The 5 Most Common Lease Clauses That Fail in South Dakota Courts (And How to Fix Them)

Many property owners rely on standard, online downloadable lease templates or boilerplate documents that haven’t been reviewed by a legal professional familiar with South Dakota real estate law. While these templates might seem sufficient on the surface, vague, overly aggressive, or statutory-conflicting clauses often fail to hold up when challenged in court.

When a dispute escalates to a small claims or magistrate court proceeding, an unenforceable lease clause can result in dismissed claims, lost revenue, or unexpected penalties. Below are five of the most common lease clauses that fail in South Dakota courts—and how to structure them properly.

1. Non-Compliant Security Deposit Return & Forfeiture Clauses

The Common Flaw

Many standard lease templates contain rigid forfeiture language, such as:

Tenant forfeits the entirety of the security deposit if the lease is terminated early for any reason.

Why It Fails in South Dakota

South Dakota Codified Law (§ 43-32-24) strictly governs security deposits. A landlord must return the deposit or provide an itemized written accounting of any withheld funds within 14 days after the tenant surrenders the premises and requests its return (or within 45 days if special circumstances regarding damaged property apply). Automatic total forfeiture clauses without itemized proof of actual damages generally fail under judicial review.

The Fix

Ensure your lease explicitly aligns with South Dakota statutory timelines and clearly defines what qualifies as a legitimate deduction:

• Detail the statutory 14-day window for providing an itemized accounting statement.
• Specify that deductions are strictly limited to unpaid rent, cleaning costs necessary to restore the unit to its initial condition (excluding normal wear and tear), and actual physical damages.

2. Blanket “Right of Entry Without Notice” Clauses

The Common Flaw

Some leases include broad entry provisions intended to give landlords immediate access:

Landlord reserves the right to enter the property at any time without notice for inspections, repairs, or showings.

Why It Fails in South Dakota

While South Dakota law permits landlords to enter leased premises for reasonable inspection, repair, or showing purposes, courts respect the tenant’s implied covenant of quiet enjoyment. Unreasonable or unannounced non-emergency intrusions can lead to tenant claims of constructive eviction or landlord harassment.

The Fix

Draft clear, legally balanced access terms:

• Require a standard 24-hour advance written notice for routine inspections, maintenance, or showings.
• Limit unannounced entry strictly to genuine emergencies (e.g., active water leaks, fire, or immediate structural threats).

3. Vague Maintenance and “Wear vs. Tear” Allocations

The Common Flaw

Leases that try to shift general maintenance obligations onto the tenant often state:

Tenant is responsible for all minor repairs and general maintenance under $200.

Why It Fails in South Dakota

Under SDCL § 43-32-8, the lessor (landlord) has a statutory obligation to maintain the premises in a fitness for human habitation and keep the property in reasonable repair, unless specifically modified by a valid written agreement that doesn’t violate public policy. Broad or ambiguous clauses shifting habitability repairs onto tenants frequently get thrown out, leaving landlords liable for repairs they assumed the tenant would handle.

The Fix

Clearly delineate statutory habitability obligations from tenant operational responsibilities:

• Specify that structural, plumbing, electrical, heating, and habitability repairs remain the landlord’s duty.
• Explicitly outline tenant responsibilities, such as replacing HVAC filters, changing light bulbs, or clearing tenant-caused drain clogs.
• Define “normal wear and tear” versus “tenant-caused damage” with specific examples to avoid ambiguity during move-out audits.

4. Improper Notice Periods for Lease Non-Renewal or Termination

The Common Flaw

Templates drafted for other jurisdictions frequently include arbitrary notice requirements, such as requiring 60 or 90 days’ notice for month-to-month tenancies, or stating that a tenancy automatically terminates without notice.

Why It Fails in South Dakota

South Dakota law (SDCL § 43-32-22) sets specific baseline notice periods for terminating tenancies. For a month-to-month lease, SDCL § 43-32-13 specifies a 30-day written notice requirement. Inserting conflicting or conflictingly calculated deadlines can render a termination notice invalid in court, forcing you to restart the entire notice period.

The Fix

Align all termination and renewal provisions directly with state statutory baselines:

• Ensure month-to-month termination clauses strictly require a minimum 30-day written notice before the end of the rental period.
• Outline clear written notification timelines for fixed-term lease expirations and renewals.

5. Unenforceable Penalty Fees & Accelerated Rent Clauses

The Common Flaw

When a tenant defaults or breaks a lease early, some contracts include extreme penalty provisions:

If Tenant breaches this agreement, all remaining rent for the entire term becomes immediately due as liquidated damages.

Why It Fails in South Dakota

Courts disfavor clauses that function as punitive measures rather than reasonable estimates of actual loss. Landlords in South Dakota generally have a legal duty to exercise reasonable efforts to mitigate damages by attempting to re-rent the property. Demanding full accelerated rent without accounting for re-renting efforts will often be deemed an unenforceable penalty.

The Fix

Structure default remedies around actual damages and legitimate administrative costs:

• Include reasonable, legally defensible late fee structures.
• Clause early termination remedies around actual costs incurred (e.g., re-letting expenses, lost rent during turnover) while maintaining active mitigation practices.

Summary & Key Takeaways

A single poorly worded clause can compromise an entire lease agreement during a dispute. To protect your rental assets and maintain smooth operations:

• Avoid generic online templates that fail to account for South Dakota statutory requirements.
• Review your lease terms regularly to ensure compliance with state laws and local regulations.
• Ensure clear, specific language around notice periods, deposit returns, and repair duties.
