Is it legal to hit the carport at the entrance of the underground parking lot in my house?

Illegal. That's an illegal building and it's not allowed. This fixed pattern needs to be recognized. In addition, there are so many people who call the wind when they go out of the wall, and there are hidden dangers in safety. In addition, this piece installed on the wall also damaged the firmness of the wall. Can negotiate with the parties (developers, property management companies, individual owners, government departments, etc.). Who infringes on the owner's rights and interests through the owners' committee to solve the problem that the owner's rights and interests are infringed.
