Occupational Group 481
In the California 2005 PD Rating Schedule, occupational group 481 covers jobs such as AIR CONDITIONING INSTALLER SERV., WINDOW UNIT, BRICKLAYER, and BRICKLAYER APPRENTICE. Your occupational group sets the variant applied to each impairment, which adjusts the standard rating up or down before the age adjustment. Here a physical impairment raises the rating.

Group 481 rating FAQ
What is occupational group 481 in California workers’ comp?
Occupational group 481 is one of the 45 groups in the 2005 Permanent Disability Rating Schedule. It covers jobs such as AIR CONDITIONING INSTALLER SERV., WINDOW UNIT, BRICKLAYER, and BRICKLAYER APPRENTICE. The group number sets the “occupational variant” applied to each impairment, which adjusts the standard rating up or down (PDRS Sections 4 and 5).
Does my occupational group change my permanent-disability rating?
Yes. After the whole-person impairment is converted to a standard rating, the occupational group applies a variant (C–J) that raises or lowers it before age adjustment. For group 481, a physical impairment such as a spine or knee injury raises the rating relative to the standard.
How much does group 481 adjust a 20% standard rating?
Spine: 27% (+7); Shoulder: 25% (+5); Knee: 27% (+7); Wrist / carpal tunnel: 29% (+9); Grip / pinch strength: 25% (+5); Psychiatric: 25% (+5); Hearing loss: 22% (+2); Respiratory / lungs: 25% (+5).
