October 10 Move-In: Detroit / Ann Arbor ($1,650/month)
Consider a resident leasing an apartment in Detroit, Ann Arbor, or Grand Rapids with a monthly rent of $1,650.00 and move-in on October 10th. In October's 31-day duration, the tenant occupies the property for 22 days (October 10 through October 31 inclusive).
| Calculation Method | Daily Rate Formula | Daily Rate | Occupied Days | Prorated Rent Due |
|---|---|---|---|---|
| Actual Days Method31 Days in October | $1,650 ÷ 31 | $53.23 | 22 | $1,170.97 |
| 30-Day Month MethodStandard 30 Divisor | $1,650 ÷ 30 | $55.00 | 22 | $1,210.00 |
| 365-Day Annual Method($1,650 × 12) ÷ 365 | $19,800 ÷ 365 | $54.25 | 22 | $1,193.42 |
Method Comparison Note
In October (31 days), the actual-days method totals $1,170.97, which is $39.03 less than the 30-day month calculation ($1,210.00). In Michigan, most standard leases incorporate the actual calendar days of the initial month.
Michigan Landlord-Tenant Relationships Act (MCL 554.601 to 554.616)
Michigan security deposits are strictly governed by the Landlord and Tenant Relationships Act (Public Act 348 of 1972). The law establishes precise step-by-step procedures for collecting, holding, and returning deposits.
1.5 Months' Rent Cap
Under MCL 554.602, a security deposit cannot exceed one and one-half (1.5) times the monthly rent.
14-Day Bank Notice
The landlord must notify the tenant in writing within 14 days of move-in stating where the deposit is held in a regulated financial institution (MCL 554.603).
30-Day Itemized Notice
Landlords must mail an itemized list of claimed damages with estimated repair costs and balance refund within 30 days of move-out (MCL 554.609).
1.5-Month Statutory Cap, Regulated Escrow & 14-Day Written Notice
Statutory Maximum (MCL 554.602): The total security deposit collected cannot exceed 1.5 times the monthly rent. If monthly rent is $1,650, the maximum deposit is $2,475. This cap encompasses all refundable fees, including pet deposits.
Regulated Banking Escrow (MCL 554.604): Deposits must be deposited in a regulated financial institution in Michigan. Alternatively, the landlord may post a cash bond or surety bond with the Michigan Secretary of State.
14-Day Notice with Statutory Warning (MCL 554.603): Within 14 calendar days of occupancy, the landlord must provide written notice stating the name and address of the financial institution or surety company. The notice must contain the statutory warning regarding the tenant's obligation to provide a forwarding address within 4 days of vacating.
Mandatory Move-In Inventory Checklists (MCL 554.608)
Michigan requires an inventory checklist at the inception of tenancy to prevent arbitrary damage claims at move-out:
Two Blank Checklists at Move-In: The landlord must deliver two blank inventory checklists to the tenant upon taking possession, noting the current condition of carpet, walls, appliances, and fixtures.
7-Day Tenant Return Window: The tenant has 7 calendar days to inspect the rental unit, record any existing damage or defects, and return one completed copy to the landlord.
Baseline for Move-Out: At move-out, the landlord must assess damages against the baseline documented on the move-in checklist. Use our move-in move-out checklist to preserve a photographic record.
The Michigan 4 / 30 / 7 / 45-Day Two-Way Return Procedure
Michigan operates a unique mutual-response procedure for security deposit returns that requires strict adherence to four chronological statutory milestones:
Step 1: Tenant 4-Day Forwarding Notice (MCL 554.611)
The tenant must notify the landlord in writing of a forwarding address within 4 calendar days after vacating the rental unit.
Step 2: Landlord 30-Day Itemized Notice (MCL 554.609)
Within 30 calendar days of move-out, the landlord must mail an itemized list of claimed damages with estimated repair costs and a refund check for any remaining balance.
Step 3: Tenant 7-Day Dispute Notice (MCL 554.612)
If the tenant disagrees with any claimed deductions, they must respond in writing via mail within 7 calendar days detailing their objections.
