Legal Question in Landlord & Tenant Law in California

http://www.dca.ca.gov/publications/landlordbook/catenant.pdf

The question is very broad; in general, for a month to month tenancy you must give a written notice that you do not plan to renew the rental thirty days from the date of the notice. If the tenant has lived there for more than one year, only the landlord must increase that notice by an additional thirty days.
