New York lays out transgender protection guidelines

New York City has warned landlords, employers and businesses they could be running afoul of the law by purposely calling a transgender woman "him" or "Mr." when she prefers a female title and pronoun, or by barring her from using a women's restroom.

New guidelines detail the legal protections of transgender and gender-nonconforming New Yorkers and what constitutes discrimination under the city's Human Rights Law, the New York City Commission on Human Rights said on Monday.

Some 25,000 transgender and gender nonconforming people live in New York City, where discrimination based on gender identity and expression has been illegal since 2002.
