Why Chicago Has 9 Required Lease Disclosures
If you’re a landlord in Chicago, you already know the city doesn’t have rent control. Illinois preempted it statewide in 1997. What many landlords don’t realize is that Chicago’s Residential Landlord and Tenant Ordinance (RLTO) compensates for the lack of rent caps with one of the most prescriptive disclosure regimes in the country.
Every residential lease signed in Chicago must include or be accompanied by nine specific documents. This isn’t a suggestion — it’s a legal requirement with real penalties for non-compliance. A landlord who misses one disclosure can face the tenant terminating the lease, recovering actual damages, and in some cases, collecting attorney’s fees. For security deposit-related violations, the penalty escalates to 2x the deposit amount plus attorney fees.
Starting in 2026, a new statewide requirement — the Illinois Safer Homes Act — adds a tenth obligation for landlords across the state, though it functions as the ninth required document for compliance purposes since it replaces no existing requirement. This article covers all nine disclosures in detail, with the penalties for missing each one and practical advice for getting them right.
Disclosure 1: RLTO Summary
The most fundamental — and most commonly missed — disclosure is the city-published summary of the RLTO itself. The City of Chicago publishes an official summary document that outlines the rights and obligations of both landlords and tenants under the ordinance. This summary must be attached to every residential lease as a separate document.
The summary covers security deposit rules, late fee limits, lock change rights, repair obligations, and the tenant’s right to terminate a lease for landlord non-compliance. It is not sufficient to paraphrase or summarize the RLTO in your own words — you must use the official city-published version, which is available from the City of Chicago’s Department of Housing.
Penalty for missing this disclosure: The tenant may terminate the lease or recover actual damages. Courts have consistently held that failure to attach the RLTO summary is a material violation of the ordinance, and tenants have successfully used this as grounds to break leases without penalty.
Disclosure 2: Lead Paint Disclosure
Federal law requires lead paint disclosure for all residential properties built before 1978. In Chicago, where a significant portion of the housing stock predates 1978, this is one of the most common disclosure obligations. The disclosure has two components:
- The EPA pamphlet “Protect Your Family from Lead in Your Home” must be provided to the tenant
- A signed disclosure form in which the landlord either discloses known lead-based paint hazards or certifies that they have no knowledge of such hazards
Both parties must sign the disclosure form, and the landlord must retain a copy for at least three years. This is a federal requirement (42 U.S.C. § 4852d) enforced by both the EPA and HUD, with penalties of up to $19,507 per violation as of 2024 (adjusted annually for inflation).
For Chicago landlords with pre-war buildings, this disclosure is particularly important. Many buildings in neighborhoods like Lincoln Park, Lakeview, Wicker Park, and Logan Square were built well before 1978 and may contain lead-based paint on interior and exterior surfaces, window frames, and trim.
Disclosure 3: Radon Disclosure
Illinois requires radon disclosure for all rental properties under the Radon Awareness Act (420 ILCS 46). Landlords must provide tenants with the Illinois Emergency Management Agency (IEMA) radon guide, which explains the health risks of radon exposure and how to test for it.
Radon is a naturally occurring radioactive gas that enters buildings through cracks in foundations, floors, and walls. It is the second leading cause of lung cancer in the United States after smoking. The EPA recommends that all homes below the third floor be tested for radon, making this disclosure particularly relevant for basement and ground-floor units in Chicago’s extensive inventory of garden apartments and two-flats.
Penalty for missing this disclosure: Violation of the Radon Awareness Act can result in fines and may give the tenant grounds to void the lease. Additionally, if a tenant develops radon-related health issues and the landlord failed to provide the required disclosure, the landlord faces significant tort liability exposure.
Disclosure 4: Bed Bug Disclosure
Under Chicago’s Bed Bug Ordinance, landlords must disclose any known bed bug infestations in the unit or building within the past 120 days. This applies to both the specific unit being rented and to common areas or other units in the building if the landlord has knowledge of infestations there.
The disclosure must be made before the tenant signs the lease. Simply including a bed bug clause in the lease is not sufficient — the landlord must affirmatively disclose known infestations. The obligation extends to information the landlord “knew or should have known,” which means that ignoring tenant complaints about bed bugs does not eliminate the disclosure obligation.
Bed bugs are a persistent problem in Chicago’s dense multi-unit housing stock. The city has consistently ranked among the top cities in the U.S. for bed bug infestations, making this disclosure particularly relevant for landlords operating in older buildings with multiple units.
Disclosure 5: Heating Disclosure
If the landlord provides heat, the lease must specify the type of heating system used in the building (gas, electric, steam, etc.). If the tenant is responsible for heating costs, this must be clearly stated in the lease. This disclosure helps tenants understand their expected utility costs before committing to a lease.
In Chicago, where winters regularly bring temperatures below zero, heating costs can be a significant portion of a tenant’s monthly housing expense. A tenant who signs a lease expecting heat to be included, only to discover they are responsible for heating a poorly insulated vintage building with gas radiators, has grounds for a complaint under the RLTO.
Disclosure 6: Recycling Information
Chicago landlords must provide information about recycling services available at the property, including collection schedules and what materials are accepted. For buildings with fewer than five units, the city provides blue cart recycling pickup. For larger buildings, landlords must arrange for recycling service through a licensed hauler.
