Wisconsin uses a patchwork system to regulate mobile home communities that often forces communities like Plymouth to act alone when a park owner won’t make repairs to houses with malfunctioning plumbing, broken heating systems and mold-covered walls, a Gannett Wisconsin Media investigation has found.
Even though the state has the authority to respond to residents’ complaints and to take away park owners’ licenses, responsibility for oversight is spread between two agencies. The results can be long delays in responding, frustration for residents whose complaints bounce around in state bureaucracy and unchecked health risks for tenants, many of whom are elderly and poor.
