The 2015 International Swimming Pool and Spa Code (ISPSC), published by the International Code Council (ICC), establishes comprehensive safety and construction standards for public and residential pools, spas, and hot tubs. Recognized in multiple state and county contractor licensing exams, including those covered by 1 Exam Prep, the ISPSC integrates requirements for circulation systems, barrier protection, water quality, and energy efficiency. It aligns with industry regulations referenced in the Florida Building Code and is essential for contractors pursuing pool building and pool service licenses through the Construction Industry Licensing Board (CILB). This code provides foundational knowledge for trade professionals preparing for contractor, pool, and mechanical licensing exams nationwide.