This disclosure is relatively straightforward but is frequently overlooked. The requirement comes from the city’s waste management ordinance and is intended to increase recycling participation rates in multi-unit buildings, where recycling compliance tends to be significantly lower than in single-family homes.
Disclosure 7: Security Deposit Receipt
Within 14 days of receiving a security deposit, the landlord must provide a written receipt that includes:
- The amount of the deposit received
- The name and address of the financial institution holding the deposit
- The interest rate on the account
The deposit must be held in a federally insured, interest-bearing account at an Illinois financial institution. Commingling the deposit with personal or operating funds is a violation. The annual interest rate for 2025–2026 is 0.01%, set by the City Comptroller.
Penalty for violations: This is where the RLTO gets expensive. Any violation of the security deposit provisions — including failing to provide the receipt within 14 days, failing to pay annual interest, or failing to hold the deposit in an interest-bearing account — triggers a penalty of 2x the full deposit amount plus reasonable attorney’s fees. For a $2,000 deposit, that is $4,000 in penalties plus legal costs, even if the landlord’s only mistake was not paying $0.20 in annual interest on time.
This penalty structure is one of the most aggressive in the country and is the single biggest source of RLTO litigation. Tenant attorneys in Chicago actively seek out security deposit violations because the penalties are statutory — meaning the tenant doesn’t need to prove actual harm to recover.
Disclosure 8: Safer Homes Act Summary (2026)
The Illinois Safer Homes Act, effective January 1, 2026, adds a new statewide requirement: every residential lease must include a state-issued Summary of Rights as the first page. This summary is published by the State of Illinois and outlines tenant rights including:
- Habitability requirements and the landlord’s duty to maintain
- Retaliation protections for tenants who report violations
- Security deposit rights and return timelines
- Right to request reasonable accommodations
- Domestic violence tenant protections
The tenant must acknowledge receipt of the summary by signing the first page. The Summary of Rights is a standardized document — landlords cannot modify it or substitute their own version.
Penalty for missing this disclosure: Penalties of up to $2,000 per violation, and the tenant may have grounds to void the lease. Since the requirement is statewide, it applies to all Illinois landlords, not just those in Chicago. However, for Chicago landlords, it adds to the existing nine-document RLTO burden.
Disclosure 9: Flood Disclosure
If the property is in a known flood zone or has a history of flooding, the landlord must disclose this information to the tenant before lease signing. Chicago has experienced several significant flooding events in recent years, particularly in neighborhoods with aging sewer infrastructure and in areas near the Chicago River and Lake Michigan.
The disclosure should include information about past flooding events, FEMA flood zone designations, and whether the landlord carries flood insurance. While flood insurance is not required for all properties, disclosure of flood risk is mandatory when the landlord has knowledge of the risk.
Garden apartments (below-grade units) in Chicago are particularly susceptible to flooding during heavy rain events. If you own a building with garden-level units and have experienced flooding in the past, this disclosure is critical. Failure to disclose can result in liability for tenant property damage and potential lease termination claims.
How to Stay Compliant
The most common mistake Chicago landlords make is not having a standardized lease packet that includes all nine disclosures. Here’s a practical approach:
- Create a master checklist of all nine disclosures and verify each one is included before every lease signing
- Use the official versions of city-published documents (RLTO summary, EPA lead paint pamphlet, IEMA radon guide, Safer Homes Act summary)
- Date and sign every disclosure — keep copies for your records for at least the duration of the tenancy plus the statute of limitations
- Track your security deposit deadlines — set calendar reminders for the 14-day receipt window and annual interest payment dates
- Update your packet annually — disclosure requirements change, interest rates change, and new laws (like the 2026 Safer Homes Act) add requirements

Frequently Asked Questions
What happens if I miss one of the nine required disclosures?
The consequences depend on which disclosure is missing. For most disclosures, the tenant may be entitled to terminate the lease or recover actual damages. For security deposit-related violations, the penalty is 2x the deposit amount plus attorney fees. For lead paint violations, federal penalties can reach $19,507 per violation. For the Safer Homes Act summary, penalties can reach $2,000.
Do these disclosures apply to month-to-month tenancies?
Yes. The RLTO disclosure requirements apply to all residential tenancies in Chicago, regardless of lease term. Month-to-month tenancies, fixed-term leases, and even oral agreements are all covered. The disclosures should be provided at the start of the tenancy.
Do the disclosures apply to single-family homes?
Most RLTO provisions, including the disclosure requirements, apply to buildings with six or more units. However, certain disclosures like lead paint (federal), radon (state), and the Safer Homes Act (state) apply regardless of building size. Additionally, the security deposit rules apply to all Chicago residential landlords, including those with single-family homes. Always verify which specific provisions apply to your property type.
Where do I get the official RLTO summary document?
The official RLTO summary is published by the City of Chicago Department of Housing. It is available for download from the city’s website. Do not use a third-party version or paraphrase the summary in your own words — courts have held that only the official city-published version satisfies the disclosure requirement.
Is the Safer Homes Act requirement retroactive?
The Safer Homes Act applies to leases signed on or after January 1, 2026. It does not require landlords to retroactively amend existing leases. However, when an existing lease renews or a new lease is signed with an existing tenant, the Summary of Rights must be included as the first page of the new document.
