The IAPMO Codes Portal connects the industry with the IAPMO code development process. 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. Installers, plumbing and mechanical officials, the construction industry, engineers, and manufacturers all benefit from a cooperative effort in developing codes.
The IAPMO Codes app provides mobile access to IAPMO's published codes, such as the Uniform Plumbing Code (UPC), Uniform Mechanical Code (UMC), and others. It allows users to view their purchased code books, make annotations and voice recordings, and access code-related information, even offline. The app also facilitates engagement with the code development process, including access to timelines, notifications, and contact information for technical staff.
