The house is ready to be renovated, but there is no property in the community and the management is chaotic. How do I apply for a work permit? Pray for the great gods.

Generally speaking, the renovation of residential houses does not require any construction permit, as long as you do not destroy the structure of the house, that is, the beams and walls of the load-bearing part of the house (especially the walls adjacent to the external wall). Under normal circumstances, if there is property management, every household will be required to sign a decoration warranty agreement before renovation, but if there is no property management, there may be different ways. Specifically, you can ask the unit that should give you the key (usually the developer) what procedures are needed. If they have no other requirements, you can start decorating, but generally pay attention to no obvious noise after 2 1:30 in the evening, so as not to disturb the neighbors.
