The Technical Committee Meeting Monographs contain every code change proposal submitted for the 2027 editions of the UPC and UMC as part of the ANSI-accredited consensus code development process employed by IAPMO.
What do the 3-model codes, UPC (Uniform Plumbing Code), IPC (International Plumbing Code) and NSPC (National Standard Plumbing Code), have to say on the subject?
There were 347 changes proposed to the Uniform Plumbing Code, and 349 code changes proposed to the Uniform Mechanical Code. While the numbers seem high, they are actually consistent with previous code change cycles.
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.
