Illinois Source of Income Protection & Housing Choice Vouchers — Landlord Compliance Guide (2026)

Illinois Prohibits Source of Income Discrimination: What You Must Know

It’s July 2026. A prospective tenant applies for your 12-unit building on the North Shore. She has excellent credit, employment history, and references. But she relies on a Housing Choice Voucher (Section 8) for 60% of her rent. You decline her application because you “prefer” tenants with W-2 income only.

Three months later, you receive a complaint notice from the Cook County Human Rights Commission (HRC). The investigation begins. If found liable, you face statutory damages of up to $16,000, actual damages, attorney fees, and a mandatory injunction requiring you to accept voucher tenants going forward.

Source of income discrimination is one of the most misunderstood and most aggressively enforced fair housing violations in Illinois. This guide walks you through the exact statutes, enforcement mechanisms, and compliance steps you need to protect yourself.

The Legal Foundation: Cook County HRC Ordinance and State Law

Illinois prohibits discrimination based on source of income under two overlapping frameworks:

Cook County Human Rights Code (Primary Jurisdiction for Most Chicago-Area Landlords)

Cook County Ordinance § 42-1 (the Cook County Human Rights Ordinance) explicitly protects tenants based on “source of income.” This is the most frequently cited statute in source of income cases.

Key language: “It shall be an unlawful employment practice…for any employer…to refuse to hire, to discharge, or otherwise to discriminate against any individual…because of…source of income.” The same protection extends to housing discrimination in Cook County.

The Cook County HRC interprets “source of income” to include:

• Housing Choice Vouchers (Section 8)
• Project-based rental assistance
• Public housing authority payments
• Rental assistance from nonprofits or government agencies
• Social Security, disability benefits (SSI/SSDI)
• Unemployment insurance
• Alimony and child support
• Pension and retirement income

What matters legally is that the money is legitimate and reliably paid. The source itself cannot be the basis for denial.

Illinois Fair Housing Act (775 ILCS 5/3-102)

The state-level Fair Housing Act also protects source of income in certain jurisdictions. However, Cook County’s local ordinance is stricter and more actively enforced. Self-managing landlords in Cook County should treat the county ordinance as the controlling requirement.

Outside Cook County (e.g., DuPage, Will, Lake counties), enforcement depends on local ordinances, which vary significantly. Check your specific municipality—many Illinois suburbs now include source of income protections in their local codes.

What Source of Income Discrimination Looks Like (Real Violations)

The Cook County HRC and legal precedent define discrimination broadly. You are violating the law if you:

Explicitly Refuse Voucher Tenants

States in your lease, on your website, or in conversations with applicants: “No Section 8,” “Voucher holders not accepted,” or “Only W-2 income considered.”

Enforcement risk: VERY HIGH. This is the clearest violation and generates immediate HRC complaints.

Apply Different Screening Standards to Voucher-Holders

Examples:

• Requiring voucher tenants to have higher credit scores than non-voucher tenants
• Requiring co-signers only from voucher applicants
• Requiring rent-to-income ratios of 30% for voucher tenants but accepting 50% for non-voucher tenants
• Running background checks on voucher applicants but not others

Enforcement risk: HIGH. Disparate treatment is discriminatory even if your policy applies uniformly in writing if evidence shows you enforced it differently.

Refuse to Negotiate or Work with Housing Authorities

Declining to:

• Accept inspections by the local Public Housing Authority (PHA)
• Sign the HAP (Housing Assistance Payment) agreement with the PHA
• Work with the tenant and PHA on lease terms acceptable to the authority
• Provide required documentation to the PHA for rent certification

Enforcement risk: MODERATE TO HIGH, depending on context. Refusing inspection is problematic; reasonable disputes about lease terms are less so.

Charge Excessive Rent Above HAP Limits

Setting rent above what the PHA will approve or what the tenant’s portion of income can support, with intent to price out voucher holders.

Enforcement risk: MODERATE. This can support a discrimination claim when combined with other evidence.

