Which of the following advertisements for room rental would be considered legal?

The statement that a room rental advertisement for "female only" is legal is based on the legal constraints surrounding housing, particularly regarding discrimination laws. The Fair Housing Act prohibits discrimination based on sex, among other characteristics. However, there are specific scenarios where a housing provider may legally limit occupancy based on sex, often when the housing is shared and involves shared living spaces, such as in the case of some types of room rentals.

While it may be legal in certain contexts, such as with a landlord offering a shared living situation where personal privacy and safety concerns are considered, advertisements that specify gender can be sensitive. It is important for potential landlords to understand the nuances of the law and local fair housing regulations to ensure compliance.

In contrast, advertisements that specify "college students only" may violate fair housing provisions concerning familial status, while requiring applicants to be employed could potentially lead to discrimination against certain individuals. "No pets allowed" is generally permissible, as pet policies are typically within the rights of the landlord to decide, provided they comply with any applicable state or local laws regarding service animals.
