San Joaquin County plumbing licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 220 active C-36 plumbing licenses in San Joaquin County, 4 of them registered in Linden. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Linden license has been held 20 years, and the longest-standing one dates to 1987. 2 of Linden's 4 licenses (50.0%) 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: 219 of the county's 220 licenses carry the same $25,000 bond California sets by statute. 26 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.
