When is Rent Due?

Grace Period: Illinois does not generally regulate grace periods in most types of leases; however, it does forbid mobile home community landlords from charging late fees for 5 days following the due date (765 ILCS 745/12).

Unpaid Rent: Landlords issue a 5-day notice requiring full rent payment before initiating further actions (735 ILCS 5/9-209).

Late Fees

Landlords use the lease impose a reasonable non-punitive late fee for missed payments accordingly (IL AG Rights and Laws).

Mobile Homes: Illinois explicitly allows the greater of $20 or 20% as a late fee “for each month an occupant does not pay rent” (770 ILCS 95/7.10).

NSF Fee

Illinois allows the greater of a $25 fee or the expenses resulting from the bad check, accordingly (810 ILCS 5/3-806).

Security Deposit Maximum ($)

Illinois does not limit the security deposit a residential lease requires; therefore, leaving it up to the landlord and tenant.

Security Deposit Return($)

Returning to Tenant: The Illinois Security Deposit Act explicitly requires landlords deliver a tenant’s security deposit (and interest) within 45 days of lease termination (765 ILCS 710).

Itemized List: Landlords can deduct from the security to restore the premises, but must supply an itemized list of each expense (765 ILCS 710).

Landlord’s Right to Enter

Standard Entry: Illinois permits its counties to determine landlord rights to entry accordingly.

Emergency Entry: While Illinois does not explicitly permit entry during an emergency, some ordinances, such as those in Chicago and Cook County, allow emergency landlord access (Chicago Mun. Code § 5-12-050).

Absence

Landlords can issue a 5-day rent demand notice since Illinois strictly forbids forcible entry (735 ILCS 5/9-101; 735 ILCS 5/9-209).

Repair and Deduct

Illinois tenants deduct up to $500 of a half-month’s rent (whichever is less) if the landlord disregards a 14-day notice to repair. (765 ILCS 742/5)

Tenant Breaking a Lease (Early)

Duty To Mitigate: Illinois specifically states that landlords must take “reasonable efforts” to lower the cost of the damages resulting from a tenant’s early lease termination (735 ILCS 5/9-213.1).

Domestic Violence: Landlords accept a tenant’s 3-day notice of termination with evidence (e.g., police report), especially when it involves imminent threat (765 ILCS 750/15).

Active Military: Military service members may terminate their lease to report to duty or honor reassignment (50 USC § 3955).

Landlord Noncompliance: Landlords may not interrupt utilities, violate health and safety codes, or retaliate against tenants (765 ILCS 735/1.4.; 765 ILCS 735/0.01).

Landlord Harassment: In addition to prohibiting landlords from inappropriately terminating a tenant’s utilities, tenants:

Is an Oral Lease enforceable?

Illinois courts enforce oral leases (under one year); however, they can be difficult to prove in many cases(740 ILCS 80/).

Renewing a Lease

Illinois does not necessarily govern lease renewals beyond upholding the contract; however, each party must comply with its proper termination/renewal options (735 ILCS 5).

Unclaimed Property

Generally, the courts will enforce legal lease terms for unclaimed property; however, landlords cannot break the law or the lease with self-help methods like forcible entry and removing personal property (735 ILCS 5).

Landlord-Tenant Laws

The Landlord and Tenant Act (765 ILCS § 705) explicitly presents the current framework for landlord-tenant interaction. The Illinois Attorney General also offers a Landlord/Tenant Rights & Laws Fact Sheet.
