Minnesota Security Deposit Laws: No Cap, 1% Interest, 21-Day Return, and Penalties
No Statutory Cap · 1% Simple Interest · 3-Week Return · Itemized Statement · Deductions · Penalties
Minnesota security deposit law is set almost entirely by one statute — Minnesota Statutes section 504B.178 — and it works differently from most states. Minnesota puts no dollar cap on how much you may collect, but it does something few states do: it requires the landlord to pay one percent simple annual interest on the deposit, and to return the deposit plus that interest within three weeks after the tenancy ends. This guide walks the whole Minnesota framework end to end: how much you may collect, the mandatory interest, the three-week return deadline and the shorter five-day condemnation deadline, what you can and cannot deduct, the written itemized statement, non-refundable fees, and the punitive-damages penalty a court can impose when a landlord keeps a deposit in bad faith.
Whether you own one duplex in Duluth or a small portfolio in the Twin Cities, the rules below apply the same way, because Minnesota Statutes section 504B.178 governs statewide. The distinctive Minnesota wrinkle is the interest obligation — it is easy to forget, and forgetting it carries its own penalty. Everything here is general information, not legal advice; confirm the current figures and consult a licensed Minnesota attorney before acting on a specific dispute.
Below, a short overview video summarizes the Minnesota deposit rules; the sections that follow break down each piece in detail — the absence of a cap, the interest requirement, the return timeline, deductions versus normal wear and tear, penalties, the move-out walkthrough, and the conciliation-court path if a dispute cannot be resolved.

No Statutory Cap — but Real Obligations Instead
The first thing to understand about Minnesota is what it does not do: it does not cap the security deposit. Unlike states that limit a deposit to one or two months’ rent, Minnesota Statutes section 504B.178 sets no maximum dollar amount. A landlord may set a deposit at whatever the market bears — most commonly one to two months’ rent — provided it is reasonable and clearly stated in the lease. If a lease form or an online guide tells you Minnesota limits the deposit to a set number of months, it is describing another state’s law, not Minnesota’s.
What Minnesota asks in exchange for that flexibility is discipline on the back end. Two obligations do the real work: the landlord must pay interest on the deposit, and must return it quickly with a written accounting. Those two rules — not a cap — are where Minnesota landlords get into trouble, and they are the heart of this guide.
“No Cap” Is Not “No Rules”
The absence of a cap tempts some landlords to think Minnesota is a light-touch state. The opposite is true at move-out. Minnesota is one of a small group of states that require interest on the deposit, and the three-week return deadline is short. A landlord who collects a large deposit and then forgets the interest or misses the deadline faces a penalty that can dwarf any deduction. Treat the freedom to set the amount as a reason to be more careful at return, not less.
Takeaway
Minnesota sets no dollar cap on the security deposit — one to two months’ rent is typical. In exchange, the landlord must pay one percent simple annual interest and return the deposit with a written statement within three weeks. The obligations live at move-out, not at signing. Verify the current law before relying on any figure.
The One Percent Interest Rule — Minnesota’s Distinctive Feature
Here is the rule most landlords miss. Under Minnesota Statutes section 504B.178, every residential security deposit must earn simple, noncompounded interest at one percent per year, and that interest belongs to the tenant. It is not optional, and it is not tied to whether the landlord actually invested the money — the one percent is owed regardless of where the deposit is held. This is the single most distinctive feature of Minnesota deposit law, and the one that most often trips up out-of-state owners and older lease templates.
How the Interest Is Calculated
The interest is simple, not compounded. That means it is figured on the original deposit amount each year, and the prior year’s interest is not folded back in to earn more interest. The clock runs from the first day of the month after the deposit is paid in full, and stops on the last day of the month in which the landlord, in good faith, returns the deposit — or on the day judgment is entered in a lawsuit over the deposit, whichever comes first. There is no minimum holding period the deposit must clear before interest starts; it accrues from that first month forward.
A Simple Worked Example
Suppose a tenant pays a deposit equal to one thousand dollars and stays two years. At one percent simple interest, the deposit earns ten dollars per year, so the landlord owes the tenant the one thousand dollars plus twenty dollars of interest at move-out, less any lawful deductions. Because the interest is simple, the second year earns the same ten dollars as the first — it is not calculated on one thousand and ten dollars. The amounts are modest, but skipping them entirely is a violation that carries its own penalty.
