✓ Law Verified June 2026

This guide explains idaho security deposit law in plain English — how much your landlord can charge, when they must return it, what they can and cannot deduct, and what to do if they do not give it back. All figures are from Idaho law, verified as of June 2026.

Idaho Security Deposit Rules at a Glance

Maximum deposit No statutory limit. Idaho law does not cap how much a landlord may charge as a security deposit. In practice most landlords charge 1-2 months’ rent, but there is no legal maximum.
Return deadline 21 days after the tenant surrenders the premises if no time is fixed by the rental agreement. If the written lease specifies a longer period, the deadline may be extended but cannot exceed 30 days.
Itemized deductions required YES. The landlord must deliver a written itemized accounting of all deductions, including the specific reason for each charge and the dollar amount, along with any remaining refund balance. This statement must be provided within the return deadline (21 or 30 days).
Interest on deposit required NO. Idaho does not require landlords to pay interest on security deposits to tenants. However, if the deposit is managed by a third party (such as a property management company), the funds must be placed in a separate federally insured interest-bearing account — but the interest is not required to be paid to the tenant.
Penalty for late/bad-faith return If the landlord fails to return the deposit or provide the required written itemized statement within the 21-day (or lease-specified up to 30-day) deadline, the landlord forfeits the right to withhold any portion of the deposit. The tenant may then sue, and the court may award the tenant up to 3 times the amount of the security deposit in damages under Idaho Code § 6-321.

Move-in/move-out walkthrough: Idaho law does not require a formal move-in or move-out walkthrough inspection. However, it is strongly recommended that tenants document the condition of the unit with dated photos and video at both move-in and move-out. A written condition checklist signed by both parties at move-in is a best practice that many tenants can use to protect their deposit.

Separate deposit account: Not required for owner-managed properties. However, if the security deposit is managed by a third party (such as a property management company), Idaho Code § 6-321 requires the deposit to be placed in a separate, federally insured interest-bearing account.

What Your Landlord Can and Cannot Deduct in Idaho

A landlord may deduct for (1) unpaid rent or other charges owed under the lease, (2) the cost of repairing damage caused by the tenant, the tenant’s household members, or their guests that goes beyond normal wear and tear, and (3) cleaning costs necessary to restore the unit to the condition it was in at the start of the tenancy. The landlord may not deduct for normal wear and tear.

Normal wear and tear vs damage: Idaho Code § 6-321 defines normal wear and tear as “that deterioration which occurs based upon the use for which the rental unit is intended and without negligence, carelessness, accident, or misuse or abuse of the premises or contents by the tenant or members of his household, or their invitees or guests.” Examples include minor scuffs on walls, slight carpet wear in traffic areas, and small nail holes from hanging pictures.

Damage from negligence, misuse, or abuse is NOT normal wear and tear.

How to Get Your Deposit Back in Idaho

(1) Send a written demand letter to the landlord requesting the return of the deposit, citing Idaho Code § 6-321 and the applicable deadline. Keep a copy. (2) If the landlord does not respond or refuses, you may file a claim in Idaho small claims court (called the Small Claims Department of the Magistrate Division), which handles disputes up to 5000.

No attorney is needed. (3) You may be awarded up to 3 times the deposit if the court finds the landlord failed to comply with the law. (4) You may also contact Idaho Legal Aid Services for free assistance. The Idaho courts self-help guide at courtselfhelp.idaho.gov provides forms and instructions.

Other Idaho deposit rules: (1) If the tenant abandons the property (leaves without notice or surrendering the premises), the landlord may apply the deposit to any damages and unpaid rent without following the standard return timeline, but must still provide an itemized statement if the tenant requests one.

(2) The 21-day default return period only applies when no timeframe is specified in a written agreement — tenants should check their lease for the exact deadline, which may be up to 30 days.

(3) Idaho has no statewide rent control, so security deposit amounts are entirely market-driven and negotiable. (4) Third-party property managers are held to a stricter standard and must use a separate federally insured interest-bearing account for deposits.
