It really depends. Around here it's considered a pretty nice place to live, but there are still a lot people working on their cars. I've seen this one car in the neighborhood that seemed to perpetually be on jack stands on the same driveway. A lot of homeowners have converted their garages to workspaces so their cars are parked on the street or driveway, and some even use the driveway as workspaces. I don't think we have any specific ordinances that would prohibit it.
Having a car parking on the lawn would be another matter. I know someone (hint, hint) who is a professional mechanic and doesn't work at home as a side hustle. He told me that his dealership cut him off from buying parts at a discount, but he continued to go through other employees who he would help fix up their cars. He doesn't work there any more so he can't get in trouble for it now. His carport has a professional lift and everything. So far the local authorities haven't complained, even when he's got cars in the neighborhood parked more than the theoretical max time.
The most I've ever done was an oil change on my driveway. A few times I saw someone changing the oil parked on the street.
