South Dakota Security Deposit Laws: The One-Month Cap, 14-Day Return, and the Two-Hundred-Dollar Penalty

South Dakota security deposit law is built on two short statutes — Codified Laws section 43-32-6.1, which caps the deposit at one month’s rent, and section 43-32-24, which sets the return deadline, the itemized accounting, and the penalty for getting it wrong. The rules are compact, but the deadlines are unforgiving: a landlord who returns the deposit and a written statement on time is on solid ground, while one who misses the two-week deadline or skips the accounting can forfeit the right to keep anything and owe a penalty on top. This guide walks the whole South Dakota framework end to end: how much you may collect, what you can and cannot deduct, the two-week return clock and the forty-five-day accounting, the absence of any interest rule, and the up-to-two-hundred-dollar penalty a court can impose for bad-faith withholding.

Whether you own one rental in Sioux Falls or a small portfolio across the state, the rules below apply the same way, because sections 43-32-6.1 and 43-32-24 govern statewide. South Dakota has no local rent boards layering interest or extra notice steps on top, so the framework here is the whole picture for most landlords. Everything here is general information, not legal advice; confirm the current figures and consult a licensed South Dakota attorney before acting on a specific dispute.

Below, a short overview video summarizes the South Dakota deposit rules; the sections that follow break down each piece in detail — the one-month cap and its special-conditions exception, deductions versus normal wear and tear, the two-week return timeline, the itemized accounting, the interest question, penalties, the move-out walkthrough, and the small-claims path if a dispute cannot be resolved.

The starting rule in South Dakota is simple: the deposit is capped at one month’s rent. Under South Dakota Codified Laws section 43-32-6.1, a lessor of residential premises may not demand or receive a security deposit in an amount or value greater than one month’s rent. The statute also fixes what counts as a deposit in the first place: any money whose function is to secure the performance of a residential rental agreement, or any part of that agreement, is deemed a security deposit — no matter what the lease calls it. That definition matters, because it prevents a landlord from dodging the deposit rules by relabeling the same money as a fee.

There is one exception, and it is narrow. A larger deposit may be agreed on between the landlord and the tenant where special conditions pose a danger to the maintenance of the premises. In plain terms, if something about the tenancy — a pet, a home business, or another circumstance that genuinely raises the risk to the unit — creates a real threat to the property, the parties may agree in writing to a deposit above one month’s rent. The exception is not a loophole for charging more across the board; it requires an actual special condition and a mutual agreement, ideally documented in the lease.

Put the Amount in the Lease

Set the deposit at or below one month’s rent and state the exact amount in the lease. If you are relying on the special-conditions exception for a higher figure, name the condition and record the tenant’s written agreement in the lease itself. The sharper rules in South Dakota are not about the cap — most landlords stay at or under one month’s rent without difficulty — but about the return: the two-week deadline and the penalty for bad-faith retention, which is where nearly every deposit dispute actually arises.

A security deposit secures the landlord against specific losses, not against the ordinary passage of time. South Dakota recognizes a limited set of purposes for a lawful deduction, and the landlord who charges outside them invites a dispute — and, if the withholding is in bad faith, a penalty.

Permitted Deductions

• Unpaid rent. Rent that remains owed for the final month or any earlier period of the tenancy.
• Unpaid utilities the tenant owed. Utility charges the lease makes the tenant’s responsibility that were left unpaid at move-out.
• Repair of damage beyond ordinary wear and tear. The cost to repair a cracked window, a pet-stained carpet, a hole punched in a wall, or similar damage the tenant or their guests caused.

Not Deductible — Ordinary Wear and Tear

Ordinary wear and tear is the natural deterioration that comes from living in a unit normally, and the landlord must absorb it. In South Dakota these are treated as non-deductible:

• Faded or lightly scuffed paint, and small nail holes from hanging pictures.
• Carpet worn thin along walkways from ordinary foot traffic, with no stains or pet damage.
• Minor marks, loose grout, or aged caulk around tubs and sinks.
• Worn but still-functioning appliances and fixtures that simply reached the end of their useful life.

The deadline South Dakota landlords miss most often is the two-week return rule. Under South Dakota Codified Laws section 43-32-24, within two weeks — fourteen days — after the tenancy ends and the landlord receives the tenant’s forwarding mailing address or delivery instructions, the landlord must do one of two things: return the deposit, or furnish the tenant a written statement showing the specific reason for withholding the deposit or any portion of it. Two events start the clock together: the end of the tenancy and receipt of the tenant’s address.

The Itemized Accounting Within Forty-Five Days

The two-week statement is not the end of the landlord’s duty. Under section 43-32-24, when the landlord has withheld part of the deposit, the tenant may request an itemized accounting, and the landlord must provide it within forty-five days after the tenancy ends. Think of it as two layers: within two weeks, return the money or state the reason for withholding; then, on the tenant’s request, deliver a detailed line-by-line accounting within forty-five days. A landlord who takes deductions should be ready to itemize each one — naming the deduction and its amount — and to back each line with evidence.

