A Seasonal Mountain Community

Cedar Glen sits in the San Bernardino Mountains at 4,800 feet elevation, about 15 miles northeast of San Bernardino. This mountain community has 1,310 year-round residents but swells during weekends and summer months. With 587 of 1,249 homes (47%) used seasonally, vacation properties outnumber primary residences.

Why PO Boxes Are Required

The Cedar Glen post office is a PO Box Only Zone. No street delivery exists across the 7 square mile territory. The post office maintains 597 PO Boxes for 550 occupied homes, an adoption rate of 1.09x. Every resident needs a PO Box. Seasonal homeowners keep boxes year-round to receive mail when they aren't in residence.

The Mountain Setting

Housing patterns show the seasonal character clearly. Of 1,249 total homes, 550 are occupied year-round and 699 are vacant. Most of those vacant units (587) are for seasonal use. Street names like Lakeview Drive, Alder Lane, and Tamarack Road point to the mountain setting. Hook Creek Road follows a local stream.

Demographics of a Mountain Retreat

Median home values reach $480,000. The population skews older, with a median age of 46.2 years. Only 34 residents are under 18. This isn't a family vacation spot but a getaway for adults and retirees. Owner-occupied homes (391) far outnumber rentals (159), suggesting second homes rather than vacation rental properties.

Local Economy

The community has limited commercial activity. Just 23 business establishments employ 136 workers. About 30% of workers commute from home, higher than most areas. Transportation and warehousing employ 120 people, likely serving the mountain delivery routes and seasonal traffic. Federal government workers number 42, possibly linked to nearby San Bernardino National Forest.
