Which of the following phrases in a rental ad may be permissible?

This phrase suggests a restriction based on age, which can be problematic under fair housing laws. It may imply discrimination against families with younger children, making it less permissible compared to age-restricted community terms explicitly allowed.

Similar to the previous option, this phrase restricts occupancy based on age, suggesting that no individuals under a certain age can reside in the building. Such restrictions can violate fair housing laws aimed at preventing discrimination against families and younger individuals.

This phrase implies a restriction based on relationship status, which can also be seen as discriminatory. By limiting tenants to couples, it excludes singles and other family structures, raising legal issues under fair housing regulations against discriminatory practices.
