This paper defines the criteria for the building owner's responsibility and the tenant's one against the damage that a visitor received from the defects of a building. The building owner's responsibility and the tenant's one are defined Civil law Art. 717. But the Art. 717 can't settle some cases. Then, this paper reached the criteria by analyzing the decisions of courts and theories. The owner and tenant who have administered and controlled the defects are responsible for the damage that a visitor received from the defects.
