Do I have any rightss against code enforcement from city ordinances?

Unfortunately this is the never ending battle between neighbors. Your rights to use your property as you see fit Vs. Their rights to their view and property value. Nobody is absolutely right and nobody is absolutely wrong. Laws must be written in Black and White because no two people can agree on the shade of grey that's acceptable. I've found that there is no recourse you have against mandates. They tried the same thing with me. My car was fine, I just needed plates. The car didn't run at the time. To get plates I needed insurance and an emissions test. On a car that didn't run. There was no reasoning with these people in any way. I turned the car around so they couldn't see my plates without coming on my property. And they weren't allowed on my property. If your car can at least look like it runs and drives or may be made to appear like it runs and drives you may be able to get away with something along those lines.
