What is PMG?

ICC uses the acronym to refer to ICC’s model codes, standards, services and resources related to plumbing, mechanical, fuel gas and swimming pools/spas topics.

Originally, PMG stood for Plumbing, Mechanical, and Fuel Gas. But with the release of the International Swimming Pool and Spa Code® (ISPSC®) in 2012, it has expanded to include pools and spas.

ICC’s model PMG codes include the IPC, IMC, IFGC and ISPSC. Learn more about each code:

These members of ICC’s family of coordinated codes are used by communities nationwide to protect health, safety and welfare within buildings. Communities chose ICC’s PMG codes because they know ICC offers a superior family of codes, developed through a fair and transparent consensus process.
