Johnson County, Iowa Eviction Risk: Moderate

Johnson County, Iowa eviction laws carries an average eviction-risk score of 4/10 (Moderate) across its 13 cities, placing it 7th out of 99 Iowa counties by risk, meaning only 6 counties statewide present a harder operating environment for landlords. That ranking puts it firmly in the higher-risk third of Iowa, so investors considering the county should not mistake the Moderate label for easy territory. The county's 44.8% renter share and an average rent burden of 33.1% of income signal a tenant base under real financial pressure, which tends to correlate with higher eviction frequencies over time.

Within the county the risk picture is anything but uniform. Scores span from 2.6 to 4.7, a 2.1-point spread that makes city-level due diligence essential before committing capital. The average rent across the county is $1,122, but that figure masks meaningful variation by submarket. Landlords who underwrite to county averages without drilling down to the specific city will consistently misprice risk.

The cities inside Johnson County

Coralville is the county's highest-risk jurisdiction, scoring 4.7/10 with a population of 23,234. That score reflects conditions materially worse than the county average, and landlords there should budget accordingly for turnover and collection friction. Swisher comes in second at 4.3/10 despite its smaller size (1,182 residents), suggesting concentrated pressures that are not diluted by scale. Iowa City, the county seat and largest city at 75,752 residents, scores 4.1/10, above the county average and carrying the additional complexity of a large university-adjacent rental pool with high seasonal churn.

Conditions improve sharply toward the county's smaller suburbs. North Liberty (3.5/10, population 21,125) and Tiffin (3.2/10, population 5,737) represent meaningfully lower-risk environments for buy-and-hold operators. Lone Tree scores 3.2/10 as well, matching Tiffin at the lower end of the county range. Solon at 3.3/10 similarly offers more landlord-favorable conditions relative to the Coralville eviction risk-to-Iowa City eviction risk corridor. The gap between the county's riskiest and most landlord-friendly cities is substantial enough that portfolio geography inside Johnson County matters as much as the decision to enter the county at all.

State-level laws that apply here

Every landlord in Johnson County operates under Iowa Code § 562A (Uniform Residential Landlord and Tenant Law), the statewide framework that governs notice periods, entry rights, and habitability duties. For non-payment of rent, Iowa law requires only a 3-day notice before a landlord may file, which is among the shorter windows in the Midwest. Lease-violation cures require a 7-day notice, and no-cause terminations at end of term require 30 days. Landlords must give 24 hours notice before entering a unit. A full walkthrough of the Iowa eviction process, including filing steps and court timelines, is available in the statewide guide. Iowa does not require just cause for non-renewal, and the state preempts local rent control ordinances, so no Johnson County municipality may impose its own rent caps.

Cost exposure on an Iowa eviction is real. Court filing fees run $95 to $200, sheriff lockout fees add $50 to $150, and attorney fees, while variable, typically range from $500 to $2,500. Uncontested cases close in 21 to 40 days; contested matters stretch to 45 to 100 days. Iowa eviction costs are detailed further in the statewide guide for landlords who want a line-item breakdown. Iowa security deposit limits and Iowa tenant protections round out the statutory framework landlords should review before signing leases in this county.

With a poverty rate of 18.6% and nearly 44.8% of residents renting, financial stress is spread broadly across Johnson County, which helps explain why Coralville and Iowa City carry the scores they do; the city-level grid above is the fastest way to spot where that pressure concentrates.
