My cousin had a small restaurant, and one of the reasons he gave up was complying with all kinds of regulations. There was always some small detail that was wrong, and he typically did not get fined, he was just told to fix it before the next review. But it took a lot of his time. It was usually some stupid thing, such as painting the walls incorrectly, or using a wrong kind of screw on the roof, i.e. not even related to the food.
Also, one of the reasons it is difficult to build small kindergartens (like for 10 kids total) is that they are required to have a kitchen, which is required to have a certain area and inventory, which at this scale becomes the most expensive part of the kindergarten. But if you invite guests to your home, cooking for 10 people in your kitchen is easy, even if would completely fail the kindergarten regulations.
