Which advertisement would violate fair housing laws?

The advertisement stating "Studio condo perfect for singles" would violate fair housing laws because it implies a preference for a specific demographic group, in this case, singles or individuals without families. Fair housing laws prohibit discrimination based on familial status, among other protected characteristics. By suggesting that the property is particularly suited for singles, the advertisement could be seen as excluding families or individuals who do not fit that category, which is against the principles of fair housing that aim to ensure equal opportunity in housing for everyone, regardless of their family structure.

In contrast, the other advertisements focus on features of the properties themselves rather than implying who should or should not live there. They describe the characteristics of the homes and their locations without suggesting that they are more appropriate for specific groups, thus remaining compliant with fair housing regulations.
