Dairy, Diversity, and the Magic Valley: Landlording in Jerome County, Idaho
Jerome County generates nearly a billion dollars in agricultural sales annually. That is not a figure typical of an Idaho county with 25,000 residents — it is a figure that reflects the extraordinarily concentrated and capital-intensive nature of the county’s dairy economy. With $519 million in milk sales in 2022 alone, representing 11.8% of Idaho’s total milk production, Jerome County punches well above its population weight in the state’s agricultural economy. And the economy is growing: Idaho Milk Products’ announcement of a $200 million facility expansion in 2024, expected to create more than 70 new jobs, signals continued investment in the infrastructure that underlies the county’s rental market. Idaho Code §§ 6-301 et seq. governs all residential tenancies here.
How Jerome County Became Idaho’s Dairy Powerhouse
The story of Jerome County’s dairy dominance is largely a story of the 1980s and 1990s California dairy migration. As California’s regulatory and cost environment became increasingly challenging for large-scale dairy operations — tightening environmental regulations, high land costs, water supply constraints, and labor costs — dairy farmers began looking east for alternatives. Idaho’s Snake River Plain offered volcanic soils that could grow abundant alfalfa hay for feed, a relatively stable water supply from the Snake River aquifer, a more accommodating regulatory environment, available land, and an established agricultural infrastructure. Operations moved, grew, and attracted the processing industry that needs to be near the milk supply. Agropur established its giant cheese facility in Jerome, processing millions of pounds of milk daily. Idaho Milk Products built its milk solids processing plant. Darigold and Commercial Creamery added additional processing capacity. The result was a dairy-industrial complex concentrated in Jerome County at a scale that few rural Idaho counties of any size could match.
The Hispanic and Latino Community
Jerome County’s dairy economy did not grow in a demographic vacuum. Large-scale dairy operations require significant labor for milking, feeding, herd health, sanitation, and facility maintenance — tasks that operate 24 hours a day, 365 days a year. This labor demand drew Hispanic and Latino workers, many from Mexico, who initially came as migrant workers and progressively established permanent households as year-round employment anchored their presence. Today approximately 38.5% of Jerome County’s population identifies as Hispanic or Latino — one of the highest proportions among Idaho’s 44 counties. The community is established, multigenerational in many cases, and deeply woven into the fabric of the county’s economy, culture, and civic life. Jerome’s schools, churches, businesses, and community organizations reflect this diversity in ways that distinguish the city from most of rural Idaho.
Jerome as a Planned Agricultural City
Jerome was not an organic frontier settlement — it was a planned agricultural city, platted in 1907 by the Kuhn Brothers’ North Side Twin Falls Canal Company as a railroad and irrigation hub designed to settle the arid north-side lands of the Snake River Plain. The first town lots were auctioned on September 30, 1907, and the city filled quickly with Midwestern farmers attracted by the promise of irrigated land. The regular grid streets, consistent block sizes, and central commercial district of modern Jerome reflect this planned origin. The county was named for Jerome Hill Kuhn, son of W.S. Kuhn, the company’s president — a detail that makes Jerome County one of the few Idaho counties named not for a president, explorer, or geographic feature, but for a young relative of a real estate developer.
Filing Evictions in Jerome
The Jerome County District Court at 233 W. Main Street serves the Fifth Judicial District. Main: (208) 644-2600; General: (208) 324-8811. Hours are Monday through Friday, 8:00 a.m. to 5:00 p.m. Idaho’s 3-day notice period for nonpayment of rent is among the most landlord-favorable in the Western United States. In a county with a significant immigrant population — approximately 17.9% foreign-born — landlords should ensure that all notices are served formally and that service is documented with a signed affidavit of service before filing at the courthouse. Spanish-language communication can facilitate the notice process but does not substitute for formal legal service requirements.
