The 2024 International Codes (I-Codes) introduce significant formatting updates as part of the International Code Council’s (ICC) digital transformation efforts aimed at improving user experience. These changes create a cleaner, more modern appearance while enhancing readability and sustainability.

Key updates include a shift to a single-column text format and updated font styles for better clarity. QR codes now replace traditional margin sidebars and arrows, allowing users to identify code changes more accurately. Table headers and notes are shaded to make them easier to locate, and related content—such as tables and figures—is now grouped directly after the relevant sections for improved navigation.

In addition, users can verify the authenticity of their code books and register them with the ICC to access various incentives.