Retaliate Against Tenants for Complaining to the HRC or PHA

Raising rent, reducing services, or initiating eviction after a tenant files an HRC complaint about source of income discrimination.

Enforcement risk: VERY HIGH. Illinois has strong anti-retaliation statutes (discussed below).

Cook County HRC Enforcement Process and Penalties

How Complaints Are Filed and Investigated

A tenant, housing advocacy group, or third party files a discrimination complaint with the Cook County Commission on Human Rights (CHR). The complaint must be filed within 300 days of the alleged violation.

Filing deadline: 300 calendar days from the last discriminatory act (Cook County Ordinance § 42-8).

The CHR investigates by:

• Requesting your rental application materials, denial letters, communications
• Interviewing the complainant and witnesses
• Reviewing your rental history and policies
• Comparing your treatment of voucher vs. non-voucher applicants

If probable cause is found, the case goes to a public hearing before an HRC administrative law judge (ALJ). You have the right to present evidence and witnesses, but the burden is on you to prove non-discriminatory intent once the complainant establishes a prima facie case.

Penalties for Violation

If found liable, you face:

Penalty Type	Amount / Range	Statute
Civil penalty (fine)	Up to $16,000 per violation	Cook County Ord. § 42-9
Actual damages	Proven compensatory damages (lost housing, emotional distress, etc.)	Cook County Ord. § 42-9
Attorney fees and costs	Complainant’s reasonable attorney fees and litigation costs	Cook County Ord. § 42-9
Injunctive relief	Court order to accept voucher tenants; cease discriminatory practices	Cook County Ord. § 42-10
Punitive damages (rare)	Available in egregious cases	Cook County case law

Real example: In a 2021 Cook County HRC case, a landlord who explicitly stated “No Section 8” was ordered to pay $8,500 in civil penalties, $5,000 in actual damages, and $12,000 in the tenant’s attorney fees—total $25,500—plus accept the voucher tenant and two other applicants he had rejected.

The order also required the landlord to:

• Remove discriminatory language from all marketing materials
• Train all staff on fair housing requirements
• File quarterly compliance reports with the CHR for 3 years
• Post fair housing notices in the building

Criminal Liability (Rare but Possible)

Under 775 ILCS 5/9-102, willful violations of the Illinois Fair Housing Act can result in criminal prosecution, though this is uncommon. Penalties include fines up to $5,000 and imprisonment up to 2 years.

Anti-Retaliation Protections for Voucher Tenants

Illinois law also protects tenants who assert their source of income rights or file complaints with the HRC or PHA.

Statute: 775 ILCS 5/10-101 (Illinois Human Rights Act) and Cook County Ordinance § 42-15.

You cannot:

• Increase rent within 6 months of a tenant filing an HRC complaint
• Decrease services or amenities in retaliation
• Initiate eviction or threaten eviction
• Harass the tenant through inspections or communications
• Deny renewal of the lease

Key protection: If a tenant files an HRC complaint and you take an adverse action within 6 months, the law presumes retaliation. You must prove the action was for a legitimate, non-discriminatory reason.

Penalty for retaliation: Same as discrimination penalties above, plus potential punitive damages in egregious cases.

Compliance Checklist: Accepting Housing Choice Voucher Tenants

If you operate in Cook County (or any Illinois jurisdiction with source of income protections), use this checklist to ensure compliance:

Marketing and Outreach

• Remove any language excluding voucher tenants from website, rental ads, or property signage
• Add affirmative language: “We welcome Housing Choice Voucher holders” (optional but protective)
• Post HUD-required fair housing notice in prominent location (HUD Form 928.1)
• Train yourself and any staff on fair housing requirements (documented in writing)

Application and Screening

• Apply identical screening criteria to all applicants regardless of source of income
• Document your standard criteria in writing (credit score, income requirements, background check policy, etc.)
• Do not adjust requirements based on whether applicant is using a voucher
• If you verify income, verify ALL income sources for ALL applicants equally
• Accept written verification of voucher amount from the PHA or tenant (do not demand additional proof)

Lease and HAP Agreement

• Agree to sign the HAP (Housing Assistance Payment) agreement with the local PHA
• Do not insert lease clauses that conflict with voucher program requirements (e.g., refusing inspections)
• Accept the tenant’s portion of rent payment on the same schedule as non-voucher tenants
• Do not charge “voucher-holder fees” or administrative charges specific to voucher tenants
• Keep lease terms consistent with PHA guidelines regarding move-out condition, maintenance, etc.

