Essential Landlord-Tenant Laws for the Illinois Real Estate Exam

Last updated: April 2026

Whether you plan to specialize in residential leasing, property management, or traditional sales, a deep understanding of state-specific leasing regulations is critical for passing your licensing exam. Property management and leasing laws make up a significant portion of the state-specific questions you will face. This guide breaks down the landlord-tenant law essentials you need to know, providing a strong foundation as you work through the Complete Illinois Exam Guide.

Before diving into the statutes, ensure you are utilizing the best Illinois study materials and resources to reinforce these concepts through practice questions.

Key Illinois Landlord-Tenant Statutes

Illinois law heavily regulates the relationship between property owners and tenants to ensure fair housing, safe living conditions, and financial transparency. The Illinois Department of Financial and Professional Regulation (IDFPR) expects you to know the exact timelines and unit thresholds for the following acts.

Illinois Security Deposit Return Act (765 ILCS 710)

Handling security deposits is one of the most frequently tested topics on the Illinois real estate exam. The Security Deposit Return Act applies to residential properties containing five or more units. Here are the critical timelines you must memorize:

45 Days: The landlord must return the security deposit in full within 45 days of the tenant vacating the premises if no deductions are claimed.
30 Days: If the landlord intends to withhold any portion of the deposit for property damage, they must provide the tenant with an itemized statement of damages—along with estimated or actual repair receipts—within 30 days of the tenant vacating.

Exam Tip: Failure to comply with these timelines can result in the landlord being liable for damages equal to twice the amount of the security deposit, plus court costs and attorney's fees.

Illinois Security Deposit Interest Act (765 ILCS 715)

Not all landlords are required to pay interest on security deposits. The Illinois Security Deposit Interest Act specifically applies to residential properties with 25 or more units. If a landlord holds a deposit for more than six months, they must pay the tenant interest on that deposit annually. The interest rate is tied to the largest commercial bank in the state.

When a leased property is sold, the transfer of these security deposits and prorated rent must be meticulously recorded. You can see how these funds are credited and debited by reviewing our Illinois settlement statement walkthrough.

Eviction Procedures: The Forcible Entry and Detainer Act

In Illinois, a landlord cannot simply change the locks, turn off utilities, or remove a tenant's belongings. These illegal actions are known as "self-help evictions." Instead, landlords must go through the judicial eviction process, formally known as a Forcible Entry and Detainer action.

Statutory Notice Periods

Before filing for eviction, the landlord must serve the tenant with the appropriate written notice. The length of the notice depends on the reason for the eviction:

5-Day Notice: Used for non-payment of rent. The tenant has five days to pay the past-due rent in full. If they pay, the eviction process stops.
10-Day Notice: Used for lease violations (e.g., unauthorized pets, noise violations). Unlike the 5-day notice, the landlord is not legally required to give the tenant a chance to "cure" or fix the violation, though the lease terms may dictate otherwise.

Common Reasons for Eviction in Illinois

Understanding why evictions occur can help you grasp the practical application of these notices. Below is a breakdown of the most common causes for eviction proceedings in Illinois.

The Chicago Residential Landlord and Tenant Ordinance (CRLTO)

Because Chicago represents such a massive portion of the Illinois real estate market, the state exam frequently tests on the Chicago Residential Landlord and Tenant Ordinance (CRLTO). The CRLTO provides tenants with rights that go above and beyond standard state laws.

Applicability: The CRLTO applies to almost all residential rental units in Chicago. The most notable exception is owner-occupied buildings containing six or fewer units.

Key CRLTO Provisions to Know:

Security Deposit Commingling: Landlords must hold security deposits in a federally insured, interest-bearing account located in Illinois. The funds cannot be commingled with the landlord’s personal assets. (For more on how client funds are managed, review the Illinois escrow process timeline).
Landlord Entry: Landlords must provide at least two days (48 hours) notice before entering a unit, except in emergencies.
Strict Penalties: Violating CRLTO security deposit rules often results in strict liability, meaning the landlord must pay the tenant two times the deposit amount plus attorney's fees, regardless of intent.

Lease Terminations and Notice Requirements

When there is no definitive end date to a lease (such as in periodic tenancies), Illinois law dictates exactly how much notice either party must give to terminate the agreement:

Week-to-Week Tenancy: Requires 7 days' written notice.
Month-to-Month Tenancy: Requires 30 days' written notice.
Year-to-Year Tenancy: Requires 60 days' written notice (Note: farmland leases require 4 months' notice).

Practical Scenario: If a landlord wants to terminate a month-to-month lease on May 31st, they must serve the 30-day notice no later than May 1st. If they serve it on May 5th, the termination will not be effective until June 30th.

Frequently Asked Questions (FAQs)

1. What is the penalty for an Illinois landlord who illegally withholds a security deposit?

Under the Illinois Security Deposit Return Act, if a landlord acts in bad faith and fails to return the deposit or provide an itemized list of damages within the statutory timelines, they can be sued for double the amount of the wrongfully withheld deposit, plus court costs and reasonable attorney's fees.

2. Can an Illinois landlord use a "self-help" eviction?

No. Self-help evictions (such as changing locks, shutting off utilities, or removing doors) are strictly illegal in Illinois. Landlords must use the formal judicial eviction process known as Forcible Entry and Detainer.

3. Does the Security Deposit Interest Act apply to all Illinois landlords?

No. The requirement to pay interest on security deposits held for more than six months only applies to landlords who own or manage residential properties with 25 or more units.

4. How much notice is required to end a month-to-month lease in Illinois?

Illinois law requires a minimum of 30 days' written notice to terminate a month-to-month tenancy. The notice must align with the end of a rental period.

5. What is the difference between a 5-day notice and a 10-day notice?

A 5-day notice is specifically used for the non-payment of rent and gives the tenant five days to pay the balance to avoid eviction. A 10-day notice is used for breaches of the lease terms (like unauthorized roommates or pets) and typically does not require the landlord to give the tenant an opportunity to cure the violation.

6. Are there exceptions to the Chicago Residential Landlord and Tenant Ordinance (CRLTO)?

Yes. The most commonly tested exception on the exam is for owner-occupied buildings containing six or fewer units. If the owner lives in one of the units of a 4-flat, for example, the building is exempt from the CRLTO (though state laws still apply).
