Base wage and fringe: $55.00 + $31.42

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 $86.42 or more.

Basic hourly rate (taxable wage)	$55.00
Health and welfare	$13.00
Pension	$11.84
Vacation and holiday	$5.00
Training	$0.65
Other payments	$0.93
Total straight-time hourly rate	$86.42

Straight time covers an 8-hour day.

Davis-Bacon roofer 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).

Footnotes on this rate

DIR's footnotes, in DIR's words. Several change the rate itself: zone pay, a percentage added to the total, or which overtime hours get which rate.

L Rate applies to the first 4 daily overtime hours and the first 12 hours worked on Saturday; all other time is paid at the Sunday and holiday overtime hourly rate.
AV Applies to the first 12 hours worked on Saturday. All other overtime is paid at the Sunday/holiday rate. In the event that conditions over which the individual employer has no control (i.e., adverse weather, project delays, logistical problems, general contractor or owner requirements, etc.) on one or more days during the regular work week prevent employees from working, then work is to be performed on Saturday, when available, at straight time rates.

DIR's other marks: # means an apprenticeable craft, * means in effect until superseded, ** means the next rate is already set.

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 $86.42. 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.
