The workplace half of this city's birthday volume is unusual, because Baldwin Park's best-known employer is a hamburger company that was born here. In-N-Out Burger opened its first stand in Baldwin Park in 1948, and the company's campus and In-N-Out University still sit off Francisquito Avenue, with a replica of that original stand built alongside — even with the head office moving to Irvine, the Baldwin Park operation is the address most people in town can give you from memory. The other large in-city employer is Kaiser Permanente Baldwin Park Medical Center on Baldwin Park Boulevard, where the recipient is as likely to be a nurse finishing a twelve-hour shift as a patient. Beyond that the working addresses are industrial: the Puente Avenue and Arrow Highway belt, the Irwindale yards north of the 210 including the Huy Fong Foods sriracha plant on Azusa Canyon Road, and the vast City of Industry warehouse district to the south. Add City Hall on East Pacific Avenue, the Baldwin Park Unified school offices, the retail payroll at Plaza West Covina, and the commuters who catch Metrolink from the platform downtown and work somewhere else entirely — including Southern California Edison's headquarters on Walnut Grove Avenue in Rosemead. Industrial addresses almost never accept a delivery at the front office; name the receiving door and give a mobile number, because a driver at a roll-up gate with nobody answering is a failed delivery, not a delayed one.
The residential half has one local habit that decides whether the flowers land. Across 91706 an enormous number of lots hold two homes on one parcel — the main house at the street and a back house, converted garage or newer accessory unit behind it, often with the grandmother or a married adult child living in it. If your recipient is in the rear dwelling, write "rear unit" or the letter the family uses on the address line, because a driver who knocks at the front door meets a relative who may not know about the surprise, or nobody at all. The same care applies to the driveway gates that front so many houses on Olive, Merced, Vineland and the streets off Francisquito: a gate code or a phone number beats a note that says *leave at door*. On the apartment side, the complexes along Ramona Boulevard and Maine Avenue run callboxes, and a callbox with an unlisted or misspelled surname fails silently — give us the unit number and the dial code. One more thing specific to 91706: the ZIP is bigger than the city, spilling into Irwindale, a slice of West Covina and unincorporated county pockets, so an address that says 91706 is not proof of a Baldwin Park city address. Give us the cross street and the routing takes care of itself.
