Security Deposit Return Deadline in Wisconsin

In Wisconsin, a landlord must return your security deposit within 21 days after move-out. Missing this deadline often forfeits the landlord's right to keep any portion of the deposit, and many Wisconsin tenants recover additional statutory damages for bad-faith withholding.

Wisconsin HOA Law

HOA fines and assessments in Wisconsin are governed by the Wisconsin Condominium Ownership Act (WIS. STAT. §703). This law generally requires written notice, an opportunity to be heard, and documented evidence before a fine becomes enforceable.

Wisconsin Utility Regulator

Utility billing disputes in Wisconsin fall under the Public Service Commission of Wisconsin (PSC) — psc.wi.gov. Your utility generally cannot disconnect service while a formal billing complaint is pending with the regulator.
