Winnebago County, Illinois Eviction Risk: Moderate

Winnebago County carries an average eviction risk score of 5/10, placing it in the Moderate tier across all 14 cities tracked here. That middle-of-the-road average, however, conceals meaningful variation: individual city scores range from 4.8 to 5.6, a spread wide enough to shift a portfolio's risk profile depending on exactly where a property sits. Illinois eviction laws ranks this county 14th out of 102 counties for eviction risk, meaning only 13 counties statewide carry higher risk, and 88 are less risky. Landlords operating here are not in a worst-case market, but they are well above the state midpoint.

Context matters alongside those scores. The average rent across Winnebago County is $1,032 per month, with renters making up 37.9% of households. A poverty rate of 17.7% signals that a meaningful share of tenants are operating with limited financial cushion, which correlates directly with the elevated risk scores seen in several communities throughout the county.

The cities inside Winnebago County

The county's riskiest markets sit at 5.6/10, shared by Loves Park (population 23,502) and Durand. Roscoe (population 10,706) and South Beloit both score 5.5, while Machesney Park (population 22,630) and Rockton each score 5.4. These communities are suburban and small-city in character, yet their scores reflect elevated concentrations of rental stress relative to the county as a whole.

The county seat of Rockford, by far the largest city in the area at a population of 147,521, scores 4.8/10, which is the lowest risk reading in the county and the anchor pulling the overall county average down. That gap between Rockford at 4.8 and Loves Park at 5.6 illustrates how hyper-local risk is here: two communities a few miles apart can carry materially different operating conditions. Investors should evaluate each submarket on its own score rather than relying on the county average.

State-level laws that apply here

Illinois eviction laws eviction law, governed by 735 ILCS 5/9 (Forcible Entry and Detainer), sets out the notice periods that apply to every Winnebago County landlord. Nonpayment of rent requires a 5-day notice; a material lease violation triggers a 10-day notice; and a month-to-month holdover requires 30 days. Understanding the Illinois eviction process in full is essential before filing, because timelines stretch considerably once a case hits the courthouse. An uncontested case resolves in 30 to 60 days; a contested one can run 60 to 150 days.

Cost is the other pressure point. Court filing fees run $200 to $400, sheriff lockout fees add $60 to $200, and attorney fees typically range from $750 to $3,500. Illinois eviction costs, taken together, can push a single case well past $1,000 on the low end before accounting for lost rent during the proceeding. On the regulatory side, Illinois does not require just cause for non-renewal, and state law preempts local rent control ordinances, which keeps the statutory environment relatively straightforward for landlords compared to many other states. Illinois security deposit limits are governed at the state level, and source-of-income status is a protected class under Illinois fair housing rules administered by the Illinois Department of Human Rights.

With a poverty rate of 17.7% and renters comprising 37.9% of households, the financial pressure on Winnebago County tenants is real, and city-level risk scores in the grid above show where that pressure concentrates most sharply.
