South Dakota Landlord-Tenant Laws (2026): Deposits, Notice, and Tenant Rights

South Dakota limits security deposits to one month's rent (two months if you have a pet), requires landlords to return the deposit within 14 days when no deductions are claimed or within 45 days with an itemized list, and mandates 24 hours written notice before entry.

Security deposits in South Dakota

South Dakota law caps residential security deposits at one month's rent for most tenancies. If you have a pet, the landlord may collect up to two months' rent as a deposit. These limits apply to the total deposit collected before move-in; a landlord cannot lawfully require more.

When the tenancy ends, the landlord has two tracks for returning the deposit. If there are no deductions, the full amount must be returned within 14 days of the tenant vacating and surrendering the keys. If the landlord intends to make deductions for unpaid rent, damage beyond normal wear and tear, or other permitted charges, South Dakota law allows up to 45 days to provide a written itemized statement along with any remaining balance.

Rule	South Dakota
Standard cap	1 month's rent
Cap with pet	2 months' rent
Return (no deductions)	14 days
Return (with deductions)	45 days + itemized list

Failing to return the deposit or provide the itemized statement within the applicable deadline can expose a landlord to a damages claim in small claims court. Keep your forwarding address in writing so the clock starts clearly.

When can a landlord enter? Notice rules

Under South Dakota law, a landlord must give a tenant at least 24 hours written notice before entering the rental unit. The notice must specify the date, the approximate time, and the reason for entry. This applies to routine inspections, maintenance visits, showings to prospective tenants or buyers, and any other non-emergency purpose.

Emergency entry (for example, a burst pipe or fire) is permitted without advance notice when the situation requires immediate action to prevent serious damage or injury. Outside of genuine emergencies, a landlord who enters without proper notice may be liable for harassment or breach of the tenant's right to quiet enjoyment.

Tenants can agree to a shorter notice period for a specific visit, but cannot waive the right to notice in a blanket lease clause. Entry should happen during reasonable daytime or business hours absent a different agreement or genuine emergency.

Ending a lease: notice to vacate

For a month-to-month rental in South Dakota, either the landlord or the tenant may end the tenancy by giving 30 days written notice (one full rental period). The notice should be delivered before the start of the rental period it is meant to terminate, so if rent is due on the first of the month, notice should be served no later than the first to end the tenancy effective the last day of that month.

Fixed-term leases generally expire by their own terms, but a landlord who wants to end the tenancy early for nonpayment, lease violation, or other cause must follow South Dakota's eviction procedures. See the South Dakota eviction notice page for the specific notice types (3-day pay-or-quit, 3-day cure-or-quit) and the court process. Month-to-month notice and eviction-cause notice are two entirely different procedures; one is not a substitute for the other.

Repairs and the warranty of habitability

South Dakota requires landlords to deliver and maintain rental housing that is safe and sanitary. SDCL 43-32-8 sets out the landlord's duties: keeping the premises in a condition fit for human habitation, maintaining heating, plumbing, and electrical systems in good repair, and addressing conditions that endanger health or safety.

South Dakota does not have an explicit statutory repair-and-deduct remedy the way some states do. That means a tenant who needs a serious repair generally cannot simply hire a contractor and subtract the cost from rent without risking an eviction for nonpayment. Instead, the practical remedies available in South Dakota are to document the problem in writing, send formal notice to the landlord, pursue a habitability claim in small claims or circuit court, or in extreme cases treat a landlord's total failure to maintain habitable conditions as a constructive eviction and terminate the tenancy.

Tenants should document all repair requests in writing (text or email with a read receipt works) and keep copies. A paper trail is essential if you ever need to pursue a court claim or deposit dispute.

Rent, late fees, and rent control

South Dakota does not cap late fees by statute. Whatever the lease says about a grace period and fee amount governs, provided it is not unconscionable. Many landlords provide a 3 to 5 day grace period before charging a late fee; the lease controls, so read it carefully before signing.

Landlords must give reasonable notice before raising rent on a month-to-month tenant, which in practice means notice equal to the rental period (30 days). For a fixed-term lease, rent cannot be raised during the term; any increase takes effect at renewal.

South Dakota does not permit rent control. State law preempts any local ordinance that would cap, freeze, or otherwise regulate rent amounts. No city or county in South Dakota may enact rent control, and there is no statewide rent cap. Landlords may raise rent to market rate at each lease renewal.

If you have a landlord-tenant dispute in South Dakota

Start by putting everything in writing. Send repair requests, complaints, and notices by email or certified mail so you have a timestamp and delivery record. Courts weight written evidence heavily in landlord-tenant disputes.

For unpaid deposit disputes involving amounts under $12,000, small claims court (called Magistrate Court in South Dakota) is often the fastest and cheapest forum. Filing fees are modest, lawyers are optional, and judges are familiar with deposit return rules.

If the dispute involves habitability, discrimination, or complex lease terms, contact South Dakota Legal Aid or a private tenant's rights attorney. The South Dakota Attorney General's Consumer Protection Division also handles certain landlord complaints and can provide information on tenant rights under state law.
