CA Civ Proc Code Section 700.080

(a)

To levy upon personal property used as a dwelling, the levying officer shall serve a copy of the writ of execution and a notice of levy on one occupant of the property. Service on the occupant shall be made by leaving the copy of the writ and the notice of levy with the occupant personally or, in the occupant’s absence, with a person of suitable age and discretion found at the property when service is attempted who is a member of the occupant’s family or household. If unable to serve the occupant at the time service is attempted, the levying officer shall make the levy by posting the copy of the writ and the notice of levy in a conspicuous place on the property.

(b)

If the judgment creditor so instructs, the levying officer shall place a keeper in charge of the property for a period requested by the judgment creditor.

(c)

The judgment creditor may apply to the court on noticed motion for an order directing the levying officer to remove the occupants. The notice of motion shall be served on any legal owner and any junior lienholder who was served pursuant to Section 700.090, on the occupant, and, if the judgment debtor is not the occupant, on the judgment debtor. Service shall be made personally or by mail. At the hearing on the motion the court shall determine the occupant’s right to possession and shall make an order including terms and conditions that are appropriate under the circumstances of the case.

(d)

Personal property used as a dwelling shall include a mobilehome, whether the mobilehome is occupied or unoccupied at the time of the levy.
