Which occupancy includes the use of a building for storage that is not classified as hazardous?

The correct classification for a building used for storage that is not considered hazardous is Group S. This occupancy group is specifically designated for storage facilities that store non-hazardous materials. This means that the building primarily functions as a space for keeping goods without the risk factors associated with hazardous substances.

In context, Group H refers to hazardous materials, which is not applicable here since we're discussing non-hazardous storage. Group M deals with mercantile uses, generally associated with the retail space and sales, not primarily for storage. Group U encompasses structures for utility and miscellaneous uses, which would not specifically address a dedicated storage purpose. Therefore, Group S is the appropriate classification, focusing on non-hazardous storage scenarios.
