Wisconsin has no rent control and no dedicated rent-increase notice law. Because an increase changes the terms of a periodic tenancy, it takes effect only at a new rental period, so a landlord must use the termination notice in Wis. Stat. Sec. 704.19. For month-to-month that means at least 28 days' written notice.
No Wisconsin statute caps residential rent or sets a stand-alone rent-increase notice period. A landlord cannot raise rent during a fixed-term lease unless the lease allows it. To raise rent on a month-to-month tenancy, the landlord must end the existing periodic tenancy and offer new terms, which triggers Wis. Stat. Sec. 704.19: 'at least 28 days' notice must be given except' where rent is payable on a basis less than monthly. The de facto rule is therefore 28 days' written notice before the increase. State law preempts most local rent control, so cities generally cannot impose stricter caps. Wis. Admin. Code ATCP 134 governs disclosures but adds no rent-increase notice requirement.
No specific statutory penalty for the increase itself. A rent increase imposed mid-fixed-term without lease authority, or on a month-to-month tenancy with less than the 28-day notice required to change terms under Sec. 704.19, is unenforceable for that period.
