The FHEO prohibits any action based on sexual orientation, gender identity, or gender expression. This includes refusing to rent, refusing to negotiate rental rates, setting different terms or rental rates, providing different information about housing availability, and providing different levels of service. Additionally, it is against the law to take any action to interfere with, threaten, or intimidate any renter or prospective tenant filing a Fair Housing Act-related complaint. Source
The FHEO also responds to complaints from renters or prospective renters who believe they have been impacted by housing discrimination. This could be anything from a landlord denying a rental application due to an applicant’s race, disability, national origin, sexual orientation, gender, and any other protected characteristics as defined under the Fair Housing Act or any other relevant civil rights laws. Failing to provide meaningful access to people who do not speak proficient English is also a violation that the office may investigate. Source
