Parapet walls constructed of unreinforced hollow masonry units shall be not less than how many inches thick?

6 inches
8 inches
10 inches
12 inches

The correct answer is: 8 inches

The correct answer is based on the building codes and standards that govern the construction of parapet walls. Parapet walls made from unreinforced hollow masonry units must be a minimum thickness of 8 inches. This requirement is crucial for ensuring the structural integrity and stability of the wall, especially in areas prone to high winds or seismic activity. A thickness of 8 inches provides sufficient strength to resist lateral forces and minimizes the risk of failure. Building codes take into account factors such as material properties, environmental conditions, and safety standards when determining minimum thickness requirements. By adhering to this standard, inspectors can ensure that parapet walls will perform adequately over time and protect the overall structure from potential damage.
