How many tree service companies are in California?
The Census Bureau counted 9,325 businesses with employees in California in 2022, in the category “Landscaping services (the Census group that includes tree services)”. That ranks California 2nd of 50 states, one of the largest markets in the country, and 8% of the US total. 79% of them have fewer than 10 staff, and 1,051 have 20 or more.
Together they employ 102,414 people, with an average yearly payroll of $555,280 per business. The three busiest counties hold 32% of them, so the work is spread across the state.
With 38,965,193 residents (Census, July 2023), that is one business for every 4,179 people, against 2,855 nationally: more residents per business than the US average, so each business has more homes to serve.
