Eviction of couple renting room in owner occupied home in ca.

I'm in CA and rent my two rooms to a couple & another female. i have been trying to get the couple out of my house for the past 8 months. i have hand delivered on 7/1 a 60 day notice, then on 9/1 a 30 day notice to the couple w/no success of them leaving. they have lived here with me going on 2 yrs. the one yr lease has already expired and is in month to month. they have harassed me and my family and other roomies to the pt of others leaving. this month they used 1/2 their security deposit to pay for rent,and refused to pay actual rent as the lease states u cant use deposit as rent. the male member smokes weed in and outside the premises even though on the rental app they stated no smoking or drug use. they are saying i cant evict them because i didn't give them proper notice and they should have another 60 day notice instead of the 2nd 30 day notice i gave them again. Is this true since on month to month it only requires 30 day notice? can my claim hold up and win if i file a unlawful detainer with the court?
