Stanislaus County solar licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 17 active C-46 solar licenses in Stanislaus County, 7 of them registered in Modesto. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Modesto license has been held 11 years, and the longest-standing one dates to 1979. 3 of Modesto's 7 licenses (42.9%) 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: 17 of the county's 17 licenses carry the same $25,000 bond California sets by statute. 1 county license reaches its 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.
