Idaho landlord guide — American Falls (county seat; US’s largest town relocation), American Falls Reservoir, Snake River agriculture, Oregon Trail & Idaho Code §§ 6-301 et seq.
🏛️ County Seat: American Falls (~4,863) 👥 Population: ~7,878 (2020 census) 🚰 History: Largest gov’t-sponsored town relocation in US history (1925)
Power County sits in southeastern Idaho along the Snake River, created in 1913 from a partition of Cassia County. Its name honors an early hydroelectric power plant built at American Falls in 1902 — one of the first hydroelectric facilities in Idaho. The county covers 1,443 square miles of Snake River Plain, including the 55,860-acre American Falls Reservoir created by the American Falls Dam (completed 1927), which provides both irrigation water for the county’s agricultural lands and a major recreational amenity for fishing and boating. Approximately 159,000 acres in eastern Power County are part of the Bannock-Shoshone Fort Hall Indian Reservation.
American Falls, the county seat, carries one of the most remarkable stories in American local history. A waterfall on the Snake River — named for a party of American trappers whose boat was lost over the falls — gave the town its name. When the construction of the American Falls Dam in the 1920s threatened to flood the original townsite, the federal government undertook the largest government-sponsored town relocation in United States history: between 1925 and 1926, more than 300 buildings were moved to higher ground, with the residents, businesses, and civic institutions of American Falls essentially picking up and moving their entire town. The centennial of this event was celebrated in 2025. Today the reservoir covers the original townsite, and American Falls is a thriving agricultural community of approximately 4,863 residents serving as the commercial hub for Power County.
All landlord-tenant matters in Power County are governed by Idaho Code §§ 6-301 et seq. (evictions), §§ 6-320 and 6-321 (security deposits), and §§ 55-208 and 55-307 (tenancy and notice). Eviction actions are filed as Unlawful Detainer proceedings at the Power County District Court (Sixth Judicial District), 543 Bannock, Room 101, American Falls, ID 83211, (208) 226-7611. Idaho prohibits rent control statewide.

Power County Local Ordinances & Landlord Rules
Idaho state law governs landlord-tenant matters throughout Power County — no supplemental local ordinances
Category
Details
No Local Ordinances
Neither Power County nor the City of American Falls has enacted local landlord-tenant ordinances supplementing Idaho state law. No rental registration, no source-of-income protections, no supplemental notice requirements. Idaho Code §§ 6-301 et seq. applies exclusively throughout the county.
Rent Control
Idaho Code § 55-304 prohibits rent control statewide. No jurisdiction in Power County may enact rent stabilization. Month-to-month rent increases require 30 days’ prior written notice before the rent due date.
Security Deposit
No statutory cap under Idaho law. Idaho Code § 6-321 requires return of the deposit or itemized written deductions within 21 days of tenancy end (up to 30 if lease specifies). Failure to comply forfeits the right to withhold and exposes the landlord to 3× damages plus attorney fees. Move-in and move-out condition documentation is essential.
Agricultural Economy and Pocatello Commuter Demand
American Falls sits on I-86 approximately 25 miles west of Pocatello and 35 miles southeast of Blackfoot. This I-86 corridor position gives American Falls modest commuter demand from workers employed in Pocatello’s larger economy (health care, retail, Idaho State University, government). The Portneuf Medical Center and ISU in Pocatello draw workers who may choose American Falls for affordable housing and a smaller community lifestyle. This commuter demand supplements the county’s core agricultural employment base and provides a more consistent rental tenant pool than purely agricultural counties without commuter access.
Fort Hall Reservation Context
Approximately 159,000 acres in eastern Power County fall within the Bannock-Shoshone Fort Hall Indian Reservation. Landlord-tenant matters on tribal trust land involve jurisdictional questions beyond Idaho state law and may require tribal court or federal jurisdiction analysis. Landlords should consult a licensed Idaho attorney with expertise in tribal jurisdiction before managing property on trust land within Power County.
Diverse Agricultural Workforce
Power County’s agricultural economy — potatoes, sugar beets, wheat, and barley in the irrigated Snake River valley; dryland cattle and sheep ranching in the Arbon and Rockland Valleys — has historically relied on a diverse labor force. The county’s Hispanic and Latino population has grown from 7.3% in 1980 to over 25% today, reflecting the established nature of this agricultural community. Landlords must apply screening criteria consistently and without discrimination on the basis of national origin, race, or language. Fair housing criteria (income verification, rental history, court records) applied uniformly to all applicants is the legal and practical standard.

