WASHINGTON (AP) —  President Obama signed on Friday a bill into law that require baby changing stations in both men's and women's restrooms in federal buildings. 

The law is called Bathrooms Accessible in Every Situation Act, according to Congress.gov.

Congress sent legislation on September 29 to President Obama to require baby changing stations in both men's and women's restrooms in federal buildings that are open to the public. Those buildings include some courthouses, post offices and Social Security offices.

Under the bill, the buildings required to have at least one baby-changing facility on each floor. The legislation requires the changes within two years, and makes some exceptions for situations in which it would be cost-prohibitive.

The legislation was passed by voice vote in the Senate after passing the House last week on a vote of 389-34.
