Michigan security deposit law

What your landlord is legally required to do after you move out, how long they have, and what it costs them if they get it wrong.

Deadline to return

30 days

Governing statute

Mich. Comp. Laws § 554.609

The deadline

Under Mich. Comp. Laws § 554.609, a landlord in Michigan must return your security deposit — together with any required written itemization of deductions — within 30 days. Once that window closes without payment or a proper itemization, the landlord is in violation of the statute.

The tenant has 7 days to respond to the itemized list or forfeits the right to contest it. The landlord has 45 days after termination to file suit for disputed amounts or must return the balance.

What it costs your landlord

Under Mich. Comp. Laws § 554.613, a landlord who wrongfully withholds a deposit in Michigan may be liable for double the amount of the security deposit retained. That exposure is the reason a formal demand letter works: it is usually cheaper for a landlord to pay you than to argue about it.

How to get your deposit back in Michigan

1. Confirm the deadline has passed. Count from the day you moved out and returned possession. In Michigan that's 30 days.
2. Put your forwarding address in writing. In several states a landlord has no obligation until they have it, and having sent it protects your claim.
3. Gather your evidence. The lease, proof you paid the deposit, move-in and move-out photos, and any itemization they sent.
4. Send a written demand by certified mail. Cite Mich. Comp. Laws § 554.609, state the amount owed, and give a deadline to pay. Certified mail creates the delivery record a judge will want to see.
5. File in small claims if they ignore you.You don't need a lawyer. File in the county where the property is located.
