This video answers the question: What are the differences between the sprinkler systems covered by NFPA 13, Standard for the Installation of Sprinkler Systems, and NFPA 13D, Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, and what are the purposes of these sprinkler systems?
The main focus of NFPA 13D is on life safety, while NFPA 13 applies to both property protection and life safety. The intention behind NFPA 13D is to make the system cost effective to allow installation in more homes.
From your personalized NFPA LiNK dashboard, first compare the titles of each code. NFPA 13D, 2022 edition, focuses on one- and two-family dwellings and manufactured homes. NFPA 13, 2022 edition, can be applied more broadly.
For more details, look at the “Purpose” section of each code. Open NFPA 13 to Chapter 1 and select Purpose. Add subsection 1.2.1 to your reference pane for side-by-side comparison with NFPA 13D.