Why the Interest Matters More Than Its Size
The dollar figures are small, which is exactly why landlords ignore them — and exactly why that is a mistake. Minnesota Statutes section 504B.178 treats the interest as part of the deposit, so withholding the interest in bad faith is itself a violation, separate from wrongly keeping the principal. A landlord who returns the full principal on time but never pays the accrued interest has still failed to comply, and can be liable for the withheld interest as a penalty. The lesson is to build the one percent calculation into every return, no matter how small the number.
Takeaway
Minnesota requires one percent simple annual interest on every deposit, owed to the tenant regardless of where the money sits. It runs from the first month after payment until a good-faith return, and it is not compounded. The amounts are small, but skipping the interest is a separate violation — always add it to the return.
The Three-Week Return Deadline and the Five-Day Exception
The deadline Minnesota landlords miss most often is the three-week return rule. Under Minnesota Statutes section 504B.178, within three weeks after the tenancy terminates — and after the tenant has provided a mailing address or delivery instructions — the landlord must do one of two things: return the deposit with its interest, or furnish the tenant a written statement showing the specific reason for withholding any part of it. Three weeks is short, so the deadline should be calendared the moment the tenant surrenders and gives an address.
The Five-Day Condemnation Deadline
There is a much shorter deadline in one situation. When the tenant must leave because the building or dwelling is legally condemned — for reasons not caused by the tenant’s own willful, malicious, or irresponsible conduct — the landlord has only five days from the date the tenant leaves to return the deposit. This five-day rule is narrow and applies only to condemnation; it does not apply to an ordinary eviction or a routine move-out, both of which run on the standard three-week clock.
Get the Deadline Right — It Is Three Weeks, Not a Month
A common error, repeated in stale guides, is to describe Minnesota’s return deadline as thirty days or to confuse the five-day condemnation window with evictions. Neither is correct. The default deadline is three weeks, and the five-day rule applies only to legal condemnation of the building through no fault of the tenant. Missing the three-week deadline is the classic path to a bad-faith finding, so treat it as a hard date and verify the current statute if anything you read says otherwise.
What the Written Statement Must Include
When the landlord withholds any part of the deposit, the written statement must show the specific reason for the withholding. A vague line such as “cleaning” or “repairs” is not specific enough to survive a challenge; the statement should identify each deduction, describe the damage or charge, and give the amount. Attaching invoices, estimates, or receipts is not always strictly required by statute, but it is the practical difference between a deduction that holds up and one a court disallows. Pair the statement with the returned balance and the accrued interest, all within three weeks.
No Forwarding Address? The Clock Waits for the Address
Minnesota ties the three-week duty to the tenant providing a mailing address or delivery instructions. If the tenant leaves no address, the landlord’s clock does not run until one is provided — but a landlord should still request an address in writing at move-out and document the date it arrives, because that date starts the deadline. A tenant, for their part, should always give a written forwarding address promptly, since the deposit cannot be returned to an unknown address.
Takeaway
Return the deposit, the interest, and a written statement of any deductions within three weeks after the tenancy ends and the tenant gives a mailing address — or within five days if the building is legally condemned. Miss the deadline and you invite a bad-faith finding and up to five hundred dollars in punitive damages.
What a Landlord May Deduct — and What Counts as Wear and Tear
Minnesota Statutes section 504B.178 lets a landlord withhold from the deposit only for a limited set of reasons. The landlord bears the burden of justifying each deduction in the written statement, so anything not clearly owed is presumed to be the landlord’s cost to absorb.
Permitted Deductions
- Unpaid rent. Rent that remains owed for the final month or any earlier period.
- Damage beyond ordinary wear and tear. Repair of harm the tenant or their guests caused — broken fixtures, large holes, pet-stained flooring, and similar damage that goes past normal use.
- Other amounts lawfully owed under the lease or statute. This can include unpaid utilities the landlord had to cover and other charges the tenant is obligated to pay, where the lease and Minnesota law support them.
- Cleaning beyond routine turnover. The reasonable cost to address filth, smoke damage, or pet contamination that goes beyond the ordinary cleaning any unit needs between tenants — not a blanket “make it spotless” charge.
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. Minnesota treats these 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 caulk that has aged around tubs and sinks.
- Worn but still-functioning appliances and fixtures that simply reached the end of their useful life.
