Question 2

Walter Moore, a prominent appraiser from Armstrong, British Columbia, is at Lee Morgan’s house for dinner one evening. After dinner, they retire to the living room to watch television, and Walter notices that there is a clear view of the toilet when the bathroom door is open. This is an example of which of the following?

1. A design defect
2. A visible defect
3. A defect of omission
4. An invisible defect

Answer 2

Correct Answer: 1

Option (1) is correct because the defect mentioned in this question is a design defect, because the floor plan of the house has the main bathroom next to the living room, so that the toilet can be seen from the living room when the bathroom door is open. Option (2) is incorrect because a visible defect is typically caused by improper installation, installation of low quality products, improper use and treatment, or a lack of adequate maintenance, which is not the case here. Option (3) is incorrect because a defect of omission is a type of invisible defect due to a lack of moisture barrier, a lack of insulation, a lack of sufficient electrical circuits, a lack of proper roof ventilation, or inadequate attention to air sealing, which is not the case here. Option (4) is incorrect because an invisible defect is one that is hidden behind wall and floor surfaces in a home, which is not the case here.