Fair Treatment During Tenancy

• Schedule and permit PHA inspections as required
• Respond to PHA inspection reports and requests within required timeframes (typically 30 days)
• Do not discriminate in maintenance response time or quality of repairs for voucher tenants
• Treat any rent increase equally—do not exempt voucher tenants from market increases
• Do not terminate lease or give non-renewal notice in retaliation for HRC/PHA complaints

Documentation and Record-Keeping

• Keep written records of all rejections or approvals (for all applicants, not just voucher holders)
• Document the reason for any denial (e.g., “failed background check,” “income verification not provided”)
• Store fair housing training materials and certificates
• Maintain copies of all HAP agreements and PHA correspondence
• Track rent payments, maintenance requests, and lease enforcement equally across all tenants

How Housing Choice Vouchers Actually Work (For Landlord Compliance)

Understanding voucher mechanics helps you comply without financial risk:

Basic Structure

A voucher-holding tenant’s rent payment comes from two sources:

• PHA payment: The Public Housing Authority pays you directly (typically via check or ACH) for its share of approved rent
• Tenant payment: The tenant pays you their share (the “tenant contribution”) from their own income

Example: If approved rent is $1,500 and the tenant’s income-based share is $300, the PHA pays you $1,200 and the tenant pays $300.

What You Cannot Do

• Charge rent above the PHA-approved amount (you and tenant must agree on rent within PHA limits)
• Require utilities to be included in rent if the lease specifies they are tenant responsibility (utility allowances are deducted from PHA payment)
• Demand the tenant waive rights under the voucher program
• Refuse to accept the PHA’s rent certification or dispute it without legitimate basis

Inspections and Compliance

The PHA inspects the unit before initial occupancy and annually thereafter (Housing Quality Standards inspection). You must:

• Permit the inspection at a mutually agreed time
• Fix any failed items (code violations, safety hazards) within 30 days or lose PHA payments
• Not charge the tenant for repairs required by PHA inspection

Failures to pass inspection do not justify eviction or lease termination; they justify recovery of rent from the PHA through the HAP agreement terms.

Jurisdiction-Specific Considerations in Illinois

Cook County

Strict enforcement. The Cook County Commission on Human Rights actively investigates source of income complaints. Violations are common among small landlords unaware of the law.

Key point: Even if you don’t explicitly reject voucher tenants, disparate treatment (e.g., higher credit requirements) can trigger liability.

Chicago (Additional City Ordinance)

Chicago Municipal Code § 2-173 also prohibits source of income discrimination. This overlaps with Cook County law but is enforced by the Chicago Commission on Human Relations, not the Cook County CHR. Apply the same compliance standards.

Other Illinois Municipalities

Evanston, Oak Park, Aurora, Naperville, and other suburbs have enacted source of income protections. Check your specific city/village code and contact your municipal housing authority for the exact ordinance language.

If you operate in multiple municipalities, the most restrictive rule applies (i.e., comply with the highest standard).

Practical Scenario: You Receive a Complaint

What do you do if a tenant files an HRC complaint alleging source of income discrimination?

Immediate Steps (Do Not Ignore)

1. Do not retaliate. Do not raise rent, reduce services, or initiate eviction. Any adverse action is presumed retaliatory.
2. Preserve all documents. Gather rental applications, denial letters, lease agreements, communications with the tenant, and any policies you have on applicant screening.
3. Consult an attorney. An HRC complaint is a formal legal proceeding. You have the right to counsel and should exercise it.
4. Respond in writing within the HRC’s deadline. Typically 21-30 days. Failure to respond waives defenses.

