Mountain House, California

**Mountain House** is a planned city in San Joaquin County, California. The county government approved the plan in 1994, and the first houses sold in 2003. Mountain House legally became a city in 2024. The number of people was about 30,000 in 2023.

Mountain House was built on dry farmland in the foothills. It is made of smaller "villages". Each village has thousands of houses, and an elementary school in the middle. The plan for the city said it would have 44,000 people and 21,000 jobs. But there were fewer than 1,500 jobs as of 2023. The city has mostly houses and not many stores, restaurants, or other businesses. Half of the people living in Mountain House are Asian-American.

## History

In the 2000s, many people bought houses in Mountain House because it was much cheaper than the San Francisco Bay Area. The California government pension fund invested over $1 billion in the Mountain House development. When the Great Recession started in 2008, the houses decreased in value. Nine out of ten houses were worth less than their mortgage. When the economy got better, many more houses started selling. As of 2023, the number of people is growing quickly.

In 2024, people in Mountain House voted to incorporate it as a city.
