Grundy County, Illinois Eviction Risk: Moderate

Grundy County, Illinois scores 4/10 (Moderate) on the eviction-risk index, placing it in the higher-risk third of all 102 Illinois eviction laws counties. Thirty-two counties in the state carry more risk for landlords, while 69 are comparatively more landlord-friendly, which means operators here face conditions that are meaningfully more challenging than the statewide average without reaching the most difficult tier. Across all 17 cities in the county, scores range from 3.7 to 4.6 out of 10, a spread that matters: a landlord buying in Minooka is making a materially different bet than one buying in Morris, even though both fall under the same county umbrella.

The county's average rent of $1,269 per month and a rent burden of 29.6% of renter income indicate that a meaningful share of tenants are financially stretched. With only 24.3% of residents renting, the rental market is relatively thin, which can make lease-up slower but also concentrates demand in specific corridors. The 7.8% poverty rate is below many comparable Illinois markets, providing some cushion against chronic nonpayment risk, but it does not eliminate it.

The cities inside Grundy County

Morris is the county seat and largest city at 14,898 residents, and it carries the county's highest risk score at 4.3/10, the only city to reach the top of the county's range. Seneca (3.9/10, population 2,450) and Godley (4.5/10) also sit at elevated levels within the county. These three represent the most demanding operating environments in Grundy County, and landlords active in Morris in particular should budget conservatively for turnover and legal costs.

On the lower end of the county's risk spectrum, Minooka (4.1/10, population 12,891), Coal City (4/10, population 5,317), and Braceville (4.1/10) score at the county minimum. The gap between Morris at 4.3 and Minooka at 3.9 may look modest on paper, but risk is hyper-local: tenant demographics, local court dockets, and housing stock condition all differ block by block. Investors should pull city-level data before settling on a target submarket rather than treating the county as a uniform operating environment.

State-level laws that apply here

All landlords in Grundy County operate under Illinois state law, specifically the Forcible Entry and Detainer Act at 735 ILCS 5/9. For nonpayment of rent, Illinois requires a 5-day notice before a landlord can file in court. A material lease violation triggers a 10-day notice, while a month-to-month holdover requires 30 days. Understanding the full Illinois eviction process is essential because an uncontested case still takes 30 to 60 days from filing to possession, and a contested matter can run 60 to 150 days. Illinois eviction costs add up quickly: court filing fees run $200 to $400, the sheriff lockout fee adds another $60 to $200, and attorney fees typically range from $750 to $3,500, depending on case complexity.

Illinois imposes no statewide rent control and does not require just cause for nonpayment or lease-violation evictions, which gives landlords meaningful flexibility compared to states with stricter frameworks. The state also preempts local governments from enacting rent control ordinances, so Grundy County municipalities cannot layer on additional rent restrictions. Source of income is a protected class under Illinois state law, administered by the Illinois Department of Human Rights, so landlords should review Illinois tenant protections and their own screening criteria with counsel to stay compliant.

With a 7.8% poverty rate and renters making up just 24.3% of the county's population, Grundy County's rental market is smaller and somewhat more stable than high-density Illinois eviction laws markets, but the city-level variation from 3.7 to 4.6/10 means submarket selection is the most important decision a landlord can make here; the city grid above breaks down each of the 17 cities individually.
