Which NFPA standard covers the installation of sprinkler systems in one- and two-family dwellings and manufactured homes?

• A. NFPA 13-2013
• B. NFPA 13R-2013
• C. NFPA 25-2014
• D. NFPA-13D-2013

Answer: (D)

Residential sprinkler installations follow a standard that is tailored to homes, offering simpler design rules and requirements suitable for dwellings. For one- and two-family houses and manufactured homes, the standard that directly covers design and installation of automatic sprinkler systems is NFPA 13D. This standard focuses on the specifics of residential occupancies, setting expectations for system layout, water supply considerations, and installation practices appropriate for homes, rather than the broader, more complex rules that apply to commercial or multifamily buildings. Other standards in the list serve different purposes: NFPA 13 targets general design and installation for many occupancies (often commercial or larger-scale), NFPA 13R covers residential occupancies up to four stories but not manufactured homes, and NFPA 25 deals with inspection, testing, and maintenance rather than initial installation. So NFPA 13D is the one that matches the question’s scope.
