Criminal Background Checks and Fair Housing: The Disparate Impact Rule Explained

Running a criminal background check on a rental applicant seems like common sense. But a policy that automatically denies anyone with a criminal record could violate the Fair Housing Act, even if you have the best intentions. After reading this guide, you will understand the legal concept of disparate impact and know how to build a screening policy that protects your property while being fair and compliant.

What Is the Disparate Impact Rule?

The Fair Housing Act (FHA) prohibits discrimination based on race, color, national origin, religion, sex, familial status, and disability. This includes obvious, intentional discrimination, like refusing to rent to someone because of their race.

But the FHA also prohibits practices that have an unintentional discriminatory effect. This is the core of the disparate impact rule. A policy can be discriminatory if it disproportionately harms members of a protected class, even if the policy seems neutral on its face.

Think of it this way. A landlord's policy of denying all applicants with any criminal record whatsoever might be applied to everyone equally. However, due to well-documented inequities in the U.S. justice system, certain racial and ethnic groups are arrested and convicted at higher rates. Therefore, a blanket ban on applicants with a criminal history can have a disparate impact on those groups, making it a potential violation of the Fair Housing Act.

The Department of Housing and Urban Development (HUD) has issued guidance clarifying that overly broad criminal history policies can be a form of illegal discrimination. The key is that your policy must be directly related to a legitimate, non-discriminatory business need, and there should not be a less discriminatory alternative available.

Why a Blanket Ban Is a Major Risk

Aside from the legal risks of a disparate impact claim, a blanket policy to deny anyone with a criminal past is often bad for business. Such a rigid rule fails to consider the specifics of a person's history and their current qualifications as a tenant.

You Lose Potentially Great Tenants

A blanket ban treats a 20-year-old conviction for a minor, non-violent offense the same as a recent conviction for a violent felony. It fails to account for rehabilitation, context, or time. An applicant who made a mistake years ago but has since maintained a stable job and a positive rental history could be an excellent tenant, but a blanket ban would prevent you from ever knowing.

You Open Yourself to Lawsuits

Fair housing advocacy groups and government agencies actively investigate landlords with overly restrictive screening policies. A disparate impact claim can be costly and time-consuming to defend, even if you believe your policy was fair. The legal standard does not require proof of discriminatory intent, only proof of a discriminatory effect. Creating a more nuanced policy is a powerful way to mitigate this significant risk.

How to Create a Defensible Criminal Screening Policy

The best way to protect yourself is to move away from a simple “yes or no” approach. Instead, develop a written policy that evaluates criminal history on a case-by-case basis. Your goal is to determine if an applicant's history indicates a demonstrable risk to the safety of residents or property.

1. Write Your Policy Down

An unwritten policy is difficult to defend. Your screening criteria should be written down and saved. This demonstrates that you have a standardized process and helps you apply it consistently to every single applicant.

2. Distinguish Between Arrests and Convictions

Your policy should not treat arrests as proof of wrongdoing. An arrest is not a conviction. Many arrests never lead to charges or result in a “not guilty” verdict. Basing a rental decision solely on an arrest record is highly likely to be viewed as discriminatory. Focus your review on convictions.

3. Consider the Nature and Severity of the Crime

Your policy should weigh the type of crime committed. Not all convictions carry the same weight when it comes to housing.

• Relevant Crimes: Focus on convictions for crimes that would endanger other residents or your property. This typically includes violent felonies, arson, destruction of property, and sexual offenses.
• Less Relevant Crimes: A conviction for a past financial issue or a minor, non-violent offense may have little to do with an individual's ability to be a good tenant.

Your written policy can specify which categories of convictions are of concern. For example, you might state that you do not consider misdemeanor convictions that are more than three years old.

4. Factor in When the Conviction Occurred

The more time that has passed since the conviction, the less relevant it becomes. Evidence of rehabilitation is a powerful factor. A conviction from a decade ago, followed by a clean record and steady employment, presents a very different picture than a conviction from last year. Your policy should include a specific “lookback period,” the maximum amount of time you will consider. Be sure to check state and local laws, as some jurisdictions legally limit how many years you can look back.

The Importance of an Individualized Assessment

This is the most critical part of a modern, compliant screening policy. Instead of an automatic denial, your policy should include a process for an individualized assessment for any applicant who is flagged due to their criminal history.

This means you give the applicant an opportunity to provide more information. The applicant can offer context about the conviction or provide evidence of rehabilitation. This might include:

• A letter of explanation from the applicant.
• Letters of recommendation from employers, parole officers, or counselors.
• Proof of completion of a rehabilitation program or anger management class.
• A stable employment and rental history since the conviction.

By considering this additional information, you are no longer using a blanket ban. You are making a thoughtful, case-by-case decision based on the totality of the circumstances. Documenting this assessment is crucial. Using a property management platform can help you keep organized, time-stamped records of your screening process and communications for every applicant.

Applying Your Policy Consistently

A well-written policy is only effective if you apply it to every applicant without exception. Inconsistency is a major red flag for housing discrimination.

Do not run a background check on one applicant but waive it for another who “seems nice.” If your policy is to run a criminal background check as part of your screening package, you must do so for every adult applicant who makes it to that stage.

Keep meticulous records of your decisions. For any applicant you deny, your records should clearly show how they failed to meet your pre-established, written rental criteria. This documentation is your best evidence that you are operating a fair and compliant business.

Your Next Step

A strong screening policy is your first line of defense. Your next step is to draft or review your tenant screening criteria, paying close attention to how you handle criminal background checks. Once you have a written policy that includes individualized assessments, have it reviewed by a local landlord-tenant attorney to confirm it aligns with all current regulations in your area.
