As Texas' ever-growing population generates more demand among regional housing markets, one San Antonio ZIP code has seen more growth than many other ZIPs in the United States.

San Antonio's southwestern 78252 ZIP code ranks No. 15 in RentCafe's new study that analyzed the 50 fastest-growing "new neighborhoods" in the U.S. "that barely existed a decade ago." Two more local ZIPs, located in west San Antonio and Boerne, also made the cut.

The study reviewed housing inventory and population growth across 32,000 U.S. ZIP codes and narrowed down the search to the top 50 locales that experienced a 51 percent minimum surge in new housing units from 2014-2023.

Overall, Texas dominated the list with 17 of the nation's 50 booming new neighborhoods.

RentCafe determined the 78252 ZIP code in San Antonio saw a 187 percent surge in housing inventory in the last decade to keep up with the area's 111.6 percent population growth over the same period.

In 2014, there were just 8,629 residents living within the bounds of 78252, which stretches as far west as Gross Lane near Lacoste and as far east as the Solana Ridge and Pearsall neighborhoods. During that same year, there were only 2,073 housing units in the area, which has since spiked to 5,943 units as of 2023. The ZIP code now boasts a population of more than 18,000 residents, the study found.

Elsewhere in the San Antonio area, 78015 in Boerne and Fair Oaks Ranch, and 78253 in west San Antonio, respectfully ranked as the 44th and 49th fastest-growing ZIPs in the U.S. over the last decade.

The report's findings revealed the Fair Oaks Ranch area has more than doubled its housing inventory to 8,412 units, up from about 3,800 units in 2014. The area's population has also more than doubled, from 10,771 to 23,548 residents as of 2023.

The far west San Antonio population in 78253 has surged 105.5 percent over the last decade, from 32,884 to 67,578 residents, and housing inventory soared 115 percent to keep pace with the growth.

The top 10 "newest" neighborhoods in the U.S., says RentCafe, are:

• No. 1 – Chino, California (91708)
• No. 2 – Timnath, Colorado (80547)
• No. 3 – Colorado Springs (80927)
