ICC 500-2014 Shelter Standards

Tornado shelter construction guidelines protect building occupants from nature's fiercest storms.

Beginning in 2002 the International Code Council and the National Storm Shelter Association started working to create the first Standard for the Design and Construction of Storm Shelters, to be released as ICC 500 – 2008.  ICC 500-2008 was first referenced in the 2009 IBC as the standard for constructing a shelter in a public facility. The language remained in place for the 2012 edition of the IBC providing guidance for voluntary construction of shelters, but neither edition contained mandatory requirements for construction of shelters. 

The 2015 Edition of the International Building Code brought two significant changes: First being the adoption of the new edition of ICC 500–2014, and secondly the mandatory requirements for shelter construction.  ASSA ABLOY Tornado Resistant Assemblies are UL classified to the following standards and test method:

  • ICC 500-2014:  The International Code Council (ICC) 500-2014 is a referenced standard in the 2015 International Building Code® (IBC) and the 2015 International Residential Code® (IRC). Buildings or spaces designated for use as a shelter from tornadoes and/or hurricanes within the scope of the IBC and IRC must conform to the requirements in ICC 500.