The Prorating Rule for Paint and Carpet
Even when repainting or carpet replacement is justified by real damage, a landlord generally cannot charge the tenant the full cost of a brand-new surface. Paint and carpet have an expected useful life, so the charge should be prorated for age — a tenant who damaged a carpet already several years into its life should pay only for the remaining life, not a whole new carpet. Billing the full amount for an old surface is a common way Minnesota landlords lose deposit disputes.
Takeaway
You may withhold only for unpaid rent, damage beyond ordinary wear and tear, and other amounts the tenant lawfully owes — plus cleaning past routine turnover. Faded paint, worn carpet, and small nail holes are wear and tear you absorb. Prorate paint and carpet for age; never bill a tenant for a brand-new surface.
Non-Refundable Fees and Separate Accounts
Two points confuse Minnesota landlords, and both cut against treating deposit money loosely. First, a true security deposit is refundable and must be accounted for at move-out under Minnesota Statutes section 504B.178. A landlord cannot rename a refundable deposit a “non-refundable fee” to escape the interest and return rules — any sum that functions as security for damage or unpaid rent is treated as a deposit no matter what the lease calls it. A charge that is genuinely for a distinct service, clearly disclosed in the lease, is analyzed on its own terms, so the safe practice is to label and treat each charge accurately rather than paper over a deposit with a different name.
Second, Minnesota does not require a separate escrow account for security deposits. A landlord may hold deposits in a general account, and many do. But the interest obligation applies regardless: whether or not the money is segregated, the tenant is owed one percent simple annual interest. Keeping deposits in a separate ledger is a sound accounting habit that makes the interest and return calculations cleaner, even though the statute does not command it.
Pet Deposits Ride the Same Rules
A pet deposit is allowed in Minnesota, but calling it a “pet fee” does not make it non-refundable if it functions as security for pet-related damage. Whatever the label, a sum held against damage is subject to the same interest and three-week return rules. Note too that a landlord cannot require a pet deposit for a service animal or a qualified emotional-support animal, which are not “pets” under fair-housing rules — a separate area of law worth confirming for any assistance-animal request.
Penalties for Bad-Faith Withholding
Minnesota backs the deposit rules with real teeth. Under Minnesota Statutes section 504B.178, a landlord who retains the deposit, the interest, or any part of it in bad faith is liable for punitive damages of up to five hundred dollars per deposit, in addition to the wrongfully withheld amount and its interest. That five-hundred-dollar figure is a statutory penalty layered on top of returning what was kept, and it applies per deposit.
Bad faith is not merely being wrong about a deduction. It generally means the landlord acted unreasonably — and importantly, Minnesota commonly treats a landlord’s failure to return the deposit or furnish the written statement within the deadline as evidence of bad faith. A landlord who blows past three weeks with no accounting is squarely in the danger zone. A landlord who returns the deposit, the interest, and a clear written statement on time is well protected even if a specific deduction is later disputed.
How the Penalty Math Adds Up
Consider a landlord who keeps a tenant’s entire deposit with no written statement and past the three-week deadline. The tenant can recover the wrongfully withheld deposit, the unpaid interest, and up to five hundred dollars in punitive damages — and because conciliation court disputes are inexpensive to file, tenants pursue them. Add the possibility of costs, and the total quickly exceeds any legitimate deduction the landlord might have claimed. The cost of doing it right is trivial next to the cost of doing it wrong.
The Move-Out Procedure, Step by Step
Put the rules together and the Minnesota move-out becomes a repeatable checklist rather than a judgment call. Follow this sequence and penalty exposure all but disappears.
Request the forwarding address in writing
At or before move-out, ask the tenant for a mailing address or delivery instructions and record the date it arrives. That date, together with surrender, starts the three-week clock.
Inspect and photograph at surrender
When the tenant returns the keys, inspect promptly and photograph every room. Compare against the signed move-in checklist to separate tenant damage from wear and tear.
Calculate lawful deductions
Withhold only for unpaid rent, damage beyond wear and tear, and other amounts lawfully owed. Prorate paint and carpet for age. Gather an invoice or cost basis for each charge.
Add the one percent interest
Figure one percent simple annual interest on the deposit for the holding period and add it to the amount returned, as the statute requires.
Return within three weeks with a written statement
Mail or deliver the remaining deposit, the interest, and a written statement of the specific reasons for any withholding within three weeks — five days if the building is condemned — keeping proof of mailing.
