NFPA 13D, Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, features up-to-date criteria addressing every aspect of sprinkler design and protection, water supplies, equipment, and placement in one- and two-family dwellings, manufactured homes, and townhouses.

Installers and contractors need the latest edition of this standard to address different types of construction, work with the latest technologies, and help reduce fire risks. The standard applies to one- and two- family dwelling units and manufactured homes to allow for the installation of cost-effective fire sprinkler systems in these types of residential occupancies.
