I'm the fifth floor, the top floor of Yangluo Tianqinwan Community, and I want to send it to the sixth floor. I want to open the skylight, but the property doesn't agree, so I can't change it without authorization. What should I do? You really can't move. It is not easy to open the window on the top floor, because it involves the waterproofing of the whole building. Because it is a whole, after you move, there is water leakage, and you can't afford it. Because once the water leaks, local maintenance will not work at all. Must be done on the whole roof. If such a problem occurs, the property can't afford it and needs to use the maintenance fund. Is a very troublesome thing.
