How long does a Idaho landlord have?
Under Idaho Code § 6-321, a Idaho landlord has 21 days (21 days (up to 30 if the lease specifies)) after your tenancy ends to return your deposit or provide an itemized statement of any deductions. Idaho requires that itemized statement when the landlord keeps any part of the deposit. Count from the day the tenancy ended. If the deadline has passed and you haven’t been paid or itemized, your landlord is late — and that’s the leverage your demand letter is built on.
What penalty can a Idaho landlord face?
A landlord who keeps a deposit in bad faith may owe up to 3× the deposit. Specifically, under Idaho Code § 6-321, Idaho law lets a tenant seek up to three times the wrongfully withheld amount if a court finds the landlord acted in bad faith, plus court costs and attorney's fees.
Important: any penalty is something a court may award if it finds the landlord acted in bad faith — it is never automatic, and you would still need to make that case. Idaho also lets a prevailing tenant recover attorney's fees.
How to get your deposit back in Idaho
- 1. Send a written demand. Put the deadline your landlord missed and the statute (Idaho Code § 6-321) in writing, by certified mail with return receipt, so you have proof of the date they received it.
- 2. Keep your records. Move-out photos, the walkthrough checklist, your lease, and proof you gave a forwarding address are your evidence if the landlord disputes the claim.
- 3. If they don’t pay, file in small claims. You can ask a Idaho small claims court to order the deposit returned, and — under Idaho Code § 6-321 — to seek up to three times the wrongfully withheld amount if a court finds the landlord acted in bad faith, plus court costs and attorney's fees plus attorney's fees, which the court may award if you prove your case. The small-claims dollar limit varies by court within the state, so check your county’s limit before filing.
