Base wage and fringe benefits: $57.93 + $39.12
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 $97.05 or more.
| Basic hourly rate (taxable wage) | $57.93 |
| Health and welfare | $15.30 |
| Pension | $9.32 |
| Vacation and holiday (footnote a) | $6.40 |
| Training | $0.72 |
| Other payments | $7.38 |
| Total straight-time hourly rate | $97.05 |
Straight time covers an 8-hour day.
When does this rate change?
- A project pays the rates in effect on its bid advertisement date for the life of the job, plus any increase DIR set in advance (DIR FAQ).
- DIR issues new determinations on February 22 and August 22, and they take effect 10 days later. This rate is from determination C-20-X-1-2026-2, issued August 22, 2026; DIR's expiration date for it is December 31, 2026.
Scheduled increases
DIR has already set these increases. Work on or after each date is paid the higher rate. DIR often leaves part of an increase "to be allocated to wages and/or employer payments" and confirms the split when it comes due, and it can reduce a scheduled increase in a later notice, so check DIR's increase page before you pay it.
| Takes effect | Increase per hour | Total after increase |
|---|---|---|
| January 1, 2027 | +$2.96 | $100.01 |
The double asterisk after DIR's expiration date means the next rate is already set. If the work runs past that date you have to pay the new rate, and DIR says to build it into contracts signed now (DIR FAQ, Q8).

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 $97.05. 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.
