That's not an eviction in CA. Evictions in CA are through the courts and there is a Judge making a legal judgement on the case.
Serving a 90 Day notice to terminate a month to month tenancy is simply saying "I as a landlord (adult) is not continuing a month to month contract with you Tenant (another adult)".
There is a huge push by the insane liberal left to change words and their definitions...
The media, politicians and the leftest activists in California have been pushing the "eviction" narrative for the last few years and they are really ramping up the incorrect use of the word to be a catch all phrase for any lawful ending to a term contract. It is extremely dishonest and as a LL frustrating. Sadly, the left is winning this fight over the correct definitions; landlords who know the laws are now using the term eviction incorrectly due to the fact that the narrative is being pushed so heavily by advocate groups.
Sadly, the left in CA wants all housing to be subsidized for everyone and to control all zoning laws stripping away local zoning authority to give free handouts to all. The state is going to be left with ulta high end market rate housing and gov. subsidized housing with nothing in the middle. What could go wrong?
