US New Home Construction Slows Despite 4.7 Million Unit Deficit

New home construction in the United States is slowing despite a national housing deficit of 4.7 million units. A report from Zillow indicates that residential building permits fell 1.7% from last year and remain 19.4% below pre-pandemic trend lines. Detached single-family home completions declined for the third consecutive year in 2025, reaching their lowest level since 2020.

The pullback is most severe in Sun Belt markets, where Austin and San Antonio saw annual drops of 25.3% and 24.1%, respectively. To maintain affordability, builders are reducing home and lot sizes. While the United States Census Bureau reported a slight 0.9% decrease in the median new home price to $393,800 as of July, the National Association of Realtors noted that existing-home prices continued to rise, reaching a median of $429,100.

Economists warn that this trend could create future volatility. Kara Ng of Zillow noted that builders are responding to a softer market by pulling back, though the underlying housing shortage remains intact. Jeff Ostrowski of Bankrate added that the long-term need for housing for a population of 340 million persists, but builders in previously active areas now have the most incentive to stop building and let the market absorb existing inventory. Experts caution that a thinner construction pipeline may drive prices higher once buyer demand returns.
