765 ILCS 720/1

Short Title

↑
This Act shall be known and may be cited as the 'Landlord and Tenant Act'.
πŸ“ Illinois Comment
The primary Illinois landlord-tenant statute. Applies statewide to all residential and commercial tenancies unless a specific provision limits applicability.
πŸ’‘ General Comment
Illinois's statewide landlord-tenant law is relatively sparse compared to states like Massachusetts or California. Chicago's RLTO (Chicago Municipal Code Chapter 5-12) substantially expands tenant rights within the city. Always check local ordinances.
765 ILCS 720/2

Definitions

↑
As used in this Act: 'Landlord' means the owner, lessor, or sublessor of the dwelling unit or the building of which it is a part. 'Tenant' means a person entitled by written or oral agreement, subtenancy approved by the landlord, or by sufferance, to occupy a dwelling unit to the exclusion of others.
πŸ“ Illinois Comment
Basic definitions applicable to all Illinois residential tenancies governed by state law.
πŸ’‘ General Comment
Oral leases are valid in Illinois for terms of one year or less. All leases for more than one year must be in writing to be enforceable.
735 ILCS 5/9-201

Grounds for Eviction β€” Forcible Entry and Detainer

↑
A landlord may maintain an action for possession against a tenant who: (1) holds over after expiration of the lease term; (2) fails to pay rent when due; (3) violates a material term of the lease; or (4) is a tenant at will who has been given proper notice to terminate.
πŸ“ Illinois Comment
Illinois eviction proceedings are governed by the Forcible Entry and Detainer Act (735 ILCS 5/9-101 et seq.), not a separate landlord-tenant statute. Evictions are filed in the Circuit Court of the county where the property is located.
πŸ’‘ General Comment
Illinois evictions proceed in Circuit Court β€” not a small claims or MDJ-type court. Cook County has a dedicated Eviction Court (formerly called Landlord-Tenant Court). Outside Cook County, cases are filed in the civil division of the Circuit Court.
735 ILCS 5/9-207

5-Day Notice β€” Nonpayment of Rent

↑
When a tenant neglects or refuses to pay rent when due, the landlord may terminate the lease and recover possession by serving a written 5-day notice on the tenant demanding payment of rent or possession of the premises. If the tenant pays all rent due within the 5-day period, the notice is void and the tenancy continues.
πŸ“ Illinois Comment
Illinois requires only a 5-day notice for nonpayment of rent β€” shorter than most states. The notice must state the amount of rent owed. The tenant has the right to cure by paying within 5 days.
πŸ’‘ General Comment
The 5-day notice must be: (1) in writing; (2) state the amount of rent owed; (3) served properly β€” personal delivery, leaving with a person of suitable age at the residence, or posting on the main entrance door. Keep proof of service.
735 ILCS 5/9-210

10-Day Notice β€” Lease Violation

↑
When a tenant violates a material condition or covenant of the lease other than the payment of rent, the landlord may terminate the lease by serving a written 10-day notice on the tenant specifying the violation and demanding that the tenant remedy the violation or surrender possession. If the tenant remedies the violation within 10 days, the notice is void.
πŸ“ Illinois Comment
A 10-day notice is required for lease violations other than nonpayment of rent. The notice must describe the specific violation and give the tenant an opportunity to cure.
πŸ’‘ General Comment
Document all lease violations carefully before serving notice. The 10-day cure period is the tenant's right β€” if they remedy the violation, the tenancy continues. Keep copies of all notices and proof of service.
735 ILCS 5/9-213

30-Day Notice β€” Termination of Month-to-Month Tenancy

↑
A month-to-month tenancy may be terminated by either party by giving 30 days written notice before the end of the rental period. For tenancies of more than one month but less than one year, the notice required equals the interval between rent payments.
πŸ“ Illinois Comment
30 days written notice required to terminate a month-to-month tenancy. Notice must be given at least 30 days before the end of the rental period β€” not just 30 calendar days from the date of notice.
πŸ’‘ General Comment
Time notice carefully β€” a 30-day notice given mid-month may not be effective until the end of the following rental period. For a month-to-month tenant paying rent on the 1st, notice given on the 15th may require 45+ days before effectiveness.
735 ILCS 5/9-214

Notice β€” Tenancy at Will

↑
A tenancy at will may be terminated by either party by giving 30 days notice in writing.
πŸ“ Illinois Comment
Tenancies at will require 30 days written notice from either party.
πŸ’‘ General Comment
A holdover tenant after a fixed-term lease becomes a tenant at sufferance. Pursue eviction promptly β€” continued acceptance of rent may convert the holdover into a month-to-month tenancy.
765 ILCS 710/1

