Consensus Committee on Storm Shelters
The primary responsibility of this committee is for minimum requirements to safeguard the public health, safety and general welfare through the design, construction and installation requirement for storm shelters. For more information on the ICC procedures for developing standards, please refer to the ICC Consensus Procedures.
The committee has elected to place ICC 500 under continuous maintenance in order to keep the standard up to date with changing developments in the field. Under a continuous maintenance schedule, the consensus body considers recommended changes to any part of the document. The Code Council accepts public comments and proposals for this Standard on a continual basis and during regular calls for comment. Comments and proposals submitted on ICC Public Comment and Proposal Forms may be submitted to the committee secretariat at kpaarlberg@iccsafe.org.
Periodically check ICC's Call for Committee notices to solicit new applicants as openings on the committee occur.
