Idaho landlord guide — Challis (county seat, Salmon River Valley), Stanley (Sawtooth gateway), Frank Church Wilderness (largest in lower 48), Borah Peak & Idaho Code §§ 6-301 et seq.
🏛️ County Seat: Challis (Salmon River Valley) 👥 Population: ~4,275 (2020 census) 🏔 Wilderness: Frank Church — largest in lower 48
Custer County is the geographic heart of Idaho — literally. The center of Idaho’s population has been located in Custer County, near the town of Stanley, for decades. It is also one of Idaho’s most spectacular landscapes: the county’s 4,937 square miles encompass the western slopes of the Lost River Range (home to Borah Peak, Idaho’s highest point at 12,662 feet), the Sawtooth Range along its western border (Thompson Peak, the Sawtooths’ highest summit, rises from Custer County above Redfish Lake), the Salmon River corridor, and the eastern edge of the Frank Church–River of No Return Wilderness — at 2.4 million acres, the largest contiguous wilderness area in the contiguous 48 United States. The county was established in 1881 and named for the General Custer Mine, where gold was discovered five years earlier, shortly after General George Armstrong Custer’s death at the Little Bighorn.
Challis, the county seat, sits at the confluence of the Salmon River and Challis Creek in a wide valley at approximately 5,300 feet elevation. With about 955 residents it is a classic small western county seat: a courthouse, a few blocks of commercial buildings, a school, and a hospital serving a vast rural hinterland of ranching operations and wilderness country. Stanley, at the northern gateway to the Sawtooth National Recreation Area and Sawtooth Wilderness, is a nationally known outdoor recreation destination with a permanent population of a few hundred that swells dramatically in summer with rafters, hikers, anglers, and mountain bikers. The Idaho Cobalt Operations mine near Challis — the only primary cobalt mine in the United States, developed by Jervois Global — began production in 2022 but was idled in 2023 due to market conditions and entered bankruptcy proceedings in early 2025; its long-term future adds economic uncertainty to the county.
All landlord-tenant matters in Custer 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 Custer County District Court (Seventh Judicial District), 801 Main Street, PO Box 385, Challis, ID 83226, (208) 879-2360. Idaho prohibits rent control statewide.

Custer County Local Ordinances & Landlord Rules
Idaho state law governs landlord-tenant matters — no supplemental local ordinances in Custer County
Category
Details
No Local Ordinances
Neither Custer County nor any of its cities — Challis, Stanley, or Clayton — 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 Custer 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 landlord’s right to withhold and exposes the landlord to 3× damages plus attorney fees. Move-in and move-out condition documentation is essential regardless of rent level or community size.
The Stanley Seasonal Market
Stanley is one of the most extreme seasonal rental markets in Idaho. With approximately 35 year-round residents and an influx of thousands of summer visitors, the town’s handful of rental properties serve a dramatically different population in July than in January. Summer demand for housing comes from raft guide companies, USFS recreation staff, Sawtooth NRA employees, fishing guides, and hospitality workers at the lodges and outfitters that serve the Sawtooth Valley’s tourism season. Fixed-term seasonal leases (typically May or June through September) are the appropriate vehicle for this market. Year-round rentals in Stanley face the challenge of extreme winters (Stanley is one of the coldest inhabited places in the contiguous United States, with temperatures routinely dropping to −30°F or below) and very limited winter employment for non-government tenants.
The Cobalt Mine Uncertainty
The Idaho Cobalt Operations mine near Challis, developed by Jervois Global as the only primary cobalt mine in the United States, began production in 2022 and was positioned to capitalize on demand for battery minerals. The mine was idled in 2023 due to depressed cobalt prices and Jervois entered bankruptcy proceedings in early 2025. The mine’s long-term status introduces economic uncertainty that landlords should monitor. If the mine resumes full operations, it could add significant skilled-labor rental demand to the Challis market; if it closes permanently, that demand evaporates. At present, the mine is the county’s largest potential economic variable.
Seismic History
Custer County has experienced two of the largest earthquakes in Idaho history. The 1983 Borah Peak earthquake measured 6.9 on the moment magnitude scale and was the most destructive natural disaster in Idaho in recorded history; it raised Borah Peak by approximately one foot. A 2020 earthquake centered 45 miles west of Challis measured 6.5 and was the second strongest ever recorded in Idaho. Landlords should ensure rental properties are in good structural condition and verify appropriate earthquake-related provisions in their property insurance policies, as seismic risk is a real consideration in this region.

⚠️ 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.

🔍 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.

