US home permitting sinks to 19.4% below its pre-pandemic trend after 44 straight months of declines

The 44-month streak ^[3] is long, but the latest year's decline is small. A 1.7% annual drop on just over 1.42 million permits ^[1] is roughly 24,500 fewer permits than the prior twelve months ^[1]. The gap to trend is far larger. If 1.42 million sits 19.4% below the 2016-2020 trajectory ^[2], that trajectory is near 1.76 million, a shortfall of about 340,000 permits a year ^[2]. Last year's drop explains only about 24,500 of that gap ^[1].

Faster building does not change that count. The median detached home took six months to finish in 2025, a month quicker than in 2022 and 2023, as the pandemic-era backlog cleared ^[4]. If starts hold steady, the number of homes under construction at any moment scales with build time. A six-month build therefore carries about 14% fewer homes in progress than a seven-month one ^[3]. Detached completions still fell 2.5% in 2025, to about 817,000 from roughly 838,000, though that is above the roughly 782,600 finished in 2019 ^[5][4].

The pullback is steepest in the Sun Belt. Austin permits fell 25.3% and San Antonio's 24.1%, in markets where inventory has surged ^[6]. The gains come from low bases on the coasts and in the Midwest, where San Jose more than doubled at 122% ^[14]. Los Angeles rose 30.6% to 34,696 permits ^[7], an increase of about 8,100, or roughly a third of the national decline ^[5].

"Builders are responding to a softer market by pulling back, especially in the places they'd been building the most," said Kara Ng, senior economist at Zillow ^[10]. "The concern is that when conditions improve and buyers return, the thinner pipeline could mean a tighter market that drives up prices," she said ^[15].

The homes are smaller too. The median new detached home measured 2,300 square feet in 2025, against 2,400 in 2019, on a median lot of 8,700 square feet against 9,000 ^[8]. Zillow says lots shrank by more. That holds in square feet (300 against 100), but in percentage terms the house fell about 4.2% and the lot about 3.3% ^[7]. The smaller lot fits about 3.4% more homes on the same land ^[7]. Zillow puts the deficit at 4.7 million units, and it had more than 300,000 empty lots listed on its site in June ^[9].

The evidence shows a pipeline running thin against a pre-pandemic line. The analysis does not measure whether the 4.7 million-unit deficit is growing, and Zillow's own wording is that a thinner pipeline could deepen the shortage ^[12]. Zillow's site also connects new-construction shoppers directly with builders ^[13]. The picture could turn out differently in three ways. The 2016-2020 trajectory may overstate what Sun Belt markets need after their inventory surge. A 1.7% decline can turn into growth within a reading or two. And coastal gains from low bases could keep compounding. In my view the pipeline is short by about 340,000 permits a year against trend, and faster builds cut the delay before that gap turns into fewer finished homes ^[2][3]. That view is wrong if Austin and San Antonio absorb their inventory while permits there stay low and prices do not tighten.
