The California 30 Day Notice to Landlord of Termination is a written notice that serves as a formal notification to a landlord that a tenant wishes to end their tenancy and vacate the rental premises. This notice is required under California law in order to properly terminate a tenancy that is month-to-month or periodic. The notice must be given 30 days before the tenant vacates the property. Depending on the type of tenancy, there are two types of California 30 Day Notice to Landlord of Termination: 30-Day Notice to Terminate Tenancy and 60-Day Notice to Terminate Tenancy. The 30-Day Notice to Terminate Tenancy is used when the tenant has a month-to-month or periodic tenancy and wishes to vacate the premises within 30 days. The 60-Day Notice to Terminate Tenancy is used when the tenant has a fixed-term lease and wishes to vacate the premises within 60 days. Both notices must include the date of notice, tenant's name and address, landlord's name and address, the rental date, and the date of vacating the rental premises. The tenant must also provide a forwarding address for return of the security deposit. The California 30 Day Notice to Landlord of Termination is an important document in the process of ending a tenancy in the state of California.