Security Deposit Return Act

↑
A landlord of a residential property who receives a security deposit from a tenant must return the deposit to the tenant within 30 days after the tenant vacates the premises, or within 45 days after the tenant vacates if the landlord intends to make deductions for damage. If deductions are made, the landlord must provide an itemized statement of the deductions. Failure to return the deposit or provide an itemized statement entitles the tenant to twice the amount of the deposit, plus court costs and attorney fees.
πŸ“ Illinois Comment
Illinois's Security Deposit Return Act requires return of the deposit within 30 days (45 days if deductions are claimed) with an itemized statement. Wrongful withholding carries a penalty of double the deposit amount plus attorney fees.
πŸ’‘ General Comment
Return deposits promptly. If deductions are claimed, provide a written itemized list within 45 days. Penalties for non-compliance are significant β€” double damages plus attorney fees. Document property condition at move-in and move-out with photos and a written checklist signed by the tenant.
765 ILCS 710/1.1

Security Deposit β€” Interest Requirement

↑
A landlord who holds a security deposit for a residential rental unit for more than 6 months must pay interest on the deposit at the rate equal to the interest paid by the largest commercial bank in Illinois on minimum deposit passbook savings accounts as of December 31 of the preceding year. Interest must be paid annually to the tenant or credited to the next month's rent.
πŸ“ Illinois Comment
Illinois requires landlords to pay interest on security deposits held more than 6 months. The interest rate is based on the largest commercial bank in Illinois passbook savings rate, announced annually.
πŸ’‘ General Comment
Track interest obligations carefully. Annual interest must be paid to the tenant or credited to rent. Failure to pay interest is a violation that can result in liability. Chicago's RLTO has separate and more detailed interest requirements.
765 ILCS 720/1 (Damage)

Security Deposit β€” Damage Deductions

↑
A landlord may deduct from a security deposit only amounts necessary to cover: (1) unpaid rent; (2) damage to the premises beyond normal wear and tear; and (3) other amounts the tenant owes under the lease. The landlord may not deduct for normal wear and tear.
πŸ“ Illinois Comment
Deductions are limited to unpaid rent, damage beyond normal wear and tear, and other lease-authorized charges. Normal wear and tear is not deductible.
πŸ’‘ General Comment
Establish a consistent standard for what constitutes normal wear and tear versus damage. Document all deductions with written estimates, invoices, or receipts. Vague or undocumented deductions are easily challenged.
765 ILCS 735/1

Implied Warranty of Habitability

↑
In every lease of residential premises, the landlord covenants that the premises will be habitable throughout the term of the lease. A material non-compliance with this warranty by the landlord entitles the tenant to terminate the lease upon 14 days written notice to the landlord, or to pursue other remedies as provided by law.
πŸ“ Illinois Comment
Illinois recognizes an implied warranty of habitability in all residential leases. The landlord must maintain the property in a condition fit for human habitation throughout the tenancy. Tenants may terminate the lease after 14 days written notice of a material habitability failure.
πŸ’‘ General Comment
Respond to habitability complaints promptly and in writing. Document all repairs. A material habitability failure β€” no heat, no water, major structural defects, pest infestation β€” gives the tenant the right to terminate with 14 days notice or pursue rent withholding remedies in Cook County.
765 ILCS 735/2

Rent Withholding β€” Material Non-Compliance

↑
If a landlord materially fails to comply with the terms of the lease or with applicable building codes affecting health and safety, and the tenant gives 14 days written notice of the non-compliance and the landlord fails to remedy it within that period, the tenant may: (1) terminate the lease; (2) withhold rent in an amount reasonably proportionate to the diminution in value; or (3) repair the deficiency and deduct the cost from rent, subject to certain limits.
πŸ“ Illinois Comment
After 14 days written notice of a material habitability failure, Illinois tenants may withhold rent proportionate to the diminution in value, terminate the lease, or repair and deduct. The repair-and-deduct remedy is capped at the lesser of $500 or one-half month's rent.
πŸ’‘ General Comment
Habitability complaints must be taken seriously. Repair within 14 days of written notice. If repairs are delayed, document the reason and communicate in writing. Cook County RLTO has more expansive tenant remedies than state law.
765 ILCS 720/2

