Final answer:
A licensee would be in violation of fair housing laws if they refuse to show properties to a family because of their race, ethnicity, or any other protected characteristic.
Step-by-step explanation:
A licensee would be in violation of fair housing laws if he refused to show properties to a family because of their race, ethnicity, or any other protected characteristic. Fair housing laws, such as the Fair Housing Act in the United States, prohibit discrimination in housing based on factors such as race, color, religion, sex, national origin, familial status, and disability.
For example, if a licensee refuses to show properties to a family because they are African American, this would be considered a violation of fair housing laws. Such discriminatory practices are illegal and can result in legal consequences for the licensee.
