In what situation can an apartment refuse to allow pets?

The correct response highlights that service animals, which are trained to assist individuals with disabilities, are protected under the law and typically cannot be denied access to housing, including apartments. This is grounded in the Fair Housing Act, which mandates that landlords must allow service animals, regardless of their pet policy. Service animals are not classified as pets, as their primary purpose is to provide assistance to their owners, thus exempting them from restrictions that may apply to other types of animals.

In contrast, options that specify a certain breed, classify animals as companion animals, or concern the weight of the pet do not have the same legal protections. Landlords may implement pet policies based on breed restrictions due to perceived risks or insurance requirements, and they may also have rules regarding the size or weight of pets. Companion animals, which may provide comfort but are not trained to assist with disabilities, do not carry the same legal rights as service animals. Therefore, while certain conditions may allow an apartment to refuse pets, service animals stand apart due to the legal requirements set forth for their protection.
