Ontario, California – IAPMO® has published the 2027 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 2027 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 2027 UPC and UMC Illustrated Training Manuals (ITM) and Guide to Important Code Changes (GTICC) are also available, offering an additional educational resource designed to support understanding and application of the codes through clear visual interpretation and practical instruction.
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 2027 editions of the UPC and UMC mark the ninth 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:

IAPMO® has concluded technical committee meetings toward the American National Standards Institute (ANSI)-accredited development of the 2027 editions of the Uniform Solar, Hydronics and Geothermal Code (USHGC®) and Uniform Swimming Pool, Spa and Hot Tub Code (USPSHTC®).
IAPMO® has concluded the technical committee meeting toward the development of the 2027 edition of the Water Efficiency and Sanitation Standard (WE•Stand), previous editions of which are American National Standards.
IAPMO® will once again take a leading role in national High-Performance Buildings Week, returning to Washington, D.C., June 2-4. With the event celebrating its 20th anniversary this year, IAPMO will join members of the High-Performance Buildings Coalition (HPBC) on Capitol Hill to advocate for resilient, efficient, and sustainable building practices.
