You asked the following question: “Under Section for closets and pantries specifies that sprinklers are not required in closets less than 24 sq. ft. with the least dimensions not greater than 3 ft in hotels and motels, therefore it is assumed that sprinklers are required in closets of new apartment buildings as they are not under current hotel and motel category.
