What Every Rental Property Owner Needs to Know Now
Illinois rental law changes for 2026 introduce new legal requirements that directly affect landlords, tenants, and rental property owners across Chicago and suburban Cook County. Some changes require immediate updates to lease agreements, while others impact how landlords enforce lease terms, handle rent payments, and comply with tenant ordinance rules.
If you own or manage residential property, rental units, or dwelling units in Chicago or the surrounding suburbs, understanding these updates now can help you avoid court costs, attorney’s fees, and unnecessary legal exposure within the landlord and tenant relationship.
1. New Lease Agreement Requirement: Summary of Rights for Safer Homes
Beginning January 1, 2026, Illinois law requires every residential landlord to include a state-issued Summary of Rights for Safer Homes as the first page of every written lease agreement and rental agreement, including lease renewal documents.
This requirement applies to all residential rental properties and is part of broader Illinois rental law changes for 2026 affecting written agreements that serve as a legally binding contract between landlord and tenant.
The summary explains tenant rights related to domestic or sexual violence protections, including:
The right to terminate the lease early in qualifying situations
Lock change and safety protections
Anti-discrimination provisions
Federal protections tied to the Violence Against Women Act
Key compliance steps
Update every lease agreement and written lease template to include the disclosure as page one
Ensure each tenant signs every page of the summary
Train staff or your property management company on delivery and documentation requirements
Common mistakes landlords make
Forgetting to include the disclosure with a lease renewal
Using outdated rental agreement templates
Failing to collect signatures from either the landlord or the tenant
Assuming prior written consent or oral agreements are sufficient
When a landlord fails to include a required disclosure, tenant remedies may apply and courts may award attorney’s fees or actual cost damages.
2. Eviction Filing Updates and Enforcement Risks in 2026
Another Illinois rental law change for 2026 affects eviction filings. Under updated Illinois law, landlords may no longer list minors as defendants in eviction actions.
This change impacts how landlords enforce lease terms related to unpaid rent, lease violations, or situations where a tenant fails to pay rent.
What landlords must do
Ensure eviction notice documents only name adult leaseholders
Confirm tenant responsibilities and occupant classifications in your system
Review how eviction notices, written notice, and termination date language is prepared
Mistakes to avoid
Filing eviction paperwork with outdated tenant lists
Failing to track ages of occupants in rental units
Misapplying eviction notice procedures during a fixed term lease
If a landlord files incorrectly and the case is dismissed, the landlord loses time, rent payments, and may incur additional court costs while unpaid rent continues to accrue.
3. No Major RLTO Change Is Occurring for 2026 (But Enforcement Still Matters)
For rental property owners in Chicago and throughout Cook County, including suburban Cook County, the Chicago Residential Landlord and Tenant Ordinance and Cook County RTLO continue to govern landlord and tenant obligations alongside Illinois law.
These tenant ordinance rules affect:
Security deposits and the tenant’s security deposit
How and when to return security deposits
Interest bearing account requirements
Notice period rules for rent increase, lease renewal, or lease termination
Essential services, habitability, and bed bugs
What landlords should review now
Whether lease terms align with Cook County and Chicago requirements
How much notice is required for rent increases or termination
Whether security deposits are properly handled and returned
Whether late fees, additional rent, and month’s rent provisions comply with governing law
When landlord accepts rent payments improperly or unreasonably withheld security deposits occur, tenant remedies and legal aid defenses become more likely.
4. Other Illinois Rental Law Changes Affecting Residential Property
While not entirely new, several legal shifts continue to affect residential landlords in 2026:
Expanded tenant protections now apply statewide, not just in Cook County
Fraud alert notification systems help protect residential property records
Increased scrutiny around written consent and written notice compliance
These rules apply to most residential property, including owner occupied buildings, owner occupied co ops, rooming houses, and employee’s quarters, but not non residential rental properties.
5. What Rental Property Owners Should Update Now
To comply with Illinois rental law changes for 2026, landlords should take action now.
Lease and rental agreement updates
Update written leases and rental agreements
Ensure the entire agreement reflects current applicable laws
Confirm lease terms address termination, lease violation, and rent payments
Clarify when tenant pays first month’s rent, last month’s rent, and security deposits
Operational processes
Standardize written notice and proper notice procedures
Track notice period requirements and termination dates
Ensure compliance when landlord decides to terminate the lease
Document situations where landlord agrees to exceptions
Documentation and compliance
Maintain signed disclosures in your property management system
Track unpaid rent, withholding rent claims, and lease enforcement actions
Review whether tenants are severally liable under the lease
Failure to update these processes increases risk when tenants fail to comply and disputes arise.
Why Professional Property Management Matters in 2026
As Illinois rental law changes expand, managing rental units across Chicago and Cook County becomes more complex. Compliance mistakes often occur when landlords manage multiple dwelling units without scalable systems.

Track rent payments and monthly rent accurately
Manage security deposits and interest requirements
Ensure eviction notice and termination procedures comply with Illinois law
Reduce exposure to attorney’s fees, court costs, and tenant remedies
At Landmark Property Management, compliance is built into every lease, renewal, and enforcement process so landlords can focus on their investment, not regulatory risk.
