Discrimination in housing based on familial status is a violation of:

Discrimination in housing based on familial status is indeed a violation of the Fair Housing Act. This legislation prohibits discrimination in housing practices based on several protected classes, which include race, color, national origin, sex, disability, and familial status, among others. Familial status specifically protects individuals with children under the age of 18 living with them, as well as pregnant individuals and those in the process of obtaining custody of a child.

The Fair Housing Act was established to ensure that housing is accessible to all, regardless of their family composition. The inclusion of familial status as a protected category signifies the law's commitment to preventing discrimination that might restrict families from living in certain areas or obtaining housing based on the presence of children.

Other acts mentioned, such as the Americans with Disabilities Act, focus primarily on accessibility and accommodations for individuals with disabilities. The National Housing Act pertains to different aspects of housing finance and insurance, while the Home Mortgage Disclosure Act requires financial institutions to maintain and disclose data on mortgage loan applications but does not address discrimination based on familial status. Thus, these acts do not relate to the specific issue of familial status discrimination in housing.
