Idaho Security Deposit Return Letter

When a tenancy ends, an Idaho landlord has a set time to return the deposit or send an itemized list of deductions. Here’s what Idaho’s statute says.

Security deposits in Idaho

Idaho sets no limit on the size of a security deposit. Any amount a tenant pays for a purpose other than rent is treated as a security deposit, and the statute controls how and when it comes back (§6-321(1)).

  • Wear and tear — The landlord can’t keep any part of the deposit for normal wear and tear — deterioration from ordinary intended use, without negligence, carelessness, accident or abuse by the tenant, household or guests (§6-321(1)).
  • Refund deadline — Refunds are due within 21 days after the tenant surrenders the premises if the lease fixes no period, and in any event within 30 days. The lease can set its own period, but never more than 30 days (§6-321(2)).
  • Itemized statement — Any partial refund must come with a signed statement itemizing what was kept, why, and a detailed list of what was spent from the deposit (§6-321(2)).
  • Sale of the property — If the property changes hands during the tenancy, the new owner becomes liable to refund the deposit (§6-321(3)).
  • Third-party managers — A deposit held by a third-party property manager (other than a real estate licensee and certain affiliated or nonprofit managers) must be kept in a separate federally insured account, apart from the manager’s operating funds (§6-321(4)).
  • Tenant remedy — Failure to return a deposit as required is grounds for a tenant lawsuit after a 3-day written demand (§6-320(a)(4), (d)).

Tenant protections you can’t waive

  • Deposit rules — The 21/30-day refund deadline, the itemized statement and the ban on charging normal wear and tear apply regardless of the lease (§6-321).
  • Fee limits — Fees must be reasonable and agreed in writing, and changing them on a written lease needs 30 days’ written notice (§55-305).
  • Notice of increases — The 30-day written notice for a rent increase or non-renewal applies to all residential leases (§55-304(2)).
  • Court process — The legal route to recover possession is an unlawful-detainer action under Idaho Code Title 6, chapter 3. Idaho has no specific lockout statute, but self-help such as changing locks or cutting utilities to force a tenant out exposes the landlord to liability.

Idaho Security Deposit Return Letter FAQs

How much can a landlord charge for a security deposit in Idaho?

Idaho has no statutory cap — the deposit is whatever the lease sets. The law instead controls the refund: no deductions for normal wear and tear, and a refund within 21 to 30 days with an itemized statement (Idaho Code §6-321).

How long does a landlord have to return a security deposit in Idaho?

Within 21 days after the tenant moves out if the lease doesn’t set a period, and never more than 30 days. Any deductions must be itemized in a signed statement with a detailed list of expenditures (§6-321(2)).
