IAPMO first developed the USPSHTC in March 1967. The provisions of this code apply to the erection, installation, alteration, repair, relocation, replacement, addition to, use, and maintenance of aquatic recreation facilities, swimming pools, spas, or hot tub systems.
The USHGC was first developed in September 1976. The provisions of this code apply to the erection, installation, alteration, addition, repair, relocation, replacement, addition to, use or maintenance of solar energy, water heating, appliances intended for space heating or cooling, swimming pool heating, process heating, geothermal and hydronic systems, snow and ice melt systems and use of any solar energy systems.
The USHGC and USPSHTC are produced using a consensus process accredited by the American National Standards Institute (ANSI) and will be self-designated as American National Standards upon completion, as IAPMO is an ANSI Audited Designator.
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 Castle Rock, Colorado, town council has approved the adoption of IAPMO’s Uniform Plumbing Code (UPC®) Appendix M — the Water Demand Calculator® — as an alternative methodology for sizing water pipes in single- and multifamily buildings. The Castle Rock Town Code has been amended to require the use of the Water Demand Calculator for sizing water service lines and internal plumbing supply lines.
