If a valid reason for evicting a tenant exists, the landlord should then give the tenant a 3 day notice or pay rent or quit their infractions. This notice can either be physically handed to the tenant, physically handed to an adult at the property and mailed to the tenant, or posted on the tenant’s door and mailed to the tenant.
After the tenant has not remedied the situation in the allowed time period, a property owner can begin the process of Unlawful Detainer Action. This requires filing a formal complaint through the court system, serving the tenant another notice, waiting the appropriate period, and completing the court process.
These are just the general guidelines of tenant eviction in California; it’s important you consult with a qualified tenant eviction legal professional before instigating any part of the tenant eviction process