Step 4: Landlord 45-Day Lawsuit Deadline (MCL 554.613)
If deductions remain disputed, the landlord MUST file a court lawsuit within 45 days of move-out to obtain a judgment, or return the disputed money in full.
Mandatory 45-Day Lawsuit Requirement & Double-Deposit Penalty (MCL 554.613)
Unlike most states where landlords can simply keep disputed deductions until the tenant sues them, Michigan shifts the burden of suing onto the landlord:
MCL 554.613(2) Waiver & Double Damages:
"Failure of the landlord to comply with the notice of damages requirement... shall constitute an agreement by the landlord that no damages are due and he shall immediately remit to the tenant the total deposit. Failure of the landlord to file court proceedings within 45 days shall constitute willful retention... and shall entitle the tenant to an award of double the amount of the security deposit."
If your landlord missed the 30-day notice or failed to file suit within 45 days of move-out, they forfeit all claims. Send our statutory security deposit return letter to demand your refund.
Month-to-Month Termination & Truth in Renting Act (MCL 554.631)
Month-to-Month Termination (MCL 554.134(1)): To terminate a periodic month-to-month tenancy at will, either party must serve at least one full calendar month's written notice before the end of the monthly period. Draft your notice using our move-out notice letter.
Truth in Renting Act (MCL 554.631 et seq.): Michigan leases cannot contain provisions that waive tenant statutory rights under the Security Deposit Act, accelerate rent without default, or require tenants to waive notice of court proceedings. Any unlawful clause is void and can subject the landlord to statutory penalties.
Local Rental Dynamics: Detroit, Ann Arbor & Grand Rapids
Detroit & Wayne County
36th District Court handles heavy landlord-tenant dockets. City rental ordinances require landlord certificates of compliance before collecting rent.
Ann Arbor (U of M)
University of Michigan leases turn over on August/September schedules. Ann Arbor's Early Leasing Ordinance restricts how early landlords can show occupied units.
Grand Rapids & Lansing
Kent and Ingham counties enforce strict inventory checklist rules. Mid-month move-ins typically utilize calendar actual days for transparent proration.
Michigan Proration Frequently Asked Questions
How is prorated rent calculated in Michigan?
Michigan statutory law does not mandate a single proration formula. The signed lease agreement determines the calculation method, with most housing providers using the actual number of calendar days in the month, while others utilize a 30-day banker's divisor.
What is the maximum security deposit allowed in Michigan?
Under MCL 554.602, a Michigan landlord cannot demand or receive a security deposit exceeding one and one-half (1.5) times the monthly rent. This cap encompasses all refundable deposits, including pet deposits.
What is the 14-day notice requirement under MCL 554.603?
Within 14 calendar days of taking possession, the landlord must provide written notice to the tenant stating the name and address of the financial institution or surety company where the deposit is held, along with statutory language advising the tenant of their obligation to provide a forwarding address within 4 days of vacating.
What is the inventory checklist requirement in Michigan?
Under MCL 554.608, the landlord must provide the tenant with two blank inventory checklists at move-in. The tenant has 7 calendar days to complete and return one checklist noting preexisting defects. This checklist serves as the baseline for assessing any move-out damage claims.
Why must a Michigan tenant provide a forwarding address within 4 days?
Under MCL 554.611, the tenant must notify the landlord in writing of a forwarding address within 4 calendar days after vacating. Failing to provide this notice relieves the landlord of the duty to send an itemized list of damages, though it does not eliminate the landlord's duty to return the deposit.
What is the 45-day lawsuit requirement under MCL 554.613?
Under MCL 554.613, if a tenant disputes the landlord's 30-day itemized damage notice in writing within 7 days, the landlord MUST file a court action within 45 calendar days of move-out to obtain a judgment for the claimed damages. Failure to file court proceedings within 45 days constitutes a waiver of all damages and entitles the tenant to double the deposit.
How much notice is required to terminate a month-to-month lease in Michigan?
Under MCL 554.134(1), either party may terminate a periodic month-to-month tenancy at will by providing at least one full calendar month's written notice.
