Separate sex toilet room facilities are not required in which type of facilities?

Separate sex toilet room facilities are not required in specific situations, such as dwelling units, sleeping units, and facilities with a maximum occupant load of 15 or fewer. This encompasses a broader range of scenarios where it is not necessary to provide separate restrooms for different sexes.

In dwelling units, such as private homes or apartments, it's typical for the design to include a single toilet facility that can accommodate all occupants regardless of sex.

In sleeping units, like dormitories or other communal housing options, the same principle applies. Often, these units may feature communal restrooms, reducing the need for separate facilities while ensuring safety and privacy.

When it comes to facilities with an occupant load of 15 or fewer, the code allows such flexibility in restroom facilities due to the smaller number of people using the space. This helps streamline design and construction processes without compromising the usability of restrooms.

By encompassing all these types of facilities, it is clear that the requirement for separate facilities does not apply universally, and the option stating A through C correctly identifies this flexibility in regulations.
