The law in plain English
Return deadline
Under Mich. Comp. Laws Sections 554.602 to 554.616, the deposit response usually has to be sent within 30 days of the move-out timeline described by the state rule.
Required notice
Michigan generally requires the landlord to mail an itemized damage list within 30 days, and the tenant should preserve proof of the forwarding address used.
This dispute type
Pet-related deposit disputes usually turn on proof. In Michigan, landlords still need to handle the refund and deduction notice correctly, and renters usually ask whether the charge reflects actual damage or just the landlord's assumption that pets always create extra cost.
Penalty leverage
If the withholding was wrongful or in bad faith, the exposure allowed under the statute is: You can recover double the amount of the deposit retained, plus attorney's fees and court costs