There is a geographic fact about Custer County, Idaho, that sounds like a trivia answer but is actually just mathematics: the center of Idaho’s population is located in Custer County, near Stanley. Idaho is a long state — 479 miles from north to south — and Custer County sits near the middle of it all, surrounded by some of the most dramatic mountain terrain in the lower 48 states. To the west, the Sawtooth Range rises in a wall of granite spires above the Stanley Basin; Thompson Peak, the tallest at 10,751 feet, stands in Custer County above Redfish Lake, one of Idaho’s most photographed alpine lakes. To the east, the Lost River Range includes Borah Peak at 12,662 feet — Idaho’s highest point and a mountain that grew approximately one foot taller during the 1983 Borah Peak earthquake, a 6.9-magnitude event that caused two deaths, significant property damage, and surface rupture along the Lost River Fault. And to the north and west, the Frank Church–River of No Return Wilderness stretches across 2.4 million acres of virtually roadless canyon and mountain country — the largest contiguous wilderness area in the contiguous United States. Idaho Code §§ 6-301 et seq. governs all residential tenancies here.
Stanley: The Summer Community
Stanley’s permanent population is approximately 35 people, making it one of the smallest incorporated towns in Idaho by year-round population. But from late May through early October, Stanley is transformed into a lively outdoor recreation hub serving thousands of visitors who come for Sawtooth Wilderness hiking, Salmon River whitewater rafting, fly fishing on the legendary Middle Fork of the Salmon, mountain biking, and the spectacular mountain scenery that makes the Sawtooth Valley one of the most photographed landscapes in the American West. Local outfitters, raft companies, lodges, and restaurants hire seasonal staff who need housing during the operating season. USFS and NPS employees at the Sawtooth NRA and Sawtooth National Forest add additional seasonal employment. The result is a rental market that is intense in summer — with very little housing available for a workforce that genuinely needs it — and nearly dormant in winter, when Stanley’s isolation, brutal cold (−30°F temperatures are not uncommon), and limited services make it inhospitable for all but the hardiest year-round residents.
Challis and the Salmon River Valley
Challis sits in a much more livable environment than Stanley — lower in elevation, in a wider valley, with a functional county seat infrastructure. Founded in 1878 and named for surveyor A.P. Challis, it has been a ranching and mining service center for most of its existence. The Salmon River, which flows through the valley on its way to the main Salmon below, provides both agricultural water for hay production and recreational opportunities for anglers and paddlers. The Salmon River Scenic Byway connects Challis to Stanley to the south and to Salmon (in Lemhi County) to the north, serving as both the primary transportation route and an economic artery for tourism. Highway 93 connects Challis eastward over Mackay Summit to Arco and the Snake River Plain. The county’s isolation — Challis is approximately 100 miles from the nearest city of any size — is both its character and its constraint.
The Idaho Cobalt Operations: Promise and Uncertainty
The Idaho Cobalt Operations mine near Challis represented one of the most significant potential economic developments for Custer County in generations. Cobalt — a critical mineral for electric vehicle batteries and other high-tech applications — is mined in very few places in the United States, and the ICO project was positioned as the only primary cobalt mine in the country. Jervois Global, the Australian company that developed the mine, began construction in 2021 and achieved initial production in 2022. The project employed local workers and generated economic activity that benefited Challis businesses and rental property owners during the construction and ramp-up period. But depressed cobalt prices in 2023 led to the mine being idled, and Jervois entered Chapter 11 bankruptcy proceedings in early 2025. The mine remained in care-and-maintenance mode rather than closure, suggesting its owners believe it has long-term value, but its near-term operational status remains uncertain. Landlords who rented to mine workers during the operational period should understand that this employment source could resume, scale up, or disappear entirely depending on commodity markets and the outcome of Jervois’s restructuring.
Filing Evictions in a Remote Mountain County
The Custer County District Court at 801 Main Street in Challis serves the Seventh Judicial District. Main: (208) 879-2360; General: (208) 879-2359. Hours are Monday through Friday, 8:00 a.m. to 5:00 p.m. For nonpayment evictions, the 3-day notice clock starts the day after proper service on the tenant. In a county this remote — where driving from Stanley to the courthouse in Challis takes approximately an hour each way — landlords managing properties in outlying areas should plan the logistics of notice service and court filing carefully. Personal service on the tenant at the rental property, followed by court filing in Challis, requires coordination that takes more time and fuel in Custer County than in most Idaho counties. Written leases, properly served notices, and documented condition records protect landlords here as everywhere else in Idaho.
Custer County landlord-tenant matters 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).

Security deposit: no cap; return within 21 days (up to 30 if lease specifies); 3x penalty for improper handling. No rent control (Idaho Code § 55-304). No local landlord-tenant ordinances. Eviction: Unlawful Detainer at Custer County District Court (7th Judicial District), 801 Main St, PO Box 385, Challis, ID 83226; Main (208) 879-2360; General (208) 879-2359; Mon–Fri 8am–5pm. 72-hour post-judgment vacate; Writ of Possession if tenant remains.
