Lewis and Clark County, Montana Eviction Risk: Very Low

Lewis and Clark County carries an average eviction-risk score of 2.3/10, placing it in the Low tier across all 13 cities tracked here. That figure sits in the higher-risk third of Montana's 56 counties, ranked 17th in the state, meaning 16 counties carry more risk and 39 are more landlord-friendly. For investors, that context matters: while the raw score is low on an absolute scale, the county is not the quietest corner of Montana either. Average rent runs $1,172 per month, and about 30.7% of households rent, giving the market real depth without the tenant-stress profile that drives up eviction rates.

Operating conditions across the county are generally favorable. Rent burden averages 26.3% of income, a level that suggests most renters can sustain their leases without severe financial strain. The poverty rate of 8.6% is low enough that widespread non-payment cycles are uncommon. Intra-county risk does vary, running from 1.8 to 2.7 depending on the submarket, so location selection within the county still matters.

The cities inside Lewis and Clark County

The highest-risk submarket in the county is Helena Valley West Central, scoring 2.7/10 with a population of 8,056. That score sits at the top of the local range and warrants closer scrutiny of tenant qualification standards for landlords active there. Helena itself, the county seat and by far the largest city at 33,639 residents, scores 2.3/10, in line with the county average. Helena Valley Southeast (population 9,108) also comes in at 2.3/10, and East Helena at 2.3/10 as well. These communities carry nearly identical risk profiles, so other factors such as vacancy rates and rent trends will differentiate them for investors.

At the lower end of the risk scale, Lincoln scores just 1.8/10, the most landlord-friendly reading in the county. Helena West Side comes in at 2.1/10. The spread from 1.8 to 2.7 is narrow by statewide standards but still meaningful: a landlord who picks submarkets deliberately can operate well inside the already-low county average. Risk is hyper-local even within a market this stable.

State-level laws that apply here

All landlords in Lewis and Clark County operate under MCA § 70-24, the Montana Residential Landlord and Tenant Act. For non-payment of rent or a lease violation, Montana state law requires only a 3-day notice before filing, one of the shorter cure windows in the region. No-cause terminations at end of term require a 30-day notice. Understanding the full Montana eviction process is essential before acting: an uncontested case typically resolves in 21 to 45 days, while a contested matter can stretch to 120 days. Montana eviction costs add up quickly, with court filing fees of $90 to $170, sheriff lockout fees of $40 to $125, and attorney fees ranging from $500 to $2,500 depending on complexity.

Montana does not require just cause for non-renewal, and state law preempts any local rent-control ordinance, so landlords face no patchwork of city-level caps. Montana security deposit limits and Montana tenant protections are set at the state level, keeping the rules consistent across every city in this county. Landlords must give 24 hours notice before entry under MCA § 70-24-303.

With a poverty rate of 8.6% and roughly 30.7% of residents renting, Lewis and Clark County's demand base is stable; the city-by-city scores in the grid above show where within the county that baseline holds strongest and where the 2.7/10 ceiling warrants more careful screening.