The Forwarding Address Starts the Clock

Because the two-week deadline runs from the end of the tenancy and the landlord’s receipt of the tenant’s forwarding address, a tenant who wants a prompt refund should provide that address at move-out. For the landlord, the practical rule is the mirror image: the day the tenant’s forwarding address arrives, calendar the fourteen-day deadline and mail the statement and any refund to that address by a method you can prove. Do not sit on the funds — once the tenancy has ended and the address is in hand, the clock is running.

A South Dakota deduction is only as good as the written record that supports it. When you keep any part of a deposit, the tenant is entitled to a statement of the specific reason within two weeks and, on request, an itemized accounting that names each deduction and its amount within forty-five days. A lump-sum figure with no breakdown does not satisfy section 43-32-24 and is treated as if no accounting was given, which puts the whole withholding at risk.

Tie each line on that accounting to evidence: a dated move-in and move-out photo, a signed condition checklist, and the invoice or estimate behind the repair. The difference between a deduction that survives and one that gets reversed is almost always the paper trail. “Professional carpet cleaning to remove pet odor, invoice attached” survives; a bare line that reads “cleaning” with a number and nothing behind it does not. Our guide to South Dakota habitability laws explains the maintenance baseline that separates the landlord’s own upkeep duty from damage you may charge to the tenant, and a documented South Dakota move-in and move-out checklist keeps the condition record consistent from one tenancy to the next.

South Dakota keeps this part simple. There is no statewide requirement to pay interest on a security deposit, and no requirement to hold the deposit in a separate escrow account. A landlord may hold the deposit during the tenancy in an ordinary account and pay no interest, which is entirely lawful. The only holding-related obligation is the one that matters most: returning the deposit, or the written statement of reasons, within the two-week window of section 43-32-24.

Even without an interest or escrow mandate, holding the deposit separately from operating cash is sound practice. It keeps the two-week return clean, and it gives you a clear record if a tenant later disputes how the money was handled. A deposit that has been commingled with rent and expenses for a year is harder to account for than one that sat untouched in its own account.

South Dakota backs its deposit rules with real teeth. Under South Dakota Codified Laws section 43-32-24, a landlord who in bad faith retains a deposit or any portion of it — including by failing to provide the required written statement and itemized accounting — is liable to the tenant for the amount wrongfully withheld plus punitive damages of up to two hundred dollars, together with the tenant’s costs. And separately, a landlord who fails to comply with the section forfeits all right to withhold any portion of the deposit. The two consequences stack: forfeiture of the deduction, and a penalty on top.

Bad faith is not merely being wrong about a deduction. It generally means the landlord acted unreasonably — ignoring the two-week deadline, refusing to itemize, inventing charges, or keeping the deposit with no legitimate basis. Because that exposure attaches to a bad-faith failure to meet the deadline or account for the deductions, a landlord with an otherwise reasonable deduction can still face the penalty by being late or by failing to provide the itemized accounting on request. The pattern is consistent: the penalty is rarely about the deduction itself and almost always about missing the deadline or skipping the itemized statement.

Put the rules together and the South Dakota move-out becomes a repeatable checklist rather than a judgment call. Follow this sequence and penalty exposure all but disappears.

A thorough move-out record starts at move-in. Use a documented South Dakota move-in and move-out checklist and photographs at both ends so you can prove exactly what the tenant caused. When you do withhold, a clean South Dakota security deposit return letter keeps the statement and accounting organized and defensible.

Most deposit disputes never reach a courtroom, but when they do in South Dakota, they usually land in small claims court — a forum designed to be used without a lawyer. As of 2026, a South Dakota small claims case can be brought for amounts up to twelve thousand dollars, which comfortably covers a deposit dispute and the statutory two-hundred-dollar penalty in most cases. Verify the current limit, which the Legislature can adjust over time.

The pattern is consistent: South Dakota deposit cases are won on paper. The landlord who documents condition at both ends, itemizes clearly, and mails the statement on time rarely loses — and the tenant who keeps their own photos and a copy of the written statement is equally well positioned to recover a wrongful withholding, along with the up-to-two-hundred-dollar penalty for a bad-faith retention.

How you set and handle a deposit is governed by fair housing law just as screening is. Charging a higher deposit, or applying a stricter deduction standard, to a tenant because of race, color, religion, sex, national origin, familial status, or disability is housing discrimination under the federal Fair Housing Act, which applies in South Dakota regardless of the state’s own deposit rules. The special-conditions exception in section 43-32-6.1 is about a danger to the premises, never about the characteristics of the person renting.

