Security Deposit Return in Michigan: The 4-Day Catch

A Michigan landlord has 30 days to send you an itemized list of deductions and whatever is left of your deposit. But before that clock matters, you have one of your own: 4 days from the end of your occupancy to give the landlord a written address where they can reach you.

Miss those four days and, under MCL § 554.611, the landlord is relieved of the duty to send you the itemized notice at all. You do not lose the deposit — your claim survives — but you lose the mechanism that forces them to justify what they kept.

The four days almost nobody counts

Four days is short enough that it is gone before most people have unpacked. The statute asks for written notice, sent to the address the landlord gave you under MCL § 554.603, of an address at which you can receive communications about the deposit.

Send it the day you hand back the keys. An email or a letter is fine as long as it is written and you can show you sent it. It costs nothing and it keeps the itemized-notice duty alive, which is the thing that makes a landlord explain a deduction instead of simply making one.

If you have already missed it, you are not without options. The statute is explicit that failing to give the address does not prejudice your later claim for the deposit — you can still ask for it and still sue for it. What you have lost is the automatic paperwork, so put your request in writing and ask for the itemization anyway.

The cap includes the pet deposit

Michigan caps the deposit at one and a half months’ rent, and a pet deposit counts inside that limit rather than sitting on top of it. So rent of $1,400 means a ceiling of $2,100 for everything combined. A landlord charging $2,100 plus a $400 pet deposit is over the line. Service animals and emotional support animals cannot be charged a pet deposit at all.

Where your money is supposed to be

The deposit has to sit with a regulated financial institution, or the landlord has to post a surety bond for it. Within 14 days of your moving in they owed you a written notice naming the institution and its address. If you never got that letter, mention it — a landlord who skipped the first duty often skipped the others.

The 30 days have passed

1. Check first whether you gave the written address, and when. That decides which duties the landlord still owed you.
2. Send one written demand naming MCL § 554.609, the date the 30 days expired, and the amount. Send it so you can prove delivery.
3. State the penalty: twice the amount wrongfully withheld. That figure changes how a landlord reads the letter.
4. Small claims is the normal route for a deposit, and no lawyer is needed to file.

What can legitimately be deducted

Unpaid rent, unpaid utilities you were responsible for, and damage past normal wear and tear. Not wear: minor scuffs, faded paint, worn carpet, light scratches on floors or counters. Michigan is explicit that ordinary wear is not deductible, so a list of small cosmetic items dressed up as damage is worth challenging line by line.

What your lease controls

Not the cap, not the 30 days, not your 4-day notice and not the bank disclosure — all statutory. A lease calling the deposit non-refundable, or charging a “move-out fee” that functions as a deposit, does not change what the statute requires.

When this needs a lawyer

Rarely for a deposit this size. Get advice if the landlord is claiming damages far beyond the deposit, if there is a disputed rent counterclaim, or if you missed the 4-day notice and the landlord is treating that as the end of the matter — it is not, and it helps to have someone say so in a letter. Michigan legal aid offices deal with this constantly.
