I got a noticelike that a couple years ago. Our house was brand new, as was the asphalt driveway. The company that poured the asphalt said not to park anything on it long term for the first six months--but we needed a place to park our boat. The lot next to ours was open, so we contacted the owner, and asked if they'd mind if we parked the boat there for the summer. They said "go ahead--no problem".
A few months later (June), we got a notice from the city. Someone had complained, and the city cited us for parking a vehicle on an unimproved area of our lot.
We responded to the city employee who wrote the citation, who was some new low-level person in the department, that it's not on an unimproved area of our lot--in fact, it's not on our lot at all. It's on the neighboring lot, with the lot owner's permission, and that because that lot wasn't developed yet, the rule didn't apply, per the city's own ordinances. (Which wasn't entirely true--the lot had been developed, but no construction had started on it, so that development wasn't obvious to the naked eye.) Further, the boat would only be there until late September, when the boat gets put into storage for the winter season, and next year it would be on our asphalt driveway.
He responded that that sounded reasonable--but that he wasn't sure that was appropriate, and that he'd have to check with his boss to see if we were OK. He also informed us that the citation was triggered by a citizen complaint. So we waited to hear back from him. And waited. And waited. And heard nothing. So we assumed the matter had been dropped.
On September 22, we got the citation back, saying that we were wrong, and that we had two weeks to move our boat to avoid a fine. So we put it into storage, and that was that.
About a week later, through a friend of a friend of a friend who works at the city, we found out that this newbie who had cited us hadn't taken it to his boss at all. He had realized that what we were doing was perfectly within the spirit of the rules, regardless of the actual letter of the rules, and knew we were in the process of developing an appropriate long-term storage space, so he decided to stick the whole thing in his drawer until mid-September, knowing we had indicated we would be putting the boat in storage then. At which point he re-filed the citation, whose requirements we were easily able to meet. We were satisfied, the citizen was satisfied, his supervisor was satisfied, all was well.
I have to say it was one of the most impressive actions I've ever seen from any city government employee, anywhere.
