Which NFPA standard covers sprinkler systems in low-rise residences?

• A. NFPA 13
• B. NFPA 13R
• C. NFPA 25
• D. NFPA 101

Answer: (B)

The standard designed for low-rise residential sprinkler systems is NFPA 13R. It targets one- and two-family dwellings and other low-rise residential occupancies, usually up to four stories, with a design approach tailored to homes—providing reliable protection while keeping installation practical and cost-effective for residential spaces. This differs from NFPA 13, which covers broader, more complex systems in commercial and larger buildings with more stringent hydraulics and design rules. NFPA 25 deals with inspection, testing, and maintenance, not design, and NFPA 101 is the Life Safety Code addressing overall safety requirements rather than specific sprinkler installation rules.
