You may expect all residents to abide by the lease and community rules, and you may take action against anyone who fails to do so. Fair housing law bans discrimination against members of protected classes, but it doesn’t excuse residents from following the rules, regardless of their race or any other protected characteristic.
Don’t let your fear of a fair housing claim prevent you from applying your policies fairly and consistently. If action is required, don’t fail to act because you’re afraid the resident will file a fair housing complaint against you. Just talk to your attorney first to make sure that all of your community’s actions are documented and justified.
