Twin Falls County, Idaho Eviction Risk: Very Low

Twin Falls County scores 2.3/10 (Low) across its 8 incorporated cities, placing it rank 29 of 44 Idaho eviction laws counties on the eviction-risk index. That middle-of-the-pack state ranking reflects a market that, while not among Idaho eviction laws's most landlord-friendly corners, presents genuinely manageable operating conditions: average rent sits at $1,087, rent burden averages 30.2%, and renter households make up only 33% of the county's 68,757 residents. Landlords and investors entering Twin Falls County can expect a stable, low-drama leasing environment by most national benchmarks.

Intra-county risk runs a narrow band, from a floor of 1.5/10 in Murtaugh to a ceiling of 2.3/10 in the county seat, a spread of just 0.8 points. That compression means the county's risk profile is driven more by Idaho state law and regional economics than by wide variation in local tenant composition or local ordinances, a reassuring signal for operators with properties spread across multiple communities here.

The cities inside Twin Falls County

Twin Falls anchors the county with a population of 54,164 and carries the highest score at 2.3/10, still solidly Low. Three smaller communities, Hansen (2.2/10, pop. 1,225), Hollister (2.2/10, pop. 347), and Castleford (2.2/10, pop. 183), cluster just behind it. Buhl (pop. 4,673) and Filer (pop. 2,925) both score 2.1/10, while Kimberly (pop. 5,111) comes in at 2/10.

The clearest outlier is Murtaugh, a small rural community of 129 residents, scoring just 1.5/10, the lowest in the county. Investors focused exclusively on very low eviction risk may find Murtaugh and Kimberly eviction risk worth a closer look, though their rental markets are thin. The point is that even within a low-risk county, risk is hyper-local: a portfolio split between Twin Falls and Murtaugh carries meaningfully different profiles despite sharing the same county boundaries.

State-level laws that apply here

Every property in Twin Falls County operates under Idaho Code SS 6-301 et seq. (Forcible Entry and Detainer). For non-payment of rent or a lease violation, Idaho gives landlords a 3-day notice period before filing. End-of-term, no-cause terminations require a 30-day notice.

Investors underwriting deals here should review the full Idaho eviction costs breakdown to stress-test those scenarios.

Idaho offers a notably clean statutory environment at the landlord-operator level. Just-cause eviction requirements do not apply statewide, and Idaho state law preempts any local rent-control ordinance, so no municipality inside Twin Falls County can impose rent caps. Source-of-income is not a protected class under Idaho state law. For more on the procedural timeline and tenant rights, the Idaho eviction process guide covers the key steps from notice through writ of possession. Retaliation and habitability duties are addressed under Idaho Code SS 6-320.

With a county-wide poverty rate of 11.3% and renters accounting for 33% of households, Twin Falls County's risk floor is grounded in real affordability constraints rather than regulatory exposure; see the city grid above to compare individual community scores before targeting specific acquisitions.
