Idaho security deposit law
Short answer: An Idaho landlord must refund the deposit within 21 days after the tenant moves out, or up to 30 days if the lease sets a longer time. Any partial refund needs a signed, itemized statement. State law sets no limit on the deposit amount.
| Deadline to return the deposit | 21 days after the tenant moves out, unless the lease sets a different time. In no case later than 30 days. |
|---|---|
| Limit on how much a landlord can charge | No limit in state law. |
| Itemized list of deductions | Yes. A partial refund must come with a signed statement itemizing each amount kept, its purpose, and a detailed list of what the money was spent on. |
| Interest on the deposit | Not required by state law. |
| Penalty if the landlord breaks the rules | Idaho's deposit section doesn't set a multiplied penalty. A tenant can sue for the money, and the winner of a landlord-tenant lawsuit under this chapter is entitled to attorney's fees. |

Good to know
- Normal wear and tear can't be deducted.
- If the property is sold during the tenancy, the new owner is responsible for refunding the deposit.
- Deposits held by a third-party property manager must be kept in a separate account at a federally insured bank.
Tips for landlords
- Do a written move-in inspection and have the tenant sign it. Take dated photos of every room, including inside appliances and closets.
- Collect the tenant's forwarding address in writing at move-out.
- Put the itemized list and the refund in the mail well before the deadline, and keep proof of mailing.
- Normal wear and tear (faded paint, light carpet wear, small nail holes) usually can't be charged. Damage beyond that can.
Tips for tenants
- Take your own dated photos and video on move-in day and move-out day.
- Give your landlord your forwarding address in writing, and keep a copy.
- If the deadline passes, send a written demand letter that cites the law above before going to small claims court.
