California Government Contracts & Bid Opportunities

California is the largest public-sector market in the country, and it also has some of the most specific rules. State opportunities post through a central eProcurement system, transportation work runs through Caltrans, and public-works contractors must register with the Department of Industrial Relations and hold a state contractor license before they bid.
