DIR lists 7 sheet metal worker rates for each of these counties, from $69.45 to $140.34 an hour. See all of them.
Base wage and fringe: $81.34 + $59.00
The basic hourly rate is the taxable wage. The other lines, usually called fringe benefits, 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 $140.34 or more.
| Basic hourly rate (taxable wage) (footnote I) | $81.34 |
| Health and welfare (footnote BE) | $20.44 |
| Pension (footnote BF) | $35.67 |

Vacation and holiday is $0.00 in DIR's table. Footnote F says where that money is counted.
Straight time covers an 8-hour day.
Davis-Bacon sheet metal worker rates in these counties
The counties share DIR's rates, but not always the same federal wage determination. When a California awarding body runs a federally funded or assisted project, DIR's rates must be paid where they are higher than the Davis-Bacon rates (DIR public works FAQ).

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 |
|---|---|---|
| June 28, 2027 | +$5.40 | $145.74 |
| July 3, 2028 | +$5.60 | $151.34 |
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 $140.34. 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.
