CoStar: U.S. Retail Construction Activity Remains Stymied Through the First Quarter

U.S. retail construction activity totaled 64.2 million square feet in the first quarter of 2026, marking a decrease from the previous year and falling below the 10-year average. Various factors such as e-commerce popularity, competition from other property types, and elevated costs for land, materials, labor, and debt are hindering new retail developments. Despite a challenging environment, Texas markets like Dallas, Houston, and Austin are leading in new construction with significant preleased space in their pipelines.
