The 2024 edition of the Uniform Plumbing Code (UPC) represents the most up-to-date standards and best practices in the plumbing industry. This edition is the eighth developed through the ANSI consensus process and is officially recognized as an American National Standard by the American National Standards Institute (ANSI).
The development of this code includes contributions from every sector of the built environment—ranging from consumers, regulatory authorities, installers, service professionals, labor groups, and manufacturers to research organizations, testing laboratories, subject-matter experts, and end users.
The purpose of the UPC is to ensure safe, sanitary, and reliable plumbing systems for consumers, while still supporting innovation and emerging technologies.
