How this market compares
San Ramon against every other city in California on the same measure.

Cities with fewer than 500 businesses in total are left unranked.
This industry takes up a far larger slice of the local business base than it does statewide. A crowded market: expect established competitors and price pressure, but also a deeper pool of businesses to buy.
