How to deal with the property where the security door exploded shortly after the new house moved in?

The security door is broken, and the property is not repaired, but the property is only in public areas. If the owner's own entrance door is broken, then the residential property can also help to call someone to repair it, but the owner needs to bear the maintenance costs himself.
