Which of the following is not an exemption to fair housing law?

The choice indicating that the sale of a single-family home by an owner who owns five residences is not an exemption to fair housing law is correct due to the specific provisions in the Fair Housing Act. This act allows certain exemptions for small-scale landlords and specific situations, but it establishes limits based on the number of properties owned.

In this case, the Fair Housing Act typically permits owners of a single-family home to sell without adhering strictly to the fair housing laws if they own three or fewer properties. However, if an owner has five residences, they are not classified under those exemptions, as they have exceeded the threshold that allows for an exemption to apply. Therefore, such a sale must comply with fair housing regulations to ensure that the transaction is free from discriminatory practices.

By understanding this context, it becomes clear why this situation does not qualify as an exemption under fair housing laws, and it reinforces the need for compliance when more than a specified number of residential units are owned.
