Committee Action Hearings – Group B #2

October 22–30

This year’s code hearings offer code officials, architects, builders, structural engineers, fire, residential and existing building professionals as well as those responsible for the administration of the International Codes® (I-Codes®), the opportunity to provide input on proposed code changes to the Group B I-Codes. The code hearings are free to attend and open to the public. Registration is required.

The code development process for the 2027 I-Codes introduces a restructured process that began in 2024 with two Committee Action Hearings for Group A Codes, followed in 2025 by two Committee Action Hearings for Group B Codes. In April 2026, there will be combined Group A and B Public Comment Hearings with a combined Online Governmental Consensus Vote in May 2026. Please refer to the 2024/2025/2026 ICC Code Development Schedule for details on code groups and important deadlines.