A thorough move-out record starts at move-in. Use a documented Minnesota 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 Minnesota security deposit itemization form keeps the statement organized and defensible.
When a Dispute Reaches Conciliation Court
Most deposit disputes never reach a courtroom, but when they do in Minnesota, they usually land in conciliation court — the state’s small-claims forum, designed to be used without a lawyer. As of 2026, the conciliation court limit is twenty thousand dollars, raised from fifteen thousand effective August first, 2024, which comfortably covers a deposit dispute plus the interest and the punitive-damages penalty in nearly every case. Verify the current limit, which the Legislature adjusts over time.
✓ The Landlord Who Wins
- Signed move-in checklist plus dated move-in photos.
- Written request for the tenant’s forwarding address, with the date received.
- Deposit, interest, and written statement delivered within three weeks.
- The one percent interest calculated and paid, however small.
- Proof of mailing (certified mail or a tracked method).
✕ The Landlord Who Loses
- No move-in documentation to compare against.
- A vague statement listing “cleaning” or “painting” with no detail.
- Deductions for ordinary wear and tear.
- The one percent interest forgotten entirely.
- A return sent after the three-week deadline.
The pattern is consistent: Minnesota deposit cases are won on paper. The landlord who documents condition at both ends, calculates the interest, itemizes clearly, and delivers 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.
Special Situations: Sale of the Property, Roommates, and Rent Increases
Beyond a routine move-out, a handful of situations trip up Minnesota landlords because the deposit rules interact with other events. Three come up often.
When the Property Is Sold
If a landlord sells the rental, the security deposit obligation follows the property. Minnesota law generally makes the buyer — the successor in interest — responsible for the deposits on the units they acquire, so a seller should transfer the remaining deposits, with the accrued interest, to the new owner and give the tenants written notice of the transfer, or return the deposits directly with a full accounting. A landlord buying an occupied Minnesota property should confirm in the closing that deposits and their accrued interest are transferred and documented, because the obligation to the tenant does not disappear at sale.
Roommates and a Single Deposit
Where several tenants share a lease and a single deposit, Minnesota treats the deposit as one sum tied to the tenancy, not as separate shares. When one roommate leaves and another stays, the landlord’s three-week obligation is generally triggered 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. Landlords should return the single deposit, with interest, to the tenants collectively unless the lease or a written agreement directs otherwise, and avoid getting drawn into splitting it.
The Deposit and a Rent Increase
Because Minnesota sets no cap, a rent increase does not automatically entitle a landlord to demand more deposit, and topping up a deposit mid-lease should be handled through a clear, agreed lease change rather than a unilateral demand. Landlords weighing a rent increase should review the separate rules that govern it — see our guide to Minnesota rent increase laws — and should not treat a permitted rent bump as a license to grab a larger deposit from a sitting tenant. Set the deposit correctly at signing and document any later change.
Documentation: the Evidence That Wins Deposit Cases
Every rule above ultimately turns on proof. Minnesota places the burden on the landlord to justify each deduction, which means 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.
- A written note of any pre-existing wear, so it is never later charged to the tenant.
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 under Minnesota entry rules — see Minnesota landlord entry laws.
At Move-Out
- The written request for the forwarding address and the date it was received.
- A second set of timestamped photos taken at surrender, to compare against move-in.
- Invoices, estimates, or a documented in-house cost for every charge, tied to a specific reason in the written statement.
- The one percent interest calculation, and proof that the deposit, interest, and statement were sent within three weeks.
The Single Most Common Failure
The deduction Minnesota landlords lose most often is the vague one: a line that reads “cleaning” or “painting” with a number and nothing behind it. A tenant can challenge that in conciliation court and usually win, because the landlord cannot show the work, the cost, or that it went beyond ordinary wear and tear. Specificity is the whole game — “professional carpet cleaning to remove pet odor, invoice attached” survives; “cleaning” does not.
Landlord Best Practices to Avoid Deposit Disputes Entirely
The cheapest deposit dispute is the one that never happens. A few disciplined habits protect a Minnesota 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 a reasonable deposit and state it clearly. Minnesota sets no cap, but a deposit far above one to two months’ rent invites disputes; put the amount and its purpose plainly in the lease.
- Build the interest into every return. Calculate the one percent simple annual interest as a matter of routine; forgetting it is a separate violation.