The safeguard is a uniform policy: one deposit amount within the legal cap, one condition standard, and one return process applied to every tenant alike. A landlord who charges a family with children a larger deposit, or who scrutinizes a disabled tenant’s unit more harshly at move-out, invites a fair housing complaint on top of any state-law deposit claim. Apply the same even-handed discipline to deposits that you apply to screening, and document that the same rules ran for every tenant.

Beyond a routine move-out, a handful of situations trip up South Dakota landlords because the deposit rules interact with other events. Three come up often.

Roommates and a Single Deposit

Where several tenants share a lease and a single deposit, South Dakota treats the deposit as one sum tied to the tenancy, not as separate shares. When one roommate leaves and another stays, the landlord’s two-week obligation is generally triggered only when the tenancy as a whole ends and the unit is surrendered — not each time one roommate moves out mid-lease. Sorting out each roommate’s share of a refund is usually a private matter among the tenants. Return the single deposit to the tenants collectively unless the lease or a written agreement directs otherwise, and avoid getting drawn into splitting it.

When the Property Is Sold

If a landlord sells the rental, the security deposit does not simply disappear with the change of ownership. The sound practice — and the one that protects a buyer — is to transfer the remaining deposit (after any lawful deductions) to the new owner with a written accounting, or to return it to the tenant, and to document the handoff in escrow. A landlord buying an occupied South Dakota property should confirm in the purchase documents that deposits are transferred and itemized, because the return obligation under section 43-32-24 ultimately follows the tenancy, and an undocumented deposit becomes the new owner’s problem at move-out.

Pet Deposits and the Special-Conditions Exception

A pet is a common reason a landlord considers a larger deposit. In South Dakota, a pet deposit is still a security deposit — money held to secure the tenancy — and is subject to the return and accounting rules of section 43-32-24. Where a pet genuinely poses a special condition that endangers the maintenance of the premises, section 43-32-6.1 allows a deposit above one month’s rent by written agreement. Keep any pet deposit within that framework: put it in writing, tie it to the actual risk, and refund or account for it at move-out like any other deposit. Note that a service animal or assistance animal is not a pet under fair housing law, and a landlord cannot charge a pet deposit for one.

A security deposit is a backstop, not a substitute for screening. A deposit of one month’s rent rarely covers the full cost of unpaid rent plus damage plus an eviction, so the better protection is renting to a qualified tenant in the first place. The deposit then handles the smaller, ordinary losses it was actually meant for.

Screen every applicant to the same standard: get written consent, pull a consumer report for a permissible purpose under the federal Fair Credit Reporting Act, and send an adverse action notice if the report drives a denial. Our South Dakota tenant screening laws page covers the screening half of the picture, and the broader security deposit laws by state guide lets you compare South Dakota to wherever else you rent. That last point is where most disputes are actually won — before the lease is ever signed. A prior eviction, a pattern of damage, or unstable finances rarely appears out of nowhere; it usually leaves a trail an applicant’s history reveals.

Every rule above ultimately turns on proof. Because South Dakota ties the deposit to a deadline and an itemized statement, your records are what prove you complied. The landlord who cannot document a charge loses it — regardless of whether the damage was real. Build the evidence file across the whole tenancy, not at the end.

At Move-In

• A written condition checklist, room by room, signed and dated by the tenant.
• Timestamped photos or video of every wall, floor, fixture, and appliance, stored where the date cannot be doubted.
• The signed lease showing the deposit amount and any special-condition agreement supporting a higher figure.

During the Tenancy

• A dated log of every maintenance request and the landlord’s response, which also rebuts a habitability defense.
• Records of any lawful entry to inspect or repair, made with proper notice — see South Dakota landlord entry laws.
• The holding record — the account where the deposit sat — so you can show the money was handled properly.

At Move-Out

• A second set of timestamped photos taken at surrender, to compare against move-in.
• Invoices, receipts, or a documented cost basis for every charge on the itemized accounting.
• The written statement of reasons and proof it was mailed within two weeks of receiving the forwarding address.
• The itemized accounting, delivered within forty-five days if the tenant requested it.

The cheapest deposit dispute is the one that never happens. A few disciplined habits protect a South Dakota landlord across an entire portfolio.

• Document move-in exhaustively. A signed checklist and dated photos of every room create the baseline that decides every future deduction.
• Set the deposit at one month’s rent, and no higher unless a genuine special condition posing a danger to the premises supports more by written agreement.
• Deduct only for unpaid rent, tenant-owed utilities, and real damage — never for ordinary wear and tear or routine cleaning.
• Calendar the two-week deadline the day the tenancy ends and the forwarding address arrives, and mail the statement with proof well before it expires.
• Itemize every deduction and be ready to deliver the accounting within forty-five days on request.
• Screen carefully before you ever hand over keys. The tenants most likely to leave a unit in disputed condition are often the ones a thorough screening would have flagged.

That last point is where most disputes are actually won — before the lease is ever signed. Screening for a prior eviction, a pattern of damage, or unstable finances is the single highest-leverage habit a South Dakota landlord can build.
