Is it necessary to discuss with the property when opening the window?

First of all, the self-sealing window on the balcony of the residential area is legal, because the self-sealing window belongs to the exclusive right of the owner's building ownership, and the owner's ownership of its exclusive part can be freely exercised without interference from others. But first, you need to communicate with the property and seal the windows.

Secondly, according to the provisions of the law and the agreement of the property management service convention, the owners should cooperate to fulfill the relevant obligations of the property service contract in order to safeguard the interests of the owners in using, maintaining and managing the property. Especially when some owners close balcony windows without authorization, the owners' committee issues an announcement to all owners of the community, and all owners' representatives vote to decide whether to close the landscape balcony.

Finally, in the case that all owners are not allowed to close balcony windows in the referendum, the behavior of some owners closing balcony windows without authorization should be against the interests of all owners.
