2021 International Plumbing Code
A modification to Section 403.2 (Multiple-user Nonseparated Toilet Facilities) states that designs for multiple-user facilities serving both sexes are possible.
Exception 5 provides an allowance for single-user toilet rooms to not be designated by sex. However, for 2021, Section 403.1.2 requires that single-user toilet facilities not be designated by sex, making this exception unnecessary.
Exception 6 introduces the new concept of multiple-user toilet facilities designed to serve both sexes. Similar to the new concept introduced in Section 403.1.1 (multiple-user toilet facilities to serve all genders), this exception allows multiple-user facilities to be labeled for use by both sexes (male/female). As Section 405.3.4 was not changed for the 2021 edition, multiple-user separate sex toilet facility designs that were compliant with the 2018 code edition could comply with this exception, provided that any urinals are in stalls.
