The Chicago Residential Landlord and Tenant Ordinance (RLTO)
The Chicago Residential Landlord and Tenant Ordinance, the RLTO, defines the rights and obligations of landlords and tenants across the city. It covers rent increases, lease agreements, and tenant protections in one place.
Purpose and scope of RLTO
The RLTO applies to most rental units in Chicago, with one main exception: owner-occupied buildings with six or fewer units. It sets out what landlords must do and what tenants can expect; both sides benefit from knowing it. The full ordinance text is available from the city.
Key provisions on rent increases
Under the RLTO, landlords must give tenants prior written notice before raising rent. The increase also has to appear clearly in the lease or an addendum. Skip either step and you are exposed to legal consequences, so the paperwork matters. The KSN Law overview of the RLTO lays out the compliance details in plain language.
Legal framework for rent increases in Chicago
Chicago's rent increase rules sit at the intersection of state preemption and local ordinance. Illinois bars rent control outright, but Chicago still has real guardrails on how and when landlords can raise rent.
Rent Control Preemption Act
The Illinois Rent Control Preemption Act prohibits any local government in the state from capping rents. Chicago cannot impose hard limits on rent increases for market-rate units. Landlords set the rent, but the city's notice rules and program-specific caps still apply. The RLTO compliance guide from KSN Law walks through where those limits kick in.
Rent increase limits and regulations
For all Chicago tenants, landlords must give at least 30 days' written notice before any rent increase takes effect. If the property participates in the Chicago Low-Income Housing Trust Fund program (CHLIHTF), increases are capped at 5% per year, so a ,000 unit can go up by no more than in a 12-month period. The city's Fair Notice Ordinance reinforces transparency throughout this process.
Lease terms and rent payment rules in Chicago
Chicago law addresses how rent is set, how long leases last, and what happens when a payment is late. Knowing these rules in advance keeps both sides out of unnecessary disputes.
Establishing rent and lease duration
Rent is agreed on before signing; both parties lock in the amount and the term at the start. Fixed-term leases, typically one year, give stability. Month-to-month leases offer more flexibility but also mean rent can change more often, provided the landlord gives proper notice each time. The Fair Notice Ordinance sets the minimum lead time before any such change takes effect.
Late fees and rent payment rules
Rent is due on the date specified in the lease. Late fees are permitted but must be reasonable, and tenants have to be told about them before they sign. Payment methods are flexible, checks, online portals, and electronic transfers all work. Clear, written communication up front prevents most fee disputes; both sides should keep records of what was agreed and what was paid.
Tenant rights regarding rent increases in Chicago
Chicago tenants have real protections when a landlord wants to raise rent. The law requires both adequate notice and a legitimate basis for any increase.
Legal justification for rent hikes
The Fair Notice Ordinance ties the required notice period to how long you have lived in the unit. Tenants past the three-year mark get at least 120 days' written notice before a rent change hits. That window gives you time to budget, negotiate, or start looking for alternatives. Any increase also must comply with the Fair Housing Act, it cannot target tenants on the basis of race, religion, sex, disability, familial status, or any other protected class.
Protection against unjust rent increases
If a landlord retaliates against you for reporting a housing violation by raising your rent, that is illegal. You can contest the increase and, if needed, contact a legal aid organization for guidance. These groups help tenants understand their options and can intervene when a landlord steps out of line.
Notice requirements for rent increases in Chicago
The notice period is not one-size-fits-all in Chicago, it scales with how long the tenant has been in the unit. Landlords need to know which tier applies before sending any notice.
Minimum notice period
Under the Fair Notice Ordinance, the required lead time breaks down like this: 30 days for leases under six months; 60 days for leases between six months and three years; 120 days for leases over three years. The longer window lets long-term tenants plan their finances or find new housing without being blindsided.
Delivering rent increase and eviction notices
Written notice is required, verbal notice does not count. You can serve it in person, by certified mail, or by whatever method the lease specifies. Keep proof of delivery; it can matter in a dispute. Illinois rent increase law is explicit about following the delivery method named in the agreement, so check the lease before choosing how to send.
