The 2026 Construction Cost Index
In 2026, U.S. construction costs range from about $2.5 per square foot for a asphalt paving to $2,000 per square foot for a data center. Most commercial buildings fall between $150 and $600 per square foot, all-in and excluding land. The index below gives a low-to-high range for 33 building types plus six priced per bed, unit, or space.

Some building types are measured by capacity rather than floor area — the number that actually governs the budget.
Methodology
Each figure is the all-in construction cost per square foot for a completed building of that type, drawn from Buildermuse's individual cost breakdowns. Ranges reflect the spread between a value-tier build in a low-cost labor market and a high-specification build in an expensive metro. Figures are hard-cost plus typical soft costs; they exclude land. Sources include contractor-reported project data, RSMeans-style assemblies, BLS producer price indexes for materials, and published bid tabulations. Refreshed quarterly.

Frequently Asked Questions
How much does it cost to build per square foot in 2026?
It depends entirely on building type. In 2026, U.S. construction runs from about $2.5 per square foot for a asphalt paving to $2,000 per square foot for a data center. Most commercial buildings land between $150 and $600 per square foot. The table above gives a range for 44 building types.
What is the average commercial construction cost per square foot?
For a mainstream commercial building — retail, office, or light institutional — expect roughly $150 to $600 per square foot all-in for 2026, excluding land. Restaurants, medical, and public-safety buildings sit at the high end because of mechanical, electrical, and code requirements; warehouses and metal buildings sit far below it.
Do these figures include land and design costs?
They include hard construction cost plus typical soft costs like design and permitting. They exclude land acquisition, which varies too widely by location to average. Site-specific factors — union labor, seismic zones, supply-chain delays — push a project toward the high end of each range.
