The area of openings in an open parking structure must not be limited if the fire distance is greater than how many feet?

The correct answer is based on the building code provisions that dictate fire safety standards for open parking structures. Specifically, when the fire distance—defined as the distance from the building to the property line or to an adjacent building—is greater than 10 feet, the area of openings in the parking structure is not restricted. This regulation is intended to ensure that the risk of fire spread is minimized while allowing for adequate ventilation and light in the structure.

In scenarios where the fire distance is greater than 10 feet, the potential for fire to affect adjacent properties is deemed to be lower, thus permitting larger openings without compromising safety. These regulations are put in place to balance practical design needs with the necessary precautions to protect public safety from fire hazards.
