Why can't you give them the brother's name and have them fine him?? Or, the person you bought the house from. You can't be held responsible for something that was there when you bought it. And, the Rubbermaid shed can't have a building permit. We have one. It's not a building. There are no plans. Sounds like they are related to someone in Code Enforcement, too. Talk to the neighborhood planning association. It should be in the covenants.
