In southern Riverside county a few years ago, it was about 40 days in a semi optimal scenario – tenant answered court paper to Unlawful Detainee law suit, but didn’t show up in court hearing. It could be 25 days in most optimal case if tenant doesn’t answer court papers. For sophisticated tenant and they go to the court hearing and they can find excuses like medical issues, judge can give them a few extra months to stay. They may do multiple hearing and each hearing grants a few months of extra stay.
I don’t remember number exactly. I think roughly at those numbers:
3 days notice
2-3 days file unlawful detainee and delivered tenant copy
7-10 days wait tenant answer for court papers.
If tenant answer received, schedule court hearing which will happen 15 days later
if no tenant showing in court hearing, judge awards the landlord victory immediately. The process can get very long if sophisticated tenant shows up and he will use all kinds of excuses he learned from tenant lawyer.
