804 and inspection standards recognize this condition as part of a visual home inspection. A TPR valve protects against dangerous temperature or pressure buildup. Missing relief protection is a safety-critical defect.
Q6. An inspector observes stored boxes blocking access to the main electrical panel. What is the most appropriate report recommendation?Show answer
✓ Correct Answer: Insufficient working clearance at electrical equipment
NEC 110.26 and inspection standards recognize this condition as part of a visual home inspection. Electrical panels need clear working space, commonly 36 inches deep, 30 inches wide, and 78 inches high. Blocked access should be reported as a safety concern.
Q7. Which defect classification is most appropriate for a modern home has a 60 amp electrical service with numerous added loads?Show answer
✓ Correct Answer: Potentially undersized service requiring electrician evaluation
NEC service load principles and inspection standards recognize this condition as part of a visual home inspection. Service adequacy depends on calculated load, not age alone. A small service with added loads should be evaluated by a qualified electrician.
Q8. During a home inspection, soffit vents blocked by insulation at the eaves. What is the primary concern?Show answer
✓ Correct Answer: Restricted intake ventilation
IRC attic ventilation principles recognize this condition as part of a visual home inspection. Attic ventilation should include intake and exhaust paths. Blocked soffits reduce airflow and can contribute to heat and moisture problems.
Q9. Which standard-based response fits an exterior door has daylight visible at the threshold during a visual inspection?Show answer
✓ Correct Answer: Weatherstripping or threshold defect allowing air and water entry
Inspection standards for doors and exterior openings recognize this condition as part of a visual home inspection. Exterior doors should reasonably resist weather entry. Gaps at thresholds can allow water, pests, and air leakage.
Q10. Which standard-based response fits the report requirement to identify systems and describe deficiencies during a visual inspection?Show answer
✓ Correct Answer: Required by common home inspection standards
ASHI and InterNACHI standards of practice recognize this condition as part of a visual home inspection. Reports identify inspected systems and describe observed deficiencies. Clear descriptions help clients understand condition and recommended action.
What Does the Home Inspector Exam Cover?
The National Home Inspector Examination (NHIE), administered by the Examination Board of Professional Home Inspectors (EBPHI), tests both the systems and components of a house and the professional practice of inspecting. Systems content spans site and grading (positive vs. negative drainage), roofing (identifying wood shingles vs. shakes, flashing, coverings), structure and foundations (recognizing stair-step cracks and differential settlement), exterior and interior, plumbing (water heaters and TPR valves), electrical (service size, panel working clearances per NEC 110.26), HVAC (airflow, filters, ventilation), and insulation and attic ventilation (intake and exhaust balance). Practice content covers standards of practice, report writing, and ethics — identifying inspected systems and describing observed deficiencies. Roughly 30 states require passing the NHIE for licensure.
How Hard Is the NHIE?
The NHIE is a broad, four-hour exam that spans every major house system plus standards of practice and business, so its main challenge is breadth rather than trick questions. It is scale-scored from 200 to 800, and a score above 500 passes. The most commonly missed items ask you to classify an observed condition and choose the correct report recommendation — for example, whether soil grading is a defect, whether a missing TPR valve is a safety hazard, or whether a blocked panel violates working-clearance requirements. Applying inspection standards to a described condition is the skill that is tested.
How to Study for the NHIE
- 1.Study by house system — Roofing, exterior and grading, structure and foundation, electrical, plumbing, HVAC, interior, and insulation/ventilation. Learn the common defect for each system and the correct report recommendation, because that is how NHIE items are framed.
- 2.Learn the safety-critical items cold — A missing water-heater temperature-pressure relief (TPR) valve, blocked electrical-panel working clearance (NEC 110.26 requires roughly 36 inches deep, 30 wide, 78 high), and negative grading toward the foundation are classic must-report hazards.
- 3.Know the standards of practice — ASHI and InterNACHI standards define what a visual inspection must identify and how deficiencies are described. Report-writing and ethics questions reward knowing what is required versus what is cosmetic or optional.
- 4.Memorize key numbers and rules of thumb — Grade should slope away from the building (commonly 6 inches within the first 10 feet), attic ventilation needs balanced intake and exhaust, and service adequacy depends on calculated load, not age. Precise figures show up on the exam.
- 5.Practice condition-to-recommendation questions under time — The NHIE gives you 4 hours for about 200 questions. Drill scenario items where you classify an observed condition and pick the standard-based response until you consistently clear a passing margin.
