San Luis Obispo County general building licensure at a glance
California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 1,381 active B general building contractor licenses in San Luis Obispo County, 101 of them registered in Los Osos. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Los Osos license has been held 20 years, and the longest-standing one dates to 1974. 19 of Los Osos's 101 licenses (18.8%) 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: 1,381 of the county's 1,381 licenses carry the same $25,000 bond California sets by statute. 122 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.
