Chicago RLTO: Tenant Rights, Repairs, and Retaliation

Chicago’s Residential Landlord and Tenant Ordinance (RLTO) gives tenants enforceable rights around security deposits, repairs, heat, landlord entry, lease terms, late fees, lockouts, and retaliation, and it attaches real money damages when a landlord gets any of it wrong. The ordinance lives in Chapter 5-12 of the Municipal Code and covers nearly every residential rental inside city limits. To use its remedies, you generally have to follow its procedures: written notice, waiting periods, and documentation.

Who Is Covered

Almost every residential tenant in Chicago is covered, whether the lease is written or oral, and whether or not the tenant receives a housing subsidy. The main exception is a building with six or fewer units where the owner lives on-site. In that situation most RLTO protections do not apply, though the lockout ban in Section 5-12-160 and certain anti-retaliation rules still do.¹

Other excluded arrangements include hotels and rooming houses (unless you pay monthly and have stayed more than 32 days), hospitals and other institutional housing, dormitories and shelters, housing supplied as part of a job, and owner-occupied condos or co-ops.¹ If none of those describe your situation, assume the RLTO applies.

Security Deposit Rights

The deposit rules are the most heavily enforced part of the ordinance. A landlord who takes a deposit has to hold it in a federally insured, interest-bearing account at an Illinois bank or savings institution, kept separate from the landlord’s own money. If you pay the first month’s rent and deposit together, the landlord has five business days to move the deposit into a compliant account.²

You are entitled to a receipt at the time you pay, showing the amount, the date, and who received the payment. Electronic payments require an electronic receipt with the same information and a digital signature. No receipt means you can demand the deposit back immediately.²

Interest accrues at a rate the city sets each year. For 2026 the rate is 0.01%.³ Interest must be paid or credited within 30 days after each 12-month rental period.

After you move out, the landlord has 45 days to return the deposit with any interest owed. If any portion will be withheld for unpaid rent or damage beyond normal wear and tear, the landlord has 30 days to send an itemized statement listing the damage and the estimated or actual repair cost. When the statement uses estimates, paid receipts or a cost certification must follow within another 30 days.²

Violate any of these rules and the landlord owes two times the deposit, plus interest. That penalty applies to the account requirement, the receipt requirement, the 45-day return deadline, and short interest payments alike. For a deficient interest payment, you first have to give written notice; the landlord then has 14 days to pay the correct amount plus $50 or to send a written calculation. If the landlord does neither, the full double-damages penalty attaches.²

What the Landlord Must Give You at Lease Signing

Before you sign or move in, the landlord has to provide a city-produced summary of the RLTO. For written leases it must be attached to the agreement; for oral leases it must be delivered separately.⁴ The current summary is on the city’s Department of Housing website.⁵

The landlord also has to disclose any bedbug infestations or treatments at the unit or in the building during the previous 12 months, and identify the person or company authorized to manage the property and accept legal notices. If you never got the RLTO summary, that itself is a violation you can raise later.

Repairs, Habitability, and Heat

The RLTO requires landlords to keep units in compliance with every applicable provision of the municipal code.⁶ Certain failures are singled out as material: structural problems, broken plumbing or fixtures, bad heating equipment, no hot and cold running water, and missing or non-working fire safety equipment like smoke detectors and sprinklers.⁷

Chicago’s heat season runs September 15 through June 1. During that window your unit must reach at least 68°F from 8:30 a.m. to 10:30 p.m. and at least 66°F overnight, with all windows and exterior doors closed.⁸ The temperature rule sits in the building code, but because the RLTO requires compliance with all municipal code provisions, a heating failure is also an RLTO violation.

To use the ordinance’s remedies, put every repair request in writing. The written notice is what starts the clock. For most repairs the landlord has 14 days from receiving your notice to fix the problem. For a complete loss of an essential service like heat or running water, the expected response is much faster. Save every email, text, and letter you send.

