Mountain House is a census-designated place and planned community in San Joaquin County, California. An exurb of the San Francisco Bay Area, Mountain House is 5 miles (8 km) from the City of Tracy near Interstate 205. The community of Mountain House in San Joaquin County lies two miles (3 km) northeast of and borrows the name of Alameda County’s historical Mountain House, a halfway stop for forty-niners passing over the Altamont Pass (historic Livermore Pass) on their way to the gold country of the Sierra Nevada foothills located at the base of the Diablo Range on the western edge of California’s Central Valley.
In November 2008, the community appeared in nationwide news reports as having the highest percentage of negative equity in the United States – the most homes “under water” (worth less than their mortgage). In 2012, despite a partially outdated land plan and a lack of retail and industrial centers, Mountain House was experiencing economic recovery. In 2010 CDP’s population was 9,675. In 2015, the population was around 14,000. The Cholbon triblet of the Northern Valley Yokuts were the original inhabitants of the Mountain House area. Their territory ran along Old River a distributary of the San Joaquin River.
As of 2018, Mountain House includes the established villages of Altamont, Bethany, Wicklund, Questa, Hansen and the developing sixth village of Cordes. At the end of 2012 approximately 3,500 homes were in Mountain House. Some 15,500 households or approximately 40,000 people are anticipated when Mountain House is fully completed. Construction began in 2001, but expansion stopped because of the Great Recession. Development accelerated through 2011 and 2012. Questa had six neighborhoods in various stages of completion, and three additional neighborhoods scheduled for 2013 openings. Also completed is Questa’s K-8 school and a village park. Mountain House High School opened for the 2014-2015 academic year. All schools are part of Lammersville Unified School District.
Mountain House was projected to be a small full-fledged city developed over 30-year period by Trimark Communities. The community covers 4,784 acres (1,936.0 ha) in San Joaquin County. The town was planned for 12 distinct neighborhoods including 10 family neighborhoods and two age-restricted neighborhoods each organized around a center containing a neighborhood park, a K-8 school, and a small commercial area.
