California Code, Civil Code - CIV § 2081.1

If within 60 days after its receipt no person calls for the property and pays the freight and charges upon it, the carrier, commission merchant, innkeeper, or warehouseman may sell the property, or so much of it as will pay freight and charges, to the highest bidder at public auction, after first causing such notice of sale to be given as is customary in sales of goods by auction at the place where the goods are held or stored.
