What advertising language violates the Fair Housing Act?

The Fair Housing Act prohibits advertising that indicates a preference, limitation, or discrimination based on any protected class. Prohibited language includes phrases like "perfect for young couples," "Christian neighborhood," "no children," "English speakers only," or "ideal for singles." Even descriptions of the neighborhood rather than the property can violate the law if they signal a preference based on protected characteristics. HUD guidelines specify that advertising should describe the property, not the desired occupant. Using human models in advertising should reflect diversity.