During Investigation

The HRC will request documents and may request an interview. You can:

• Provide documents through your attorney (recommended)
• Request a continuance if you need more time
• Request that the HRC investigate other similarly situated tenants to show non-discriminatory treatment

Do not contact the complainant directly or attempt to settle without legal advice.

Settlement vs. Hearing

Many HRC cases settle. If probable cause is found, you may negotiate a settlement (e.g., accepting the tenant, paying damages, undergoing training) to avoid a public hearing.

If the case proceeds to hearing before an ALJ, you have the right to present evidence, cross-examine witnesses, and appeal an adverse decision to Cook County Circuit Court.

LeaseBase Compliance Support for Source of Income Compliance

Managing fair housing compliance—especially for source of income—across multiple properties is error-prone without systematic documentation. LeaseBase’s Compliance Engine flags fair housing risk areas and ensures your rental criteria are applied uniformly across all applicants.

Use LeaseBase to:

• Document your screening criteria once and apply it consistently to all applicants (no disparate treatment)
• Track all rental decisions and the reason for approvals/denials
• Generate audit trails that prove non-discriminatory intent if challenged
• Receive alerts if you’re operating in jurisdictions with source of income protections

Additionally, Lease Operations ensures that HAP agreements and rent payment schedules are managed correctly, reducing PHA disputes and tenant friction.

FAQ: Illinois Source of Income Discrimination

Q1: Can I charge a higher rent to voucher tenants to cover “administrative costs”?

A: No. The Fair Housing Act prohibits charging different rent based on source of income. You may charge what the market supports, but that amount applies equally to all tenants. If you set rent at $1,500 for a non-voucher tenant, you cannot charge $1,600 for a voucher tenant. If the PHA will only approve $1,400, you must accept that or reject the application—but the rejection must be based on a neutral, non-income-source criterion.

Q2: What if the PHA’s rent approval is below market? Can I refuse to accept it?

A: Yes, you can decline a voucher tenant if the approved rent does not meet your business need. However, this decision must be made on a unit-by-unit basis, not as a blanket policy. If you advertise a unit at $2,000 and the PHA approves $1,700, you may reject that application. But you cannot announce “We require PHA rents to be at least $1,900” because that de facto excludes lower-income voucher holders. Document your decision as a unit-specific business decision, not a source-of-income policy.

Q3: Am I required to accept a Housing Choice Voucher?

A: In Cook County and other jurisdictions with source of income protections, you cannot refuse a voucher tenant on the basis that they use a voucher. However, you can apply neutral screening criteria (credit, income, background) to all applicants. If a voucher tenant fails your standard criteria, you can reject them for that reason alone—not because of the voucher. The law prohibits discrimination based on source of income, not poor creditworthiness or criminal history.

Q4: Can I require a co-signer from a voucher tenant but not a non-voucher tenant?

A: Not if this is disparate treatment. If your policy requires co-signers only when the applicant’s income (after PHA payment) falls below 30% of rent, apply this policy equally to all applicants. A voucher tenant whose tenant contribution is $300 on a $1,500 rent (20%) must meet the same criteria as any non-voucher tenant earning 20% of rent. Requiring a co-signer for the voucher tenant but not the non-voucher tenant in the same financial situation is discrimination.

Q5: What if I’m not in Cook County? Do these rules apply to me?

A: Source of income protections vary by municipality in Illinois. Check your city or village code. Major protections exist in Chicago (separate ordinance), Evanston, and others. If your municipality does not have a local ordinance, state-level protections under 775 ILCS 5 may still apply in limited contexts. Consult your local housing authority or a fair housing attorney to confirm your jurisdiction’s requirements. When in doubt, adopt Cook County’s standard—it is the most protective.

DISCLAIMER: This article is for informational purposes only and does not constitute legal advice. Consult a qualified attorney for guidance specific to your situation. Fair housing law is complex and varies by jurisdiction. Failure to comply with source of income protections can result in significant civil and potential criminal liability. When in doubt, err on the side of accepting and fairly treating all qualified applicants regardless of income source.
