Despite tenant-friendly reputations in cities like Chicago, much of Illinois remains landlord-friendly—especially in downstate and suburban markets. With no statewide rent control, flexible default tenancy rules, and court enforcement of lease terms, Illinois offers a solid legal foundation for rental property owners. Investors focused on smaller cities and rural areas benefit from lower competition and streamlined legal processes.
Want to see how Illinois compares nationally? Start with our full guide to the most landlord-friendly states in the U.S.
Eviction, Tenancy Defaults, And Lease Enforcement
- Illinois law allows a 5-day notice to pay or vacate for nonpayment of rent, per 735 ILCS 5/9-209
- Landlords can file for eviction immediately after the notice period expires
- Default tenancy is month-to-month unless otherwise specified, allowing landlords to terminate with 30 days’ notice (765 ILCS 705/5)
- Courts enforce properly documented lease agreements, especially outside Chicago where local ordinances like the RLTO (Residential Landlord Tenant Ordinance) don’t apply
No Statewide Rent Control And Limited Regulation Downstate
- Illinois does not have statewide rent control, and the Rent Control Preemption Act (50 ILCS 825/) prohibits local governments from enacting it
- Chicago, Evanston, and Oak Park have tenant protection ordinances, but most of the state remains free from rent caps or advanced notice mandates
- Outside of Cook County, most municipalities do not require landlord registration or licensing, easing entry for investors in places like Rockford, Peoria, and Champaign
Security Deposit Flexibility With Local Variation
- Illinois law does not cap security deposits, but interest must be paid on them in some cities, including Chicago (Chicago RLTO Section 5-12-080)
- Statewide, deposits must be returned within 45 days with itemized deductions or 30 days if no deductions are taken (765 ILCS 710/1)
- Downstate landlords have far fewer deposit restrictions than those in major metro areas
Strong Investment Potential In Secondary Markets
- Illinois offers low property prices in many tertiary markets, particularly in southern and western counties
- Cities like Springfield, Decatur, and Moline have low competition and reliable demand from university students, regional workers, and retirees
- Investors can find favorable cash flow by targeting single-family homes, townhouses, or small multifamily buildings
- Property taxes are higher than average but often offset by low acquisition costs and strong rent-to-price ratios
Insurance Requirements Are Straightforward
- No special coverage mandates exist beyond standard landlord protections
- Most owners opt for landlord insurance that includes liability, fire, and income loss
- Owners of older buildings may benefit from equipment breakdown protection for boilers, plumbing, or HVAC systems
Bottom Line: Illinois Remains a Smart Bet for Strategic Landlords
Outside of Chicago, Illinois offers a pro-landlord legal structure with fast evictions, no rent control, and minimal licensing burdens. For those seeking control, stability, and long-term rental income, the state’s many underserved markets present a compelling opportunity in 2025.
