DIR contractor registration (SB 854): who must register and file

A license is not the same as registration

A valid California contractor's license lets you bid work generally. It does not, by itself, let you bid or perform public work. Since SB 854 (2014) took effect, a separate registration with the Department of Industrial Relations is required, and it is checked independently of licensing status. Contractors who assume an active CSLB license covers them are the ones who find out otherwise at bid opening.

The registration requirement

Labor Code §1725.5 establishes DIR public-works contractor registration: an annual application, a registration fee, proof of appropriate workers' compensation coverage, and confirmation the applicant is not currently ineligible or debarred. Labor Code §1771.1 then makes the point operational — a contractor or subcontractor that is not registered under §1725.5 is not qualified to bid on, be listed as a subcontractor on, or perform work on a public-works contract. Every subcontractor tier on the job needs its own active registration; a general contractor's registration does not extend to its subs.

Registration has to stay active the whole time

Registration is not a one-time gate at bid time — it has to remain active for the entire period work is performed on the project, and it renews annually. A contractor that registers to bid, wins the job, and then lets the registration lapse mid-project during a long job is out of compliance for every day it was lapsed, even though nothing about the actual work changed. This is one of the most common and most avoidable compliance failures on public works, precisely because it has nothing to do with the quality of the work or the accuracy of the payroll — it is a calendar problem.

• Track the registration's expiration date against the project schedule at bid time, not just at contract signing.
• Renew before expiration rather than after — a lapse creates a compliance gap even if it's corrected the same week.
• Confirm every subcontractor's registration status before they start work, and periodically during a long-running job.

The awarding body's separate filing: PWC-100

Contractor registration is only half of it. The awarding body — the public agency awarding the contract — has its own obligation to register the project itself with DIR, using form PWC-100, generally within a short window after the contract is awarded. That filing is what links the project to DIR's system so certified payroll for that specific job can be submitted through eCPR. A contractor with a fully active registration can still hit a filing wall if the awarding body never completed the PWC-100 for the project — worth confirming early rather than assuming it happened.

Small-project exceptions exist, and they're narrow

There is a limited exemption from the registration requirement for certain small maintenance-type work below a dollar threshold set in statute. It is narrow, it does not apply to new construction generally, and the current threshold and exact conditions should be confirmed against DIR's current published guidance rather than assumed — treating a project as exempt without verifying it is a common way to end up unregistered on a job that actually required registration.

What working unregistered actually costs

The consequences are not a slap on the wrist. A bid submitted by an unregistered contractor can be treated as nonresponsive and rejected outright. A contract awarded to, or work performed by, an unregistered contractor exposes both the contractor and the awarding body: the contractor risks losing the ability to be paid for work performed while unregistered, and the awarding body risks its own compliance exposure for having allowed it. Beyond the immediate project, a pattern of unregistered work is the kind of finding that follows a contractor into future bids and can factor into a debarment referral.

Registration lapses are rarely a business decision. They're an expiration date nobody put on a calendar.

The practical checklist

• Confirm DIR registration is active — for the general contractor and every subcontractor — before bid submission.
• Calendar the annual renewal date well before expiration, with a buffer for processing time.
• Confirm the awarding body has filed the PWC-100 for the specific project before assuming eCPR filings will be accepted.
• Re-verify subcontractor registration status on any public-works job running longer than a year.
