If this is a room in a private residence owned by the landlord, the landlord lives in the premises, and there is only the one tenant, then the landlord can give thirty days notice under California's single lodger law, and can attempt to remove the tenant as a trespasser at the end of the notice period. If the single lodger law does not apply, the tenant must ordinarily be given sixty days notice (see Civil Code, Sec. 1946.1 for notice rules and exceptions) but the tenant must be evicted through a legal action if she remains in occupation at the end of the notice period.
