You may never purchase a gallon of diesel, but its rising price could still hit you where it hurts most: your housing costs.

As diesel prices climb nationwide, the effects are reaching Atlanta’s housing market, increasing construction expenses, threatening affordable housing developments and potentially driving up rents and home prices. The increases, fueled in part by disruptions to global oil supplies following the conflict with Iran earlier this year, are adding another financial challenge to an already expensive construction industry.

According to the U.S. Energy Information Administration, the national average diesel price reached $6.529 per gallon in September before falling to $6.382 on Sept. 28, approximately 70% higher than a year earlier.

Patrick Chopson, co-founder and principal architect at Atlanta-based architecture firm cove, explained that diesel plays a much larger role in housing construction than most people realize.

“Every construction project has a budget, and so every time the diesel goes up, each specific component, like let’s say wood studs or framing or concrete or the site … all those things add cost,” Chopson said.

Diesel affects construction expenses in five major ways: producing raw materials, transporting building supplies, operating heavy equipment, moving workers and machinery to construction sites and hauling away debris.

For example, diesel-powered machinery helps harvest lumber, trucks transport materials and excavators prepare construction sites. Each stage becomes more expensive when fuel prices rise.

Another expense comes from what contractors call “mobilization,” the cost of transporting workers, equipment and materials to a job site.

“Every single step they have to start adding a fuel surcharge on that,” Chopson said. “But then if you do that across every piece of the building … you can actually see it showing up..really fast.”

These increases come as the construction industry faces broader financial pressures. According to ConstructConnect, construction input costs have increased more than 40% since early 2020.

Meanwhile, an April 2026 National Association of Home Builders survey found that 62% of builders reported suppliers raising material prices because of higher fuel costs.

For developers, these accumulating expenses can determine whether a housing project moves forward at all.

Chopson explained that when construction costs rise, developers may abandon projects or shift toward more expensive housing to recover their investments.

“Some of them don’t ever happen because you just can’t do it,” Chopson said. “But it also means that projects that otherwise would have been lower rent suddenly have to maybe make a jump to the next tier of more expensive housing.”

That creates additional challenges for Atlanta residents already struggling with housing affordability.

When fewer apartments and homes are built, the limited supply can place upward pressure on rents, particularly affecting lower-income households and first-time homebuyers.

Chopson pointed to stalled developments around Atlanta as examples of how difficult economic conditions can prevent projects from moving forward, leaving construction sites unfinished and potential housing units unbuilt.

However, architects and developers have some opportunities to reduce costs.

Chopson said his firm uses analytical tools to evaluate building materials, structural designs and construction methods, identifying combinations that require fewer resources without compromising the building.

Even relatively small design changes can reduce the amount of concrete, steel and transportation needed, helping projects remain financially feasible.

There may also be some relief ahead. The US Energy Administration’s October outlook projects diesel prices averaging approximately $4.50 per gallon in 2027, although that forecast remains subject to changing global conditions.

For a more detailed breakdown of how rising diesel prices affect construction costs and the broader industry, Chopson explores the figures and trends in an article published on cove’s website. 

Still, Chopson believes addressing housing affordability requires more than waiting for fuel prices to fall. He encouraged Atlantans to participate in local elections, attend City Council and neighborhood planning meetings and speak up about development decisions.

“The more we do that, the more likely it is that we can … affect public policy,” Chopson said.

For Atlanta residents, the connection between diesel and housing may begin far from home, but its consequences can reach their monthly budgets. And while fuel prices remain beyond most residents’ control, Chopson argues that the decisions shaping Atlanta’s housing future do not have to be.
