Civ. Code, § 799.65

The management may terminate the tenancy of a defaulting tenant for nonpayment of rent, utilities, or reasonable incidental service charges, provided the amount due shall have been unpaid for a period of five days from its due date, and provided the tenant has been given a three-day written notice subsequent to that five-day period to pay the total amount due or to vacate the park. For purposes of this section, the five-day period does not include the date the payment is due. The three-day notice shall be given to the tenant in the manner prescribed by Section 1162 of the Code of Civil Procedure. Any payment of the total charges due, prior to the expiration of the three-day period, shall cure any default of the tenant. In the event the tenant does not pay prior to the expiration of the three-day notice period, the tenant shall remain liable for all payments due up until the time the tenancy is vacated.
