Rates by sector
Use the national helper medians to frame California budgets for public, specialty or commercial support roles. Allow for onboarding and supervision as well as benefits. Match the wage comparison to the actual helper duties rather than a specialist craft role.
Local Government
Define the public position's support duties. Check recruitment procedures, eligibility, and supervision; budget the complete package beyond this national wage benchmark.
Other Specialty Trade Contractors
Recruit for permitted specialty support tasks. Assess readiness, define supervision and progression, and budget travel, payroll, benefits, and training beyond wages.
Nonresidential Building Construction
Recruit for the commercial support tasks. Assess materials handling and instruction-following; budget supervision, onboarding, payroll, benefits, and scheduling beyond wages.
