Any owner of a business designed or used for occupancy as a nightclub, dance hall, discotheque, bar or for similar entertainment purposes to which the second paragraph does not apply shall install a system of automatic sprinklers within the building or structure in accordance with the state building code if the business: (1) violates the maximum capacity for such building or structure, as established by a duly recognized inspector of buildings, building commissioner or local inspector of a city, town or district or other duly recognized local inspector or inspector, as provided in chapter 143, 2 or more times during a 12–month period; or (2) violates the maximum capacity of such building or structure by a number greater than 1/2 of such maximum capacity as established by a duly recognized inspector of buildings, building commissioner or local inspector of a city, town or district or other duly recognized local inspector or inspector, as provided in chapter 143.
