Idaho (ID) law guide

The state has explicitly banned local rent control ordinances through statute, leaving pricing entirely to market forces across its fast-growing rental metros.

Boise's rapid population growth through 2021-2023 pushed 2-bedroom rents past $1,600 at their peak; as the market softened in 2024-2025, Idaho's landlord-friendly deposit and eviction rules have kept institutional investment flowing into the Treasure Valley while tenants enjoy comparatively few statutory protections.
Idaho Code § 6-321 governs security deposits but sets no maximum deposit amount, meaning landlords may collect whatever sum the rental market will bear. In practice, most landlords in Boise and the Treasure Valley collect one to two months' rent, though there is nothing in state law to prevent a higher figure for furnished units or tenants with weak credit histories. Landlords must hold residential security deposits in a separate federally insured account, and if the property is sold or changes management, the new owner or manager assumes full liability for those funds.
After a tenant surrenders the premises, landlords have 21 days to return the deposit if the lease is silent on the timeline, or up to 30 days if the written lease specifies that longer period. Whichever deadline applies, any amount withheld must be accompanied by a signed, itemized statement explaining every deduction, listing actual expenditures or estimated repair costs. Idaho law is explicit that landlords cannot retain any portion of a deposit to cover normal wear and tear, defined as deterioration resulting from intended use without negligence, carelessness, or misuse by the tenant.
Landlords who miss the return deadline or fail to supply an adequate itemization lose the right to keep any part of the deposit. A tenant may sue in small claims or district court to recover the withheld amount, and courts may award attorney fees to a prevailing tenant. These rules put the documentation burden squarely on the landlord, making thorough move-in and move-out inspection reports a practical necessity rather than a formality.
Idaho has no statewide rent control, and the legislature has gone further by expressly prohibiting cities and counties from enacting any local rent stabilization ordinance. This preemption means no municipality in the state, including Boise, can cap annual increases or require just-cause justification for raising rent. Landlords may raise rent by any amount at any time, subject only to the notice requirements set out in Idaho Code § 55-307.
For residential month-to-month tenancies, landlords must deliver written notice of a rent increase at least 30 days before the new rent takes effect. The general provision of § 55-307 allows lease term changes on 15 days' notice, but for residential rentals the 30-day requirement governs. If the property is rented under a fixed-term lease, the rent cannot be raised during the lease term unless the agreement expressly permits mid-term increases.
Because Idaho places no ceiling on the size of a rent increase, tenants on month-to-month agreements face meaningful market exposure in high-demand corridors like Meridian, Eagle, and Coeur d'Alene. The sole statutory guardrails are the anti-retaliation and anti-discrimination provisions: a landlord may not raise rent in response to a tenant's good-faith habitability complaint (Idaho Code § 6-320(3)), and any increase must be applied uniformly without regard to protected class characteristics under state and federal fair housing law.
Idaho's eviction framework is among the fastest in the country for landlords pursuing nonpayment cases. Under Idaho Code § 6-303(2), when a tenant fails to pay rent on time the landlord must first serve a written 3-day notice to pay rent or vacate before filing an unlawful detainer action in court. The notice must state the exact amount owed and the date by which payment or possession must be returned. If the tenant pays in full within three days, the eviction stops. If not, the landlord may file immediately with the magistrate or district court.
For lease violations other than nonpayment, a 3-day notice to cure or quit is also required, giving the tenant three days to remedy the breach. Terminating a month-to-month tenancy for reasons other than cause requires a 30-day written notice under Idaho's civil code provisions. Once a landlord files an unlawful detainer complaint and the tenant is served, a hearing is typically scheduled within a matter of days to a few weeks, making Idaho's total eviction timeline relatively short compared to states with longer statutory waiting periods.
Self-help eviction is strictly prohibited in Idaho regardless of how egregious the tenant's conduct. A landlord who changes the locks, removes doors or windows, shuts off utilities, or otherwise forces a tenant out without a court order may face liability for actual damages, statutory penalties, and attorney fees under Idaho Code § 6-324. Every eviction, regardless of circumstances, must proceed through the formal unlawful detainer court process.
Idaho recognizes an implied warranty of habitability, requiring landlords to maintain residential units in a condition fit for human occupation throughout the tenancy. This means functioning heat, plumbing, electrical systems, and weatherproofing must be kept in working order. When a landlord receives written notice of a serious habitability defect, repairs should be completed within a reasonable time, and courts have recognized as few as three days as reasonable for urgent conditions. Tenants may pursue damages and other remedies under Idaho Code § 6-320 if landlords fail to act.
Tenants are also protected from retaliatory conduct by Idaho Code § 6-320(3). If a tenant makes a good-faith complaint to the landlord or a housing authority about unsafe conditions, code violations, or habitability problems, the landlord may not respond by raising rent, reducing services, refusing to renew the lease, or initiating eviction. A court may presume retaliation if adverse action follows within a close time frame of the complaint, shifting the burden to the landlord to prove a legitimate, non-retaliatory reason for the action.
Idaho law requires landlords to give reasonable notice before entry, typically 24 hours, except in genuine emergencies. Tenants have the right to quiet enjoyment of the premises and may contest an unlawful detainer action in court, raise habitability as a defense, and request a jury trial if the amount at issue qualifies. Boise has published a local Notice of Tenant Rights and Responsibilities that supplements state law with additional guidance, though it does not override or expand on the state statutory framework.

Idaho FAQ
Idaho law sets no maximum security deposit amount. Landlords may charge whatever sum they choose, though one to two months' rent is most common in Boise and other Treasure Valley markets. The deposit must be held in a separate federally insured bank account.
If the lease does not specify a timeframe, the landlord has 21 days after the tenant surrenders the unit. A written lease may extend that deadline up to 30 days. Any amount withheld must be accompanied by a signed itemized statement; missing the deadline forfeits the landlord's right to keep any portion of the deposit.
Yes. Idaho has no rent control and has banned cities and counties from enacting local rent caps. A landlord may raise rent by any dollar amount, but must give at least 30 days' written notice before the increase takes effect on a residential month-to-month tenancy.
Under Idaho Code § 6-303(2), a landlord must serve a written 3-day notice to pay rent or vacate before filing an eviction lawsuit. If the tenant pays the full amount owed within three days, the eviction process stops. If they do not, the landlord may file an unlawful detainer action in court immediately.
No. Self-help eviction - including changing locks, removing doors, or shutting off utilities to force a tenant out - is illegal in Idaho. A landlord who attempts this may be liable for the tenant's actual damages, penalties, and attorney fees under Idaho Code § 6-324. All evictions must go through the court process.
Yes. Idaho Code § 6-320(3) prohibits landlords from evicting a tenant, raising rent, reducing services, or refusing to renew a lease in retaliation for a good-faith habitability complaint or report to a housing authority. Courts may presume retaliation when adverse action closely follows a tenant complaint.
