Chicago renters often ask whether the city can cap rent increases the way New York or San Francisco can. Under current Illinois law, it cannot. But Chicago’s Residential Landlord and Tenant Ordinance does control how much notice a landlord must give before raising rent, and it prohibits increases used as retaliation. Those rules give Chicago renters real time to plan, especially long term tenants.
With about 54 percent of occupied homes rented, a median gross rent of $1,440 a month, and a median household income of $77,902 over 2020 to 2024 (U.S. Census Bureau QuickFacts, Chicago), the rules on rent increases affect a majority of Chicago households.

Quick answers
- Rent cap? No; Illinois preempts local rent control (50 ILCS 825).
- Notice of increase: 30, 60, or 120 days depending on how long you have lived there, in RLTO covered units (RLTO Summary).
- Retaliation: raising rent to punish a good faith complaint is prohibited.
Why Chicago cannot cap rent
Illinois’ Rent Control Preemption Act provides that a unit of local government shall not enact, maintain, or enforce an ordinance or resolution that would have the effect of controlling the amount of rent charged for private residential or commercial property. A separate section applies that limit to home rule units, which include Chicago. The Act’s only exception concerns property in which the local government holds an interest (50 ILCS 825, Rent Control Preemption Act). Unless the Illinois General Assembly changes that law, Chicago cannot adopt rent control.
The Fair Notice rules
The RLTO’s Fair Notice provisions require landlords to give advance notice to terminate a month to month tenancy, to decline to renew a lease, or to raise rent, with the length of notice depending on how long you have lived in the unit (City of Chicago, RLTO Summary):
| How long you have lived in the unit | Minimum notice |
|---|---|
| Less than six months | 30 days |
| Six months to three years | 60 days |
| More than three years | 120 days |
For a tenant who has lived in an apartment for four years, that means a landlord planning an increase at renewal must give roughly four months’ notice. Mark your lease end date and watch for the notice; if it arrives late, ask a legal aid organization how the Fair Notice rules apply to your situation.
Is your unit covered?
The RLTO does not cover units in owner occupied buildings with six or fewer units, owner occupied co ops and condos, and certain other housing (City of Chicago, RLTO Summary). Chicago has many two flats and three flats with resident owners, so check this first.
Retaliation
The RLTO prohibits landlords from retaliating against tenants who exercise their rights or complain in good faith. Prohibited retaliation includes raising rent, decreasing services, terminating or threatening to terminate a tenancy, bringing or threatening an eviction, or refusing to renew (City of Chicago, RLTO Summary). If an increase follows a complaint to the city about building conditions, keep records of both.
Discrimination
The federal Fair Housing Act prohibits discrimination in the terms or conditions of renting because of race, color, religion, sex, familial status, national origin, or disability (42 U.S.C. § 3604). HUD accepts fair housing complaints (HUD, File a Complaint).
When the rent can change
- Fixed term lease: the rent generally stays as written until the term ends, unless the lease allows a change.
- Renewal: the landlord may offer new terms, subject to the Fair Notice periods above if the unit is covered.
- Month to month: changes require the Fair Notice periods above for covered units.
How Chicago rents compare with incomes
At the citywide median household income of $77,902, 30 percent of gross income is about $1,948 a month, above the median gross rent of $1,440 (U.S. Census Bureau QuickFacts). But that income figure covers all households, homeowners as well as renters, so it may not reflect a typical renter’s budget. Apply the same calculation to your own income and the proposed rent before deciding how to respond.
Negotiating a renewal
Knowing the rules gives you time. Using that time well is what turns a notice into a negotiation.
- Use the notice period. Sixty or 120 days gives you time to compare apartments before you must decide.
- Collect comparisons. Save dated listings for similar units in your neighborhood.
- Make a specific counteroffer, such as a smaller increase for a longer lease.
- Ask about winter timing. Some landlords may value a renewal that avoids a vacancy during slower leasing months.
- Get final terms in writing before signing.
A sample response
Hello, thank you for the renewal offer for [address, unit]. I would like to stay. Comparable apartments nearby are listed at [amounts]. I have paid on time for [number] years. Would you consider [specific amount] for a [length] lease? Sincerely, [name].

If you cannot afford the increase
- Ask about a different lease length. Some landlords price longer terms lower to avoid turnover.
- Ask about a smaller unit in the same building or from the same owner.
- Look at the total monthly cost, including parking, utilities, and fees, not only base rent.
- Contact 211 to ask about rental assistance programs in Chicago (211.org).
- Decide before your deadline, so you can give proper notice if you choose to move.
At Chicago’s median gross rent of $1,440, a 5 percent increase adds about $72 a month, or about $864 a year. Comparing that annual figure with the cost of moving, including a new deposit and moving expenses, often clarifies the decision.

Chicago at a glance
Chicago has about 1.16 million households, averaging 2.29 people each, and a median household income of $77,902 over 2020 to 2024 (U.S. Census Bureau QuickFacts, Chicago). The RLTO’s owner occupied exclusion matters here: in a building of six or fewer units where the owner lives, the RLTO deposit rules may not apply (City of Chicago, RLTO Summary). Ask your landlord at lease signing whether they live in the building.
Key terms
- Preemption: a state law that prevents local governments from acting in a field; here, Illinois’ Rent Control Preemption Act.
- Fair Notice: the RLTO provisions setting 30, 60, or 120 days’ notice based on how long you have lived in the unit (City of Chicago, RLTO Summary).
- Retaliation: a landlord action, such as raising rent, taken because a tenant exercised a right or complained in good faith.
- Owner occupied exclusion: the RLTO does not cover owner occupied buildings with six or fewer units.
Frequently asked questions
Is there any limit on how much my Chicago rent can go up?
There is no numeric cap; state law preempts local rent control (50 ILCS 825). The limits are procedural: Fair Notice periods and the ban on retaliation (RLTO Summary).
I have lived here five years. How much notice should I get?
For tenants of more than three years, the Fair Notice provisions call for 120 days in covered units (RLTO Summary).
My landlord lives in the building. Do the Fair Notice rules apply?
Owner occupied buildings with six or fewer units are excluded from the RLTO (RLTO Summary). Check with a legal aid organization about Illinois law that may apply.
Can my landlord raise the rent in the middle of my lease?
Generally only if your lease allows it. A fixed term lease sets the rent for its term, and the Fair Notice periods govern increases at renewal or on a month to month tenancy in covered units (RLTO Summary).
Do the Fair Notice rules apply when my landlord simply declines to renew?
Yes. The RLTO summary lists declining to renew among the actions that require the 30, 60, or 120 day notice, depending on how long you have lived in the unit (RLTO Summary).
Can my landlord punish me with a rent increase for joining a tenants’ group?
The RLTO prohibits retaliation against tenants who exercise their rights or complain in good faith, and raising rent is listed among the prohibited forms of retaliation (RLTO Summary). Document the timing of any increase and your organizing activity.
