The 2021 International Building Code (IBC) applies to all buildings except single-family homes and townhouses up to three stories. This edition introduces several important changes:
-
Puzzle rooms (escape rooms) now qualify as special entertainment venues. They must follow Section 411 and meet specific exit requirements.
-
When counting monitoring areas, each section separated by one or more firewalls counts as a separate building.
-
In Group E facilities, classrooms up to 20,000 cubic feet must meet improved acoustics standards according to ICC A117.1.
-
Requirements for Type I, II, III, and IV exterior wall composite metal materials (MCM) have been simplified, and sprinklers have been removed.
-
Provisions now explicitly address the use of intermodal shipping containers as structures, supplementing existing IBC rules.
