DIR general determination C-MT-261-X-265-2021-1, issued February 22, 2021 and still current in DIR's 2026-2 release. Checked against dir.ca.gov on October 24, 2026.
DIR's expiration date for this determination was March 31, 2021. DIR hasn't issued a replacement, so this rate still applies, which is what the single asterisk on DIR's table means. A project keeps the rates in effect on its bid advertisement date for the life of the job.
Base wage and fringe benefits: $25.90 + $23.33
The basic hourly rate is the taxable wage. The other lines, the fringe benefits DIR calls employer payments, are what DIR expects the employer to pay into health, pension and other plans for each hour worked. An employer can pay part of that as extra wages instead, as long as the total per hour stays at $49.23 or more.

Are you being paid this rate?
Add your hourly wage to what your employer pays into health, pension and other plans for you, and compare it with $49.23. Plan payments only count if the money goes into the plan; your pay stub won't show them, but plan statements will. The training amount goes to the California Apprenticeship Council or an apprenticeship program, not to you. Check a week of pay.
Contractors on most public works jobs file certified payroll with the state, and anyone can look it up in DIR's CPR public search. If your total comes up short, you can file a public works complaint with the California Labor Commissioner.
