Transformative Changes in the 2027 International Swimming Pool and Spa Code (ISPSC)
The updates to the 2027 ISPSC, combined with the inclusion of the PHTA/ICC-2 standard, introduce significant and essential improvements designed to enhance safety, health, ease of compliance and operational clarity within the realm of public aquatic facilities.
The International Swimming Pool and Spa Code® (ISPSC®) is a cornerstone for ensuring the safety and health of users in aquatic environments. The 2027 revisions to the code introduce significant updates aimed at enhancing safety, clarity and operational coherence across swimming pools and spas.
These changes respond to evolving industry needs and safety standards, notably aligning more closely with established terminologies and practices.

Refined Definitions for Clarity and Consistency
A central objective of the 2027 ISPSC is the refinement of definitions. In prior editions, certain terminology was not fully aligned with industry standards and other International Codes® (I-Codes®), which could result in ambiguity during interpretation. The updated definitions more precisely distinguish between pool and spa types, and the correlation with related new definitions in other I-Codes allows for a more seamless experience using the collection.
This revision promotes a more consistent framework for recreational water use and contributes to enhanced facility safety.
Updated Fixture Requirements for Public Health
The 2027 ISPSC® recognizes the importance of restroom access at public pools by establishing refined fixture requirements that support public health objectives. These updates address prior shortcomings, where required fixture counts correspond to actual usage patterns potentially affecting hygiene.
The revised provisions standardize requirements across all pool classes, helping ensure adequate restroom facilities for all bathers.
Reorganization of Doors and Gates Regulations
Sections 305.3 and 305.4 have been reorganized to provide a clearer, more unified framework for barrier openings, particularly doors and gates. The revised structure makes key requirements easier to locate while improving safety.
New subsections clarify compliance provisions for doors, gates, and windows and strengthen safety measures around pool areas. This reorganization supports a more focused approach to exterior and interior compliance and improves barrier effectiveness in preventing unauthorized entry.
Inclusion of Angle of Repose Provisions
Given the importance of pool excavation to structural integrity, the 2027 ISPSC introduces a new section addressing the angle of repose. This section establishes safety guidance for excavation activities, including a defined zone into which excavation is not permitted to encroach.
These provisions are intended to mitigate hazards associated with unstable soil conditions and to address an area that was not previously subject to comprehensive regulation.
Surge Capacity and Enhanced Water Management
The 2027 ISPSC clarifies surge capacity requirements to improve management of water displacement during periods of high bather load. It distinguishes between components that contribute to surge capacity and those that do not, including gutters and trenches.
By defining requirements based on freeboard levels, the code strengthens the efficiency of water management systems and supports improved pool water quality and safety.

PHTA/ICC-2 Standard Addition
A significant milestone in the 2027 ISPSC is the incorporation of the ANSI/PHTA/ICC-2 American National Standard for Public Pool and Spa Operations and Maintenance, modeled after the CDC’s Model Aquatic Health Code (MAHC).
With recent budget cuts impacting the MAHC’s development and updates, integrating this standard serves as a vital resource for maintaining operational safety and health in public pools and aquatic venues. It delivers enforceable guidelines on water quality, inspections, hygiene facilities and environmental controls, thus fortifying aquatic safety protocols nationwide.
Core Guidelines and Requirements in PHTA/ICC-2
The PHTA/ICC-2 standard provides enforceable, science-based protocols tailored for aquatic professionals, public health officials and commercial operators.
Key areas covered in the standard include:
Water Quality Parameters
This section specifies exact chemical ranges for essential metrics such as pH, disinfectant levels, total alkalinity and calcium hardness.
Inspections & Permits
Guidelines for schedules and record-keeping related to operating permits, safety equipment checks and routine inspections are outlined to facilitate compliance.
Hygiene Facilities
The standard includes maintenance protocols for essential facilities like bathhouses, locker rooms, showers and restrooms, promoting hygiene and safety.
Indoor/Outdoor Environments
It establishes standards for air quality and ventilation in indoor facilities, along with guidelines for decking and facility boundaries, ensuring overall safety and comfort.
A Step Forward in Pool and Spa Safety
The updates to the 2027 ISPSC, combined with the inclusion of the PHTA/ICC-2 standard, introduce significant and essential improvements designed to enhance safety, health, ease of compliance and operational clarity within the realm of public aquatic facilities.
As the landscape of these facilities continues to evolve, these updates ensure that health and safety regulations effectively address contemporary needs and challenges. By harmonizing construction and maintenance practices, the future of public swimming pools and spas is poised to be safer and more sustainable than ever before.
The ongoing budget constraints faced by the Centers for Disease Control and Prevention (CDC) further highlight the critical importance of adhering to these updated standards to safeguard the health and well-being of all facility users.
By committing to the comprehensive guidelines established in the 2027 ISPSC and the ANSI/PHTA/ICC-2 Standard, stakeholders within the pool and spa community can collaborate effectively toward a standard of aquatic enjoyment and health that is not only safer, but also more accountable and consistent.
