The rate remained the same even though steady job growth continues. The state added 4,000 nonfarm jobs last month, officials said.
Four categories added a total of 24,400 jobs over the month: manufacturing; information; professional and business services; and educational and health services.
Six categories, including construction, financial activities and government, lost 20,400 jobs. Government posted the largest decrease over the month, with 10,300 fewer jobs. One category, leisure and hospitality, was unchanged.
The state still has a long way to go to fully recover from the recession. More than 2 million people in California remain unemployed, but it's down by 185,000 compared to February of last year.
The national unemployment rate also remained unchanged in February at 8.3 percent.
