Finding Eviction Notices

I went to our county courthouse to ask for eviction filings.
( I want to market to troubled landlords). I was told:

  1. They don’t keep a list.
  2. The filings are confidential for 90 days.
    I live in Northern California
    There maybe a legal newspaper that attorneys get, but I can’t find one.
    I checked with a few listing services, no legal info.
    Does anyone have any suggestions?
    Thanks to everyone

have someone spend some time at the court the day the judge hears the cases.
