South Dakota Commercial Late Fees: Rules, Structures, and Enforcement

Commercial late fees in South Dakota are governed almost entirely by the lease agreement, with minimal statutory restrictions. This gives landlords significant flexibility in structuring payment enforcement but requires careful drafting to ensure enforceability.

Key Rules at a Glance

No Statutory Cap on Commercial Late Fees

South Dakota does not impose a specific cap on late fees for commercial leases. However:

• Fees must be documented in the lease agreement
• Fees should be commercially reasonable — grossly excessive fees could be challenged
• Courts are generally more deferential to commercial lease terms than residential ones

Common Fee Structures

Flat Fee

A fixed dollar amount charged when rent is late:

Percentage-Based Fee

A percentage of the monthly rent:

• 5% — Conservative but common
• 10% — Higher end, generally still enforceable for commercial
• 15%+ — May face scrutiny but less likely to be challenged in commercial context

Daily Penalties

A per-day charge that accrues until payment is received:

• Common range: $25–$100/day depending on rent amount
• Should include a maximum cap to avoid unconscionability
• Example: "$50/day up to a maximum of $1,500"

Interest on Late Payments

An annual interest rate applied to unpaid balances:

• South Dakota legal interest rate: 15% per annum on contract obligations (SDCL §54-3-16) unless a different rate is specified in the lease
• Common lease provisions: 1%–1.5% per month (12%–18% annually)
• Must be specified in the lease to be enforceable

Structuring Your Late Fee Policy

Step 1: Define the Due Date

Specify exactly when rent is due:

• "Rent is due on the first (1st) day of each calendar month"
• Include what happens if the due date falls on a weekend or holiday

Step 2: Set a Grace Period (Optional)

While not required, many commercial leases include a grace period:

Step 3: Choose a Fee Structure

Select one or combine multiple approaches:

• Flat fee for initial late payment
• Daily penalty if payment is significantly delayed
• Interest on the outstanding balance
• Acceleration clause — making all remaining rent due upon default

Step 4: Define Escalation

Specify what happens if late payment becomes chronic:

Additional Payment Enforcement Tools

NSF (Returned Check) Fees

• Statutory limit: $30–$40 per returned check
• Specify in the lease
• Consider requiring electronic payment after repeated NSF incidents

Acceleration Clause

An acceleration clause makes all remaining rent for the lease term immediately due upon tenant default:

• Must be clearly stated in the lease
• Consult an attorney to ensure enforceability
• Courts may evaluate reasonableness in extreme cases

Personal Guaranty For small business tenants:

• Require a personal guaranty from business owners
• Provides recourse beyond the business entity
• Strengthens landlord's position in collection

Security Deposit Application

The lease should specify:

• Whether the landlord can apply the security deposit to late rent
• Whether the tenant must replenish the deposit after application
• The order of application (late fees first, then rent, or vice versa)

Enforcement Best Practices

1. Document everything in the lease — Specific amounts, grace periods, and escalation procedures
2. Apply fees consistently — Treat all tenants equally to avoid claims of discrimination
3. Send formal notices — Use written notices for all late payment communications
4. Track payments meticulously — Maintain detailed records of all amounts owed and received
5. Act promptly — Don't let arrears accumulate before taking action
6. Communicate before enforcing — A courtesy call before imposing fees can preserve relationships
7. Reserve the right to waive — Include language allowing you to waive fees without creating precedent
8. Coordinate with legal counsel — For chronic late payers or significant amounts

Legal Considerations

Enforceability For commercial late fees to be enforceable in South Dakota:

• They must be documented in the lease
• They should be reasonable relative to the landlord's actual damages
• They should not be so excessive as to constitute a penalty
• The tenant must have agreed to the terms in the lease

Relationship to Eviction

Charging late fees does not prevent the landlord from also pursuing eviction. Similarly, accepting late fees does not waive the landlord's right to evict for chronic non-payment.
