Tenant Background Check: What Landlords Can and Can't Ask

Screening tenants is essential. But ask the wrong question and you're looking at a Fair Housing complaint. Here's the complete guide to what's legal, what's not, and how to screen effectively without crossing the line.

Every landlord knows that screening tenants is the single most important thing you do. A bad tenant costs thousands in unpaid rent, property damage, legal fees, and turnover. A good screening process prevents that. But here's the problem: not everything you want to know is something you're allowed to ask.

Federal, state, and local fair housing laws create clear boundaries around tenant screening. Violate them — even accidentally, even with good intentions — and you're exposed to discrimination complaints, lawsuits, and fines that dwarf any damage a bad tenant could cause.

This guide covers exactly what you can screen for, what's off-limits, and how to build a screening process that's both thorough and legally compliant.

The Federal Fair Housing Act: The Foundation

The Fair Housing Act (FHA) prohibits discrimination in housing based on seven protected classes:

1. Race
2. Color
3. National origin
4. Religion
5. Sex (includes gender identity and sexual orientation as of 2021)
6. Familial status (families with children under 18, pregnant women)
7. Disability (physical or mental)

You cannot ask questions that relate to these categories, use them as screening criteria, or apply them differently to different applicants. This applies to every landlord in the country, regardless of portfolio size — with very narrow exceptions (owner-occupied buildings with four or fewer units, and single-family homes rented without a broker, though even these exemptions don't protect discriminatory advertising).

Many states and cities add additional protected classes. Common additions include:

• Source of income (Section 8 vouchers, disability payments)
• Marital status
• Age
• Sexual orientation / gender identity (where not already covered federally)
• Immigration status
• Criminal history (some cities have "ban the box" laws for housing)

Check your state and local fair housing laws before finalizing your screening criteria. What's legal in Texas might be illegal in Seattle.

What You CAN Ask and Screen For

1. Credit History

You can pull a credit report with the applicant's written consent. This is standard and expected. You're looking for:

• Overall credit score (most landlords set a minimum, often 600–650)
• Outstanding collections, especially from previous landlords or utility companies
• Bankruptcy filings
• Debt-to-income ratio
• Payment history patterns (consistent late payments are a red flag)

Important: Under the Fair Credit Reporting Act (FCRA), if you deny an applicant based on their credit report, you must provide an "adverse action notice" that tells them which report you used and how to dispute errors. This isn't optional — it's federal law. For alternative approaches, see our guide on screening tenants without a credit check.

2. Income and Employment

You can ask about income and require proof. The standard threshold is 3x monthly rent in gross income. Acceptable verification includes:

• Recent pay stubs (2–3 months)
• Employment verification letter
• Tax returns (for self-employed applicants)
• Bank statements (with sensitive info redacted)

What you can't do: In jurisdictions with source-of-income protections, you cannot reject an applicant solely because their income comes from Section 8, Social Security disability, child support, or other government assistance. If their total income meets your threshold, the source doesn't matter.

3. Rental History

You can — and should — contact previous landlords. Ask specific, factual questions:

• Did the tenant pay rent on time?
• Did they give proper notice before leaving?
• Were there any lease violations?
• Would you rent to them again?
• How did they leave the property's condition?

Pro tip: Contact the landlord before the current one. The current landlord might give a glowing reference just to get rid of a problematic tenant.

4. Eviction History

You can check for prior evictions through court records or a tenant screening service. An eviction filing is a strong signal, though context matters — some evictions were filed but dismissed, and pandemic-era eviction moratoriums created unusual situations.

5. Criminal History (With Major Caveats)

This is where it gets complicated. In most states, you can run a criminal background check. However:

• Arrests without convictions — You generally cannot use arrest records (without conviction) to deny housing. An arrest doesn't prove anything.
• Blanket criminal bans are illegal. HUD has issued guidance that blanket "no criminal history" policies violate the Fair Housing Act because they disproportionately impact minority applicants. You must do an individualized assessment.
• Individualized assessment means: Consider the nature of the crime, how long ago it occurred, and whether it's relevant to tenancy. A 20-year-old marijuana possession charge is very different from a recent violent felony.
• Some cities ban criminal history screening entirely for housing (e.g., Seattle, San Francisco). Check local law.

6. Identity Verification

You can ask for government-issued ID to verify the applicant is who they say they are. You can verify their Social Security number for the credit check. What you cannot do is ask about immigration status or require proof of citizenship — this would constitute national origin discrimination under the FHA.

What You CANNOT Ask

These questions are off-limits. Don't ask them in conversation, on applications, or during showings. Even casual small talk can become evidence in a discrimination claim.

Questions About Family

• "Do you have kids?" / "How many children do you have?"
• "Are you pregnant?" / "Are you planning to have children?"
• "Who will be living with you?" (You can ask how many occupants for occupancy limits — but you can't use this to screen out families)
• "Are you married?" / "Is this for you and your boyfriend?"

