How to deal with the major security risks caused by private cooperation between property and third parties?

Responsibility. The realty service enterprise shall be liable for breach of contract if it fails to eliminate some potential safety hazards in residential quarters in time. Property service enterprises have the obligation to maintain some potential safety hazards in residential quarters, and eliminate some potential safety hazards that damage the property of owners in residential quarters in time. Otherwise, the realty service enterprise shall bear the liability for breach of contract and compensate the owners for their losses. Even if the potential safety hazard is caused by a third party, it cannot exempt the realty service enterprise from the liability for breach of contract. If the property loss of the owner is caused by the infringement of the residential area by a third person, and the property service enterprise has fulfilled its maintenance obligation, it can be exempted from the responsibility of the property service enterprise, and the infringement by the third person is unpredictable and inevitable.
