The International Association of Plumbing and Mechanical Officials (IAPMO), publisher of the Uniform Plumbing Code (UPC) and Uniform Mechanical Code (UMC), is calling for formal code proposals toward the development of the 2024 editions of these American National Standard designated model codes.All proposals recommending new text, revised text or the deletion of text must be written in legislative format and clearly state the reason behind the recommendation.No proposals will be accepted after the 5 p.m. PST deadline on Jan. 4,2021. 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 systems. Developed and subsequently republished at the conclusion of each three-year code cycle, the UPC and UMC are designed to provide consumers with safe plumbing, heating, and mechanical systems while, at the same time, allowing latitude for innovation and new technologies.
