Answer:
Sixteen or more.
Explanation:
It is mandatory by law in California to have an onsite manager, housekeeper, janitor, or another responsible person reside in a building with more than 16 apartments. Onsite means the manager or caretaker must be a resident in the building complex. The manager's role is to attend to the tenant's needs and offer protection to their properties. This requirement applies if the landlord is not a resident in the apartment building.
