First published by IAPMO in 1945, the UPC governs the installation and inspection of plumbing systems as a means of promoting the health, safety and welfare of the public. Later published by IAPMO in 1967, UMC provides the same control for mechanical (HVAC, combustion, exhaust, cooling systems). Developed and republished at the end of each three-year code cycle, the UPC and UMC are designed to provide consumers with plumbing, heating and mechanical systems that meet all applicable standards while allowing room for innovation and new technology.

IAPMO uses a consensus development process accredited by the American National Standards Institute (ANSI), which brings together the world’s largest assembly of plumbing and mechanical experts at its annual educational and business conference and technical committee meetings, enabling everyone – members and non-members alike — to propose changes to the code.

IAPMO encourages its members and other interested parties to engage in the code development process to ensure effectiveness in preserving the health, safety and welfare of the public. Installers, plumbing and mechanical officials, the construction industry, engineers and manufacturers all benefit from working together to develop codes.