You can set reasonable occupancy limits (typically 2 persons per bedroom as a baseline), but you cannot use those limits as a pretext to exclude families with children.

Questions About Disability or Health

• "Do you have a disability?"
• "Why do you need a first-floor unit?" (Even if you're trying to be helpful)
• "Are you in a wheelchair?"
• "Do you take medication?"
• "Do you have a mental illness?"

If a tenant requests a reasonable accommodation (like an assistance animal or a reserved parking spot), you must engage in an interactive process. You can request documentation from a medical professional that confirms the need, but you cannot ask about the specific diagnosis.

Questions About Religion, Race, or National Origin

• "Where are you from?" / "What country are you from originally?"
• "What church do you go to?"
• "What language do you speak at home?"
• "What's your ethnic background?"

These seem obviously illegal, but they come up in casual conversation during showings more often than you'd think. Keep conversations focused on the property and the tenancy.

Questions About Age

• "How old are you?"
• "Are you retired?"
• "Are you a student?"

Exception: housing specifically designated for seniors (55+ communities) can ask about age.

How to Build a Legal, Effective Screening Process

The key principle is consistency. Apply the same criteria, the same process, and the same questions to every applicant. Here's how:

1. Write Down Your Criteria Before You Advertise

Before you list the property, define your minimum requirements in writing:

• Minimum credit score (e.g., 620)
• Minimum income (e.g., 3x monthly rent)
• No evictions in the past X years
• Positive landlord references
• Criminal history policy (individualized assessment)

These criteria must be applied identically to every applicant. Document your decisions.

2. Use a Standard Application

Every applicant fills out the same form with the same questions. Don't add questions for some applicants and not others. Don't ask follow-up questions that relate to protected classes.

3. Use a Screening Service

Services like TransUnion SmartMove, RentPrep, or the screening features in Rentlane standardize the process and create documentation automatically. They pull credit, criminal, and eviction records in a compliant way and give you a consistent framework for evaluation.

4. Document Everything

For every applicant you reject, note the specific reason tied to your written criteria. "Didn't feel right" is not a reason. "Credit score 540, below our 620 minimum" is. Keep these records for at least three years.

5. Send Adverse Action Notices

If you deny an applicant based on a consumer report (credit check, background check), you must send an adverse action notice within a reasonable time. The notice must include the name of the screening company and inform the applicant of their right to dispute the report. Most screening services provide templates for this.

Common Screening Mistakes That Create Legal Risk

The "Gut Feeling" Rejection

You meet the applicant, something feels off, and you deny them without a documented reason. If that applicant is in a protected class and files a complaint, your "gut feeling" defense won't hold up. Always tie rejections to objective, written criteria.

Inconsistent Standards

You require a 650 credit score from one applicant but accept 580 from another because they "seemed more responsible." This pattern of inconsistency is exactly what fair housing investigators look for. Same standards, every time, no exceptions.

Social Media Screening

Looking at an applicant's social media seems harmless, but it exposes you to information about protected classes — religion, family status, disability, national origin — that you now can't "unsee." If you reject the applicant for a legitimate reason, they can argue you were actually influenced by what you saw on Facebook. Best practice: don't look.

Asking "Friendly" Questions During Showings

"So, what do you do for fun? Do you go to church around here? Any kids?" These feel like normal conversation, but they're fishing in protected-class waters. Stick to the property: "Do you have any questions about the lease terms? Would you like to see the laundry room?"

State-Specific Rules to Watch

A few areas where state law significantly affects screening:

• California: Limits security deposits to one month's rent. Restricts criminal background screening to convictions only, and only those directly related to tenancy risk.
• New York: Landlords cannot charge more than $20 for a background check. Cannot consider sealed or expunged records.
• Oregon: Source of income is protected. Cannot deny based on Section 8 vouchers.
• Washington (state): Cannot screen for criminal history until after a conditional offer. First-in-time screening rules in Seattle.
• New Jersey: Cannot ask about criminal history on initial application.
• Illinois (Cook County): "Just Housing" ordinance severely restricts criminal background checks.

These laws change frequently. If you're unsure about your jurisdiction, a one-time consultation with a local landlord-tenant attorney ($200–$500) is money well spent.

The Bottom Line

Tenant screening is your most powerful tool as a landlord, but it comes with rules. The good news: those rules are straightforward once you understand them. Screen for credit, income, rental history, and eviction records. Apply the same criteria to every applicant. Document your decisions. Send adverse action notices when required. And never, ever ask about protected classes — even casually.

The landlords who get in trouble aren't usually the ones being intentionally discriminatory. They're the ones who wing it — different questions for different applicants, "gut feeling" rejections, casual conversations that wander into prohibited territory. Build a system, follow it consistently, and you'll screen effectively while staying on the right side of the law.
