South Dakota imposes no rent control on commercial properties. While SDCL § 6-1-13 prohibits local governments from enacting rent control on private residential property, there is no equivalent statutory prohibition for commercial property; however, no local commercial rent control ordinances currently exist. Rent increases are primarily governed by the specific terms of the lease, which are enforced under the broad contract principles established by SDCL Title 53 and common law.
Key Rules at a Glance
Rent Escalation Structures
Commercial leases in South Dakota typically use one of the following rent escalation structures:
Fixed Annual Increases
The lease specifies a predetermined percentage or dollar increase each year.
CPI-Based Adjustments Rent
is adjusted annually based on the Consumer Price Index (CPI), typically:
- CPI-U (All Urban Consumers) for the region
- With or without a floor (minimum increase) and cap (maximum increase)
- Common structure: CPI with a 2% floor and 5% cap
Market Rate Resets
At renewal or specific intervals, rent is reset to the prevailing market rate:
- Often occurs at the midpoint or renewal of a long-term lease
- May use independent appraisals to determine fair market rent
- Protects the landlord from below-market rates over time
Percentage Lease (Retail)
Common in retail commercial leases, the tenant pays:
- A base rent plus a percentage of gross sales above a breakpoint
- The breakpoint may be adjusted annually
- Particularly common in shopping centers and malls
NNN Escalations (Triple Net)
In triple net leases, the tenant's total cost increases as:
- Property taxes increase
- Insurance premiums rise
- Common area maintenance (CAM) costs change
- These pass-through costs are separate from base rent escalation
Tenancy at Will
For commercial properties operating under a tenancy at will (month-to-month), the landlord may modify the terms of the lease, including rent amounts, by giving written notice at least thirty days before the expiration of the month (SDCL § 43-32-13). Under SDCL § 43-32-13, the tenant has the statutory right to terminate the lease effective the first day of the next month by providing notice of termination to the landlord within fifteen days of receiving the modification notice.
Drafting Effective Rent Escalation Clauses
Essential Elements Every commercial rent escalation clause should include:
- Escalation method — Fixed percentage, CPI, market rate, or hybrid
- Timing — When escalation occurs (annually, at renewal, etc.)
- Calculation details — Specific CPI index, appraisal procedures, or formulas
- Floor and cap — Minimum and maximum increase amounts (if applicable)
- Notice requirements — How and when the tenant will be notified
- Dispute resolution — How disagreements over calculations are resolved
Sample Escalation Language
Fixed Increase:
"Base rent shall increase by three percent (3%) annually on each anniversary of the lease commencement date."
CPI Adjustment:
"Base rent shall be adjusted annually by the percentage change in the CPI-U for the Midwest Region, with a minimum increase of two percent (2%) and a maximum increase of five percent (5%)."
Strategies for Landlords
- Build in escalations from day one — Don't wait for renewal to address rising costs
- Use CPI floors — Ensures you receive at least a minimum increase even in low-inflation years
- Include NNN pass-throughs — Transfer variable costs to tenants to protect margins
- Set market rate reset provisions — For long-term leases, include periodic market adjustments
- Document everything — Keep records of all CPI data, tax assessments, and calculation worksheets
- Communicate increases clearly — Provide written notice with supporting calculations
South Dakota Market Context South
Dakota's commercial rental market varies by region and property type:
- Sioux Falls — Fastest-growing city with strong demand for office, retail, and industrial space
- Rapid City — Tourism and hospitality-driven commercial demand
- Aberdeen/Mitchell/Brookings — Smaller markets with stable, lower rental rates
Understanding local market dynamics helps set appropriate escalation structures that retain quality tenants while protecting investment returns.
