Los Angeles County tree licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 457 active C-49 and D-49 tree licenses in Los Angeles County, 13 of them registered in Pasadena. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median Pasadena license has been held 13 years, and the longest-standing one dates to 1992. 10 of Pasadena's 13 licenses (76.9%) 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: 457 of the county's 457 licenses carry the same $25,000 bond California sets by statute. 42 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.