Security deposit procedures in Chicago
Chicago's security deposit rules are among the most detailed in Illinois. Get them wrong and you are looking at penalties that can exceed the deposit itself.
Handling and returning security deposits
The Residential Landlord and Tenant Ordinance requires landlords to return the deposit within 45 days of move-out. Any deductions must be itemized and sent within 30 days. Miss those deadlines and you can owe the tenant double the deposit amount. In Cook County, the deposit cannot exceed 150% of one month's rent, and you cannot relabel other fees to get around that cap. Keep detailed records of the unit's condition and any costs you deduct.
Security deposit interest and regulations
For deposits held longer than six months, landlords must pay interest at the rate set each year by the City Comptroller. In 2023, that rate was 0.01%, a small number, but the obligation is real. You must also disclose which bank holds the deposit and provide tenants with an annual statement of interest earned. Both sides should track these requirements year to year, since the rate can change.
Eviction processes and protections in Chicago
Chicago spells out when a landlord can evict and what tenants can do to fight back. Both sides have defined roles in this process.
Grounds for eviction
The most common ground is nonpayment of rent. Other valid reasons include unauthorized subletting, property damage, and other lease violations. Before filing anything in court, a landlord must serve a proper eviction notice that states the breach and gives the tenant a window to fix it. The notice period varies by violation type; getting it wrong procedurally can sink an otherwise valid case. Read up on the full Illinois eviction process before you begin.
Tenant eviction protections and defenses
The RLTO gives tenants several ways to contest an eviction. If the landlord skipped a required step, wrong notice form, too short a notice period, a tenant can raise that as a defense. Retaliatory evictions, where a landlord files after a tenant reported a code violation, are prohibited. In rent-nonpayment cases, paying what is owed after receiving the notice can sometimes stop the process. Tenants facing eviction should review their rights in Illinois and speak with a lawyer; the Illinois Attorney General's guide is a good starting point.
Fair housing and anti-discrimination laws in Chicago
Federal law and Chicago's own ordinance work together to bar discrimination in rental housing. Landlords and tenants alike need to know where those lines are.
The Fair Housing Act and local ordinance
The Fair Housing Act, enacted as part of the Civil Rights Act of 1968, prohibits discrimination based on race, color, religion, sex, national origin, disability, and familial status. Chicago's Fair Housing Ordinance goes further, covering additional categories including source of income and gender identity. Together, these laws mean a landlord cannot turn you away, charge you more, or treat you differently based on who you are. Landlords who accept lawful income, such as housing vouchers, cannot refuse it as a reason to deny an application.
Preventing discrimination in renting
The Fair Housing Act prohibits denying housing based on race, gender identity, or any other protected class. Clear written rental policies and staff training reduce the risk of discriminatory practices taking root. If you believe you have been discriminated against, the Chicago Commission on Human Relations accepts complaints and can investigate. Knowing your rights is the first step; reporting violations is how those rights get enforced.
Maintenance and repair responsibilities in Chicago
Chicago sets clear expectations for who fixes what and how quickly. Landlords carry the heavier load here, but tenants have responsibilities too.
Landlord duties and timelines for repairs
Landlords must keep rental units up to city health and safety codes; that means functioning plumbing, heat, and electrical systems at a minimum. Under the RLTO, urgent repairs, no heat in winter, severe water leaks, must be addressed within 24 to 72 hours. Less critical issues get up to 14 days. Miss those windows and tenants have legal remedies: rent reduction, repair-and-deduct, or a formal complaint.
Tenant rights concerning habitability
You have the right to a safe, habitable unit. If your landlord ignores a repair request, you can withhold rent or fix the problem yourself and deduct the cost from future rent, but only after following the specific legal steps the ordinance requires. Put every repair request in writing and keep copies. The Illinois landlord and tenant rights laws set the standard; documentation is what lets you enforce it.