Anti-Retaliation

↑
A landlord may not retaliate against a tenant by terminating the tenancy, increasing rent, decreasing services, or threatening to bring an eviction action for exercising a legal right, including: complaining to a governmental authority about a code violation; organizing or joining a tenants union; or testifying in a proceeding concerning the rental unit. There is a rebuttable presumption of retaliation if adverse action occurs within 12 months after the tenant exercises a protected right.
πŸ“ Illinois Comment
Illinois anti-retaliation protection is broad β€” 12-month presumption of retaliation following a tenant's exercise of any legally protected right. Landlord must rebut the presumption with evidence of a legitimate non-retaliatory reason.
πŸ’‘ General Comment
Do not take adverse action against a tenant within 12 months of any complaint, code enforcement contact, or exercise of tenant rights. If legitimate reasons for adverse action exist, document them thoroughly before acting.
Chicago Municipal Code Β§ 5-12-010

Chicago RLTO β€” Applicability

↑
The Chicago Residential Landlord and Tenant Ordinance (RLTO) applies to all rental dwelling units in the City of Chicago except: owner-occupied buildings with 6 or fewer units; units in hotels, motels, and rooming houses; school dormitories; and certain other institutional housing. The RLTO is substantially more protective of tenants than Illinois state law.
πŸ“ Illinois Comment
The Chicago RLTO is one of the most comprehensive local landlord-tenant ordinances in the United States. It applies to the vast majority of rental units in Chicago and substantially expands tenant rights and landlord obligations beyond Illinois state law.
πŸ’‘ General Comment
If your property is in Chicago, you must comply with BOTH Illinois state law AND the Chicago RLTO. The RLTO governs security deposits, habitability, landlord entry, tenant remedies, prohibited lease provisions, and more β€” often with stricter requirements than state law. See the Illinois City Ordinances Guide for full Chicago RLTO details.
Chicago Municipal Code Β§ 5-12-080

Chicago RLTO β€” Security Deposit Interest

↑
A landlord who holds a security deposit for a residential rental unit in Chicago must pay interest on the deposit at the rate established annually by the City Comptroller. The interest rate is based on the average of the rates offered by the five largest commercial banks in Chicago on minimum deposit savings accounts. Interest must be paid or credited to the tenant each year.
πŸ“ Illinois Comment
Chicago has its own security deposit interest rate, set annually by the City Comptroller β€” separate from the state requirement. The Chicago rate and the state rate may differ. Landlords in Chicago must use the Chicago rate.
πŸ’‘ General Comment
Check the Chicago Comptroller's website each year for the current security deposit interest rate. Failure to pay interest entitles the tenant to terminate the lease, sue for the deposit plus interest plus damages, and attorney fees.
Chicago Municipal Code Β§ 5-12-110

Chicago RLTO β€” Tenant Remedies

↑
Under the Chicago RLTO, if a landlord fails to maintain the premises in a habitable condition, fails to provide essential services, or otherwise materially breaches the lease, the tenant may: (1) withhold rent in an amount reasonably proportionate to the diminution in value; (2) repair and deduct (up to $500 or one-half month's rent per occurrence); (3) obtain substitute housing and deduct the cost from rent; or (4) terminate the lease. The landlord must be given 14 days written notice before the tenant exercises these remedies.
πŸ“ Illinois Comment
The Chicago RLTO's tenant remedies are broader and more explicit than Illinois state law. Tenants may obtain substitute housing and charge the cost to the landlord β€” a remedy not available under state law.
πŸ’‘ General Comment
Respond to all habitability complaints in Chicago within 14 days of written notice. Document repairs. Chicago tenants have multiple remedies and are frequently represented by legal aid attorneys familiar with the full scope of RLTO protections.
Chicago Municipal Code Β§ 5-12-130

Chicago RLTO β€” Prohibited Lease Provisions

↑
The Chicago RLTO voids any lease provision that: waives the tenant's right to a jury trial; allows the landlord to confess judgment against the tenant; limits the landlord's liability for negligence; allows the landlord to terminate the tenancy for the tenant's exercise of legal rights; or waives any right provided by the RLTO. Any such provision is void and unenforceable.
πŸ“ Illinois Comment
Chicago leases must not contain provisions that waive RLTO rights. Even if a tenant signs a lease with prohibited provisions, those provisions are void as a matter of law.
πŸ’‘ General Comment
Have your Chicago lease reviewed by an Illinois attorney familiar with the RLTO before using it. Standard national lease forms frequently contain provisions that are void under Chicago law.
Chicago Municipal Code Β§ 5-12-160

