Security Deposit Limits in Idaho: What Tenants Need to Know

In Idaho, there is no state-mandated limit on the amount a landlord can charge for a security deposit. While many landlords traditionally request the equivalent of one to two months' rent, owners have the legal flexibility to set deposit amounts based on rental criteria and risk assessment.

Updated with grounded research as of 2026-10-12.

The short answer

Yes, an Idaho landlord can legally charge more than one month's rent for a security deposit because state law does not impose a maximum cap on these fees.

Key facts

No Statutory Cap
Idaho Code § 6-321 does not restrict the amount a landlord may require as a security deposit.
Market Custom
Although not legally mandated, it is common industry practice in Idaho for landlords to charge between one and two months' rent.

Understanding Idaho's Security Deposit Regulations

In Idaho, security deposit amounts are generally determined by the landlord rather than by state statutes. Because there is no statutory limit, landlords have the authority to set deposit amounts that align with their specific risk assessment policies, such as credit history, rental references, or property features.

Common Practices and Expectations

While the law provides flexibility, most rental agreements in Idaho follow established market norms. Tenants should expect the following:

Common Practice: Many property managers and private landlords request an amount equivalent to one to two months' rent.

Negotiation: Because the law does not set a cap, the security deposit amount is often a negotiable item during the lease application process.

Documentation: Regardless of the amount, always ensure the security deposit terms, including the conditions for full or partial refunds, are clearly outlined in your written lease agreement.

Additional Considerations for Tenants

Beyond the initial deposit amount, tenants should remain aware of their rights and responsibilities throughout the tenancy.

Move-in/Move-out Inspections: Document the condition of the property thoroughly upon arrival to ensure deposit deductions reflect actual damages beyond normal wear and tear.

Statutory Protections: While the *amount* of the deposit is unregulated, the *handling* of the deposit—including return timelines and allowable deductions—is governed by Idaho law.

Common questions

Can a landlord charge different security deposit amounts for different tenants?

Yes, landlords may generally set different deposit amounts based on legitimate, non-discriminatory criteria such as rental history, credit scores, or pet ownership, provided they comply with Fair Housing laws.

Does Idaho law differentiate between pet deposits and security deposits?

Idaho statutes do not specifically distinguish between these terms. Any money paid upfront to cover potential damages or lease violations is generally treated as a security deposit under Idaho Code § 6-321.
