Under NFPA 13R, what is the garage sprinkler rule?

• A. Sprinklers prohibited in all garages.
• B. Sprinklers allowed if connected to a single dwelling.
• C. Sprinklers allowed if connected to a multi-dwelling building.
• D. Sprinklers required in all garages.

Answer: (B)

NFPA 13R allows sprinkler protection in an attached garage only when the garage is connected to a single dwelling. This recognizes the fire risk path from a garage into the living space of a single-family home, so protection there is permitted to help limit spread. If the garage serves a multi-dwelling building, that allowance doesn’t apply. Sprinklers are not required in all garages, and they’re not allowed in every attached garage or in garages for multi-dwelling buildings, which is why the only correct take is that sprinklers are allowed if the garage is connected to a single dwelling.
