Fastest-growing ZIP codes in America revealed – and the top spot is in SoCal

A Southern California ZIP code is booming more than any other in the US — with its housing stock exploding by more than 1,300% in nearly a decade, according to a new analysis of the fastest-growing areas in the nation.

Housing in Chino’s 91708 ZIP code grew 1,318% between 2014 and 2023, while its population skyrocketed 402%, a RentCafe report found.

Chino, located in San Bernardino County, is an Inland Empire enclave known for agriculture and dairy farming.

Data suggests the boom has been driven by young families looking for affordable housing. The median age of residents there is 33, according to US Census data, with household incomes of $109,000. Seventy-three percent of households are married, with an average household size of 3.3 people.

The boom has been driven by The Preserve at Chino housing development, the Orange County Register reported. The development sits on 5,435 acres of former farm and dairy property, with roughly half made up of residential, commercial, industrial and airport-related development. 

Two other Southern California ZIP codes — Irvine’s 92618 and Los Angeles’s 90094 — also made the list of America’s fastest-growing.

The Irvine ZIP code was the 20th fastest-growing in the country, according to the analysis, with the area’s housing stock jumping 172% over nine years. The area is more affluent than Chino, with an average household income of $146,000 and an average home value of $1.24 million.

The Orange County community is known for being a tech hub with top-class educational institutions.

The Los Angeles ZIP code’s rapid growth is largely due to development in Playa Vista, which occurred at the the former headquarters of Hughes Aircraft Company. The area has rapidly grown since construction began in 2002.

The area saw 115% housing growth over the last nine years, with the population roughly doubling.

Residents in the area are a bit older than the other two zip codes, with a median age of 38 and a $146,000 household income.

A fourth ZIP code on the list, Friant’s 93626 in Fresno County, saw 144% housing growth, with 274% population growth.

California came in third among all states with ZIP codes among the top-50 fastest-growing in the nation. Texas came in first with 17, and Colorado in second with seven.
