Mountain House, CA population, income and ZIP codes

Mountain House CDP is a small city in California, with 25,108 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #303 of 1,618 ranked by population — larger than 81% of them. The median age here is 34.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Mountain House CDP earn a median of $171,675 a year, 118.6% above the national figure of $78,538 and 88% above the $91,111 median for the 1,050 California cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 2.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Mountain House CDP is valued at $859,700, 183.4% above the national figure and 46% above the $589,600 peer median, while median gross rent runs $3,232 a month, 129.9% above the national figure, or roughly $38,784 across a full year. A household on the local median income would put about 22.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 73.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
