Contra Costa County concrete licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 142 active C-8 concrete licenses in Contra Costa County, 6 of them registered in Oakley. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Oakley license has been held 19 years, and the longest-standing one dates to 1988. California law requires workers' compensation cover for C-8 licensees, so it is a legal baseline rather than a way to tell two contractors apart: 5 of Oakley's 6 licenses (83.3%) carry a current policy in CSLB's file, and we do not rank on it. The contractor bond is not a signal here: 142 of the county's 142 licenses carry the same $25,000 bond California sets by statute. 14 county licenses reach their expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.