Chicago RLTO β€” Attorney Fees

↑
In any action arising out of a landlord's or tenant's application of the RLTO, the prevailing party is entitled to all court costs and reasonable attorney fees.
πŸ“ Illinois Comment
The Chicago RLTO's two-way attorney fee provision means that a landlord who successfully pursues a claim against a tenant is entitled to attorney fees β€” but so is a tenant who successfully pursues a claim against a landlord. This provision incentivizes compliance by both parties.
πŸ’‘ General Comment
The attorney fee provision cuts both ways. Landlords who violate the RLTO face not only damages but also the tenant's attorney fees. Compliance is substantially cheaper than litigation in Chicago.
765 ILCS 735/8.5

Landlord Entry β€” Notice Required

↑
A landlord may enter a dwelling unit only with the consent of the tenant, except in cases of emergency. When entry is necessary for non-emergency purposes (repairs, inspections, showing the unit), the landlord must provide at least 24 hours advance notice and may only enter at reasonable times.
πŸ“ Illinois Comment
Illinois requires at least 24 hours advance notice for non-emergency landlord entry. Emergency entry (fire, flood, dangerous condition) is permitted without notice.
πŸ’‘ General Comment
Give written notice of entry whenever possible. Document emergency entries with a written record of the reason. Chicago RLTO has the same 24-hour notice requirement but specifies that entry must be between 8am and 8pm unless the tenant consents to other times.
765 ILCS 77/1

Residential Real Property Disclosure Act β€” Lead Paint

↑
Landlords of residential property built before 1978 must comply with federal lead-based paint disclosure requirements under 42 U.S.C. Β§ 4852d. Before signing a lease, the landlord must: (1) provide the tenant with an EPA-approved lead paint disclosure form; (2) disclose any known lead-based paint hazards; and (3) provide the EPA pamphlet 'Protect Your Family from Lead in Your Home.'
πŸ“ Illinois Comment
Federal lead paint disclosure is required for all pre-1978 residential rental properties in Illinois. This is a federal requirement that applies in every state.
πŸ’‘ General Comment
Lead paint disclosure is non-negotiable for pre-1978 properties. Keep signed copies of disclosure forms in your records. Failure to disclose known lead hazards exposes landlords to significant federal liability.
765 ILCS 750/1

Safe Homes Act β€” Domestic Violence

↑
A tenant who is a victim of domestic violence, sexual violence, or gender violence may terminate a lease early by providing the landlord with written notice and documentation of the abuse (such as a court order, police report, or certification from a qualified third party). The tenant must give at least 3 days advance notice and may not be liable for more than 2 months rent as early termination liability.
πŸ“ Illinois Comment
Illinois's Safe Homes Act allows domestic violence victims to terminate leases early with 3 days notice and proper documentation. Early termination liability is capped at 2 months rent.
πŸ’‘ General Comment
Never penalize a tenant beyond the statutory maximum for early termination under the Safe Homes Act. Require proper documentation before releasing the tenant from lease obligations. Do not discriminate against applicants based on domestic violence victim status.
50 ILCS 825/1

Rent Control Preemption Act

↑
No unit of local government, including any home rule unit, may enact, maintain, or enforce any ordinance or resolution that would have the effect of controlling the amount of rent charged for leasing private residential or commercial property.
πŸ“ Illinois Comment
Illinois state law preempts all local rent control ordinances. No Illinois city, county, or municipality β€” including Chicago β€” may enact rent control or rent stabilization. This has been state law since 1997.
πŸ’‘ General Comment
No Illinois municipality has rent control. Landlords may set rents at market rates and increase rents upon lease renewal with proper notice. Chicago's RLTO does not include rent control.
775 ILCS 5/3-102

Illinois Human Rights Act β€” Fair Housing

↑
It is a civil rights violation for any person to: refuse to rent or sell housing; discriminate in the terms, conditions, or privileges of a rental; or publish advertising indicating a preference or limitation based on: race, color, religion, sex, national origin, ancestry, age (40+), order of protection status, marital status, physical or mental disability, military status, sexual orientation, or familial status.
πŸ“ Illinois Comment
The Illinois Human Rights Act adds several protected classes beyond federal law, including: ancestry, age (40+), order of protection status, marital status, military status, and sexual orientation. Chicago adds additional local protected classes.
πŸ’‘ General Comment
Apply consistent, documented screening criteria to every applicant. Illinois's fair housing protections are broader than federal law. Chicago adds source of income (Section 8 vouchers) as a protected class under the RLTO.

πŸ” Tenant Screening in Illinois

Understanding Illinois's landlord-tenant law is the foundation of good property management. The next step is screening tenants before they sign the lease β€” before these laws ever need to be invoked.
