Like the video says, immediately contact the U.S. Department of Housing and Urban Development (HUD) if you ever feel excluded from a neighborhood or particular house.
Also, contact HUD if you believe you are being discriminated against on the basis of race, color, religion, sex, nationality, familial status, or disability.
HUD's Office of Fair Housing has a hotline for reporting incidents of discrimination: 1-800-669-9777 and 1-800-927-9275 for the hearing impaired.
