New Jersey has officially adopted the 2024 New Jersey Edition of the National Standard Plumbing Code (NSPC) to serve as the plumbing code for the Garden State.
The Division of Codes and Standards, which is part of the state’s Department of Community Affairs, adopted the 2024 NSPC with state-specific amendments on August 17.
The 2024 NSPC Illustrated New Jersey edition provides the latest information about common materials, fixtures, devices, and equipment systems used or installed in plumbing systems. The NSPC Illustrated New Jersey edition contains revisions that have been included to promote sustainable plumbing practices. This new edition is printed in the popular illustrated format, with comments and illustrations clearly shown as supplemental information. The illustrations and supplementary notes make it an indispensable training tool.

“IAPMO is honored that New Jersey will continue to be served by our National Standard Plumbing Code,” IAPMO CEO Dave Viola said. “The NSPC has protected the health and safety of New Jersey’s communities since 1977, and this 2024 edition brings the latest advances in affordability, sustainability, and modern materials to the state’s plumbing systems. We remain committed to supporting New Jersey’s code officials and industry professionals with the resources and training they need to put this code into practice.”
Designed to ensure the proper installation of plumbing systems, the NSPC provides local and state governments, code administrative bodies, and the industry with a modern code to protect public health, safety, and welfare.
To keep the code current and viable with input from all interested parties, the NSPC Committee—comprised of licensed contractors, engineers, inspectors, and manufacturers—reviews the code annually and updates it on a three-year cycle.
First published in 1973, the NSPC is designed to ensure the proper installation of plumbing systems, providing local and state governments, code administration bodies, and the industry with a modern code to protect health and promote safety.
