Architectural Barriers Act of 1968 and in private buildings by the Americans with Disabilities Act of 1990. No federal legislation relates to provision of facilities for women. The banning of pay toilets came about because women/girls had to pay to urinate whereas men/boys only had to pay to defecate. In many older buildings, little or no provision was made for women because few would work in or visit them. Increased gender equality in employment and other spheres of life has impelled change. Until the 1980s, building codes for stadiums in the United States stipulated more toilets for men, on the assumption that most sports fans were male. In 1973, to protest the lack of female bathrooms at Harvard University, women poured jars of fake urine on the steps of the University's Lowell Hall, a protest Florynce Kennedy thought of and participated in. The first "Restroom Equity" Act in the United States was passed in California in 1989. It was introduced by then-Senator Arthur Torres after several long waits for his wife to return from the bathroom. Facilities for female U.S. senators on the Senate Chamber level were first provided in 1992. Nissan Stadium in Nashville, Tennessee was built in 1999 in compliance with the Tennessee Equitable Restrooms Act, providing 288 fixtures for men and 580 for women. The Tennessean reported fifteen-minute waits at some men's rooms, compared to none at women's rooms. The Act was amended in 2000 to empower the state architect to authorize extra men's rooms at stadiums, horse shows and auto racing venues. In 2011 the U.S. House of Representatives got its first women’s bathroom near the chamber (Room H-211 of the U.S. Capitol). It is only open to women lawmakers, not the public. Regulations Current laws in the United Kingdom require a 1:1 female–male ratio of restroom space in public buildings. The International Building Code requires range of female to male ratio of toilets depending on the building occupancy. Most occupancies require 1:1 ratio, but Assembly uses can require up to 2:1 ratio of female to male toilets. New York City Council passed a law in 2005 requiring roughly this in all public buildings. An advisory ruling had been passed in 2003. U.S. state laws vary between 1:1, 3:2, and 2:1 ratios. The Uniform Plumbing Code specifies a 4:1 ratio in movie theaters. Gender-neutral toilets Gender-neutral toilets are common in some contexts, including on aircraft, on
