San Diego County well drilling licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 29 active C-57 well drilling licenses in San Diego County, 5 of them registered in Escondido. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Escondido license has been held 24 years, and the longest-standing one dates to 1991. 4 of Escondido's 5 licenses (80.0%) carry current workers' compensation cover in CSLB's file. That is employee injury cover, not liability insurance, and a blank usually means an owner-operator with no employees - lawful, and not a mark against anyone. The contractor bond is not a signal here: 29 of the county's 29 licenses carry the same $25,000 bond California sets by statute. 2 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.
