Key Michigan Statutory Nuances & Documentation Rules
- 4-Day Tenant Address Notification Rule (MCL 554.611): The tenant must notify the landlord in writing of a forwarding address within 4 days after move-out; failure to do so relieves the landlord of sending the 30-day itemized notice (though not from returning unspent funds).
- 7-Day Tenant Objection Notice (MCL 554.612): When the landlord sends the 30-day itemized notice, the tenant has 7 calendar days after receipt to respond in writing disputing the listed repair deductions.
- 45-Day Lawsuit Requirement (MCL 554.613): If the tenant disputes the deductions within 7 days, the landlord MUST file a formal court action within 45 days of move-out to retain disputed funds; failure to sue automatically forfeits the claim.
- Inventory Checklists at Move-In and Move-Out (MCL 554.608): Landlords must provide two blank inventory checklists at move-in; deductions for damages are prohibited if the landlord failed to provide the initial checklist.
Grand Rapids Rental Move-Out with Disputed Deductions
A tenant vacates a Grand Rapids apartment on July 15, 2026 and provides a forwarding address within 4 days. Under MCL 554.609, the landlord has 30 days (until August 14, 2026) to mail an itemized damage list. If the tenant disputes the $900 damage deduction within 7 days and the landlord does not file a court claim within 45 days of move-out (by August 29, 2026), MCL 554.613 requires the landlord to refund double the deposit retained ($1,800) in Michigan District Court Small Claims Division (limit $7,000).

How long does a Michigan landlord have to return a security deposit?
Under Michigan Compiled Laws (MCL) § 554.609, the landlord must mail an itemized list of damages, estimated costs, and any remaining balance within 30 calendar days after the tenant terminates occupancy.
What is the 4-day forwarding address rule in Michigan?
Under MCL 554.611, the tenant must notify the landlord of a forwarding address in writing within 4 days after moving out. Failing to provide this address excuses the landlord from mailing the 30-day notice, but does not waive the tenant's right to an eventual refund.

Under MCL 554.602, a security deposit cannot exceed one and one-half (1.5) times the monthly rent.
When is a Michigan landlord liable for double the security deposit?
Under MCL 554.613, if a landlord fails to send the itemized damage statement within 30 days, or fails to file a court action within 45 days after a tenant timely disputes deductions, the landlord must pay the tenant double the amount of the security deposit retained.
