In a single-dwelling structure, is sprinkler protection required in the attached garage?

• A. Sprinklers are allowed.
• B. Sprinklers are prohibited.
• C. Only in detached garages.
• D. Not specified.

Answer: (A)

In NFPA 13R for low-rise residences, protecting an attached garage is not mandatory, but it is permitted. The standard aims to provide cost-effective life safety for one- and two-family dwellings and does not require sprinkler protection in an attached garage; you may install garage sprinklers if desired, depending on risk assessment or local code amendments. This is why the correct approach is that sprinklers are allowed. The other options imply a prohibition, a restriction to detached garages, or no guidance at all, which don’t reflect the permissive stance of 13R for attached garages.
