The International Codes (I-Codes), developed by the International Code Council, are a family of fifteen coordinated, modern building safety codes that help ensure the engineering of safe, sustainable, affordable and resilient structures.

The I-Codes are the most widely accepted, comprehensive set of model codes used in the United States. All fifty states, the District of Columbia, and many other countries have adopted the I-Codes at the state or jurisdictional level.

The Standards Development Process

As is the case with it's codes, the Code Council adheres to openness and transparency in our standards development process. All Code Council standards committee meetings are open to the public. Any interested party can participate in committee meetings and can be considered by the committee for membership on any work-group that the committee creates.

The International Code Books

The Code Council has made the International Codes available as a comprehensive and coordinated set of publications including:

Plumbing, Mechanical, Fuel Gas and Swimming Pool Codes (PMG)

The Code Council has historically used the acronym PMG to refer to its model codes, standards, services and resources related to plumbing, mechanical, fuel gas. With the release of the International Swimming Pool and Spa Code (ISPSC) in 2012, it has expanded to include swimming pools and spa topics.
