International Building Code, 2021

The International Building Code, 2021 Edition, is the primary model code used in contractor licensing exams for commercial construction, supporting exam-vendor domains that address structural design, fire and life safety, means of egress, building-envelope systems, accessibility, interior finishes, mechanical and electrical coordination, and construction types. This edition provides the comprehensive regulatory framework required for code-compliant commercial buildings and serves as a core reference for contractors navigating open-book testing environments governed by state licensing authorities.

The 2021 International Building Code applies to all buildings except detached one- and two-family dwellings and townhouses up to three stories.
