Can my landlord raise rent without notice in Wisconsin?

Quick answer

No. Wisconsin requires at least 28 days' written notice before a rent increase can start. If no notice was delivered, the new amount is generally not owed.

Step-by-step answer

  1. Step 1

    What 'no notice' actually looks like

    A missing notice can mean a text with no letter, a verbal comment, an increase applied by surprise on a new invoice, or a paper slipped under the door with fewer than 28 days before the new rent starts. Any of those falls short of Wisconsin's written-notice rule.

  2. Step 2

    How to respond

    Keep paying the current rent. Send a short written message to your landlord that says you didn't receive proper 28-day written notice under Wisconsin law and will continue to pay the current amount until a valid notice is delivered. Save copies of everything.

Plain English recap

No. Wisconsin requires at least 28 days' written notice before a rent increase can start. If no notice was delivered, the new amount is generally not owed.
