New regulations will guarantee trans men and women working for the federal government will be able to use bathrooms that align with their gender identity.

The guidelines, posted this week in the Federal Register, affect workers and visitors at the approximately 9,200 facilities operated by the General Services Administration, from federal courthouses to Social Security Administration offices (but not national parks).

“Federal agencies occupying space under the jurisdiction, custody, or control of GSA must allow individuals to use restroom facilities and related areas consistent with their gender identity.”

The EEOC's Chai Feldblum says the new requirements "can change the default for what life is like for federal employees and people who enter federal buildings," adding that rule is of “great significance.”

BuzzFeed News reports:

Transgender people do not need to complete any medical procedure to qualify to use the restroom that aligns with their gender, nor can they be required to show proof of surgery, the bulletin states. They also cannot be restricted to single-occupancy restrooms.

The president previously issued guidelines directing schools that received public funding to accommodate transgender students by allowing them to similarly use facilities that match their gender presentation.

In response, at least 20 states have filed suit against the Obama Administration.
