California - Close to Evicting a Tenant. Steps?

[Jonathan Ko]

BP,

Asking for another individual.

A tenant has leased the unit for the last two years. Their contract is about to expire at the end of the month (March), and the landlord does not want to renew the lease contract. Given that it's California, what are the laws/rules as it relates to having them relocate within the allotted timeframe, however long that may be?

A realtor noted that in California, the inhabitants have one month of "buffer" for each year they've lived on the premises. So, does this mean that the landlord just needs to provide a letter to the individual that states that:

1) They will not be renewing/extending the lease,
2) By law, they have 60 days' grace period to find another living situation (same lease amount per expired contract)
3) If they have not vacated the premises after the 60-day period, then legal action may be taken?

Links/leads to any resources that will assist me in answering the questions above would be greatly appreciated. Thanks!
