In Wisconsin how much can a landlord raise the rent in one month?

There is no statewide regulation in Wisconsin that limits the amount a landlord can raise rent by in a month. Rent increases are negotiated between landlords and tenants, and the terms of the lease agreement dictate how much notice must be given before a rent increase can take effect.

Wisconsin law does require that landlords provide a minimum of 28 days' notice of a rent increase, except in the following cases:

* If the rent is for a month-to-month tenancy, the landlord can give 14 days' notice.

* If the rent is for a lease that is less than one year, the landlord can give 60 days' notice.

* If the rent increase is less than 10%, the landlord can give 14 days' notice.

In addition, Wisconsin law prohibits landlords from retaliating against tenants who exercise their legal rights, such as complaining about housing conditions or joining a tenants' association. If a tenant believes that their landlord is retaliating against them, they can file a complaint with the Wisconsin Department of Safety and Professional Services (DSPS).
