Why It Matters
A protected class is a legally defined category—such as race, religion, or disability—that fair housing laws protect from discriminatory treatment in renting, selling, or financing real estate. Landlords cannot use membership in a protected class as a factor in any housing decision. Violations carry civil penalties, HUD complaints, and private lawsuits.
At a Glance
- 7 federal protected classes under the Fair Housing Act (FHA): race, color, religion, sex, national origin, disability, familial status
- Familial status covers households with children under 18, pregnant individuals, and those in custody proceedings
- Disability protection requires landlords to permit reasonable accommodations and modifications
- Many states and cities add classes: source of income, sexual orientation, gender identity, age, marital status, military status, and more
- Disparate impact doctrine: neutral policies that disproportionately exclude a protected class can violate the FHA even without discriminatory intent
- Violations can be reported to HUD, the DOJ, or filed as private lawsuits
- Maximum civil penalties start at $23,011 for a first offense
- Steering tenants toward or away from neighborhoods based on protected class is illegal
- Advertising language that suggests preference or limitation ("ideal for young professionals") is a violation
- Consistent screening criteria applied to every applicant is the primary compliance defense
How It Works
The Fair Housing Act establishes seven federal protected classes. Any landlord—individual, LLC, or institutional—renting or selling residential property must follow these rules nationwide.
The Seven Federal Protected Classes
1. Race — No discrimination based on race or racial identity. 2. Color — Separately enumerated from race; covers intraracial discrimination. 3. Religion — Cannot refuse to rent based on religious beliefs or practices. 4. Sex — Covers gender-based discrimination, including pregnancy and sexual harassment. 5. National Origin — Country of birth, ancestry, accent, or ethnicity. 6. Disability — Landlords must allow reasonable accommodations (policy changes) and reasonable modifications (physical alterations at tenant expense). 7. Familial Status — Protects households with children under 18, pregnant persons, and those in custody proceedings. No-children policies and arbitrary occupancy caps violate this class.
State and Local Additions
Federal law sets the floor. Most states and many cities add classes: source of income (housing vouchers), sexual orientation, gender identity, age, marital status, military status, and in some jurisdictions criminal history. Always verify which classes apply in your specific market.
Disparate Impact
Intentional discrimination is illegal, but so is a neutral policy that disproportionately excludes a protected class. Landlords must show such a policy is both necessary and the least restrictive means of achieving a legitimate business interest.
Compliance
Apply identical written criteria to every applicant, document every decision with objective evidence, and train all staff and agents. A property manager's statement can expose the owner to liability regardless of the owner's intent.
Real-World Example
Kevin owns a four-unit rental in Columbus, Ohio. His written screening criteria require a credit score of 620+, gross monthly income of 3× rent, and no evictions in the past five years—applied to every application in the order received.
When he declines an applicant, his rejection notice reads only: "Your application did not meet our rental criteria." He does not specify which criterion failed. This keeps the stated reason consistent and avoids giving a rejected applicant grounds to argue the reason was pretextual.
Kevin also confirmed that Columbus has a local ordinance protecting source of income—something Ohio does not require statewide. He updated his criteria to accept housing vouchers before listing the unit.
Pros & Cons
- Building compliant tenant screening criteria around protected class rules makes your process legally defensible from the start.
- Consistent, documented objective criteria is the strongest shield against HUD complaints and private lawsuits.
- The patchwork of federal, state, and local protected classes means landlords in multiple markets need separate compliance checklists for each jurisdiction.
- Disparate impact liability creates exposure without any discriminatory intent—a neutral policy with a statistically uneven effect on a protected class is sufficient for a complaint.
- Source-of-income protection requires accepting housing vouchers in covered jurisdictions, limiting screening flexibility.
Watch Out
Inconsistent application. Approving one applicant while rejecting another with similar qualifications creates the appearance of pretextual discrimination. Document objective reasons for every decision.
Steering. Directing applicants toward or away from units based on protected class is an FHA violation, even when well-intentioned.
Advertising language. Phrases like "quiet building" (coded for no children), "perfect for a single professional," or "ideal for a Christian family" signal unlawful preference. Describe the unit, not the preferred tenant.
Source of income. In jurisdictions that protect source of income, refusing to accept Section 8 vouchers is discrimination. Check your city and state before adding "no vouchers" to your criteria.
Blanket criminal history bans. Categorical exclusions of all applicants with any criminal record can create disparate impact liability under HUD guidance. Use individualized assessment instead of automatic disqualification.

The Takeaway
Protected classes define who landlords cannot discriminate against—from advertising through lease renewal. Federal law covers seven classes; most states and cities add more. Compliance means written, consistently applied criteria and awareness of local additions in every market you operate.
