Nothing in this chapter or in any existing ordinance of the city shall operate to restrict the right of a tenant and park owner to enter into an agreement in accordance with California Civil Code Section 798.17. Pursuant to Civil Code Section 798.17 (c), the tenant shall have the option to reject the offered rental agreement and accept a rental agreement instead for a term of twelve (12) months or less, including a month to month agreement. No park owner may require, directly or indirectly, that any tenant or prospective tenant sign a lease or rental agreement with a term in excess of twelve (12) months or that provides that it shall be exempt from local rent control as a condition of tenancy in the park, and no park owner may deny a tenancy to a prospective purchaser of a mobilehome in the park on the ground that the prospective purchaser of a mobilehome in the park on the ground that the prospective purchaser will not sign such a lease or rental agreement.
