Michigan’s Landlord and Tenant Relationships Act (Act 348 of 1972), which took effect on April 1, 1973, dictates exactly how much money a landlord can demand upfront and rigorously governs how those funds must be managed and returned.
Failing to adhere to Michigan's highly specific security deposit timeline can result in the landlord forfeiting the right to keep any of the deposit to cover damages under MCL 554.609.
The Maximum Deposit Limit
Michigan law is exceptionally specific regarding the maximum allowable security deposit for a residential tenancy.
A landlord may not charge a security deposit that exceeds 1.5 times the monthly rent.
The Definition of "Security Deposit" in Michigan: The state considers any upfront fee that the landlord intends to use to protect against nonpayment of rent or damage to the property as part of the security deposit.
- You cannot charge 1.5 months' rent as a deposit and an additional $500 "pet deposit," as this would violate the statutory cap.
- The first month's rent is not considered part of the security deposit.
- Non-refundable "cleaning fees" or "application fees" are generally not classified as security deposits, provided they are explicitly designated as strictly non-refundable and are not used to cover damages.
Managing the Funds (The Notice of Location)
Unlike landlords in many other states who can simply deposit funds into their operating account, Michigan landlords must secure the tenant's deposit. The landlord must either:
- Deposit the money in a regulated financial institution (like a bank or credit union).
- Post a cash bond or surety bond with the Michigan Secretary of State.
The 14-Day Notice: Within 14 days of the tenant taking possession of the property, the landlord must provide the tenant with written notification of the name and address of the financial institution holding the deposit, and inform the tenant of their obligation to provide a forwarding address upon moving out.
The Inventory Checklist
You cannot collect a security deposit in Michigan without providing an Inventory Checklist.
At the time the tenant moves in, the landlord must provide two copies of a blank inventory checklist detailing every room in the unit. The tenant has 7 days to review the property condition, mark any pre-existing damages, and return one signed copy to the landlord.
Without this checklist, a landlord has virtually no standing to claim the tenant caused damage at the end of the lease.
The 30-Day Return Timeline
The timeline for returning a security deposit in Michigan after the tenant vacates is incredibly rigid.
- Within 4 Days: The tenant must provide the landlord with a forwarding address in writing.
- Within 30 Days: If the tenant provided a forwarding address, the landlord must return the full sequence deposit, OR return the remaining balance accompanied by an itemized list of damages. This list must include the estimated or actual cost of each repair.
- The 7-Day Dispute Window: The notice must state: "You must respond to this notice by mail within 7 days after receipt of same, otherwise you will forfeit the amount claimed for damages."
- The 45-Day Court Deadline: If the tenant responds within 7 days disputing the landlord's deductions, the landlord must file a lawsuit in small claims court within 45 days of the tenant's move-out date to legally keep the disputed amount. If the landlord fails to sue within 45 days, they must return the disputed funds to the tenant, even if the tenant severely damaged the property.
