Since Idaho achieved statehood on July 3, 1890, the state's legal framework has evolved to provide property owners with significant flexibility regarding security deposits. While there is no statewide maximum amount, the Idaho Code mandates strict procedures for the handling and return of these funds.
Statutory Limits
Idaho does not set a statutory limit on how much landlords can charge for a security deposit. Property managers and landlords can theoretically set the deposit amount as high as they see fit.
However, standard market practice across Idaho dictates charging the equivalent of one to two months' rent. Charging exorbitant amounts may drive away prospective tenants or raise questions from a judge if the lease terms are ever brought to court.
Holding the Deposit
Unlike some states, Idaho does not require landlords to hold a security deposit in a separate, interest-bearing escrow account unless the property is managed by an independent third-party property management company.
If managed by a third party, funds are generally required to be kept in a federally insured trust account. There is also no requirement for landlords to pay the tenant any interest earned on their security deposit.
Return Deadlines and Procedures
Under Idaho Code § 6-321, a landlord must return the tenant’s security deposit within a strict timeline after the tenant vacates the property:
- Standard Deadline: The deposit must be returned within 21 calendar days of the end of the tenancy.
- Extended Deadline: Landlords can legally extend this return period up to a maximum of 30 days if this extension is expressly agreed upon and stated in the written lease agreement.
Itemized Statement of Deductions
If you choose to withhold any portion of the security deposit, you must provide the former tenant with an itemized statement within the same 21-day (or 30-day) timeframe.
The statement must clearly list:
- The original amount of the deposit
- A detailed description of each deduction
- The specific, actual cost for each item
- The remaining balance being returned to the tenant
Allowable Deductions
Landlords may deduct funds from the security deposit to cover specific costs, but all terms outlining what can be deducted should ideally be detailed in the lease agreement. Common allowable deductions include:
- Unpaid rent
- Repairing damage caused by the tenant, their guests, or pets that exceeds normal wear and tear
- Unpaid utility bills the tenant was liable for
- Cleaning costs required to bring the property back to the condition it was in when the tenant moved in
Normal Wear and Tear vs. Damage
Landlords cannot deduct money for "normal wear and tear." This term generally refers to the expected deterioration of a property from regular, daily living.
Consequences for Non-Compliance
Failure to adhere to Idaho's 21-day or 30-day return rule can result in significant penalties.
If a landlord fails to return the deposit or provide the itemized statement within the required window, they forfeit their right to keep any portion of the deposit. Under Idaho Code § 6-320, a tenant must provide a written 3-day demand notice to the landlord before filing a lawsuit. If the landlord fails to comply within those three days, the tenant may sue in the Magistrate Division (Small Claims Court for claims up to $5,000). If the court finds the landlord acted with malice or intentional non-compliance, the tenant may be awarded three times the amount of the deposit (treble damages), plus court costs and attorney fees.
Best Practices for Idaho Landlords
- Conduct Move-In/Move-Out Inspections: Have the tenant fill out and sign a detailed condition checklist when moving in. Use the same checklist at move-out to easily identify clear damage.
- Explicitly State the 30-Day Limit: If you need more time to assess repairs, ensure your lease explicitly states that you have 30 days to return the deposit; otherwise, you're bound by the 21-day default.
- Take Photos: Keep visual proof of the property's condition before the tenant gets the keys and immediately after they hand them back.
Landager streamlines the moving-out process by allowing you to digitally track security deposits, manage condition reports with photos, and automatically set reminders for the 21-day or 30-day return window. Keeping your accounting organized prevents costly mistakes and disputes with tenants.
