Tenant Retaliation Complaint Form
Tenant protection against retaliation
As a tenant in Sun Prairie, you have the right to contact the City of Sun Prairie and request that your housing provider address maintenance or safety concerns. Under Sun Prairie Municipal Code Section 9.18, housing providers are prohibited from retaliating against tenants for exercising these rights. While the law cannot prevent retaliation before it happens, once a retaliatory act has occurred, it may be considered a violation of city law.
IN ORDER TO FILE A RETALIATION COMPLAINT, YOU MUST HAVE ALREADY SUBMITTED A BUILDING CODE VIOLATION COMPLAINT TO THE CITY VIA REPORT A CONCERN
What is retaliation?
Retaliation occurs when a housing provider takes negative action against a tenant in response to the tenant exercising a legal right such as filing a complaint or requesting repairs. Examples of retaliation include:
- Refusing to renew your lease
- Filing for eviction
- Using harassment or intimidation (verbal or physical)
- Increasing rent or refusing rent payments without justification
- Reducing or eliminating services (e.g., laundry access, parking)
- Failing to complete agreed-upon repairs
- Shutting off or reducing essential utilities like water, electricity, or heat (always illegal)
- Imposing new or increased fees
- Taking any other action that could be reasonably seen as punishing a tenant for making a complaint
