Get ready for a gigantic cartload of new shopping opportunities in Houston. A new report indicates the equivalent of 21 Walmart supercenters is under construction in the region.

The report, published by commercial real estate services provider Lee & Associates, says Houston has nearly 3.9 million square feet of retail space under construction, making it the second most active market for new retail space in the U.S.

To put that in perspective, given the average Walmart supercenter measures 182,000 square feet, the 3.9 million-square-foot total would work out to 21 new supercenters being built in the region.

Dallas-Fort Worth is by far the most active U.S. market for new retail space; DFW leads more than 60 U.S. retail markets with nearly 7.15 million square feet of space under construction. The amount of retail space going up in DFW represents 15 percent of all retail space under construction in the more than 60 U.S. markets tracked by Lee & Associates.

Houston and Austin aren’t too far behind Dallas-Fort Worth, though.

Third-ranked Austin area has more than 3.4 million square feet of retail space being built.

What’s behind the surge in retail construction across Texas? Population growth.

Data recently released by the U.S. Census Bureau shows Houston was the second-fastest-growing metro from 2023 to 2024. DFW was the country’s third-fastest-growing metro from 2023 to 2024, based on the number of new residents, and Austin landed at No. 13.
