Which type of construction must have sprinkler protection installed on exterior balconies and decks if there is a roof or deck above?

Sprinkler protection must be installed on exterior balconies and decks if there is a roof or deck above, specifically in Type V construction. This type of construction is typically made of wood, which is more combustible than the materials used in Types I or III. Due to the increased fire risk associated with the use of combustible materials in Type V buildings, additional safety measures such as sprinkler systems are required to enhance fire protection.

Type V construction is usually found in residential buildings, and the inclusion of sprinklers on balconies and decks serves to mitigate the potential for fire spread from one area to another, especially in the event that a fire starts in or near the balcony or deck areas. This enhances overall safety for occupants and property by providing a proactive response to fire hazards.

In contrast, Types I and III have different requirements based on their inherent fire resistance, and Type VII is not a standard classification recognized in the same context. Thus, the need for sprinkler protection on exterior surfaces specifically pertains to the characteristics and safety protocols mandated for Type V construction.
