The property is not allowed to seal the balcony, right?

There are laws and regulations. Whether the balcony is closed or not is decided in the planning and design of commercial housing for approval. Individuals and developers are not allowed to change the closure method without authorization. One is related to the calculation of the area of the house, and the other is related to safety. Open balcony and closed balcony are not included in the housing area, and the bearing capacity of open balcony and closed balcony is different in design. Originally an open balcony, it was changed into a closed balcony, and the modified material itself is very weighty. Moreover, the use of the balcony often changes after it is closed, and many people will pile things on the balcony, which brings great security risks.
