Which act prohibits discrimination in housing?

The Fair Housing Amendments of 1988 are a significant piece of legislation that expanded upon the original Fair Housing Act of 1968. While the amendments enhance protections against discrimination in housing, the original act is the foundational law that prohibits housing discrimination based on race, color, religion, sex, or national origin.

The Fair Housing Amendments specifically added protections against discrimination based on disability and familial status, thus broadening the scope of the original Act. This means that while the amendments are critical and build upon the original law, the Fair Housing Act of 1968 is the principal act that laid the groundwork for these protections.

So, while the amendments are important for the expansion of discrimination protections, the question is referring to the act that initially established the prohibition of discrimination in housing. This detail is crucial for understanding the correct answer and the framework of housing discrimination laws in the United States.
