Washington County sits in the rugged Ozark foothills of southeastern Missouri and carries a Low eviction risk score of 3.9/10 on the Eviction Risk Map. That places it 29th out of 115 Missouri eviction laws counties, meaning 28 counties carry higher eviction pressure and 86 are rated safer for landlords - putting Washington eviction laws County in the higher-risk third of the state despite its Low label. Landlords operating here should treat that distinction seriously: the county's combination of 25.3% poverty rate and a 33.4% average rent burden leaves renters with thin financial margins, and any income disruption can quickly escalate into a rent-and-possession filing.
The county's four tracked cities spread across a total population of 3,699 residents, with Potosi serving as the largest rental hub at 2,544 people and a score of 4/10. Irondale is the riskiest individual city at 3.7/10, while Mineral Point (3.8/10) and Caledonia (3.2/10) are the most stable. Average rents across the county sit at $856/month, and roughly 39.4% of residents rent rather than own - a meaningful renter share for a rural Missouri county. With average poverty at 25.3%, this is not a market where late-payment patterns are unusual; they are a structural feature of the local economy, not isolated incidents. Landlords should underwrite accordingly and maintain cash reserves for at least one to two vacancy cycles.
Missouri eviction law governs entirely under RSMo § 441 (Landlord and Tenant). For nonpayment of rent, Missouri allows a rent-and-possession action with no statutory cure period under RSMo § 535.010 - a landlord-favorable posture that keeps timelines short when tenants fail to pay. A material lease violation requires a 10-day notice under RSMo § 441.060, and a month-to-month tenancy termination requires 30 days notice under the same statute. Court filing costs run $70 to $180, sheriff lockout fees add another $40 to $150, and attorney fees in contested matters typically fall between $500 and $3,000. An uncontested eviction completes in roughly 21 to 45 days; a contested case can stretch to 45 to 120 days. Missouri has a statewide preemption of local rent control, so no municipality in Washington eviction laws County can cap rents independently. There is no just-cause eviction requirement under state law, and source-of-income is not a protected class. Fair housing complaints route through the Missouri Commission on Human Rights.
Washington eviction laws County's Low risk score reflects a landlord-friendly state statute and a short uncontested eviction timeline, but the county's high poverty rate and above-average rent burden mean cash-flow risk from tenant defaults is real and persistent.
