The Pool and Hot Tub Alliance (PHTA) and the International Code Council (ICC) announced the American National Standards Institute (ANSI) approval and publication of ANSI/PHTA/ICC-5 2025 American National Standard for Residential In-Ground Swimming Pools (PHTA-5).
The updated PHTA-5 standard outlines requirements for the design, equipment, operation and installation of new and remodeled residential in-ground swimming pools. It applies to permanently installed pools intended for noncommercial use by up to three owner families and their guests, with a water depth greater than 24 inches (61 cm).
“The PHTA-5 standard is an indispensable guideline for so many PHTA members and serves as an important tool for the industry as a whole,” says Sabeena Hickman, CAE, president and CEO of PHTA. “Thanks to the dedicated PHTA-5 Standard Writing Committee volunteers and subject matter experts, this revised standard will increase the safety and enjoyment of residential in-ground pools for years to come. PHTA is also thankful to have had the ICC as a strong partner and collaborator throughout this process.”
The revised PHTA-5 standard introduces a new section addressing non-diving pools, specifying that certain parts of the standard apply only to pools intended for diving. This addition is intended to provide clearer construction guidelines for non-diving pools and support safer pool design.
Additional content for circulation system pipe material standards and circulation system fittings standards was added, and requirements for barriers around the pool are now included. The revisions also address egress requirements in vanishing edge catch basins.
“Enhancing swimming pool safety requires a proactive approach to updating codes and standards in step with new insights and innovations,” says Lisa Reiheld, ICC PMG technical resources director. “By continuously refining these guidelines, we not only address emerging risks but also strengthen our commitment to safeguarding public health.”
Federal, state, local and international authorities, as well as industry members and consumers, recognize the need for modern, up-to-date standards governing the design, construction, alteration, repair and maintenance of swimming pools, spas, hot tubs, aquatic facilities and other water-containment vessels, according to the alliance. Part of the ANSI/PHTA standards development process includes regular review of existing standards to ensure this need is met. The updated PHTA-5 standard outlines specific criteria for the design, equipment, installation and use of residential in-ground swimming pools
This standard applies to pool builders, installers, building code officials, local municipalities and consumers who wish to enjoy this type of pool.
