No statewide cap, state law prohibits local rent control
Understanding Illinois rent control is crucial for any landlord, particularly those managing 1-20 units. This guide provides an overview of the state’s distinct approach to rent regulation and the practical implications for your operations. Illinois does not have statewide rent control. This is a critical distinction.
The absence of statewide rent control means landlords in most of Illinois retain significant flexibility in setting and increasing rent. You won't encounter caps on rent increases or specific limits on how much you can charge, as seen in some other states. However, this freedom comes with specific procedural requirements, especially concerning eviction. Ignoring these procedures creates significant legal risk.
The primary legal framework governing landlord-tenant disputes, including eviction, is the Forcible Entry and Detainer Act (735 ILCS 5/9). This statute outlines the specific steps landlords must follow to regain possession of a property. Deviating from these steps can invalidate an eviction attempt, costing you time and money.
While Illinois lacks statewide rent control, individual municipalities can enact their own rent control ordinances. This is a critical point. Chicago, for example, has its own Residential Landlord and Tenant Ordinance (RLTO) which, while not rent control in the traditional sense, imposes strict rules on security deposits, notice periods, and landlord responsibilities. Evanston also has its own specific ordinances. You must be aware of any local ordinances in the specific municipality where your rental property is located.
For most landlords outside of major metropolitan areas with specific ordinances, the Illinois Attorney General's Office and local circuit courts are the primary enforcers of landlord-tenant law. The Attorney General's office provides guidance and handles consumer complaints. Local courts adjudicate eviction cases and other disputes.
Your primary focus in Illinois, absent statewide rent control, is adherence to proper notice procedures and fair housing laws. Don't skip notice periods; do follow them precisely.
One concrete example of a common landlord mistake involves improper notice. A landlord might verbally tell a tenant, "You need to move out by the end of the month." This is insufficient. For a month-to-month tenancy, the landlord must provide a formal, written 30-day notice to quit. If the landlord attempts to evict based on a verbal notice, the court will almost certainly rule in favor of the tenant, forcing the landlord to restart the eviction process correctly. This means lost rent and additional legal fees.
As of recent legislative sessions, Illinois has seen ongoing discussions surrounding tenant protections, though significant statewide rent control measures have not passed. There has been legislative activity around issues such as source of income discrimination and enhanced notice periods for lease non-renewals. For instance, proposals have surfaced in the Illinois General Assembly to extend the notice period for non-renewal of a lease for longer-term tenants from 30 days to 60 or even 90 days, though these have not yet become law. Stay informed about legislative updates that could impact notice requirements or add new tenant protections, particularly at the local level. These changes, even if not full rent control, can significantly alter your operational procedures and timelines.

Illinois state law expressly prohibits Illinois cities, counties, and other political subdivisions from enacting rent-control or rent-stabilization ordinances, codified at 735 ILCS 5/9 (Forcible Entry and Detainer). Any Illinois city-level ordinance purporting to limit residential rent on private market-rate units is unenforceable as a matter of Illinois law. The preemption has been consistently upheld by Illinois appellate courts and has been in force for decades in most cases.
A Illinois landlord may raise the rent on a residential unit by any amount at the end of a lease term or on a month-to-month tenancy, subject only to three limits: (1) proper written notice of the increase, typically 30 days for a month-to-month tenancy, or whatever the lease provides for renewal of a fixed-term lease; (2) compliance with federal and Illinois fair-housing law, a rent increase targeted at a protected class (race, color, religion, sex, national origin, familial status, disability, and additional Illinois state classes) or at voucher-holders in jurisdictions that protect source of income is actionable; and (3) compliance with Illinois anti-retaliation law, a rent increase issued within 6 months after a tenant code complaint, habitability report, fair-housing contact, or tenant-organizing activity is presumed retaliatory and the landlord must rebut with a documented non-retaliatory business reason.
Preemption of rent control does not bar Illinois localities from regulating other aspects of the residential landlord-tenant relationship. Illinois cities remain free to enact local just-cause termination ordinances, source-of-income discrimination rules, security-deposit interest requirements, stricter habitability and code-enforcement standards, mandatory tenant relocation assistance, eviction-filing moratoria, landlord-registration requirements, and rent-registry programs. Before treating a Illinois rental as wholly unregulated, always check the current municipal code in the Illinois city or county where the property is located for non-rent ordinances that still apply.
| City | Ordinance | Annual Cap | Just Cause | SFR |
|---|---|---|---|---|
| Chicago | RLTO + state-level just-cause rules | None (no statewide cap, state preemption repealed 2023) | No | No |
No. The Rent Control Preemption Act, 50 ILCS 825/5, has prohibited Illinois municipalities from enacting rent control since 1997. The preemption is comprehensive: "no unit of local government may enact, maintain, or enforce an ordinance or resolution that would have the effect of controlling the amount of rent." Chicago, Cook County, Evanston, Oak Park, and other Illinois jurisdictions cannot enact local rent control under current law.
Yes, repeatedly since 2019. Lift the Ban Coalition has pushed for repeal. HB 255 of 2019 would have repealed the preemption; it passed two Illinois House committees but did not reach the floor. Subsequent legislative sessions (2021, 2023, 2025) have seen reintroductions and hearings without final passage. Cook County, Chicago, and Evanston have passed non-binding resolutions calling for repeal. The effort is dormant but the political coalition remains organized and could move again.
A comprehensive non-rent-control framework. Chicago RLTO (Municipal Code Ch. 5-12): security deposit cap at 1.5 months rent with annual interest, habitability framework, notice content requirements. Chicago Just Cause Eviction Ordinance (effective 2021): just-cause required for non-renewal of tenancies of 6+ months. Statewide source-of-income protection (Illinois Human Rights Act, since January 1, 2023). Eviction record sealing (735 ILCS 5/9-121). The framework produces many of the practical effects of rent control through other mechanisms.
The Cook County Residential Tenant Landlord Ordinance, effective 2021 and expanded 2024. It covers most rentals in suburban Cook County (Chicago has its own RLTO). The RTLO provides a habitability framework, deposit rules, retaliation prohibition, source-of-income protection (duplicating the state-level protection), and just-cause eviction for tenancies of 6+ months. The combined Chicago RLTO + Cook County RTLO + Illinois Human Rights Act stack is one of the more comprehensive non-rent-control tenant-protection frameworks in the country.
Local rent control would be permitted in Illinois municipalities. Likely first-mover cities based on the past decade of political activity: Chicago, Evanston, Oak Park, Urbana, Champaign. The Chicago framework would likely add a rent-stabilization layer to the existing RLTO + Just Cause stack. The form of any such ordinance would be subject to political negotiation; reasonable models include the New Jersey municipal-rent-control model (4-6 percent annual cap), the Oregon SB 608 statewide model (7 percent plus CPI), or a CPI-only model similar to Takoma Park's. None of this is operative as of 2026; the preemption remains in force.
