First published by IAPMO in 1945, the UPC governs the installation and inspection of plumbing systems as a means of promotingthe public’s health, safety and welfare. Later published by IAPMO in 1967, the UMC provides the same governance for mechanical (HVAC, combustion, exhaust, refrigeration) systems.
Developed and subsequently republished at the conclusion 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, at the same time, allowing latitude for innovation and new technologies.
IAPMO employs a consensus development process accredited by the American National Standards Institute (ANSI), gathering the largest assembly of plumbing and mechanical experts in the world at its annual education and business conference and technical committee meetings, enabling anyone — members and non-members alike — to propose changes to the code.
IAPMO urges its members and other interested parties to get involved in the code development process to ensure effectiveness in preserving the public’s health, safety and welfare. Installers, plumbing and mechanical officials, the construction industry, engineers and manufacturers all benefit from a cooperative effort in developing codes.
For questions about submitting comments for the UPC, contact Enrique Gonzalez, at (909) 230-5535 or enrique.gonzalez@iapmo.org. For questions about submitting comments for the UMC, contact Taylor Duran, at (909) 218-8126 or taylor.duran@iapmo.org.

IAPMO®, developer of the Uniform Plumbing Code (UPC®) and Uniform Mechanical Code (UMC®), has posted online the 2025 Report on Comments (ROC) for the 2027 editions of these American National Standard-designated model codes. The ROC includes the committee actions as discussed during the May 6-8 technical committee meetings, the electronic ballot results as balloted between May 19-June 16, and the Technical Correlating Committee actions on all comments received for the 2027 editions.
