What is the minimum height requirement for barriers in a public parking garage?

The minimum height requirement for barriers in a public parking garage is specified to ensure safety and compliance with building codes. The correct height of 2 feet 9 inches is established to provide adequate protection for pedestrians and vehicles in the garage. This height is necessary to effectively prevent vehicles from accidentally driving over the barrier and to delineate safe walking areas clearly.

Barriers that are too low may not provide sufficient visibility or physical obstruction, which can lead to accidents or unauthorized access. A height of 2 feet 9 inches strikes a balance between being tall enough to provide safety without obstructing visibility for drivers. In comparison, heights below this standard, such as 2 feet or 2 feet 6 inches, may not adequately serve these protective functions.
