At the International Association of Plumbing and Mechanical Officials (IAPMO) 88th annual Education and Business Conference in September, the membership made its final recommendations toward development of the 2018 editions of the American National Standard Uniform Plumbing Code (UPC) and Uniform Mechanical Code (UMC). During the Association Technical Meeting Convention, members debated and cast votes to approve or reject all proposed changes for the last time in this code cycle. Membership recommendations will be sent to the Technical Committees for one final vote, and any filed appeals will be heard by the Standards Council in November. The new editions will be released in the first quarter of 2018. IAPMO is calling for formal code proposals toward development of the 2021 editions. The code proposal form may be found at 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 March 16, 2018.
