Which NFPA standard pertains to low-rise residential occupancies?

NFPA 13R is the National Fire Protection Association standard that specifically addresses the requirements for the design and installation of fire sprinkler systems in low-rise residential occupancies, typically defined as buildings up to four stories in height. This standard aims to provide a level of fire protection that is appropriate for these types of structures, ensuring safety and minimizing the loss of life and property in the event of a fire.

NFPA 13R is distinct from other standards like NFPA 72, which deals with fire alarm systems; NFPA 25, which focuses on the inspection, testing, and maintenance of water-based fire protection systems; and NFPA 13D, which also covers sprinkler systems but is specifically tailored for one- and two-family dwellings. Therefore, NFPA 13R is the most relevant choice when considering fire safety measures for low-rise residential settings.
