How Wisconsin security deposits work
Wisconsin splits its security deposit rules between two places, and the important one is not the statute you would expect. The main withholding rule sits in Wis. Stat. 704.28, but the 21-day return deadline and the itemization requirement live in the administrative code at ATCP 134.06, a consumer protection regulation. A landlord must return your deposit, minus any lawful deductions, within 21 days after your lease ends and you move out, and must include a written statement listing every charge. There is no cap on how much a landlord can require up front. If a landlord breaks these rules, you can sue under Wis. Stat. 100.20(5) for double the amount wrongfully withheld plus your court costs and attorney fees. A landlord can only keep money for unpaid rent, tenant damage beyond normal wear and tear, and a few specific unpaid charges like utilities.
