P.M.
I know you resolved your issue but I thought I would mention that in our neighborhood we have an elderly, retired couple that made it their 'hobby' to drive the area and report code violations----they called the city so much that the city will no longer respond when they call.
I have found it very helpful to read the various codes. I happen to live in OP where there are rules about everything --- including that the city workers can come into your backyard to look for code violations. (They can have access to the entire yard and if something is visible to any of the neighbors you have to fix/move etc)
Some of my neighbors wrote me a 'nasty' note ---and then said they were giving me a chance to clean it before they called the city...Well I don't know when they mailed the note b/c I got the note on a Monday and got the letter from the city on Tues. (So they didn't wait at all to call us in) On that visit from the city no fewer than 5 houses got 'written up'-- including one neighbor who was cited for having their trailer TWO INCHES too FAR forward in their driveway. (A number of these neighbors decided that they were being harassed -- and the city worker who used to go through our neighborhood has been 'reassigned'....KOW it has been over a year since I heard of any of our neighbors getting written up.
