Key Commercial Lease Rules at a Glance

Security Deposits

Commercial security deposits in South Dakota have no statutory cap, unlike residential deposits which are limited to one month's rent. Landlords have broad discretion in determining deposit amounts, often based on the tenant's creditworthiness, lease duration, and property type.

Key differences from residential deposits:

• Return deadline: 60 days (vs. 14 days residential)
• Itemized accounting: 90 days if requested by tenant (vs. 45 days residential)
• No cap: Landlord determines the amount based on lease negotiations

For more detail, see our Commercial Security Deposits guide.

Eviction Process

Commercial evictions in South Dakota follow a structured legal process but generally offer landlords more flexibility than residential evictions:

• Nonpayment of rent: 3-day notice to quit
• Lease violations: 10-day notice to cure
• General breaches: 20 business days' written notice
• Tenancy at will: 1 month's notice to terminate

Self-help evictions (changing locks, removing property) are prohibited even for commercial properties.

For more detail, see our Commercial Eviction Process guide.

Lease Requirements

Commercial leases in South Dakota are highly flexible and primarily governed by the agreement between the parties. Common lease types include:

• Gross lease — Landlord covers all operating expenses
• Net lease — Tenant pays some or all operating expenses
• NNN (Triple Net) lease — Tenant pays property taxes, insurance, and maintenance
• Percentage lease — Common in retail; tenant pays base rent plus a percentage of sales

For more detail, see our Commercial Lease Requirements guide.

Rent Increases

As with residential properties, South Dakota imposes no rent control on commercial leases. Rent increase terms are governed entirely by the lease agreement. Common approaches include:

• Fixed annual increases (e.g., 3% per year)
• CPI-based adjustments
• Market rate resets at lease renewal
• Percentage lease adjustments tied to sales

For more detail, see our Commercial Rent Increases guide.

Required Disclosures

Commercial landlords have fewer mandatory disclosure requirements than residential landlords. Key disclosures include:

• Environmental contamination — Including methamphetamine and hazardous materials
• Property conditions — Material defects that affect the tenant's use
• Zoning and use restrictions — Any limitations on permitted business activities

For more detail, see our Commercial Required Disclosures guide.

Maintenance Obligations

Maintenance responsibilities in commercial leases are typically negotiable and defined by the lease agreement, unlike residential leases where the implied warranty of habitability applies. Common arrangements include:

• Landlord responsible — Structural elements, roof, exterior walls
• Tenant responsible — Interior maintenance, HVAC, tenant improvements
• NNN leases — Tenant assumes most or all maintenance obligations

For more detail, see our Commercial Maintenance Obligations guide.

Late Fees

Late fees for commercial leases in South Dakota are governed by the lease agreement. There is no statutory cap, and the terms are highly negotiable.
