Is it reasonable to change the north balcony into a kitchen property without refunding the decoration deposit?

Under normal circumstances, the original design purpose of the house cannot be changed.

This situation belongs to illegal decoration. Property companies have the obligation to inform and stop.

Property owners and users are not allowed to change the use, structure and appearance of housing facilities without authorization. In violation of regulations, the property management company has the right to stop, criticize and educate, order restitution and compensate for losses. Therefore, the owner cannot change the use of his property without authorization. If this is done, any owner can complain, and the property management company has the right to stop this behavior and demand restitution.

Decoration deposit is non-refundable, there should be an agreement. You can consult the property management department.

I hope to give you a reference.
