The NSSA prefers to use the terminology Community/Commercial when referring to tornado shelters that are used for public and private use by businesses (not Residential use) as defined in the ICC/NSSA 500 –2014 Standard and the FEMA P-361 criteria for Community Tornado Shelters. The term Community/Commercial best describes the real world applications for non-residential tornado shelters.
