If you are a public official, it’s usually not a good idea to send to your constituents a letter threatening them with sign code enforcement because they put up signs criticizing your official actions. And don’t have another public official do it for you, either, such as a selectman having the building code inspector do it.
If you’re thinking about trying to regulate a sign because of what it says, you may want to think twice.
