Which sprinkler requirement applies to balconies and closets?

• A. Sprinklers not required on balconies or closets.
• B. Sprinklers required on balconies or closets.
• C. Sprinklers required on balconies but not closets.
• D. Sprinklers required on closets but not balconies.

Answer: (A)

In NFPA 13R for low-rise residential buildings, certain spaces are exempt from sprinkler installation to simplify the system while still protecting occupants. Balconies are typically open to the outdoors, and closets generally have limited fuel load and are small relative to other living spaces. The protection provided by sprinklers in the surrounding living areas is considered sufficient to manage fires without needing heads installed specifically in these spaces. That’s why, in this context, sprinklers are not required on balconies or within closets.
