California prevailing wage, explained

What it is

Prevailing wage is a minimum hourly rate the state sets for each construction trade, in each county, for public works. It is not the same as minimum wage and it is usually a lot higher. The rate has two parts: a base hourly wage and an hourly fringe amount that covers benefits. You pay both. The Department of Industrial Relations, the DIR, publishes the rates by classification and county and updates them regularly.

The reason it exists is simple. The government does not want public contracts won by whoever can pay their crew the least. So on public work, everyone pays the same set rate, and contractors compete on efficiency and overhead instead of on cutting wages.

When it applies

The short version: if public money is paying for the work, plan on prevailing wage. Cities, counties, school districts, water districts, the state, transit agencies, all of it. There are small-dollar thresholds below which it does not apply, and a few narrow exemptions, but they are smaller than people hope. The solicitation will say whether the job is a public work subject to prevailing wage. If it says so, believe it and price it in.

Private work for a private owner is generally not covered. The gray area is mixed-funding projects, where some public money is involved. When in doubt, assume it applies and verify.

Step 1: Register with the DIR

Before you bid public work, you and any subcontractors must register with the DIR. It is an annual registration with a fee, done online. An unregistered contractor cannot legally bid or be listed on most public works, and agencies do check. Renew it every year. A lapsed registration at bid time is an easy way to get knocked out.

Step 2: Pay the right rate to the right classification

Each worker gets paid the prevailing rate for the classification of work they actually perform, not their job title. A laborer doing electrical work may need to be paid at the electrician rate for those hours. The classifications are specific, and misclassifying someone to pay a lower rate is exactly the kind of thing that triggers an audit and penalties.

Pay attention to overtime and shift rules too. On public works, overtime often kicks in differently than you are used to, and the determinations spell out the multipliers.

Step 3: File certified payroll

This is the paperwork that trips up new public-works contractors. Every week you submit certified payroll records: each worker, their classification, hours worked, and the exact wage and fringe paid, signed and certified as true. Most contractors file electronically through the DIR system.

Two things to know. First, the records are public and the agency reviews them. Second, the penalties for late, missing, or inaccurate certified payroll are separate from any wage violation. You can pay everyone correctly and still get penalized for sloppy or late reports. Build the time for this into your overhead.

Step 4: Handle apprenticeship

On most public works above a threshold, you have to make a good-faith effort to employ apprentices from a state-approved program, usually at a set ratio of apprentice hours to journeyman hours. There are request forms you file with the apprenticeship committees before and during the job. Skipping this is another common penalty trap, even for contractors who pay wages correctly.

The penalties, so you take it seriously

Underpay prevailing wage and you owe the back wages plus a penalty assessed per worker, per day of violation. Those daily penalties stack fast on a job with a crew. Serious or repeat violations can get you debarred, locked out of public works entirely for a set period, which for a contractor who relies on public work is close to a death sentence. None of this requires bad intent. Honest mistakes get penalized the same as deliberate ones.

The takeaway for pricing

Prevailing wage is not a reason to avoid public work. The work is steady and the agency always pays. It is a reason to price public jobs as their own thing, with the higher labor cost, the certified-payroll overhead, and the apprenticeship effort all built into your number from the start. Contractors who bid public work at their private-job labor rates do not just earn less. They lose money on the jobs they win.
