      1. The dwelling or structure shall be equipped with a residential fire sprinkler system. For a caretaker residence or single-unit dwelling, such a sprinkler system shall be installed to the minimum requirements of NFPA 13D "Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes."
