Is it legal to enlarge the umbrella on the terrace of the community?

It is illegal to enlarge the umbrella on the terrace of the community.

The ownership of the terrace on the second floor of the community belongs to all industries. Generally speaking, the balcony on the second floor is not written into the building area, so the actual property right belongs to the owner. But if it is clearly stated in the purchase contract, this is the ownership of the second floor.

In addition, in reality, the balcony of some communities can only be accessed by the owner's house on the second floor, so users on the second floor can use it if the property permits, so ownership is very important to the relationship between developers and properties.
