Welcome to landlording in liberal California, where lefty politicians have succeeded in raising rents and deposits via efforts to “protect” tenants. The result is hurting the poor, people with children, anyone with a dodgy work history or past eviction.
Long ago I had San Diego apartments and would occasionally take a chance with such an applicant. Sometimes it worked out, often it did not. When it worked out, I felt good about helping them get their life together.
Now, thanks to the nightmare landlords put up with, as described by the commentators above, landlords must act defensively, to the detriment of poor people. Thanks, CA politicians.
