Prevailing wage fringe benefits in California

The Labor Code says "employer payments" where most people say fringe benefits. Section 1773.1(a) makes them part of the per diem wage and lists the kinds that count: health and welfare, pension, vacation, travel, subsistence, apprenticeship or other training programs, worker protection programs under the federal Labor Management Cooperation Act, industry advancement and collective bargaining administrative fees (when a CBA requires them), and "other purposes similar" to those (Labor Code 1773.1).

A payment counts if it is one of three things: a contribution "irrevocably made by the employer to a trustee or third person pursuant to a plan, fund, or program," the actual cost of a benefit the employer has committed to in writing, or a payment to the California Apprenticeship Council (1773.1(b)). The employer can take credit for a plan it pays into "on no less than a quarterly basis," even when the contribution falls outside the pay period (1773.1(d)).

Some payments don't count. Section 1773.1(c) denies credit "for benefits required to be provided by other state or federal law," and the Public Works Manual names paid sick leave required by statute, workers' compensation, unemployment insurance, Social Security and Medicare (section 4.2.1). It also lists a cell phone, a company vehicle, gas reimbursement and a Christmas bonus as benefits that don't count (section 4.2.4.1).

Across all 16,854 straight-time rows in DIR's 2026-2 set that we track, employer payments make up a median of 36% of the total hourly rate. For this laborer row it's 36% as well: $27.67 of $76.87. The full row, with the footnotes and overtime, is on our San Diego laborer page; the source is DIR's San Diego laborer determination.

The Labor Commissioner's manual works an example with an ironworker rate of $36.00 base and $29.735 in permissible employer payments, plus $0.72 for training. It says the $29.735 "may be paid by an employer in full or in part to any category of permissible Employer Payments," so an employer can put $20 into a medical or pension plan "and pay the remainder of $9.735 directly to the workers." Added up, $45.735 to the worker, $20.00 to the plan and $0.72 to the CAC make the $66.455 total (Public Works Manual, section 4.2.1).

Applied to the San Diego laborer row, the four non-training payments come to $26.87 an hour. Here are three ways to pay the same $76.87:

In each version the training $0.80 goes to the Council or an approved program, and the wage stays at or above $49.20. A contractor with a collective bargaining agreement may be bound to pay specific plans at specific rates; the manual's example begins "absent contractual obligations which may apply to a particular contractor."

California treats the basic hourly rate as a floor on its own. Section 1773.1(c) says credits for employer payments "shall not reduce the obligation to pay the hourly straight time or overtime wages found to be prevailing." Paying $5 more into a pension doesn't let an employer pay $5 less in wages. Federal Davis-Bacon rules allow that trade, which is one of the differences covered in Davis-Bacon vs California prevailing wage.

There is one narrow exception, written into both 1773.1(c) and section 1773.8. An increased employer payment that lowers the taxable wage is allowed only if it is made under criteria in a collective bargaining agreement, the wage and payments combined still meet the full prevailing rate for straight time and overtime, and the contribution is irrevocable. DIR prints this condition in many footnotes; Alameda's footnote Q reads that the amount "may vary resulting in a lower taxable basic hourly wage rate, but the total hourly rates for straight time and overtime may not be less than the general prevailing rate." The manual (section 4.2.2) calls both exceptions "extremely limited in scope."

The training column has its own rule. Under Labor Code 1777.5(m)(1), a contractor that employs journeymen or apprentices "in any apprenticeable craft or trade shall contribute to the California Apprenticeship Council" the training amount in the determination, with a credit for amounts paid to an approved apprenticeship program "that can supply apprentices to the site" (Labor Code 1777.5). DIR's Division of Apprenticeship Standards says contributions are due by the 15th of the month after the work, with a CAC-2 form, "for every hour worked by every journeyman and apprentice working in an apprenticeable craft (including overtime)." It adds: "Training Funds cannot be paid to the workers unless it is a non-apprenticeable craft" (DAS public works page).

The manual says the same from the enforcement side: the training contribution "is a distinct obligation of the contractor" and "cannot be satisfied by paying the required hourly contribution directly to the worker" (section 3.3.2.2). The contractor may add the contribution into its bid (1777.5(m)(1)).

The # after the craft name shows which rule applies. Alameda's inside wireman row carries # and a $2.43 training amount, which goes to the CAC or the program. The Northern California teamster determination prints the craft as "TEAMSTER" with no # and lists $1.37 for training on Group 1. For crafts without the mark, the manual says training contributions "should be paid to the worker as wages," or to the training program if a collective bargaining agreement requires it (section 4.2.5.4.3).

The six published columns add up to $129.29, and DIR's total is $131.67. Footnote Q explains the gap: "an amount equal to 3% of the basic hourly rate is added to the total hourly rate and overtime hourly rates for the National Employees Benefit Board." Three percent of $79.25 is $2.38. DIR's footnotes name this fund as the National Employees Benefit Board on some rows and the National Electrical Benefit Fund on others. A 3% footnote of this kind appears on 1,754 of the 16,854 rows we track: 1,131 utility lineman rows, 339 line clearance tree trimmer rows and 284 electrician rows. No other trade carries one.

Two other footnote types change the math. Some say an amount is "included in" another column, like Alameda's F ("included in straight-time hourly rate"), so a $0 in the vacation column means vacation pay sits inside the base rate. Others say a payment is "factored at the applicable overtime multiplier," so it grows on overtime hours; the same wireman row's footnote R does that for a 1.05% Contract Administration Fund amount. About 3,000 of our rows carry a "factored" footnote. The overtime guide works those through.

To price fringe for a whole crew, use the crew cost estimator; to test one pay stub, the pay check tool.

DIR's footnotes call the base the "taxable basic hourly wage rate," and section 1773.8 speaks of employer payments that result "in a lower taxable wage." Money paid into a qualifying plan sits outside that wage; money handed to the worker in place of a plan contribution is paid on the paycheck as wages, as in the manual's $45.735 example. How each item is taxed is set by federal and state tax rules, which DIR's prevailing wage materials don't address.
