West Hollywood plans to require gender-neutral restrooms to, among other reasons, accommodate new ideas of gender identity.
A law that takes effect Thursday says a business or public place with only one stall can't restrict it to a specific sex either by signage or fixtures.
Existing businesses have 60 days to make changes, and the measure doesn't apply to restroomswith more than one stall.
The Los Angeles suburb, which has a sizeable gay and transgender population, says the ordinance is aimed at helping people whose "gender identity" falls outside of traditional norms.
But it says the measure also will help the disabled, people with children of a different gender, and people who've had to queue up for the men's or women's room when the opposite-sex stalls remain empty.
