> No, because working from home doesn't cause negative externalities imposed upon the neighbors - quite the other way around, the fact you're working from home reduces the impact of commuting. You didn't say anything about externalities, you was talking about ""running a commercial operation in a residential zone" which is same as musical lessons or any other work from home and honestly I don't even know why you care whether I repair my own car for free or helping friend or charging stranger, what does it have to do with (not) producing noise. I said I could understand noise/chemicals concerns, but if there is no noise and no leaking chemicals this ban makes no sense. Piano/musical lessons certainly cause noise emissions even outdoors, if you are direct neighbor, I don't see difference why they should not be blanket banned same as car repair. As I said this whole ban doesn't make sense, they should ban reaching certain noise level (which we have here in Europe) and then you can call police to investigate and fine and ban neighbor from doing so individually, but not making blanket ban on something just under assumption it will be noisy. > Gas-powered lawnmowers should be banned, and so should any form of leaf blowers, alone for environmental protection. Are lawnmowers and leaf blowers banned in Sacramento same sa car repair in own garage? I don't care about shoulda coulda woulda. If those are allowed, but at same time there is general ban on car repair, this ban can't stand in court if challenged, if they produce same noise, it's either both or none.
