The Significant Changes to the 2012 International Codes series has been developed by the International Code Council and published by Cengage Learning to assist code officials, architects, engineers and other construction professionals transitioning from the 2009 to the 2012 editions of the International Codes.

The series offers a comprehensive yet practical analysis of hundreds of the most critical changes from a very active code development cycle. Each color publication contains:

• revised code text.
• a summary of each change listed.
• in-depth change analysis.
• a detailed photo, illustration or table for each change to deepen understanding.
