Civ. Code, § 798.34

(a) A homeowner shall not be charged a fee for a guest who does not stay with the homeowner for more than a total of 20 consecutive days or a total of 30 days in a calendar year. A person who is a guest, as described in this subdivision, shall not be required to register with the management.

(b) A homeowner who is living alone in the mobilehome and who wishes to share occupancy of their mobilehome with one other person, to be designated as the homeowner’s companion, may do so, and management shall not impose a fee for that person. For purposes of this subdivision, a homeowner may only designate one person at a time as a companion and shall not designate more than three companions in total during any calendar year, unless otherwise authorized by management. Management may refuse to allow a homeowner to share their mobilehome with a companion under this subdivision if park residency is subject to age restrictions and the proposed companion is unable or unwilling to provide documentation that the proposed companion meets those age restrictions.

(c) A homeowner may share their mobilehome with any person over 18 years of age if that person is providing live-in health care, live-in supportive care, or supervision to the homeowner. Management shall not charge a fee for the live-in caregiver but may require written confirmation from a licensed health care professional of the homeowner’s need for the care or supervision, if the need is not readily apparent or already known to management.

(d) A senior homeowner who resides in a mobilehome park that has implemented rules or regulations limiting residency based on age requirements for housing for older persons, pursuant to Section 798.76, may share their mobilehome with any person over 18 years of age if this person is a parent, sibling, child, or grandchild of the senior homeowner and requires live-in health care, live-in supportive care, or supervision. Management shall not charge a fee for this parent, sibling, child, or grandchild, but may require written confirmation from a licensed health care professional of the need for the care or supervision, if the need is not readily apparent or already known to management. As used in this section, “senior homeowner” means a homeowner who is 55 years of age or older.

(e) A guest, companion, live-in caregiver, or family member under the care of a senior homeowner, as they are described in this section, shall have no rights of tenancy in the park, and any agreement between the homeowner and the guest, companion, live-in caregiver, or family member under the care of a senior homeowner shall not change the terms and conditions of the rental agreement between management and the homeowner.

(f) A violation of the mobilehome park rules and regulations by a guest, companion, live-in caregiver, or family member under the care of a senior homeowner, as they are described in this section, shall be deemed a violation of the rules and regulations by the homeowner and subject to subdivision (d) of Section 798.56.

(g) Nothing in this section shall be interpreted to create a duty on the part of management to manage, supervise, or provide care for a homeowner’s guest, companion, live-in caregiver, or family member under the care of a senior homeowner, during that person’s stay in the mobilehome park.
