In fact, this is a very thoughtful thing, because there are many such things now. As we all know, installing elevators on floors can be said to be a good thing for some residents on high floors, but it may not be a good thing for low floors.
However, it should be noted here that the elevator fees charged for each floor are different. The elevator fee at the top is naturally the most, and the lowest is the residents at the bottom. But now the elevator fees charged by many communities are not charged according to this standard, so once someone does not charge elevator fees according to this rule, they can actually complain.
Of course, for old houses, whether to install elevators actually needs to be negotiated with all residents in advance.
Therefore, once there is something that infringes on their own interests, they have not discussed it with themselves in advance. In fact, the owners are qualified to complain to the relevant departments.
