The property right of the relocated basement can be sold to the relocated households.

The property in the underground storage room of resettlement houses is generally not for sale. This involves changing the nature of the house, which is not allowed. For example, the garage can only put cars, and the storage room can only put things that are not used at ordinary times. The contract for this house stipulates the type of house. However, it is definitely not possible to go through formal procedures. You can consult with the person in charge of the residential property to improve the relationship. If you have checked, close the door first. As long as it doesn't affect other owners, it should be nothing. I hope to give you a reference.
