The provided sources outline the 2023 Florida Building Code regulations for the installation and calculation of minimum plumbing fixtures in various building types. A primary focus is placed on Exception 2 of Section 403.1.1, which details how to determine fixture counts for multi-user, all-gender facilities by applying the most restrictive gender-based ratios to the entire occupant load. This ensures that the transition to gender-neutral restrooms does not result in a reduction of available facilities, while maintaining strict adherence to accessibility and privacy standards, such as requiring urinals to be placed within stalls. The documents also provide a comprehensive classification table defining requirements for assemblies, businesses, and residential structures, alongside technical specifications for the installation and drainage of specific fixtures like showers, sinks, and emergency stations. Ultimately, these guidelines serve as a mandatory framework for plan reviewers and designers to ensure public health and safety through adequate sanitation provision.
