Commercial vs. Residential Deposit Rules

Deposit Amounts

South Dakota law imposes no statutory cap on commercial security deposits. The deposit amount is determined by negotiation between landlord and tenant, typically based on:

• Creditworthiness of the tenant business
• Lease term — longer leases may warrant higher deposits
• Tenant improvements — if the landlord is investing in buildout
• Type of business — higher-risk operations may justify larger deposits
• Monthly rent — common to collect 2–6 months' rent as deposit

Common Deposit Structures

Return Deadline: 60 Days

Under SDCL §43-32-6.2, upon termination of the tenancy and receipt of the tenant's mailing address or delivery instructions, the landlord must return the commercial security deposit within 60 days.

Itemized Accounting: 90 Days

If the tenant requests an itemized accounting of any amounts withheld, the landlord must provide it within 90 days after the tenancy ends.

Allowable Deductions

Landlords may withhold amounts from the commercial security deposit for:

1. Tenant defaults in rent — Unpaid rent or other agreed-upon charges
2. Restoration costs — Expenses to restore the premises to their condition at the start of the tenancy
3. Beyond ordinary wear and tear — Damage caused by the tenant that exceeds normal deterioration

NOT Deductible

• Ordinary wear and tear — Normal deterioration from everyday commercial use
• Pre-existing conditions — Damage that existed before the tenant took possession
• Landlord improvements — Upgrades unrelated to tenant damage

Penalties for Non-Compliance

If a landlord fails to comply with the commercial security deposit return requirements:

• The landlord forfeits all rights to withhold any portion of the deposit
• The tenant may pursue the full deposit amount in court
• Courts may award additional damages and court costs

Best Practices for Landlords

1. Document the deposit in the lease — Specify the amount, conditions, and return procedures
2. Conduct property inspections — Document conditions at move-in and move-out with photos and checklists
3. Track return deadlines — Set calendar reminders for the 60-day and 90-day deadlines
4. Keep detailed records — Maintain receipts for any repairs or restoration work
5. Communicate early — If deductions will be made, inform the tenant as soon as possible
6. Consider alternatives — Letters of credit or personal guaranties may be more appropriate for large tenants
