Fair housing for renters: what you're protected from
California fair-housing law protects people in many housing situations from discrimination and harassment based on protected characteristics, including race, religion, national origin, sex, disability, familial status, sexual orientation, gender identity, source of income, and others. Federal and local rules may add protections.
Coverage and exceptions depend on who is offering the housing and whether spaces are shared. Save the listing, messages, application, and any stated reason for denial. Do not assume an unfair experience is legally irrelevant because it involved a room rather than a whole apartment.
For advice about a specific situation, contact a fair-housing agency or qualified lawyer.
