Landlords are not responsible for the loss of personal property of a tenant after a fire. This is because the landlord had no control over the fire or over what property the tenants decided to keep in the rental unit.
In addition to this responsibility to the tenants, landlords may also be partially responsible for protecting the surrounding community from criminal acts of the tenants. For example, some states have codes and statutes that impose liability on landlords for renting property to drug dealers.
