San Bernardino County septic licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 73 active C-42 sanitation system licenses in San Bernardino County, 8 of them registered in San Bernardino. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median San Bernardino license has been held 23 years, and the longest-standing one dates to 1976. 5 of San Bernardino's 8 licenses (62.5%) 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: 73 of the county's 73 licenses carry the same $25,000 bond California sets by statute. 11 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.
