Ontario, Calif. – The International Association of Plumbing and Mechanical Officials (IAPMO®) has published the 2024 editions of the Uniform Plumbing Code® (UPC) and Uniform Mechanical Code® (UMC) in both hardcopy and electronic versions, completing a three‐year consensus development cycle accredited by the American National Standards Institute (ANSI).
Significant changes to the UPC include:
Significant changes to the UMC include:
The 2024 Uniform Codes will once again be available electronically, meaning that if someone is working from home or in the field and left the code book at the office, it is accessible from a computer or mobile device.
The Uniform Codes are developed using IAPMO’s ANSI-accredited consensus development procedures. This process brings together volunteers representing a variety of viewpoints and interests to achieve consensus on plumbing and mechanical practices. The 2024 editions of the UPC and UMC mark the eighth time these codes have been developed in this manner. IAPMO urges its members and other interested parties to get involved in the process to ensure effectiveness in preserving the public’s health, safety, and welfare through fair and balanced development of its codes and standards. Installers, plumbing and mechanical officials, the construction industry, engineers, and manufacturers all benefit from a cooperative effort in developing codes.
Introduced in Los Angeles in 1928 and formally published as the Uniform Plumbing Code in 1945, the UPC is developed to govern the installation and inspection of plumbing systems as a means of promoting the 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.
The public at large is encouraged and invited to participate in IAPMO’s open consensus code development process. A code development timeline and other relevant information are available at IAPMO’s website.
The 2024 UPC and 2024 UMC may be purchased through the IAPMO bookstore.
