What South Dakota law requires
South Dakota's landlord-tenant statute is concise, but the penalties behind it are not. S.D. Codified Laws § 43-32-6 imposes a hard 30-day deadline: within 30 calendar days of the tenant vacating, the landlord must either return the full deposit or hand over an itemized written statement of deductions along with any remaining balance. That's not two separate options with equal weight. Return in full, or explain every dollar kept, in writing, within 30 days.
Section 43-32-7 tightens that requirement further. An itemization is not just a list of dollar amounts. It must include the date each expense was incurred, the nature of the expense, and the specific amount for each deduction. A landlord who sends a vague note saying "cleaning: $300, repairs: $200" has not complied with § 43-32-7. That matters because a non-compliant itemization is treated the same as no itemization when a court is deciding whether retention was in bad faith.
The state also places the burden of proof on the landlord. Normal wear and tear is not deductible, and the landlord must demonstrate that any claimed damage goes beyond ordinary use. If the landlord can't show that, the deduction doesn't hold.
The 30-day clock and when it starts
The 30-day period begins when the tenant vacates and the landlord regains access to the premises. This is not the lease end date. It is not the last day you paid rent. It is the day you actually left and the landlord could walk back in. Handing over the keys is the clearest evidence of that moment. If you mailed the keys, the postmark matters. If you left without formal notice and the landlord had to determine you were gone, the clock may be disputed, which is exactly why documenting your move-out date in writing protects you.
Providing a forwarding address helps but is not a precondition for return. South Dakota law says the tenant's failure to provide a forwarding address does not excuse the landlord's duty to refund the deposit. It does affect how the landlord can get the money to you, but it does not extend the 30-day window or eliminate the obligation.
Once day 31 arrives with no deposit and no compliant itemized statement, the landlord's statutory protection evaporates. Every day past the deadline strengthens your bad-faith argument, and a demand letter sent on day 32 citing the specific statutory failures is substantially more powerful than one sent while the window is still technically open.
What you can recover
Your total potential recovery has three components.
The first is the deposit itself, or the wrongfully withheld portion. If your landlord kept $1,200 and provided no itemization, you're owed $1,200. If the landlord itemized $400 in legitimate repairs and kept $800 more without justification, the improper portion is $800.
The second is the bad-faith penalty under § 43-32-8. Twice the wrongfully withheld amount. On $800 improperly kept, that's $1,600 in statutory damages on top of the $800 you're already owed, for $2,400 total before fees.
The third is attorney's fees and court costs. South Dakota's fee-shifting statute makes this especially powerful in the demand-letter context. The landlord's calculus is not just "do I owe the tenant money." It's "if this goes to court and I lose, do I also pay the tenant's legal fees." That calculation changes behavior. Most landlords who receive a properly drafted demand letter citing § 43-32-8 by name resolve the dispute before a court filing is necessary.

Evidence you'll need before you write
A demand letter without documentation is a bluff. A demand letter backed by a clear evidence trail is a credible legal threat. Before you draft a word, gather the following.
Your lease is the foundation. It establishes the deposit amount, the move-in date, and what deductions the landlord was contractually permitted to take. Bring specific attention to any "cleaning fee" or "replacement" clauses, because those only hold if the lease authorizes them and the landlord can actually prove the cost.
Move-in and move-out condition records are the most important documents in a deposit dispute. Photos with metadata timestamps, a written move-in inspection report signed by both parties, and any email or text exchange confirming unit condition when you left. If your landlord provided a pre-move-out walkthrough and put anything in writing about the condition of the unit, that document is gold. Courts weight landlord-generated move-out statements heavily when the landlord later tries to claim damage.
Proof of deposit payment. A bank statement, a canceled check, or a receipt showing the amount paid and when.
Any written communications after move-out. Every email, text, letter, or voicemail where the landlord referenced the deposit, the timeline, or the condition of the unit. A landlord who said "I'll get back to you about the deposit" in writing two weeks after move-out and then went silent has created a documented paper trail that supports your claim.
If the landlord did send an itemized statement, preserve it. A non-compliant statement, as described above, is itself evidence that the statutory requirements weren't met.
Writing the South Dakota demand letter
The letter has one job: make clear to the landlord that paying now is significantly cheaper than defending a lawsuit later. It does that by being precise, citing the statute, and naming the exact dollar amount you expect.
Open with the facts. Full names of both parties, the rental address, your move-in and move-out dates, the deposit amount paid, and what, if anything, has been returned to you. This is not narrative, it's the factual record the letter is built on.
Cite the statutes directly. S.D. Codified Laws § 43-32-6 for the 30-day return requirement. § 43-32-7 for the itemization standards if the landlord's statement was deficient. § 43-32-8 for the bad-faith penalty and the fee-shifting provision. Landlords who have not consulted an attorney often don't know the fee-shifting clause exists. Naming it changes the conversation immediately.
State exactly what you're demanding. The unpaid deposit amount, plus the statutory penalty you'll seek in court if this isn't resolved. Give a deadline, 10 to 14 calendar days from delivery is standard and courts treat it as reasonable. Name the specific court you'll file in: South Dakota's small claims limit is $12,000, which covers most residential deposit disputes including the bad-faith multiplier.
Keep the tone factual. No adjectives about how unfair the situation is. No threats outside of what the statute provides. Courts respond to precision. Landlords respond to the cost of being wrong.
If the landlord doesn't pay
When your deadline passes without a response, file a South Dakota small claims case for a withheld security deposit to pursue the full penalty through the court. South Dakota's small claims limit of $12,000 covers most residential deposit disputes, including the 2× bad-faith multiplier on large deposits. Your demand letter becomes exhibit A the moment you walk into the courthouse, which is one more reason to get it right before you send it.
What to expect after the letter is sent
USPS Certified Mail gives you a delivery date, which becomes your clock start for the demand deadline. Most responses fall into one of three categories.
Full payment arrives within two weeks. This is the most common outcome when the letter is properly drafted, cites the statute, and names the penalty. The landlord does the math and pays. Keep the payment records, confirm the amount covers everything you demanded, and close the dispute in writing.
The landlord responds with a counter-offer or a revised itemization. This happens when the landlord believes some deductions are legitimate and is willing to negotiate the rest. Evaluate the revised itemization against § 43-32-7's requirements. If deductions are now properly documented and you agree with some of them, a partial settlement can resolve the dispute without court. Get any settlement in writing before you cash anything.
No response. Silence past your deadline is not ambiguity, it's a decision. A landlord who received the certified letter, who knows the statute, and who chose not to respond has given you a straightforward path to a bad-faith finding in small claims court. File promptly. The 30-day window has already closed, and every additional day of silence strengthens the case that the retention was not in good faith.
South Dakota judgments carry post-judgment interest, and the fee-shifting provision means that a tenant who wins in small claims can recover legal costs on top of the original amount. Landlords who do the math before the hearing date typically settle before it.
