    IAPMO Solicits Proposals for 2024 USHGC, USPSHTC

    The International Association of Plumbing and Mechanical Officials (IAPMO<sup>®</sup>), developer of the Uniform Solar, Hydronics and Geothermal Code<sup>®</sup> (USHGC) and Uniform Swimming Pool, Spa, and Hot Tub Code<sup>®</sup> (USPSHTC) , is calling for formal code proposals toward the development of the 2024 editions of these American National Standard designated model codes.

    The code proposal form, as well as proposal instructions and background on IAPMO’s ANSI-accredited consensus process, can be found HERE.

    All proposals recommending new text, revised text, or the deletion of text must be written in legislative format and clearly state the reason behind the recommendation.

    No proposals will be accepted after the 5 p.m. PST deadline on March 4, 2022.

    IAPMO first developed the USPSHTC in March 1967 and the USHGC’s predecessor, the Uniform Solar Energy Code, in September 1976. The provisions of these codes apply to the erection, installation, alteration, repair, relocation, replacement, addition to or maintenance of any solar energy, hydronic heating/cooling, swimming pool, spa or hot tub system. These codes are produced using a consensus process accredited by ANSI and will be self-designated as American National Standards upon completion of the development cycle, 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.

    For questions about submitting proposals for the USHGC, contact Taylor Costea, USHGC liaison, at (909)218- 8126 or taylor.costea@iapmo.org.

    For questions about submitting proposals for the USPSHTC, contact Enrique Gonzalez, USPSHTC liaison, at (909) 230-5535 or enrique.gonzalez@iapmo.org.
