What counts as valid notice

A valid rent-increase notice in Wisconsin is delivered in writing, states the new rent amount, states the date the new rent starts, and gives you at least 28 full days before that date. A text message or a hallway conversation is generally not enough on its own.

What to do if the notice was short

Keep the notice and the envelope (or a screenshot with a timestamp). Reply in writing that the notice does not meet Wisconsin's 28-day rule and that you'll continue to pay the current rent until a proper notice is delivered. A local tenant-rights group can help you draft the letter.
