WASHINGTON - U.S. homebuilding dropped more than expected in September as construction activity in the South fell by the most in nearly three years, likely held down by Hurricane Florence.

Other details of the report published by the Commerce Department on Wednesday were also soft. Building permits declined to their lowest level in almost 1-1/2 years. The housing market, which has been a weak spot in a robust economy, has been hobbled by an acute shortage of properties for sale.

Residential investment contracted in the first half of the year and the latest data supports economists’ expectations that housing remained a drag on economic growth in the third quarter.

Housing starts fell 5.3 percent to a seasonally adjusted annual rate of 1.201 million units last month. Data for August was revised down to show starts rising to a rate of 1.268 million units instead of the previously reported pace of 1.282 million units. July’s sales pace was also revised lower.

Starts in the South, which accounts for the bulk of homebuilding, tumbled 13.7 percent last month. That was the biggest decline since October 2015. Hurricane Florence slammed North and South Carolina in mid-September and flooding from the storm probably depressed homebuilding last month.

Building permits fell 0.6 percent to a rate of 1.241 million units in September. That was the second straight monthly decline and left permits at their lowest level since May 2017.

Economists polled by Reuters had forecast housing starts declining to a pace of 1.220 million units last month. Starts surged 29 percent in the Northeast and rose 6.6 percent in the West. They fell 14.0 percent in the Midwest.

U.S. financial markets were little moved by the data.


Economists blame the sluggish housing market on rising mortgage rates, which have combined with higher house prices to make home purchasing unaffordable for some first-time buyers.

The 30-year fixed mortgage rate jumped 19 basis points to 4.90 percent last week, the highest level since mid-April 2011, according to data from mortgage finance agency Freddie Mac. The mortgage rate has risen about 91 basis points this year.

While mortgage rates are still low by historical standards, the rise has outpaced annual wage growth, which has been stuck below 3 percent. House prices have increased 6.0 percent on an annual basis and are being driven by the dearth of properties.

Single-family homebuilding, which accounts for the largest share of the housing market, decreased 0.9 percent to a rate of 871,000 units in September. Single-family homebuilding has lost momentum since hitting a pace of 948,000 units last November, which was the strongest in more than 10 years.

A survey on Tuesday showed confidence among single-family homebuilders rose in October, but builders said “housing affordability has become a challenge due to ongoing price and interest rate increases.”

Permits to build single-family homes rose 2.9 percent in September to a pace of 851,00 units. They, however, remain below the level of single-family starts, suggesting limited scope for a strong rebound in homebuilding.

Starts for the volatile multi-family housing segment plunged 15.2 percent to a rate of 330,000 units in September. Permits for the construction of multi-family homes declined 7.6 percent to a pace of 390,000 units.

With starts and building permits declining last month, housing supply will likely remain tight. That was also reinforced by a 4.1 percent drop in homebuilding completions in September to a rate of 1.161 million units, the lowest level since November 2017.

Realtors estimate that housing starts and completion rates need to be in a range of 1.5 million to 1.6 million units per month to plug the inventory gap.

The stock of housing under construction increased 0.3 percent to more than an 11-year high of 1.129 million units last month. However, multi-family homes accounted for much of the increase.
