Return security deposit with itemized statement within 21 days of move-out. Wisconsin law (ATCP 134.06) requires delivering or mailing the deposit balance, less any properly withheld amounts, and a written statement explaining any withholding within 21 days after the tenancy ends, and noncompliance exposes the landlord to double damages plus attorney fees.
