South Dakota Rent Increase Rules: Notice Requirements and Tenant Rights

South Dakota is one of the most landlord-friendly states when it comes to rent increases. There is no rent control, no cap on increase amounts, and no limit on frequency — giving property owners significant flexibility in setting rental rates.

Key Rules at a Glance

Rent Increases During a Fixed-Term Lease

During a fixed-term lease (e.g., a one-year lease), a landlord cannot increase rent unless the lease agreement explicitly contains a provision allowing mid-term increases.

If the lease has no such provision, the landlord must wait until the lease term expires to raise the rent. At renewal, the landlord may propose any new rent amount.

Rent Increases for Month-to-Month Tenancies

For month-to-month tenancies, landlords must provide at least 30 days' written notice before a rent increase takes effect (SDCL §43-32-13).

Tenant's Right to Terminate

If a tenant receives a rent increase notice and does not wish to pay the higher amount, they have the right to terminate the tenancy:

• The tenant must provide the landlord with one month's written notice to terminate a month-to-month tenancy (SDCL §43-32-13).
• There is no special shortened notice period to terminate specifically because of a rent increase.

No Rent Control in South Dakota

South Dakota has no statewide rent control and no local rent control ordinances. This means:

• Landlords can raise rent by any amount
• There is no maximum percentage increase
• No government approval is needed for increases
• Local municipalities cannot enact their own rent control laws

Prohibited Rent Increase Practices

While South Dakota gives landlords wide latitude on rent increases, the following practices are prohibited:

Retaliatory Increases

Under SDCL §43-32-27, landlords may not raise rent in retaliation against a tenant who has:

• Reported code violations or health hazards to government authorities
• Exercised legal rights under the lease or state law
• Organized or joined a tenant organization
• Complained about the landlord's failure to maintain habitable conditions

If a tenant files a complaint and the landlord raises rent within a short time period, the increase may be presumed retaliatory. The burden shifts to the landlord to prove the increase was not retaliatory.

Discriminatory Increases

Under the Fair Housing Act (federal law), landlords may not raise rent based on a tenant's:

• Race, color, or national origin
• Religion
• Sex or gender
• Familial status (having children)
• Disability

South Dakota's state fair housing law also prohibits discrimination based on ancestry.

How to Properly Implement a Rent Increase

Step 1: Review the Lease

• Fixed-term lease — Check if the lease allows mid-term increases; if not, wait until renewal
• Month-to-month — Ensure you provide proper written notice

Step 2: Provide Written Notice

• Deliver at least 30 days before the increase takes effect
• Include the current rent, new rent amount, and effective date
• Use a delivery method that provides proof (certified mail, hand delivery with signature)

Step 3: Document the Reason

While not legally required, documenting the business reason for the increase (rising property taxes, insurance costs, market rates) can help defend against retaliatory increase claims.

Step 4: Allow Tenant Response Period

If the tenant decides not to accept the rent increase, they must provide the standard one month's written notice to terminate the month-to-month tenancy.

Market Context South Dakota's rental market varies by location:

• Sioux Falls — The largest city, with moderate rental growth driven by population increases
• Rapid City — Tourism and military presence (Ellsworth Air Force Base) influence rental demand
• Rural areas — Generally lower rents with smaller annual increases

Understanding local market conditions helps landlords set competitive yet fair rental rates.

Best Practices for Landlords

1. Research market rates — Set increases in line with local comparables to retain good tenants
2. Give more than minimum notice — 60 days notice, while not required, gives tenants time to plan
3. Communicate clearly — Explain the reason for the increase (even though it's not required)
4. Document everything — Keep copies of all notices and delivery receipts
5. Be consistent — Apply the same standards across all units to avoid discrimination claims
6. Consider incremental increases — Small, regular increases are easier for tenants to absorb than large, infrequent ones
