Property Manager Misconduct

[Hui Wang]

I have hired a licensed property manager for several months to help me manage condominium unit in San Diego, California. However, I must say that the performance of this account has been far from satisfactory, and has eventually ended with a nasty eviction. Not until now, it turned out that the tenant has a history of drug use, and has been arrested for several charges. I believe the issue raised from the property manager's failure in the initial tenant screening. 

My question is, are property managers obligated to properly screen perspective tenants for credit history and criminal background? If they are, can the failure to screen tenant be used against property managers in law suite for the lost as the result of eviction?

I appreciate all the help in advance.
