What building code are you under?

t’s time to reconsider the design of public restrooms. The last major change in public restroom design took place 30 years ago with California’s 1987 Restroom Equity Act, which prompted “potty parity” bills in many jurisdictions as well as changes in building code aimed at equalizing restroom wait times for men and women rather than providing an equal amount of square footage or number of fixtures. Architects crunched the numbers, revised the fixture calculations, and started providing more facilities for women in an effort to achieve equity instead of equality.
“and somehow women are still disproportionately waiting in line.”
A 2015 Verizon survey found that nearly 90 percent of respondents admitted to using their phones in the restroom, which could be responsible for an increase in restroom wait times, and their exposure to fecal bacteria.
