Oak Park is an inner-ring suburb in Cook County located immediately west of Chicago, known for its historic architecture and progressive community character. Oak Park renters benefit from two layers of protection: Illinois state landlord-tenant law and the Oak Park Residential Landlord and Tenant Ordinance (RLTO), which provides enhanced protections on security deposits, habitability standards, and tenant remedies beyond what state law alone requires.
Despite these local protections, Oak Park cannot enact rent control — Illinois state law (765 ILCS 720) prohibits local rent stabilization ordinances statewide. Landlords in Oak Park may raise rent by any amount with proper notice. However, the Oak Park RLTO's protections in other areas — particularly around security deposits and habitability — are meaningfully stronger than the statewide baseline.

Oak Park has no rent control, and Illinois state law (765 ILCS 720) prohibits all municipalities from enacting rent control or rent stabilization ordinances. This statewide preemption applies to Oak Park just as it applies to every other Illinois municipality. The Oak Park Village Board has no legal authority to cap rent increases or impose rent registration requirements.
An Oak Park landlord may raise rent by any dollar amount. The only constraint is proper written notice — at least 30 days' written notice is required before a month-to-month tenancy can be terminated or a rent increase imposed on month-to-month tenants. Fixed-term lease tenants cannot have rent raised mid-lease unless the lease expressly permits it. Tenants who cannot afford a rent increase have no legal mechanism to challenge the amount under Illinois law.
Oak Park renters are protected by both Illinois state law and the Oak Park RLTO. Key state-law protections include:
The Oak Park Residential Landlord and Tenant Ordinance (RLTO) provides protections beyond Illinois state law for Oak Park renters. Key provisions include:
Enhanced Security Deposit Protections: The Oak Park RLTO requires landlords to return security deposits — or provide a written itemized statement of deductions — within 30 days of move-out. Landlords who fail to comply may be liable for twice the amount wrongfully withheld plus reasonable attorney's fees. Deposits must generally be held in a federally insured account, and interest requirements may apply depending on building size.
Habitability Remedies: The Oak Park RLTO codifies habitability obligations and provides tenants with explicit remedies when landlords fail to maintain safe and habitable conditions. Remedies may include the right to place rent in escrow, repair-and-deduct, or terminate the lease if conditions are severe and the landlord fails to act after written notice.
Required Disclosures: Landlords covered by the Oak Park RLTO may be required to provide tenants with a copy of the ordinance summary at the start of the tenancy. Failure to make required disclosures can affect the landlord's ability to enforce certain lease terms.
Scope: The Oak Park RLTO covers most residential rental units in the village. Exemptions may apply to owner-occupied buildings with a limited number of units — tenants should confirm coverage with Prairie State Legal Services or a local attorney.
Security deposit rules in Oak Park are governed by the Oak Park Residential Landlord and Tenant Ordinance (RLTO) and the Illinois Security Deposit Return Act (765 ILCS 710). The Oak Park RLTO provides protections that are stronger than state law alone.
Return Deadline: Your landlord must return your security deposit — or provide a written itemized statement of deductions — within 30 days after you vacate the unit.
Interest on Deposits: The Oak Park RLTO may require landlords to hold deposits in a federally insured interest-bearing account and pay interest. Confirm the current interest requirement with Prairie State Legal Services if this applies to your tenancy.
Penalty for Wrongful Withholding: Under the Oak Park RLTO, if your landlord fails to return the deposit or provide the required itemized statement within 30 days, you may be entitled to twice the amount wrongfully withheld plus reasonable attorney's fees. Document the unit's condition thoroughly with dated photos at move-in and move-out, and provide your forwarding address in writing when you leave.
Evictions in Oak Park must follow Illinois's formal court process — self-help eviction is illegal. For nonpayment of rent, the landlord must serve a 5-day written notice to pay or vacate. For lease violations, a 10-day notice to cure or vacate applies. To terminate a month-to-month tenancy, at least 30 days' written notice is required.
If the tenant does not comply, the landlord may file an eviction action in Cook County Circuit Court. Tenants have the right to appear, contest the eviction, and raise defenses including habitability violations, improper notice, retaliation, and non-compliance with Oak Park RLTO disclosure requirements. Contact Prairie State Legal Services or Illinois Legal Aid Online well before your court date.
Only the Cook County Sheriff may physically remove a tenant — not the landlord. A landlord who changes locks, shuts off utilities, or removes a tenant's belongings without a court order commits illegal self-help eviction and may face civil liability under the RLTO and state law.
No. Despite having a strong local RLTO, Oak Park cannot enact rent control because Illinois state law (765 ILCS 720) prohibits all municipalities from enacting rent control or rent stabilization ordinances. This statewide preemption applies to Oak Park just as it applies to every other Illinois community.
There is no legal cap on rent increases in Oak Park. Illinois's statewide prohibition (765 ILCS 720) bars any local rent stabilization. For month-to-month tenants, your landlord must give at least 30 days' written notice before a rent increase takes effect. Fixed-term lease tenants are protected from mid-lease increases unless the lease expressly allows them.
Under the Oak Park RLTO and the Illinois Security Deposit Return Act (765 ILCS 710), your landlord must return your deposit or provide a written itemized statement of deductions within 30 days of move-out. Wrongful withholding may entitle you to twice the withheld amount plus attorney's fees under the RLTO. Provide your forwarding address in writing when you move out.
5 days for nonpayment of rent, 10 days for lease violations, or at least 30 days to terminate a month-to-month tenancy under Illinois law. After proper notice, the landlord must file in Cook County Circuit Court. The Oak Park RLTO may provide additional defenses — contact Prairie State Legal Services for guidance specific to your situation.
No. Self-help eviction is illegal in Illinois and may also violate the Oak Park RLTO. A landlord who changes locks, removes doors, or shuts off utilities to force you out without a court order may face civil liability. Contact Prairie State Legal Services or Illinois Legal Aid Online immediately if this happens.
The Oak Park RLTO provides explicit habitability remedies including the right to place rent in escrow, use repair-and-deduct, or terminate the lease if conditions are severe. Send a written repair request first and keep a copy. Do not withhold rent or use any remedy without first consulting Prairie State Legal Services or Illinois Legal Aid Online.
