Though the Fair Housing Act applies to most situations, there are some exemptions.
For example, if a dwelling has four or fewer units and the owner lives in one of them, they are exempt from the FHA. However, they would not be exempt under the Pennsylvania Human Relations Act unless the dwelling contained only two units and one was owner-occupied.
Additionally, any single-family housing that’s sold or rented without the use of a broker is exempt from the FHA, as long as the owner is a private individual who doesn’t own more than three such homes at one time. Again, they would not be exempt in the state of Pennsylvania due to the Pennsylvania Human Relations Act.
Housing communities for the elderly are also exempt from the FHA in most cases. In order to not violate the family status provision, it must meet one of several conditions. For instance, HUD must have determined that it’s specifically designed for and occupied by elderly occupants under a federal, state or local government program. Alternatively, it can be 100% occupied by people age 62 or older.
Another option is that the community houses at least one person age 55 or older in at least 80% of the occupied units. The property must also have a policy demonstrating that the intent of the community is to house people age 55 or older.
Finally, religious organizations and private clubs are allowed to give preference to members as long as they don’t discriminate in their membership.
