Michigan Security Deposit Demand Letter
M.C.L. § 554.611
30 days after move-out
2× the deposit amount (double the amount of the security deposit wrongfully withheld)
Michigan law is clear: under M.C.L. § 554.611, your landlord has exactly 30 days after you move out to either return your security deposit in full or send you an itemized written statement explaining every deduction. Miss that window, and the landlord loses their legal right to withhold any portion of the deposit.
A demand letter puts your landlord on formal notice that you know your rights under Michigan law and are prepared to act. It establishes the written record that small claims court — and your landlord's attorney — will want to see. Many landlords respond to a properly formatted demand letter simply because it signals you're serious and informed.
DemandFast generates a Michigan-specific demand letter that cites M.C.L. § 554.611 directly, states the exact return deadline that applied to your tenancy, and formally demands the return of your deposit, along with the statutory penalty of up to 2× the wrongfully withheld amount. The letter is formatted for certified mail — the delivery method courts and recipients expect — so you have proof of delivery when you need it.
If your landlord continues to ignore you after receiving the demand letter, your next step is to file a complaint with the Michigan Department of Attorney General or pursue your claim in Michigan small claims court, where the demand letter becomes part of your documented case.
