(a) Increase rent.
(b) Decrease services.
(c) Bring an action for possession of the premises.
(d) Refuse to renew a rental agreement.

(2) Authorizes the eviction or exclusion of a tenant from the premises, other than by judicial eviction procedures as provided under ch. 799, Stats.
(3) Provides for an acceleration of rent payments in the event of tenant default or breach of obligations under the rental agreement, or otherwise waives the landlord’s obligation to mitigate damages as provided under s. 704.29, Stats.
(4) Requires payment by the tenant of attorney fees or costs incurred by the landlord in any legal action or dispute arising under the rental agreement. This subsection does not prevent a landlord or tenant from recovering costs or attorney fees under a court order under ch. 799 or 814, Stats.
(5) Authorizes the landlord or an agent of the landlord to confess judgment against the tenant in any action arising under the rental agreement.

(7) Imposes liability on a tenant for any of the following:
(a) Personal injury arising from causes clearly beyond the tenant’s control.

This paragraph does not affect ordinary maintenance obligations of a tenant under s. 704.07, Stats., or of a tenant under a rental agreement or other written agreement between the landlord and the tenant.
(8) Waives any statutory or other legal obligation on the part of the landlord to deliver the premises in a fit or habitable condition, or to maintain the premises during the tenant’s tenancy.
(9) Allows the landlord to terminate the tenancy of a tenant based solely on the commission of a crime in or on the rental property if the tenant, or someone who lawfully resides with the tenant, is a victim, as defined in s. 950.02 (4), Stats., of that crime.
(10) Allows the landlord to terminate the tenancy of a tenant for a crime committed in relation to the rental property and the rental agreement does not include the notice required under s. 704.14, Stats.
