Property law of opening the back door of residential supermarket

According to your description, there are actually several aspects.

First, if the original design of the house has a back door, it can be opened, because people have not changed the facade and changed the use function of the house, which is allowed.

Second, since it is a door, supermarkets facing the street are generally fire doors. According to the national fire management regulations, fire exits must be kept open. You can report this problem to the fire department.

Third, if raising a dog bothers you and affects your daily life, you can ask the property management company to stop it according to the neighboring rights. If it doesn't work, you can go to the street or the court.
