Petroleum County, Montana Eviction Risk: Very Low

Petroleum County, Montana eviction laws earns an average eviction-risk score of 1.4/10 (Low), placing it among the least risky operating environments in the entire state. With only 1 incorporated place tracked and a total population of 204, this is one of Montana's most rural counties, and the numbers reflect that reality: 53 Montana counties score higher on the risk scale, and only 2 score lower. Landlords and investors entering this market face a tenant pool that is relatively stable, with an average rent burden of 25.3% and a poverty rate of just 6.4%, both of which point to manageable default exposure.

The intra-county score range runs from 1.4 to 1.4, meaning there is effectively no variation across the county's single city. Average rent sits at $820 per month, and the renter share of the housing stock is 21.2%, so the rental market here is thin by volume but consistent in character. For investors, the small scale is the defining feature: low absolute transaction volume, but a low-friction operating environment when tenants are in place.

The cities inside Petroleum County

Winnett is the only city in Petroleum County with scored data, carrying the county's sole risk reading of 1.4/10 (Low) against a population of 204. There is no intra-county spread to navigate here. The city's score reflects the same favorable indicators as the county average, and landlords operating in Winnett should expect conditions broadly consistent with a landlord-friendly Montana small-town market.

Because risk is hyper-local across Montana, even neighboring counties can vary meaningfully. Peer counties nearby include Garfield County at 1.4, Fallon County at 1.35, and Carter County at 2.01, illustrating that Petroleum County's profile is genuinely at the low end of the state's range, not just a statistical artifact of sparse data.

State-level laws that apply here

All rental activity in Petroleum County is governed by Montana state law, specifically MCA § 70-24 (Residential Landlord and Tenant Act). For non-payment of rent or a lease violation requiring cure, landlords must deliver a 3-day notice before filing. Terminating a tenancy at the end of a term with no stated cause requires a 30-day notice. Once filed, an uncontested eviction typically resolves in 21 to 45 days; a contested case can run 45 to 120 days. Total out-of-pocket costs depend on attorney involvement: court filing fees run $90 to $170, sheriff lockout fees add $40 to $125, and attorney fees range from $500 to $2,500. Understanding the full Montana eviction process before placing a tenant is the clearest way to protect a return. Montana does not require just cause for termination, and the state preempts local rent control, meaning no municipality can impose a rent cap, a detail worth confirming when reviewing Montana eviction costs and projecting long-term hold performance. Landlords must give 24 hours notice before entering an occupied unit under MCA § 70-24-303.

With a poverty rate of 6.4% and a renter share of 21.2%, Petroleum County's tenant base is small but financially stable relative to most of Montana eviction laws; see the city grid above for Winnett's individual score and population detail.
