Minnesota generally requires the landlord to return the security deposit with interest or send a written statement explaining the specific reason for withholding within three weeks after the tenancy ends and after the landlord receives the tenant's mailing address or delivery instructions.
Minnesota is not just a generic 21-day state. The mailing address or delivery-instruction trigger matters.
Ordinary Minnesota timing chain
- The tenancy ends.
- The tenant gives the landlord a mailing address or delivery instructions.
- The landlord has three weeks to return the deposit with interest or send a written statement showing the specific reason for withholding.
What the landlord must send
If the landlord keeps any amount, Minnesota requires a written statement showing the specific reason for the withholding. If the landlord returns the deposit, the return should include required interest.
Mailing can matter
Sometimes the deadline question is not only when you received the refund or written statement. Minnesota allows the landlord to satisfy the timing requirement by placing the refund or written statement in first-class mail within the deadline, with postage prepaid, a return address, and the correct address based on your mailing address or delivery instructions. Save envelopes, postmarks, tracking records, and messages.
That is why your own proof matters. If you can show when the tenancy ended, when the landlord received your address or delivery instructions, and what was or was not mailed back, the deadline dispute is much cleaner.
Special condemnation situation
A separate 5-day rule can apply when a tenant leaves because the building or dwelling was legally condemned, if the condemnation was not caused by the tenant's willful, malicious, or irresponsible conduct. That is a special situation, not the ordinary path for most deposit disputes, and it is not the same as every repair problem or code complaint.
If you are unsure which rule applies
Most renters should start with the ordinary three-week rule, then look for facts that change the analysis. If the rental was legally condemned, preserve the condemnation notice, move-out date, and proof that the landlord received your mailing address or delivery instructions.
Why the trigger gives you leverage
The mailing address or delivery-instruction step is not just a technical detail. It helps show when Minnesota's clean deadline path started. Once that record is clear, a missing refund, missing interest, vague written statement, or unsupported deduction is easier to challenge in writing.
