Alpine Mobile Home Estates is a 55-and-over manufactured-home community in Alpine with 165 paved-street sites, a residents' clubhouse, swimming pool, and covered recreation hall at 2400 Alpine Blvd. The age-qualified demographic connects to the senior-care network forming along Arnold Way in Alpine, where Alpine View Lodge provides residential assisted living for residents who eventually transition to higher-acuity settings. Built in 1969, the park now contains roughly 80 percent double-wide units with peaked rooflines and lap siding, and small pets weighing 25 pounds or under are permitted on each lot. Alpine's 91901 zip falls within San Diego County's Climate Zone 2 hot-dry designation, meaning manufactured-home HVAC loads run higher than coastal setups — Afterhours Heating & Air Conditioning in Alpine services the packaged split systems common to the park's double-wide inventory. Each of the 165 lots connects to city-sourced water and municipal sewer, and the community's 2,000-foot elevation positions it above San Diego's coastal fog line while keeping it below the snow-risk threshold of the Laguna Mountains.
