Idaho Security Deposit Demand Letter — Force Your Landlord to Pay Up

Idaho landlords must refund within 21 days of surrender when no time is fixed by agreement; a lease may set a different period, but never beyond 30 days (Idaho Code § 6-321(2)).

Miss that obligation and the law has teeth: Up to 3x damages (court's discretion). Suit lies under § 6-320(4), and the court may award up to three times actual damages in its discretion under § 6-317, plus costs and attorney's fees.

Your Rights Under Idaho Code § 6-321

Idaho's deposit law is specific. The rights worth knowing before you write:

• The deadline: 21 days (lease max 30). Idaho landlords must refund within 21 days of surrender when no time is fixed by agreement; a lease may set a different period, but never beyond 30 days (Idaho Code § 6-321(2)).
• The penalty: Up to 3x damages (court's discretion). Suit lies under § 6-320(4), and the court may award up to three times actual damages in its discretion under § 6-317, plus costs and attorney's fees.
• Itemization is mandatory. Any partial refund must arrive with a signed statement itemizing the amounts retained, their purpose, and a detailed list of expenditures made from the deposit.
• Worth knowing. No deposit cap in Idaho. Deposits managed by third-party property managers must sit in a separate federally insured account.

What Your Landlord Can — and Can't — Keep

Legitimate deductions

• Unpaid rent you actually owe
• Cleaning needed to return the unit to its condition at move-in (minus ordinary wear)
• Repair of damage beyond normal wear and tear — holes in walls, broken fixtures, pet damage

NOT legitimate deductions

• Normal wear and tear — faded paint, minor scuffs, small nail holes, worn carpet from ordinary use
• Repainting or re-carpeting due simply to age
• Pre-existing damage that was there when you moved in
• Charges with no itemization or receipts where Idaho Code § 6-321 requires them

How to Write an Idaho Security Deposit Demand Letter

An effective letter does four things: states the facts, cites Idaho Code § 6-321 by name, makes a specific dollar demand with a firm deadline, and spells out the consequences if the landlord doesn't comply. Idaho's own courts endorse the demand letter: Ada County's official self-help packet is a § 6-321 demand letter that gives the landlord three days and cites the treble-damages statute. If the property sold mid-tenancy, the new owner inherits the refund duty. Here's how the opening of a strong one reads:

If the Letter Doesn't Work: Idaho Small Claims

Small claims court

Most deposit cases that get this far are filed in small claims court in the county where the rental sits — no attorney required. Bring the lease, move-in/move-out photos, your dated demand letter, and proof of delivery. The demand letter matters in court: it shows the judge you gave the landlord every chance to comply with Idaho Code § 6-321, and it anchors the penalty math — up to 3x damages (court's discretion).

Your county's tenant resources

Many Idaho counties run free tenant help lines, legal-aid clinics, or court self-help centers that will review a deposit case at no charge. Search your county name plus “tenant legal aid” — and bring the same paper trail.

Already hearing from a collection agency?

Landlords hand move-out balances to a small set of specialist collectors. If the letter is from National Credit Systems, Hunter Warfield, IQ Data International, or Source RM, we have a company-specific response guide for each — and the demand letter on this page still applies, because a landlord who missed the statutory deadline may owe you money regardless of who is calling. Any other collector: see the collection agency index and your state’s rules in the debt statute of limitations guide.
