A landlord who wishes to terminate a periodic (month-to-month) tenancy may do so by properly serving advanced written 30-day or 60-day notices on tenants. The operative word is properly. The reality is that most “mom and pop” landlords are on cruise control and don’t know the “ins and outs” of landlord-tenant law, namely California Civil Code section 1946 et. Seq. Over the years I defended many tenants who were improperly served by the landlord – the result of which was a delayed end of the tenancy. By failing to properly serve notice the landlord will be surprised when they find out (usually at the end of the 30 or 60 day period) that they need to re-serve the notice thus resetting the calendar for another 30 or 60 day period.
