Code enforcement officers have a tendency to get a burr under their saddle. I had one single me out even though he never once saw me with a wrench in my hand (he was convinced that I was running an auto repair business). Apparently his final act got him fired, though. I would catch him driving through our cul de sac daily when I would be home for lunch (in my work van). I followed him one day so he called parking services on our perpendicular parking (not legal, but common at the back of a cul de sac). Sacramento decided some time back to make working on cars illegal at your home. Not sure what the solution is beyond better representation...
