Sacramento County ban on home “major auto repair”

I'm sure having junkers, next driveway over to you, on your street, in your neighborhood, would be allowed, tolerated, by your neighbors, or even you, in plain view for everyone to see.
You got lots of HOA restrictions, city, county, codes where you live.
That's why your where your at.
You prefer your hood, and chose to live there for reasons, and not having junk cars to bring down the property values of your place in the high rent district, of this town.

No HOAs where I am. NONE.
My area is sort of rural but I have cars and parts here. I keep everything tucked away though. As Crackedback wrote, if it is out of view from the street, move along. I like that.
My point on this matter is pretty clear:
If a person needs to do periodic maintenance on their own cars, why screw with them?
If a Hobbyist has a project car in his shop or behind a fence, why is that a problem ?
I personally have no problem with Jim Hemi71X doing his brake restorations in his garage. I suspect that he is responsible enough to be careful and not make an ecological disaster.
From what I have gathered, this legislation was primarily directed towards the growing trend of residential auto dismantling that results in spillage of oil, ATF, anti-freeze, A/C refrigerant, etc. I would agree that if this were the primary goal of this law, it is a reasonable idea. Auto wreckers are required to properly contain all these fluids and they are inspected periodically. Some guy in a rented house may not care about the impact of dumping all that crap in a hole in the yard.
Now, it does seem that the law is in keeping with almost every other BS Law that goes through our over regulated state: It throws the baby out with the bathwater. It reminds me of the strict teachers that make the whole class stay late because of one bad student.
Why did they not draw better law that allows periodic, routine maintenance ? Why the heavy handed approach?
