History
In 1849, Thomas Goodall erected a blue denim cloth tent to serve as a midway stopover for gold miners headed from San Francisco to the Sierra Nevada foothills via Altamont Pass. Goodall eventually built an adobe house at the eastern edge of the Diablo Range hills, calling it The Mountain House. Simon Zimmerman later acquired the stop and it became known as Zimmerman's Mountain House and became a well-known way station stop on the way to Stockton. The last remaining settlement buildings were leveled in 1940.
In November 1994, the San Joaquin County Board of Supervisors officially approved the new community of Mountain House. In 1996, the master plan was approved. In August 2000, many of the documents controlling the development and growth of Mountain House were adopted and approved by the San Joaquin Board of Supervisors acting as the Mountain House Board of Directors.
Mountain House was projected to be a small full-fledged city developed over a 30-year period by the Master Developer Trimark Communities. The community covers 4,784 acres (1,936 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.
Construction began in 2001, but growth slowed down to about 50 permits per year because of the Great Recession in 2008. Development started again with increasing building permits and small land development projects in 2010 and 2011 and has continued at a high rate.
As of 2013, Mountain House included the established villages of Wicklund, Bethany, Altamont, Questa, Hansen, Cordes, and College Park. Some 15,000 households or approximately 45,000–50,000 people are anticipated when Mountain House is fully completed.
Local control led Mountain House residents to seek incorporation as California's newest city in 2024. In the March primary election, more than 90% of voting residents voted for incorporation. The city officially came into existence on July 1, 2024, and celebrated with a ceremony on July 4.

Financial downturn
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. 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. The average homeowner in Mountain House was reported to be $122,000 in debt. Many local businesses in the 95391 ZIP code were closing because the homeowners were cutting back on their spending.
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 $1.12 billion investment by CalPERS had been reduced to 18% of that figure: $200 million. Even though home values had dropped significantly, CalPERS determined that they would hold on to the investment, counting on a recovery of the housing market.
Economic recovery
An uptick 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.
Acknowledging the New York Times 2008 article that branded Mountain House as the most underwater community in America, the article chronicled a grassroots commitment by residents to keep their neighborhoods looking well-kept by mowing neglected lawns of homes in foreclosure, short sales or 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 sync 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 2012, 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 future development.
Geography
Mountain House lies on the foothills of the Diablo Range, and close to the Altamont Pass which is over 1,000 feet (300 m) in elevation. It is on the border of Alameda and Contra Costa counties. According to the United States Census Bureau, the CDP covers an area of 3.2 square miles (8.3 km2), all of it land. The census definition of the area may not precisely correspond to local understanding of the area with the same name. The community is bisected by Mountain House Creek. Mountain House Creek originates south of the Altamont Pass and Interstate 580, flowing northeasterly along and crossing under the interstate, then along Grant Line Road to the intersection with Mountain House Road at the historic Alameda County Mountain House. The creek continues northeasterly through the residential communities of Mountain House before emptying into the Old River, a distributary of the San Joaquin River.
