2021 International Building Code®

This code - published every three years by the International Code Council - applies to all buildings except detached one- and two-family dwellings and townhouses up to three stories. The 2021 International Building Code contains many important changes that affect building construction, including:

• 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.
