How many concrete contractors are in California?
The Census Bureau counted 2,036 businesses with employees in California in 2022, in the category “Poured concrete foundation and structure contractors”. That ranks California 1st of 50 states, one of the largest markets in the country, and 9% of the US total. 69% of them have fewer than 10 staff, and 347 have 20 or more.
Together they employ 34,846 people, with an average yearly payroll of $1,277,778 per business. The three busiest counties hold 32% of them, so the work is spread across the state.
