South Dakota Security Deposit Law: Return Deadline, Limits, and How to Get It Back

In South Dakota, your landlord generally must return your security deposit within two weeks after your tenancy ends and you move out. The deposit itself is usually capped at one month's rent, though a landlord may charge more under certain circumstances. If the landlord keeps any part of your money, you can demand a written, itemized statement of the deductions, and the landlord must provide it within 45 days of move-out. These rules come from South Dakota's landlord-tenant statutes in the South Dakota Codified Laws (often cited around SDCL Chapter 43-32); because section numbers and figures can change, confirm the current law before relying on a specific number.

How much can a South Dakota landlord charge?

South Dakota is one of the states that caps the standard security deposit. The general rule is that a landlord may not require a deposit larger than one month's rent. There is an exception: a landlord may demand a higher amount when special conditions exist that pose a danger to the property or a higher-than-usual risk of damage. If your landlord asked for more than one month's rent, ask why, and get the reason in writing.

• The cap applies to the refundable security deposit, not necessarily to separate, clearly disclosed nonrefundable fees (such as a stated pet fee), so read your lease carefully.
• Last month's rent collected up front is treated differently from a damage deposit; how it is labeled in your lease matters.

The two-week deadline and the 45-day itemized statement

This is where South Dakota's rules trip up a lot of landlords and tenants. There are really two clocks running:

• Two weeks to act. Within roughly two weeks after the tenancy ends, the landlord must either return the full deposit or return the balance after deductions.
• 45 days for the breakdown. If the landlord withholds any amount, you have the right to request an itemized written accounting of why, and the landlord must supply it within 45 days of the end of the tenancy.

Give your landlord a written forwarding address when you move out, and keep a copy. Without an address to send the check and statement to, you make it easier for a landlord to claim they could not reach you.

What can and cannot be deducted

A landlord may deduct for unpaid rent and for actual damage beyond normal wear and tear. The wear-and-tear line is the heart of most disputes. You are not responsible for the ordinary aging of a unit you lived in.

• Usually deductible: unpaid rent, holes in walls, broken fixtures or appliances you damaged, pet stains and odors, cleaning to return the unit to its move-in condition, and removing trash or belongings you left behind.
• Usually NOT deductible (normal wear and tear): faded or lightly scuffed paint, minor carpet wear in walkways, small nail holes from hanging pictures, worn-out caulk or grout, and general fading from sunlight.

Your single best protection is documentation. Take dated photos or video at move-in and again at move-out, and complete any move-in checklist your landlord provides. Pictures of a clean, undamaged unit are hard to argue with.

Interest on deposits

South Dakota law does not generally require landlords to pay interest on a routine residential security deposit, and there is no statewide rule that deposits be held in a separate interest-bearing account. If your lease promises interest, the landlord must honor that promise. Some local ordinances can add requirements, so it is worth checking the rules for your specific city or county.

Penalties for wrongful withholding and how to sue

If a landlord keeps your deposit in bad faith, South Dakota law allows you to recover more than just the amount wrongly withheld. The statute provides for a penalty on top of the withheld funds plus potential damages, which is meant to discourage landlords from sitting on deposits they have no real basis to keep. To recover the penalty you generally must show the landlord acted in bad faith, not merely that you disagree about an amount.

• Send a demand letter first. Write to the landlord, state the deposit amount, reference the missing itemized statement or improper deductions, and ask for return by a specific date. Keep proof of mailing.
• Small claims court. In South Dakota, deposit disputes are typically filed in the small claims division of the magistrate court (part of the circuit court system). Small claims is designed for people without lawyers, with a simplified process and a modest filing fee.
• Bring your evidence. Your lease, the move-in and move-out photos, your written forwarding address, the demand letter, and any itemized statement (or proof none arrived) are what win these cases.

If the amount is large, the facts are tangled, or the landlord has a lawyer, it can be worth consulting a South Dakota landlord-tenant attorney or contacting East River Legal Services or Dakota Plains Legal Services, which assist lower-income South Dakotans.

Landlord-tenant law changes and can have city or county exceptions, so confirm the current South Dakota rules or talk with a local attorney before you act.
