In commercial buildings, public toilet facilities must not be located more than how many stories above or below the space required to be provided with toilet facilities?

In commercial buildings, the requirement that public toilet facilities must not be located more than one story above or below the space required to be provided with those facilities is based on accessibility and convenience for users. This guideline ensures that individuals, including those with disabilities, can easily access restroom facilities without having to navigate excessive distances or vertical changes.

This limit is important for practical reasons: if facilities were located further away, it could discourage their use, especially in emergencies or for individuals with mobility challenges. By keeping the distance to a single story, it helps maintain a balance between sufficient restroom availability and accessibility for all patrons or employees in the building. Additionally, this regulation aligns with the principles of good building design that aim to provide safe and efficient environments for occupants.