- Request the forwarding address in writing and log the date it arrives, because it starts the three-week clock.
- Calendar the three-week deadline at surrender and mail the deposit, interest, and statement with proof, well before it expires.
- 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. 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. Screening for it is the single highest-leverage habit a Minnesota landlord can build.

Frequently Asked Questions
How much can a landlord charge for a security deposit in Minnesota?
Minnesota Statutes section 504B.178 sets no statutory dollar cap on a residential security deposit, so a landlord may set a reasonable amount, most commonly one to two months’ rent. What Minnesota does require is different from a cap: the landlord must pay one percent simple annual interest on the deposit and return it, with that interest, within three weeks after the tenancy ends. Verify the current law, as figures change.
How long does a Minnesota landlord have to return a security deposit?
Under Minnesota Statutes section 504B.178, the landlord must return the deposit and any interest, or furnish a written statement of the reasons for withholding, within three weeks after the tenancy ends and the tenant provides a mailing address or delivery instructions. The deadline shrinks to five days when the tenant must leave because the building is legally condemned through no fault of the tenant.
Does a Minnesota landlord have to pay interest on a security deposit?
Yes. This is the distinctive feature of Minnesota law. Minnesota Statutes section 504B.178 requires the landlord to pay simple, noncompounded interest at one percent per year on the security deposit. The interest runs from the first day of the month after the deposit is paid until the landlord returns it in good faith, and it must be paid along with the deposit. Withholding the interest in bad faith carries its own penalty.
Is there a penalty if a Minnesota landlord wrongfully keeps a deposit?
Yes. Under Minnesota Statutes section 504B.178, a landlord who retains a deposit or the interest in bad faith is liable for punitive damages of up to five hundred dollars per deposit, on top of the wrongfully withheld amount and its interest. Bad faith is commonly presumed when a landlord misses the deadline or fails to furnish the written statement of reasons, which makes the three-week deadline the single most important date to protect.
Can a Minnesota landlord charge a non-refundable deposit or fee?
A true security deposit in Minnesota is refundable and must be accounted for under Minnesota Statutes section 504B.178, with interest, at move-out. A landlord cannot rename a refundable deposit a non-refundable fee to escape those rules. Any sum that functions as security for damage or unpaid rent is treated as a deposit. Charges genuinely for a service, clearly disclosed in the lease, are analyzed on their own terms, so label and treat each charge accurately.
What can a Minnesota landlord deduct from a security deposit?
A landlord may withhold from the deposit for unpaid rent and for damage to the premises beyond ordinary wear and tear, along with other amounts the tenant lawfully owes under the lease or statute, such as unpaid utilities the landlord had to cover. The landlord may not deduct for ordinary wear and tear — faded paint, lightly worn carpet, or small nail holes — and bears the burden of justifying every charge in the written statement.
Does a Minnesota tenant have to give a forwarding address to get the deposit back?
Practically, yes. Minnesota Statutes section 504B.178 ties the landlord’s three-week return duty to the tenant providing a mailing address or delivery instructions, so a tenant who leaves no address can delay the clock. A tenant should always give a written forwarding address at move-out, and a landlord should request one in writing and document when it arrives, because that date starts the three-week deadline.
Does Minnesota require a separate account for security deposits?
No. Minnesota does not require a landlord to hold security deposits in a separate escrow account, though keeping deposits segregated is a sound accounting practice. What the law does require is that the landlord pay one percent simple annual interest on the deposit regardless of where it is held, and account for it at move-out under Minnesota Statutes section 504B.178.
Can a Minnesota tenant use the security deposit as last month’s rent?
No. Minnesota Statutes section 504B.178 bars a tenant from unilaterally withholding the last month’s rent on the theory that the deposit covers it, and a tenant who does so can face additional damages. A tenant who simply stops paying and points to the deposit is treated as in default and can face an eviction action. At move-out the landlord may apply the deposit to any unpaid rent. For the demand process, see our guide on dealing with a non-paying tenant.
Where do Minnesota security deposit disputes get resolved?
Most Minnesota deposit disputes are decided in conciliation court, the state’s small-claims forum designed to be used without a lawyer. As of 2026, the conciliation court limit is twenty thousand dollars, raised from fifteen thousand effective August first, 2024, which comfortably covers a deposit claim plus the punitive damages. Verify the current limit, which the Legislature adjusts over time.
