The District of Columbia Human Rights Act prohibits discrimination in employment based on an individual's actual or perceived marital status (including domestic partnership and parenthood), family responsibilities, sexual orientation, and gender identity or expression (DC Code Sec. 2-1402.11).
"Marriage" is the legally recognized union of two persons who are otherwise eligible to marry, regardless of gender (DC Code Sec. 46-401 et seq.).
"Domestic partnership" is defined as the relationship between two persons who have registered as domestic partners under the District's registration procedures (DC Code Sec. 32-701).
"Sexual orientation" includes homosexuality, heterosexuality, and bisexuality, by preference or practice.
"Gender identity or expression" is a person's gender-related identity, appearance, expression, or behavior, regardless of the person's assigned sex at birth (DC Code Sec. 2-1401.02).
The Act applies to all employers in the District.