Entry and Privacy

A landlord has to give at least two days’ notice before entering your unit. Notice can come by mail, phone, written note, or any other reasonable method made in good faith. Entry is limited to reasonable times, defined as 8:00 a.m. to 8:00 p.m. unless you agree otherwise.⁹

The reason for entry has to be legitimate: making repairs, delivering agreed services, or showing the unit to prospective buyers or tenants. You can’t unreasonably refuse those. A real emergency such as a burst pipe or fire is the one situation where the landlord can enter immediately without notice.⁹

Lease Terms That Can’t Be Enforced

The RLTO overrides any lease clause that conflicts with it. A lease may not require you to waive RLTO rights, authorize confession of judgment against you, limit the landlord’s liability for negligence or code violations, waive notice requirements, waive your right to a jury trial, require you to pay the landlord’s attorney fees except as separately provided by law, or give the landlord a shorter cancellation window than you have without a separate written notice. A landlord who tries to enforce any prohibited clause owes you two months’ rent in damages.¹⁰

Late fees are capped at $10 on the first $500 of monthly rent, plus 5% of any rent above $500. A lease that sets a higher late fee loses the entire late-fee provision, not just the excess, meaning the landlord collects nothing for lateness.¹⁰

Ending the Lease Early or Switching Tenants

You have the right to propose a sublease, and the landlord must accept any reasonable subtenant without charging extra for the arrangement.¹¹

Even without a replacement tenant, the landlord has a legal duty to mitigate damages. If you break the lease, the landlord has to make a good-faith effort to re-rent at a fair market rate. If the unit gets re-rented, you only owe the difference between your rent and the new tenant’s rent for the remaining term. If a good-faith effort fails, you owe the remaining rent plus reasonable advertising costs.¹¹ Leaving the unit empty and billing you the full remaining rent does not meet that duty.

Notice to End a Tenancy

For a month-to-month tenancy, either side can end things with at least 30 days’ written notice. A weekly tenancy requires at least seven days. If you have a written lease with a fixed end date, you can simply move out at expiration.

Chicago’s Fair Notice Ordinance adds extra time on the landlord’s side for longer-term tenants. A landlord who wants to end or decline to renew must give 60 days’ notice if you’ve lived there more than six months but less than three years, and 120 days’ notice if you’ve lived there three years or more. These rules apply to both leases and month-to-month arrangements. If the landlord shorts the notice, you can stay for the full period at your existing rent.¹² Fair Notice does not apply when an eviction is already proceeding for nonpayment or another lease violation.

Repair-and-Deduct, Rent Withholding, and Lockouts

When a landlord ignores a repair you’ve asked for in writing, and the fix is relatively cheap, you can hire a licensed professional and subtract the paid cost from your next rent. The repair can’t exceed the greater of $500 or half your monthly rent, and never more than one month’s rent. Send a written notice first explaining the problem and your intention to repair; wait the full 14 days; then get the work done to code and submit the paid receipt with your reduced rent.⁷

For serious habitability failures you can reduce or withhold rent to reflect the diminished value of the unit. This is riskier, because it invites an eviction filing, and you’ll need to show in court that the unit had genuine material code violations. Document everything: dated photos, written complaints, any city inspection reports, and all communications with the landlord.

Lockouts are flatly illegal. A landlord cannot change your locks, shut off your utilities, remove your belongings, or push you out without a court order, regardless of whether rent is overdue. In Illinois the only legal way to remove a tenant is a formal eviction carried out by the Cook County Sheriff. A landlord who locks you out faces city fines of $200 to $500 per day. In a civil case you can recover two months’ rent or double your actual damages, whichever is greater, and get possession of the unit back.

Protection From Retaliation

A landlord cannot punish you for using your rights. That means no termination, no rent increase, no reduction of services, no eviction threat, and no refusal to renew because you complained about code violations, asked for repairs, joined a tenant organization, or testified about building conditions.¹³

If you did any protected activity within one year before the landlord’s alleged act, the law presumes retaliation and the landlord has to prove otherwise. Winning a retaliation claim gets you two months’ rent or double your actual damages (whichever is greater), reasonable attorney fees, and the return of your security deposit with interest.¹³

Suing Under the RLTO

RLTO cases are filed in Cook County Circuit Court. In most RLTO disputes the prevailing plaintiff can recover court costs and reasonable attorney fees, which makes it practical to hire a lawyer even when the underlying damages are modest.¹⁴

Damage amounts depend on the violation. A security deposit violation alone can produce a judgment for two times the deposit plus interest. Lockout and retaliation claims each carry their own formulas. These can stack: a landlord who mishandles the deposit, retaliates after a repair complaint, and then changes the locks faces a combined judgment that climbs quickly, with the tenant’s legal fees paid on top.