⚠️ Watch Out
Idaho is very landlord-friendly with fast timelines. 3-day notice is one of the shortest in the nation. No state-mandated cure period beyond the notice.
Serve the required notice based on the eviction reason (nonpayment or lease violation).
Wait for the notice period to expire. If tenant cures the issue (where allowed), the process stops.
File an eviction case with the Magistrate Court. Pay the filing fee (~$166).
Tenant is served with a summons and has the opportunity to respond.
Attend the court hearing and present your case.
If you prevail, obtain a writ of possession from the court.
Law enforcement executes the writ and removes the tenant if necessary.
⚠️ Disclaimer: This page provides general information about Idaho eviction laws and does not constitute legal advice.
Eviction procedures can vary by county and may change over time. Local jurisdictions may have additional requirements or tenant protections.
For specific legal guidance, consult a qualified Idaho attorney or local legal aid organization.
🔍 Reduce Your Risk Before Signing a Lease:
Idaho landlords who screen tenants carefully before signing a lease significantly
reduce their risk of ending up in eviction court. Understanding
tenant screening in Idaho —
including background checks, credit history, income verification, and rental references — is one of the most
cost-effective steps you can take to protect your rental property. Before you ever need Idaho's
eviction process, proper tenant screening can help
you identify red flags early and avoid problem tenancies altogether.

The Town That Moved: Landlording in Power County, Idaho
In 1925, the residents of American Falls, Idaho, did something unprecedented in American civic history: they moved their entire town. The construction of the American Falls Dam on the Snake River threatened to flood the original townsite, and the federal government — acknowledging its role in necessitating the displacement — funded the relocation of more than 300 buildings to higher ground. Homes, businesses, churches, the post office, even grain elevators were physically moved, relocated, or rebuilt on the new site over the course of 1925 and 1926. It remains the largest government-sponsored town relocation in United States history. The centennial of this remarkable event was celebrated in 2025, with festivities honoring the resilience and community spirit that the relocation demanded. Idaho Code §§ 6-301 et seq. governs all residential tenancies in this remarkable community today.
American Falls Reservoir and the Agricultural Economy
The dam that displaced the original American Falls created something of value in return: a 55,860-acre reservoir that has become one of southeastern Idaho’s most important irrigation and recreational resources. The American Falls Reservoir stores Snake River water that irrigates the surrounding agricultural lands, supporting the production of potatoes, sugar beets, wheat, barley, corn, and oilseeds that form the backbone of Power County’s economy. The reservoir also supports the Snake River’s white sturgeon population — the largest freshwater fish in North America — making American Falls a destination for sturgeon fishing. Boating, waterskiing, and general recreation on the reservoir add a tourism dimension to the county’s economy during summer months.
The Oregon Trail Through Power County
Power County was one of the most significant stretches of the Oregon Trail through Idaho. Massacre Rocks State Park, southwest of American Falls on the Snake River, marks the site of an 1860 attack on a wagon train and preserves the dramatic basalt geology that gave this section of the trail its foreboding name. Register Rock, within the park, is a large basalt boulder inscribed with the names and dates of hundreds of Oregon Trail pioneers who passed between 1841 and 1869 — a tangible archive of the westward migration that is one of the most evocative pioneer heritage sites in the American West. These historic sites draw visitors and contribute to the county’s modest tourism economy.
The Fort Hall Reservation and Power County
Approximately 159,000 acres in eastern Power County fall within the Bannock-Shoshone Fort Hall Indian Reservation, one of the larger reservations in Idaho. The reservation’s tribal government, headquartered in Fort Hall (in adjacent Bingham County), provides employment for tribal members and manages substantial agricultural operations. Landlords managing properties on or near reservation boundaries should be aware that tribal trust land falls under tribal and federal jurisdiction rather than Idaho state law — the Unlawful Detainer process and Idaho Code §§ 6-301 et seq. apply only to non-trust land in Power County. Any property on tribal trust land requires consultation with a licensed attorney with tribal jurisdiction expertise before any landlord action is taken.
