True or False: An enclosed accessible space under stairs should be protected on the enclosed side with a 1/2-inch gypsum board.

An enclosed accessible space under stairs should indeed be protected on the enclosed side with a 1/2-inch gypsum board. This requirement is part of fire safety regulations, ensuring that any potential fire within that space does not easily spread to the rest of the structure. Gypsum board acts as a barrier, helping to contain fire and providing additional time for occupants to evacuate in case of an emergency.

Moreover, the inclusion of protective materials like gypsum board helps to reduce the risk of combustion and increases the fire resistance of the enclosed area, making it safer for storage and other uses. This measure supports both building codes and best practices for residential safety.
