What is NFPA 13R primarily used for?

NFPA 13R specifically addresses the design and installation of sprinkler systems in residential occupancies that are up to four stories in height. This code is focused on providing life safety and property protection for smaller, multistory residential buildings, such as apartment complexes and condominiums, which typically accommodate a limited number of residents and have different risks compared to larger commercial or industrial spaces.

The standards set forth in NFPA 13R simplify some of the requirements found in NFPA 13, which is used for larger commercial buildings and high-rise structures, allowing for a more efficient and cost-effective approach to fire protection in lower-height residential settings. This code recognizes the different hazards associated with residential occupancies and tailors the sprinkler system requirements accordingly, making it suitable for the specific needs of such properties.
