Which of the following situations is considered to violate the law?

The situation that is considered to violate the law is that a village must be at least 45 years old to be accepted for Green Acres Retirement. This scenario discriminates against a demographic group based on age. Laws such as the Fair Housing Act protect against discrimination in housing on various grounds, including age. Therefore, establishing a minimum age requirement for a village undermines the principles of equal opportunity in housing and could be considered illegal.

In comparison, the other scenarios do not necessarily violate laws concerning discrimination or fair housing. A background check is commonly required as part of the screening process for applicants and does not discriminate based on protected characteristics. Similarly, requiring residents to be tax-paying citizens is a standard requirement in many programs and generally does not equate to discrimination. Lastly, limiting applications to homeowners can be a policy choice of a program, as long as it is clearly defined and does not infringe upon the rights of protected classes.
