The U.S. Department of Commerce's Census Bureau reported on Tuesday that the annualized pace of new home starts tumbled to 1.239 million units in July, significantly undershooting the market's expectation of 1.35 million and marking a sharp 12.4% drop from June's revised figure of 1.415 million. This follows an upward revision to June's data, which had shown a 19.7% month-over-month surge. The latest reading fell short of every economist's projection—the estimates from 49 analysts spanned a range of 1.30 million to 1.483 million units—and came in far worse than the anticipated 5.9% decline. After a brief rebound in early summer, residential construction activity is now cooling at a pace that has caught many off guard.

Single-Family Homes Lead the Decline: 808,000 Units Mark the Lowest Since November 2022

Looking at the breakdown, single-family homes, which account for the largest share of residential construction, were the primary driver of this downturn. In July, single-family housing starts fell 9.9% month-over-month to an annualized rate of 808,000 units, the lowest level seen since November 2022. This marks the weakest month for single-family construction since 2022. The pullback in multi-family units was even more pronounced. Following a significant surge in the previous month, multi-family starts dropped nearly 17% month-over-month in July, indicating that the backlog of apartment and condominium projects is being absorbed quickly while new project launches have failed to keep pace. Regionally, housing starts declined across the South, Midwest, and West, with only the Northeast showing improvement, buoyed by multi-family project advancements.

Building Permits Unexpectedly Rise: A Rare Divergence Between Starts and Permits

In stark contrast to the gloomy starts data, building permits—a leading indicator of future construction activity—rose 5% month-over-month in July to an annualized rate of 1.443 million, far exceeding the market's forecast of 1.37 million. Within this, single-family permits increased 2.5% to 894,000 units, while permits for multi-family buildings with five or more units surged 9.1% to 490,000 units. This notable divergence between starts and permits sends a mixed signal. The uptick in permits suggests that developers still hold some confidence in future demand, as they continue to file applications for upcoming projects. However, the steep drop in starts implies that builders are facing mounting obstacles between securing a permit and breaking ground. That obstacle is financing costs. Even with permits in hand, the financial viability of projects continues to deteriorate under the current high-interest-rate environment.

The Double Squeeze of High Rates and High Prices

The sharp cooling in residential construction in July stems from persistently weakening demand on the consumer side. Rising mortgage rates are the primary dampening factor. Since the onset of the Iran conflict, mortgage rates have climbed steadily. According to Freddie Mac, the average rate on a 30-year fixed mortgage rose to 6.81% for the week ending August 14, reaching its highest level in over a year. Overall mortgage application volume fell 2.9% from the prior week and was down 5% year-over-year. Earlier, on July 30, the 30-year fixed rate had already hit 6.66%, a one-year high at that time. The impact of high rates on homebuying intent is systemic. The National Association of Home Builders' housing market index for August ticked up slightly to 35, but it remains well below the 50 breakeven threshold. Builder confidence stays depressed, which is reflected in the ongoing contraction in starts. Meanwhile, elevated home prices and rising construction costs continue to squeeze developers' profit margins. Prices for residential construction inputs are 6.2% higher than the same period last year. With both financing and building costs elevated, builders are increasingly cautious about launching new projects.

Home Depot's Warning: Big-Ticket Renovation Projects Remain 'Frozen'

The weakness in the residential construction market is also evident in the earnings of home improvement retail giants. The world's largest home improvement retailer, Home Depot (HD.US), released its second-quarter results on the same day, providing further evidence of the housing market's true state. Home Depot reported second-quarter revenue of $47.86 billion, up 5.7% year-over-year and above analyst expectations. However, this growth was primarily driven by consumer spending on smaller repair and maintenance projects—like repainting a room or adding plants to a garden—rather than large-scale renovations. In the company's earnings call, CFO Richard McPhail stated that the housing market has not yet recovered and that big-ticket renovation projects remain 'frozen.' This assessment aligns with July's data showing single-family starts at their lowest level since 2022—both new construction and major remodeling are stalled by high rates and high costs. Despite a solid quarter, Home Depot maintained its full-year guidance for total sales growth of approximately 2.5% to 4.5%, reflecting management's lack of confidence in the housing market's near-term outlook. Neil Saunders, Managing Director at GlobalData, noted that while spending on smaller projects is encouraging, it is insufficient to offset the broader downturn in the housing market.

Outlook: The Chain Effects of Fewer Projects in the Pipeline

The July data carries multiple implications for the broader economy. The weakening in residential investment could drag on third-quarter GDP growth. More importantly, construction completions are also declining in tandem. The overall pace of housing completions fell to 1.212 million units in July, down from June's 1.333 million. Single-family completions also dropped to their lowest level since 2020. A shrinking pipeline of projects under construction means the supply of new homes available for sale will remain tight in the future. While demand is being suppressed by high interest rates, the contraction on the supply side will further exacerbate the nation's long-standing housing affordability crisis. The only encouraging signal comes from building permits—the 5% increase indicates that developers' expectations for future demand have not completely collapsed. But as one analyst put it: 'A permit is a permit, and a groundbreaking is a groundbreaking—the gap between the two highlights the real constraints builders face.' As long as mortgage rates remain above 6.8% and financing costs show no meaningful decline, the conversion from permits to actual starts will continue to be hampered.
