U.S. construction starts fell sharply in August 2026, but the decline was a monthly pullback rather than a reversal of the broader expansion. Dodge Construction Network reported that total starts dropped 24.8% to a seasonally adjusted annual rate of $1.34 trillion after an unusually strong, megaproject-heavy July. Through the first eight months of 2026, however, total starts were still 15.2% above the same period a year earlier, and starts over the 12 months ending in August were up 14.5%.
The apparent contradiction is resolved by separating the time window, sector and measurement. Nonresidential and nonbuilding projects are driving the gains, while residential starts are contracting. These are dollar values of projects entering construction, not construction spending already completed, housing-unit counts or proof that every part of the industry is expanding.

Why did construction starts fall in August if growth remained positive?
August was a month-to-month retreat after July’s exceptional increase. Sarah Martin, director of economic research at Dodge Construction Network, said that “after a pop in activity last month, construction starts largely normalized throughout August.” Dodge characterized July’s jump as heavily influenced by megaprojects, so a large August decline was possible without wiping out gains accumulated earlier in the year.
The August figure is a seasonally adjusted annual rate (SAAR) of $1.34 trillion. A SAAR converts one month’s pace into a hypothetical full-year rate; it is not the dollar value of projects started during August alone and should not be read as completed construction spending. Monthly starts can swing when one or two very large projects enter the database, which is why longer comparison periods provide a steadier view of momentum.

What each time window says
| Measure | Result through August 2026 | What it is useful for |
|---|---|---|
| August versus July | Total starts down 24.8%, to a $1.34 trillion SAAR | The latest change, highly sensitive to timing and megaprojects |
| Year to date versus the same period in 2025 | Total starts up 15.2% | Progress across the first eight months |
| Trailing 12 months versus the prior 12 months | Total starts up 14.5% | A less seasonal measure of current direction |
For a business assessing the pipeline, the year-to-date and trailing-12-month comparisons are better indicators of cumulative growth. The monthly result remains important as the newest signal, but it should be interpreted alongside those broader windows.
Which construction sectors are growing, and which are shrinking?
Growth is concentrated outside residential construction. Dodge’s August 2026 data show a widening split among residential, nonresidential and nonbuilding starts.

| Nonresidential | Up 23.4% | Up 17.9% |
| Nonbuilding | Up 22.2% | Up 27.6% |
| Residential | Down 1.8% | Down 2.4% |
Nonbuilding work includes major infrastructure and utility-related projects, while nonresidential covers commercial, industrial and institutional buildings. Their strong performance more than offset the residential decline in the aggregate dollar series.
Commercial, manufacturing and institutional work are not moving together
Even the nonresidential category contains opposing trends. Year to date, Dodge reported commercial and industrial starts up 47.7%, while institutional starts were down 3.9%. Over the trailing 12 months, commercial starts were up 48.6%, manufacturing starts rose 2.8%, and institutional starts fell 4.3%.
That composition matters. A headline describing nonresidential growth does not mean schools, hospitals and other institutional projects are expanding at the same rate as commercial work. Dodge linked continuing gains to concentrated activity in areas such as data centers, semiconductor facilities and energy projects, while also describing subdued sectors, labor shortages and accelerating material prices. Those are Dodge’s interpretations of the pattern, not a guarantee that every project type or region shares the same conditions.

What does “construction starts” measure?
Dodge’s series measures the dollar value of projects entering the construction pipeline. It is not a count of projects, a measure of floor area, a tally of housing units or a record of money already spent. Large projects can therefore raise the dollar total substantially even when the number of starts or the amount of building space is flat.
Why square footage can tell a different story
For full-year 2025, total starts increased 5.4% from 2024. Nonresidential starts rose 4.5%, residential starts fell 4.8%, and nonbuilding starts climbed 18.7%. At the same time, building starts measured in square footage declined 4.7%. Dodge identified nonbuilding construction and data centers as primary contributors to the dollar-value increase.
The combination shows why readers should name the measure before drawing a conclusion. A smaller number of very expensive infrastructure or technology projects can lift dollar value while total building area declines.
How this differs from Census housing data
The U.S. Census Bureau’s New Residential Construction program tracks housing units authorized, started, under construction and completed. It excludes HUD-code manufactured homes. Those unit counts answer a different question from Dodge’s dollar-value project-start series, so the two sources should not be combined as though they were interchangeable indicators of construction activity.
Which comparison should you use to judge momentum?
Use the comparison that matches the decision you are making:
Also popular on Amazon
- For the newest turning point: check the monthly change, while allowing for timing effects and large individual projects.
- For progress during 2026: use the year-to-date change through August.
- For an underlying pace with less seasonality: use the trailing 12-month comparison.
- For housing demand: consult housing-unit measures, such as the Census series, rather than substituting a total construction-dollar figure.
- For market mix: separate residential, nonresidential and nonbuilding, then examine commercial, manufacturing and institutional subcategories.
Reading all three time windows together prevents a one-month normalization from being mistaken for a collapse, while the sector breakdown prevents nonresidential or nonbuilding strength from being generalized to residential construction.
What does the August result mean for contractors and suppliers?
The data point to an active but uneven pipeline. Firms exposed to commercial, data-center, semiconductor, energy and other nonbuilding work may see stronger opportunities than firms dependent on residential or institutional starts. However, a project entering the starts series is an early pipeline event; it does not establish when work will reach a particular subcontractor, how quickly it will be funded or whether material and labor constraints will delay execution.
Planning should therefore track project type, geography, expected start date and procurement status rather than relying on the national total alone. Dodge’s reported labor shortages and rising material prices are relevant operating constraints even while aggregate dollar starts grow.

Not by itself. The 24.8% monthly decrease followed an unusually strong July, while total starts remained up 15.2% year to date and 14.5% over the latest 12 months. A sustained downturn would require deterioration across longer comparison periods and across the sectors currently supporting growth, not just one volatile monthly reading.

The more precise conclusion is that construction activity cooled in August, but the broader starts trend remained positive and highly concentrated. Residential construction was contracting, institutional work was declining, and large nonresidential and nonbuilding projects were carrying the aggregate expansion.

Frequently Asked Questions
What is a seasonally adjusted annual rate in construction reports?
A seasonally adjusted annual rate takes one month’s seasonally adjusted pace and expresses it as if that pace continued for a full year. It is an analytical annualized rate, not a cash total for the month and not a forecast that the same volume will actually occur over the next 12 months.
Can a construction start be canceled after it appears in the data?
A starts series identifies projects entering the pipeline; it does not guarantee final completion. Financing, permitting, redesign, labor availability or market conditions can change a project’s timing or scope after the initial start is recorded.
Why might infrastructure growth matter more to the dollar total than housing starts?
Infrastructure, energy and technology facilities can carry very high individual project values. A relatively small number of such projects can therefore move the national dollar aggregate more than many lower-value housing projects.
