The comfort station, otherwise known as a public toilet, was placed on the National Register of Historic Places on March 13, 1991. It is part of the Mount Rainier National Historic Landmark District, which encompasses the entire park and which recognizes the park's inventory of Park Service-designed rustic architecture. Another comfort station (S-005) situated between the Yakima Park Stockade Group and the Sunrise Lodge is not part of that district but contributes to the Sunrise Historic District instead. S-310 does not.
