Sacramento County ban on home “major auto repair”

if there is a harbor nearby? go dump some tea in it...this is a free country! I have 8 cars total in my driveway and drive at my outbuilding in rear. all are plated run and drive except one 65 barracuda parts car. I had code enforcement tell me I was in violation and could not have that many cars or work on them outside. "I was lowering their property values." I told him to bring me an appraisal before and after the cars with an appraisers note that my cars made their houses less valuable. That was about a year ago. Its been what I consider almost a national past time for a father and son to build hot rods together in this country indoors or outdoors. Nobody ever told George Washington or Alexander Hamilton how many horses they could have.
More power to ya, if you can insure 8 cars, pay registration on them, and drive them.
Then you're a lucky man, no issues with that, what so ever.
You must have a large driveway, if you can have something like that in your neighborhood.
How close are houses from one another, in your part of the world?
But in your case too, your code enforcement, might be keeping a eye out for you.
So keep it legal, and under their radar, would seem to be appropriate.
