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

• A. NFPA 13D
• B. NFPA 13R
• C. NFPA 20
• D. NFPA 24

Answer: (B)

Low-rise residential occupancies are addressed by a standard that provides sprinkler design criteria specifically for residential buildings up to four stories tall. This standard focuses on protecting living spaces in multifamily housing such as apartments and condos, with provisions tailored to typical residential layouts, water supply expectations, and sprinkler layout patterns that balance reliability with cost. That’s why it’s the best fit here: it targets residential buildings in the low-rise range, unlike standards that cover single-family dwellings (NFPA 13D), general commercial and high-rise or complex occupancies (NFPA 13), or systems involving pumps (NFPA 20) or private service mains (NFPA 24).
