San Francisco County masonry licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 15 active C-29 masonry licenses in San Francisco County, 15 of them registered in San Francisco. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median San Francisco license has been held 29 years, and the longest-standing one dates to 1954. 11 of San Francisco's 15 licenses (73.3%) 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: 15 of the county's 15 licenses carry the same $25,000 bond California sets by statute. 0 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.
