Which NFPA standard covers the installation of sprinkler systems in low-rise residential occupancies?

The installation of sprinkler systems in low-rise residential occupancies is specifically addressed by NFPA 13R. This standard focuses on the design and installation of sprinkler systems in residential settings that are generally three stories or less in height, which is characteristic of low-rise structures. NFPA 13R allows for certain simplifications in design and installation compared to NFPA 13, which is the standard for more comprehensive sprinkler system installations in commercial and high-rise settings.

The rationale behind NFPA 13R is to provide a cost-effective means of improving fire safety in residences while still ensuring adequate protection for occupants. This standard facilitates the use of an automatic sprinkler system in residential environments where conventional full coverage might not be practical or necessary.

Other standards mentioned, such as NFPA 13, primarily deal with broader and more complex building types and do not focus specifically on the residential context. Meanwhile, NFPA 20 addresses the installation of stationary pumps for fire protection and is not directly related to sprinkler system design and installation for low-rise residential occupancies. NFPA 13D covers one- and two-family dwellings and provides guidelines for the installation of sprinkler systems specifically designed for those structures, but it is not applicable to the broader low-rise category that includes more multif
