MONTGOMERY COUNTY, MD: "The Montgomery County Council has unanimously approved a bill that requires at least one, single-user restroom be made available regardless of gender in certain public buildings. The new legislation also requires signage designating gender-inclusive restrooms. Bill 4-22, Human Rights and Civil Liberties, Public Accommodations, Gender Inclusive Restrooms, aims to increase accessibility for anyone to use a single-user restroom, regardless of gender, gender identity or expression. Existing law allowed an owner of a business or County-owned building to restrict single-occupancy restrooms to a specific gender.
Other jurisdictions in Maryland and across the nation have successfully implemented similar legislation, including the City of Salisbury, Baltimore City and Howard County in Maryland; the City of Seattle in Washington; California; Austin City in Texas; and the City of Philadelphia in Pennsylvania."
