Discrimination lawsuits are one of the most expensive risks a landlord faces. A single complaint — whether filed by a rejected applicant, a current tenant, or a HUD fair housing tester — can cost tens of thousands in legal fees even if you win. The discrimination landscape extends well beyond the Fair Housing Act: the Equal Credit Opportunity Act, state fair housing laws, ADA regulations, and HUD guidance all create obligations you must understand. This guide covers every discrimination law that applies to landlords and how to comply.

The Fair Housing Act: The Foundation

The Fair Housing Act (FHA) is the primary federal anti-discrimination law for housing. Enacted in 1968 and amended in 1988, it prohibits discrimination based on seven protected classes:

What the FHA prohibits

The FHA prohibits discrimination in all aspects of housing, including:

FHA penalties

Disparate Impact: When Neutral Policies Discriminate

Disparate impact is one of the most important — and most misunderstood — concepts in fair housing law. It means a policy that appears neutral can still be discriminatory if it has a disproportionate effect on a protected class.

Examples of disparate impact

How to defend against disparate impact claims

If a policy has a disparate impact, you can defend it by showing:

  1. The policy is necessary to achieve a substantial, legitimate, nondiscriminatory interest (e.g., ensuring tenants can afford rent, protecting safety)
  2. There is no less discriminatory alternative that would achieve the same goal

The key is to have written, specific criteria that are directly tied to your legitimate business interest — and to apply them consistently.

The Equal Credit Opportunity Act (ECOA)

While the FHA is the primary housing discrimination law, the ECOA also applies to landlords when credit is a factor in rental decisions. The ECOA prohibits discrimination in credit transactions based on:

ECOA requirements for landlords

ECOA record retention is longer than FCRA

The ECOA requires landlords to retain rental applications and screening records for 25 months. The FCRA only requires "reasonable" retention. If you follow the ECOA's 25-month rule, you comply with both laws. Keep applications, screening reports, and decision records for at least 25 months.

State and Local Fair Housing Laws

State and local laws often provide broader protections than federal law. You must comply with all applicable laws, and whichever provides more protection takes precedence. Here are the most common additional protected classes:

Source of income protection (18+ states)

This is the most important state-level protection for landlords to know about. In states with source of income protection, you cannot refuse tenants who use Section 8 vouchers, SSI, SSDI, or other government assistance to pay rent.

States with source of income protection: California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Minnesota, New Jersey, New York, North Dakota, Oklahoma, Oregon, Vermont, Virginia, Washington, plus DC and many cities.

Sexual orientation and gender identity

Federal: HUD's 2021 guidance extends FHA "sex" protection to include sexual orientation and gender identity, following the Supreme Court's Bostock decision.

States with explicit protection: California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Iowa, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Hampshire, New Jersey, New Mexico, New York, Oregon, Rhode Island, Utah, Vermont, Virginia, Washington, plus DC.

Age

Some states protect against age discrimination in housing: Maryland (18+), Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Vermont.

Marital status

Alaska, California, Delaware, Florida, Maryland, Massachusetts, Minnesota, Montana, New Hampshire, New Jersey, New Mexico, North Dakota, Ohio, Oregon, Vermont, Washington.

Military or veteran status

Many states add military status as a protected class: California, Connecticut, Delaware, Hawaii, Illinois, Maine, Massachusetts, Minnesota, New Jersey, New York, Oregon, Rhode Island, Virginia, Washington, plus DC.

Ancestry

Alaska, California, Hawaii, Michigan, Montana, New Jersey, and others protect ancestry as a distinct class from national origin.

Americans with Disabilities Act (ADA)

The ADA applies to public accommodations, which in rental housing means common areas accessible to the public (leasing offices, common rooms, rental offices). While the FHA covers most housing discrimination issues related to disability, the ADA requires:

HUD Guidance on Specific Issues

Criminal history screening (2016 guidance)

HUD issued specific guidance on using criminal records in housing decisions:

Limited English proficiency

HUD guidance states that policies that discriminate based on language proficiency may constitute national origin discrimination:

Domestic violence (2016 guidance)

HUD guidance states that penalizing domestic violence victims (e.g., eviction for noise complaints related to domestic violence, or eviction for police calls) may constitute sex discrimination:

How Fair Housing Testing Works

HUD funds fair housing organizations that conduct "testing" — sending matched pairs of applicants to investigate discrimination. For example:

You may never know if an applicant is a tester. This is why consistent treatment of every applicant is essential — not just for legal compliance, but because any applicant could be a fair housing tester documenting your practices.

Building a Discrimination-Compliant Screening Process

Step 1: Write down your criteria

Step 2: Apply criteria identically

Step 3: Document everything

Step 4: Train yourself and your staff

Step 5: Review your advertising

Discrimination compliance is not optional — it's the law, and the penalties are severe. But compliance isn't just about avoiding penalties. Fair, consistent treatment of all applicants and tenants is simply good business. It attracts quality tenants, prevents complaints, and builds a reputation that makes your rental business sustainable.
