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 5 miles (8 km) from the City of Tracy near Interstate 205. It is two miles (3km) northeast of Alameda County's Mountain House. 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 In 2012, in spite of a partially outdated land plan and a lack of retail and industrial centers, Mountain House was experiencing economic recovery.
