Is it illegal to seal the balcony with corridor?

Closed balcony is illegal construction, which is one of the key targets of the government, Planning and Natural Resources Bureau and Urban Management Comprehensive Administrative Law Enforcement Bureau. Closing the balcony not only changed the external window area of the original building, but also changed the facade. Therefore, closing the balcony is not only a family decoration project, but also requires the relevant management departments to declare administrative planning permission, construction drawing review, fire protection special review, construction permit, and five-party acceptance after completion. It is illegal to close the balcony without approval.

If you find that some neighbors in the community have closed balconies, you can not only contact the property to ban them, but also seek relief from urban management and government departments, or directly call 12345 to complain and report.
