Bonneville County, Idaho Eviction Risk: Very Low

Bonneville County scores 1.9/10 (Low) on the eviction-risk scale, placing it among the most landlord-friendly markets in Idaho eviction laws. With only 1 county ranked lower out of 44 statewide, operators here face conditions that favor decisive, lawful action when tenants default. Across the county's 7 cities, total population of roughly 95,898, and an average rent of $1,155, the operating environment is comparatively stable, with a rent-burden rate of 26.5% suggesting most renters can cover housing costs without chronic stress.

That said, the county is not monolithic. Risk scores range from 1.7 to 2.3 across its cities, a full point of separation that matters when choosing where to acquire or expand a rental portfolio. Investors focused on minimizing eviction exposure will find meaningfully different risk profiles depending on which part of Bonneville County they target.

The cities inside Bonneville County

The highest-risk city in the county is Swan Valley, scoring 2.3/10 with a population of 19,064 -- the second-largest city in the county. While 2.3 is still a Low score in absolute terms, it represents the upper end of local risk and warrants closer screening practices than the county average alone would suggest. Lincoln and Iona each score 2.2/10, and Ucon comes in at 1.7/10, clustering a band of mid-range risk in the smaller cities ringing the county's core.

The lowest-risk location by a wide margin is Idaho Falls, the county seat and by far the largest city, with a population of 67,725 and a score of 1.3/10. Swan Valley and Irwin both score 2.3/10, though their populations of 281 and 236 respectively make them niche markets. The takeaway for investors: risk is hyper-local, and Idaho Falls eviction risk dominates both the population base and the landlord-friendly end of the spectrum.

State-level laws that apply here

Idaho state law under Idaho Code § 6-301 et seq. (Forcible Entry and Detainer) gives landlords one of the shortest cure windows in the country. For non-payment of rent or a lease violation, the required notice period is just 3 days. A no-cause termination at end of term requires 30 days notice. Once notice expires and court action begins, an uncontested case typically resolves in 21 to 45 days; a contested case can extend to 45 to 120 days. Understanding the Idaho eviction process end-to-end matters because even a favorable statute can produce delays if paperwork is filed incorrectly.

Cost exposure is modest by national standards. Court filing fees run $160 to $260, sheriff lockout fees range from $30 to $120, and attorney fees, if counsel is retained, typically fall between $500 and $2,500. Idaho eviction costs are lower than most comparable western markets, which is one reason the county ranks so well. Idaho does not require just cause for eviction, imposes no rent cap, and state law preempts any local attempt to impose rent control, so landlords operate under a single, predictable statewide framework with no patchwork of local ordinances to track.

With a poverty rate of 10.6% and a renter share of 32.7%, Bonneville County's rental market is manageable in size and relatively stable in composition; see the city grid above for a granular breakdown of risk scores across all 7 cities.
