  • New egress requirements for puzzle rooms (also know as escape rooms).
  • New requirements for classroom acoustics in compliance with ICC A117.1
  • Changed requirements for metal composite materials and systems (MCM) installed on the exterior walls of Types I, II, III and IV construction.
  • Additional guidelines on the use of intermodal shipping containers as buildings. 
  • New requirement for automatic sprinkler protection in Group S-2 open parking garages where any fire area exceeds 48,000 square feet.
  • New minimum height requirement for parapets used for aggregate-surfaced roofs to prevent blow-off.
  • New special inspection requirements that address the anchorage and connection of mass timber structural elements.
  • New requirements for the installation of firestop, fire-resistant joint systems and perimeter fire barrier systems in residential-use buildings.
  • New requirements for frost protection for egress doors.

The 2021 International Building Code will soon be adopted by many state agencies.  Order your copy now and be prepared to stay in full compliance.
