Top construction companies in California

California builds at a scale few places match. The state is home to some of the largest contractors in the country — global engineering-and-construction firms, employee-owned builders that have worked the same markets for generations, and specialists that pour the highways, wire the data centers, and stand up the solar farms behind California’s growth.

This post ranks the top construction companies headquartered in California by their position on Engineering News-Record’s 2026 Top 400 Contractors list, which ranks firms by their 2025 construction revenue. Every revenue figure and rank below comes from ENR’s published list; sources are linked throughout.
