LANDLORD GUIDE ยท WISCONSIN
Reviewed November 13, 2026
For an existing private residential tenancy. Fixed-term changes, assisted housing, mobile-home spaces and required local forms need a separate review. This guide explains selected rules; it is not a coverage determination or legal advice for a particular property.
The 28-day rule needs the right label
Wisconsin DATCP explains a 28-day written-notice rule for ending a month-to-month tenancy. That termination rule is not a separate statute approving every proposed rent increase. Review the lease's change and renewal terms and obtain any required agreement.
The tool uses 28 days plus a full future rent cycle as a planning floor. If the lease promises 60 days, follow that longer promise. A fixed-term lease remains fixed even if payments are collected monthly; inspect an applicable adjustment clause or address a later renewal.
Renewals and charge changes deserve a complete review
Check whether the lease renews automatically and when notice is required to change its terms. Do not assume a rent letter can cure a missed contractual renewal deadline. Keep the relevant clause with the proposed change.
Record rent, mandatory recurring charges and included utilities before and after the proposal. If a new fee or service obligation is involved, describe it appropriately and do not leave the unchanged-terms sentence misleading. Restricted or assisted housing needs the applicable program process.
Example: 28 days is not always the answer
A monthly agreement requires 45 days' notice of changed rent. A proposal for $1,260 instead of $1,200 is delivered 30 days before the intended start. The $60 or 5% arithmetic is correct, but the agreement's 45-day requirement still matters. Move to a later eligible cycle and document any required consent.
Before updating collections
Keep the current agreement, renewal correspondence, signed final proposal and delivery proof. A tenant's receipt acknowledgment should not be mislabeled as agreement to new terms. Resolve date or amount errors before charging the difference. Respond to repairs independently and use the appropriate separate notice and court process for any possession issue. This form is meant to continue an ordinary monthly tenancy.
Official sources and updates
Dated caps apply only to the periods stated. Check the official sources before preparing a later increase.
