Commercial Building Contractors

The 40,344 Commercial building contractors in the US coordinate resources and manage the building process for industrial, commercial, and institutional projects. About 72% of contractors are sole proprietors or entities without workers on payroll. Most commercial building contractors rely heavily on subcontractors.

Dependence on Subcontractors

Commercial building contractors are dependent on subcontractors for specialized activities, such as electrical, plumbing, or mechanical work.

Competitive Pricing Environment

Most commercial construction jobs are competitive bidding situations, and price is a major deciding factor in which commercial contractor obtains the job.

Sep 6, 2026 - Construction Spending Declines

• The total value of nonresidential construction put in place rose 0.1% in July 2026 compared to the prior month, according to the US Census Bureau. Spending for most types of nonresidential structures was uneven in July. Office projects, which include data centers, saw the strongest growth with a 2.9% rise in July over June, followed by communication (+0.4%) and public safety (+0.1%). Educational and healthcare project spending declined by 0.4% and 0.5%, respectively, while amusement and recreation spending dropped by 0.3%. Commercial and lodging spending were flat, while manufacturing projects saw a 1% decline. The Associated General Contractors of America (AGC) said just three segments are propping up the construction sector: data centers, power projects, and highways. However, the AGC suggests these three areas are under pressure from labor shortages, political headwinds, and a lapse in highway funding.
• The Wall Street Journal reports that investors are increasingly buying aging hotels that need renovations as property prices fall and new hotel construction slows. According to MSCI data cited by the Journal, US hotel sales rose 28% in the first half of 2026 compared with a year earlier. Lower borrowing costs, improving hotel revenue, and discounted property prices are helping attract buyers, while major hotel brands are becoming more aggressive about enforcing renovation requirements. Many owners have delayed upgrades because of debt burdens and limited cash. The trend could benefit commercial construction firms by generating more renovation work for guest rooms, lobbies, restaurants, meeting spaces, and building systems. New hotel room supply is growing just 0.5% this year, well below the historical average of 1.6%, making acquisitions and renovations more attractive than new development.
• Construction robotics are attracting major investment as contractors seek automation to ease labor shortages and handle increasingly large workloads, according to Construction Dive. Bedrock Robotics, Gravis Robotics, and FieldAI have raised nearly $1 billion combined, backed by investors including SoftBank, Nvidia, and Bill Gates. Adoption also appears to be accelerating, with a 2026 BuiltWorlds survey finding that contractor use of robotics increased 45% year over year, while pilot programs nearly tripled. Robots are already performing repetitive tasks such as layout, drilling, painting, bricklaying, and drywall work, although it is still early days for broader adoption. Experts say successful deployment will depend heavily on high-quality construction data. Large integrated contractors and specialized trade firms may be best positioned to invest directly, while midsized contractors are more likely to adopt proven technologies after their capabilities and financial benefits become clearer.
• US construction and engineering spending on nonresidential buildings is expected to fall 5% in 2026 after remaining flat in 2025, according to FMI’s third-quarter 2026 North American Engineering and Construction Outlook. Data centers will remain the strongest major growth area, with spending projected to rise 21% amid high demand for AI infrastructure and extremely low available capacity in leading markets. Religious construction is forecast to increase 13%, although growth is concentrated in a small number of large campus projects. Communication spending is expected to rise by 3% as AI-driven network demand and broadband construction activity support growth. Challenges will be most severe in manufacturing, where spending is forecast to fall 17% as semiconductor and battery projects move beyond peak construction phases. Warehouse spending is projected to drop 10% because of fewer recent starts, while lodging spending is expected to decline 9% as development focuses on conversions and luxury projects.
