Las Vegas, NV — Southern Nevada Building Officials this month led a group of area jurisdictions in adopting the 2024 editions of the Uniform Plumbing Code (UPC®) and Uniform Mechanical Code (UMC®), ensuring Southern Nevadans continue to be guarded by the protections of IAPMO’s flagship documents.
The Silver State jurisdictions announcing adoptions this month are:
All jurisdictions can continue to utilize the 2018 editions while phasing in the 2024 editions of the Uniform Codes from the adoption dates and solely utilize the 2024 editions after the effective dates.
“Southern Nevada is proud to lead the way in adopting the 2024 Uniform Plumbing Code and Uniform Mechanical Code,” said Mike Cunningham, chair of the Southern Nevada Building Officials. “These updates reflect our ongoing commitment to safety, sustainability, and innovation in the built environment. By staying aligned with the latest standards, we’re ensuring Las Vegas continues to grow responsibly and resiliently.”
With the addition of Appendix M, Peak Water Demand Calculator®, the 2024 UPC is the only national model plumbing code with significant updates for water pipe sizing in buildings since the development of Hunter’s Curve more than 80 years ago. It is the result of a multiyear, IAPMO-led effort to develop a new statistically based pipe sizing method stemming from a need to address profound water safety and wasted water and energy concerns due to oversized water supply pipes in homes and buildings.
“Southern Nevada continues to lead by example, demonstrating a clear commitment to safeguarding public health and supporting sustainable development through the adoption of the 2024 Uniform Codes,” said DJ Nunez, IAPMO executive vice president of Field Services. “By embracing these forward-looking codes, jurisdictions across the region are ensuring their communities benefit from the most advanced, science-based standards available. This leadership not only protects residents today but also builds a stronger, more resilient future for Southern Nevada.”
The UPC requires accredited third-party certification of drinking water treatment devices, fixtures, and components to the relevant American National Standards. The updates within the 2024 UPC are aligned with meticulous and rigorously tested recommendations throughout the plumbing industry. Updates that address the evolving water landscape in Southern Nevada and beyond include:
Significant changes to within the 2024 UMC include:
