It is unlawful for a place of public accommodation to designate a single-occupancy toilet facility as for use only by members of one sex. The toilet facility may be identified by a sign, but the sign cannot indicate that only individuals of a particular sex may use the facility. For the purposes of this subsection, a "single-occupancy toilet facility" is a restroom for use by one person at a time, or for family or assisted use, and that has an outer door that can be locked by the occupant.
A single-occupancy toilet facility may be identified as accessible by individuals with disabilities consistent with the accessibility requirements below.
