The International Association of Plumbing and Mechanical Officials has been protecting the public’s health and safety for more than eighty five years by working in concert with government and industry to implement comprehensive plumbing and mechanical systems around the world.

As a membership-based association, IAPMO is proud to utilize an open consensus process in the development of our flagship Uniform Plumbing Code® and Uniform Mechanical Code®. These codes are established through scientific research, debate, and analysis, strengthening our position at the forefront of the plumbing and mechanical industries.

The IAPMO Group is a complete service organization, providing code development assistance, industry-leading education, plumbing and mechanical product testing and certification, building product evaluation and a manufacturer-preferred quality assurance program. Each component of the IAPMO Group works toward playing an integral part in protecting the health of people everywhere.
