Idaho Security Deposit Return Requirements

Under Idaho Code § 6-321, landlords must return security deposits within 21 days of tenancy termination and surrender of the premises, or up to 30 days if specified in a written lease agreement. If deductions are made, landlords must issue a signed, itemized statement outlining the deductions and actual expenditures. Landlords cannot deduct for normal wear and tear.

The short answer

In Idaho, landlord-tenant security deposit returns are strictly regulated under Idaho Code § 6-321. Landlords are required to return a tenant's full security deposit within 21 days after lease termination and surrender of the premises, unless a longer timeline of up to 30 days is explicitly written into the lease agreement. If any portion of the deposit is withheld, the landlord must provide a signed, itemized written statement detailing the deductions, reasons, and actual expenditures. Withholding funds for normal wear and tear is illegal under Idaho law.

Key facts

Standard Statutory Return Window
21 days after surrender of the premises if no timeline is specified, or up to a maximum of 30 days if fixed by a written lease agreement in Idaho [1.1.1].
Itemized Deduction Statement
Any refund less than the full deposit must include a signed written statement detailing itemized deductions, reasons for retention, and actual expenditures made.
Prohibited Deductions
Landlords are prohibited under Idaho Code § 6-321 from retaining any portion of a security deposit for normal wear and tear.
Third-Party Property Manager Account Requirements
Security deposits managed by a third-party property manager in Idaho must be held in a separate account at a federally insured financial institution, kept distinct from operating funds.

Statutory Timelines and Deposit Disposition Rules

Idaho law provides a strict timetable for security deposit refunds once a tenancy ends and possession of the unit is surrendered [1.1.1]. The default statutory requirement gives landlords 21 days from surrender to process the refund or provide a deduction accounting. However, if both parties agree to a longer timeframe in a written rental agreement, that window can extend up to a maximum of 30 days.

  • Default Deadline: 21 days from physical surrender of the unit if the lease is silent [1.1.1].
  • Extended Lease Deadline: Up to 30 days if explicitly stated in the written rental agreement.
  • Ownership Transfer: If a property changes ownership during tenancy, the new owner assumes legal responsibility for deposit refunds under Idaho Code § 6-321(3).

Allowable Deductions and Normal Wear and Tear Standards

When returning less than the total deposit, an Idaho landlord must provide a signed statement itemizing all lawful deductions, the reasons for retention, and a breakdown of actual expenditures [1.1.1]. Landlords can deduct for tenant damage, lease-specified charges, or unpaid rent, but state law strictly forbids deductions for normal wear and tear.

  • Definition of Wear and Tear: Deterioration that occurs from normal intended use without negligence, carelessness, accident, misuse, or abuse [1.1.1].
  • Permissible Uses: Unpaid rent, property damage beyond normal wear, or specific unpaid tenant obligations outlined in the lease.
  • Required Documentation: Itemized statement with receipted expenses or explicit lists of actual expenditures.

Trust Account Mandates and Statutory Remedies

  • Third-Party Trust Accounts: Must be kept at a federally insured bank separate from operating capital (Idaho Code § 6-321(4)) [1.1.1].
  • Tenants' Legal Recourse: Tenants can issue a formal 3-day demand letter under Idaho Code § 6-320 before initiating suit for wrongful withholding.

Common questions

Can an Idaho landlord charge more than one month's rent for a security deposit?

Yes. Idaho law does not set a statutory cap on the maximum initial security deposit a landlord can require [1.1.3]. Deposit amounts are governed by the terms of the lease agreement negotiated between landlord and tenant.

What happens if an Idaho landlord misses the 21 or 30-day security deposit deadline?

If a landlord fails to provide the refund or itemized statement within the statutory timeframe (21 days default, or up to 30 days by written contract), they forfeit the right to withhold funds and can face legal action under Idaho Code § 6-320.
