Minnesota Security Deposit Small Claims: How to Sue Your Landlord

Your landlord had 21 days to return your security deposit or send a written explanation of what they withheld and why. If that deadline passed and you have heard nothing — or you got a deduction list that does not add up — Minnesota law gives you a clear path through Conciliation Court.

The 21-Day Rule Under § 504B.178

Minnesota Statutes § 504B.178, Subdivision 3, requires landlords to return a tenant's security deposit with interest or provide a written statement showing the specific reason for withholding within three weeks after the tenancy ends and the landlord receives the tenant's mailing address or delivery instructions.

If the landlord misses that 21-day window, the consequences are automatic. You can claim:

• The full deposit amount (or the wrongfully withheld portion)
• A statutory penalty equal to the amount wrongfully withheld — effectively doubling your recovery
• Up to $500 in bad-faith retention damages under Subdivision 7, if the landlord acted in bad faith

The landlord must also pay 1% simple annual interest on the deposit. Interest runs from the first day of the month after you paid the full deposit through the last day of the month in which the landlord in good faith returns it or provides the required statement, or through the date judgment is entered, whichever comes first. Interest under $1.00 is excluded.

If the building was legally condemned, the return deadline shortens to 5 days.

Where to File

You may bring a security-deposit claim in the county where the rental property is located or, at your option, in the county where the landlord resides. See § 491A.01, Subdivision 9, and § 504B.178, Subdivision 9.

Calculating Your Claim

Add up the pieces:

1. Unreturned deposit (or the portion withheld without justification)
2. Statutory penalty (equal to the wrongfully withheld amount)
3. Bad-faith damages (up to $500, if applicable)
4. Accrued 1% interest

The total must stay within the $20,000 Conciliation Court limit. For most security deposit disputes, this is not an issue — the typical claim range runs $500 to $4,000.

Filing the Claim

Complete Form CCT102 (Plaintiff's Statement of Claim and Summons) through Minnesota Guide & File or on paper. Name the landlord — or the property management company — using their exact legal name. If the landlord operates through an LLC, search the Minnesota Secretary of State portal to confirm the registered entity name and registered agent.

Pay the filing fee ($70–$80 depending on county). If your income is below 125% of the federal poverty level or you receive means-tested public assistance, you can apply for a fee waiver using Form CCT104.

Service depends on the claim amount. If your total claim (deposit + penalty + damages) is $2,500 or less, the court clerk handles service by first-class mail at no extra cost. If your claim exceeds $2,500, you must serve the landlord yourself via certified mail with restricted delivery or through a process server, then file Form CCT103 (Affidavit of Service) within 60 days.

Evidence That Matters

Judges in deposit cases look for documentation of the 21-day timeline:

• Your lease (shows the deposit amount and lease end date)
• Written forwarding address notice (letter, email, or text — with proof you sent it)
• Move-in and move-out photos (timestamped, showing the unit's condition)
• The landlord's withholding statement (if they sent one — highlight any vague or unsupported deductions)
• Calendar showing the 21-day deadline and when it passed
• Any communication with the landlord about the deposit

Bring three paper copies of your evidence. Submit and share all digital exhibits through MNDES at least three days before trial. If the landlord never sent a withholding statement at all, the deadline failure itself is your strongest evidence.

What to Expect at the Hearing

The judge will ask when the tenancy ended, whether you provided a forwarding address, whether the landlord returned the deposit within 21 days, and what the landlord's stated reasons for withholding were. If the landlord cannot produce a timely, itemized statement, the statutory penalty is straightforward.

Landlords sometimes argue the deductions were legitimate (cleaning, repairs beyond normal wear). Bring your move-in and move-out photos to counter this. Normal wear and tear is not a valid deduction under Minnesota law.

After You Win

If the judge rules in your favor, the judgment includes a 21-day automatic stay. If the landlord does not pay within that window or file for removal to District Court, you move into the collection phase.
