Alameda County low voltage licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 155 active C-7 low voltage systems licenses in Alameda County, 4 of them registered in San Lorenzo. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median San Lorenzo license has been held 4 years, and the longest-standing one dates to 1993. 1 of San Lorenzo's 4 licenses (25.0%) carries 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: 155 of the county's 155 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.
