U.S. Geological Survey Geographic Names Information System: Mountain House, San Joaquin County, California

Mountain House is a census-designated place and planned community in San Joaquin County, California. An exburb of the San Francisco Bay Area, Mountain House is located 5 miles (8 km) from the City of Tracy near Interstate 205. In November 2008, the community appeared in nationwide news reports as having the highest percentage of negative equity in the U.S.—the most homes "under water", worth less than their mortgage. In 2012, in spite of a partially outdated land plan and a lack of retail and industrial centers, Mountain House is experiencing economic recovery.[5] In 2014 the town population was around 12,000.[4]

Development plan[edit]

Mountain House was projected to be a small full-fledged city developed over 30 year period by Trimark Communities.[6] The community covers 4,784 acres (19.4 km2) 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. Today’s Mountain House includes the established villages of Altamont, Bethany, Wicklund, Questa and the developing fifth village of Hansen. At the end of 2012 approximately 3,500 homes were in Mountain House.[7] Some 15,500 households or approximately 40,000 people are anticipated when Mountain House is fully completed.[8] Construction at Mountain House began in 2001, but expansion stopped because of the Great Recession. Development accelerated through 2011 and 2012. Questa has 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.[9] All schools are part of Lammersville Unified School District.

Financial downturn[edit]

In November 2008, The New York Times reported that Mountain House was the "most underwater community in America,"—the zip code with the highest amount of negative equity on its homes.[16] With home values decreasing across the nation, Mountain House was described as the worst-hit, with 90% of its homes worth less than the amount their owners owe in mortgages.[16] The average homeowner in Mountain House was reported to be $122,000 in debt.[16] Many local businesses in the 95391 zip code were closing because the homeowners were cutting back on their spending and could not support them.[16]

CalPERS, an agency that manages pensions for California public employees, invested heavily in Mountain House beginning in 2005, purchasing approximately 9,000 residential lots from Shea Homes. By May 2010, the $1.12B investment by CalPERS had been reduced to 18% of that figure: $200M.[17] Even though home values had dropped significantly, CalPERS determined that they would hold onto the investment, counting on a recovery of the housing market.[17]

Economic recovery[edit]

An up tick in economic performance at Mountain House was noted in September 2011 by Big Builder, a trade magazine of major land and housing development published by Hanley-Wood.[18]

Acknowledging the New York Times 2008 article that branded Mountain House as the most underwater community in America, the article also chronicled a grass roots commitment by Mountain House residents to keep their neighborhoods looking well kept by mowing neglected lawns of homes in foreclosure, short sales or simply abandoned.

This community spirit helped persuade CalPERS to hold onto its Mountain House investment, despite the drawbacks of a 1994-vintage land plan, termed “out of synch with the realities of the post-housing crash world.” Helping to balance the challenges of the land plan was the level of established infrastructure and homebuyers motivated by affordable pricing, proximity to job centers and traditional neighborhoods.

In April of the following year, Big Builder again reported on the community, noting more robust first-quarter sales, new lot offers, and flexibility for semi-finished and raw land in terms of future development.[5]
