Chinese Camp isn't a traditional vacation island, but it functions as one. This Sierra Nevada foothill community of 9 residents operates almost entirely as second-home territory, with 4 of its 5 total housing units sitting vacant for much of the year. That's an 80% seasonal vacancy rate.
The post office maintains 136 PO Boxes for just 1 occupied household, creating an adoption rate of 136.0. This doesn't mean locals are desperate for mail service. It means property owners scattered across 6.5 square miles need year-round mailing addresses for vacation homes, mountain retreats, and investment properties they visit seasonally.
Street delivery exists but reaches only a handful of addresses along Red Hill, Shawmut Road, Lily Lane, and Rojo Lane. Most properties rely on PO Boxes by choice, not necessity. When you own a second home in a remote foothill location, a post office box provides secure mail handling whether you're there or not. Chinese Camp's tiny residential footprint (just 0.018 square miles of developed land within a much larger ZIP boundary) makes centralized mail collection practical.
The four street names reflect the area's natural topography and minimal development. Red Hill references the characteristic Sierra foothill terrain, while Spanish-influenced names like Rojo Lane hint at California's Gold Rush and ranching heritage. With just 6 total street delivery records across all four roads, this is one of the least-developed ZIP codes in California.
