Illinois Tenant Screening Guide - Background Checks, PTSR & Fair Housing 2026

Illinois tenant screening has more legal guardrails than most landlords expect. You can legally screen for credit, income, and rental history — but two major law changes since 2025 added mandatory fee waivers, a new obligation to accept tenant-provided screening reports, and tighter limits on when you can ask about criminal history. A single misstep can trigger a fair housing complaint or an FCRA penalty. Here's exactly what you need to know going into summer 2026.

Two New Laws That Affect Every Illinois Landlord

Portable Tenant Screening Reports Are Now Mandatory

Under Public Act 103-0840^ILGA, effective January 1, 2025, Illinois landlords must accept a valid Portable Tenant Screening Report (PTSR) when an applicant provides one. A PTSR qualifies as valid when:

• It was issued within the last 30 days by a certified consumer reporting agency
• It includes at minimum eviction records, rental history, and income verification
• It is accessible free of charge to you (the landlord)

When an applicant hands you a valid PTSR, you cannot charge an application fee or a separate screening fee. You can ask whether anything material has changed since the report was generated, but you cannot demand a fresh report without cause.

Application Fees Are Now Capped

Starting July 1, 2026, Illinois landlords cannot charge an application fee above $50 unless actual third-party screening costs exceed that amount^{Public Act 103-1031}. Internal administrative costs don't count — only what a background check vendor actually invoices you. If you've been charging $75 or $100 flat, that needs to change now.

Together, these two provisions reduce the financial burden on applicants while still giving you full access to the information you need.

Set Written Screening Criteria Before You Collect Anything

The most important step in any screening process is writing down your criteria before an applicant submits a single document. A written policy does three things:

• Proves consistent treatment if a rejected applicant files a fair housing complaint
• Lets applicants self-screen before spending money on an application
• Creates a defensible record if you're ever audited

Your written criteria should specify your minimum credit score (if any), income requirement, rental history standards (e.g., no evictions in the past 5 years), and how you evaluate criminal records. Post it publicly with your listing and hand it to every applicant before collecting a fee. In Chicago, the RLTO requires you to disclose tenant selection criteria upfront^{City of Chicago} — written criteria satisfy that requirement.

Credit and Income Verification

Income Requirements

Illinois law sets no minimum income-to-rent ratio, but 2.5x to 3x monthly rent is the standard benchmark used by most Chicagoland property managers^Rentvine. On a $1,800/month unit, that means looking for gross monthly income between $4,500 and $5,400. On a $2,500/month apartment in Naperville or Evanston, the target range is $6,250 to $7,500.

Apply the same income ratio to every applicant. Varying the threshold by applicant — even informally — creates fair housing exposure if the variation tracks a protected class.

Acceptable documentation includes:

• Pay stubs from the last 2 months
• Bank statements showing consistent deposits
• Tax returns (last 2 years) for self-employed applicants
• Signed offer letters for newly hired tenants
• Award letters for Social Security, disability, or veteran benefits

Credit Evaluation

No Illinois law requires a minimum credit score, but 600–640 is the typical floor in the Chicago market. One nuance worth knowing: Chicago-area managers often weight a 640 score with 3 years of on-time rent payments more favorably than a 720 score with no rental history^{GC Realty}. If you're evaluating credit, document your methodology so you can demonstrate consistent application.

Criminal Background Checks: Illinois Rules and Cook County Additions

Statewide 3-Year Lookback Limit

Illinois restricts landlords to considering criminal records from the past 3 years^{Landlord Studio}. Arrests — not just convictions — that are older than 3 years cannot be used to deny housing. Blanket policies that reject any applicant with any criminal record are also prohibited; you must weigh the recency, severity, and relevance of an offense to the rental.

Cook County: Conditional Approval Process Required

If your property is in Cook County, additional restrictions apply. You cannot ask about criminal history during prequalification, and you cannot run a criminal background check until an application is otherwise complete — meaning the applicant has met your income, credit, and rental history criteria^{Illinois Legal Aid Online}. Only then can you run the check and factor it into a final decision.

This conditional approach prevents criminal history from functioning as an early filter. If you intend to deny based on a criminal record finding, you must give the applicant a chance to provide context before the final decision is made.

FCRA Consent Is Required Before Any Report

Before running any background check — criminal, credit, or eviction history — the Fair Credit Reporting Act requires written consent from the applicant^AAOA. Build this into your standard application form. Most screening platforms include a consent disclosure automatically, but verify it covers every report type you're ordering.

Protected Classes: What You Cannot Use in Screening

Illinois Human Rights Act Coverage

The Illinois Human Rights Act prohibits discrimination based on more than 14 protected characteristics^NAA, including race, color, religion, national origin, ancestry, sex, pregnancy, disability, age (40+), familial status, military status, unfavorable military discharge, order of protection status, and source of income.

Source of Income: Section 8, Vouchers, and More

Source of income is a protected class statewide, which means you cannot refuse to rent — or apply different screening criteria — because an applicant receives a housing voucher, Section 8 assistance, child support, alimony, Social Security, or any other lawful income source^NAA.

This doesn't mean you can't verify income. It means the origin of that income cannot be the basis for rejection. Your income-to-rent ratio requirement still applies — you just have to count all lawful income sources when calculating whether an applicant meets the threshold. If a voucher covers $1,400 of a $1,800 rent and the applicant earns $2,400 gross per month, their combined verifiable income is $3,800, which clears a 2x ratio.

If you've historically included "no housing vouchers" language in listings or application forms, remove it immediately. That language is a fair housing violation on its face.

How to Issue an Adverse Action Notice

When you deny an application — or offer it on worse terms — based on a consumer report, the FCRA requires a written adverse action notice that includes^AAOA:

• The specific reason(s) for the denial (e.g., "eviction filed within the last 2 years," not "did not meet our criteria")
• The name, address, and phone number of the screening agency
• Notice that the applicant can obtain a free copy of their report within 60 days
• Notice that the applicant can dispute inaccurate information

Vague language doesn't satisfy the FCRA. If the denial was credit-based, say so. If it was a past eviction, state that.
