IAPMO recently completed Technical Committee Meetings toward the proposed 2027 editions of the Uniform Plumbing Code (UPC) and Uniform Mechanical Code (UMC), in-development American National Standards governing the installation and maintenance of plumbing and mechanical systems nationwide. IAPMO’s 2025 Annual Education and Business Conference will take place in September in California.

During the latest meetings, the two committees reviewed and acted on a total of 330 public comments submitted in response to previous proposals to amend the 2024 editions of the Uniform Codes. The UPC® Technical Committee acted on 155 public comments, and the UMC® Technical Committee acted on 175 public comments. Due to compelling discussions on the topics above, the UPC and UMC Technical Committees requested the formation of the 5 task groups for development of the 2030 editions of the codes: UPC Heat Pump Water Heater; UPC Grease Interceptors; UPC Construction Practices for Potable Water Systems; UPC Ecological Sanitation Systems; and UMC Enclosed parking garages and gas detectors.

In accordance with IAPMO’s American National Standards Institute (ANSI) accredited Regulations Governing Committee Projects, balloting of the UPC and UMC technical committees opened on May 19 and will conclude on June 16. The Report on Comments (ROC) for each document will be created from these balloted actions and made available in early August. All consensus body actions will be published in the ROC. 
 
IAPMO gathers the largest assembly of plumbing and mechanical experts in the world at its annual education and business conference and technical committee meetings, enabling anyone, members and non-members alike, to have a voice on proposed changes to the codes. IAPMO’s 2025 Annual Education and Business Conference will take place Sept. 14-18 in Palm Springs, California. Allowable motions during technical committee meetings are governed in accordance with Sections 4-5 of the Regulations Governing Committee Projects. IAPMO® urges its members and other interested parties to get involved in the code development process to ensure effectiveness in preserving the public health, safety, and welfare through fair and balanced development of the Uniform Codes.
