How to Get a DIR Number in California: Requirements and Renewal

To get a DIR number in California, register as a public works contractor through the Department of Industrial Relations online portal at dir.ca.gov, submit your business and insurance details, and pay the $400 annual fee. Credit card payments process within 24 hours; checks and other methods can delay activation by up to eight weeks.¹

The number itself is straightforward to obtain. The compliance obligations that come with it are where contractors get into trouble, so treat registration as the start of a workflow, not a one-time task.

Who Needs to Register

Every contractor and subcontractor performing work on a California public works project must hold an active DIR registration. That includes sole proprietors, brokers, and firms that don’t directly employ workers on site. Employers hauling materials to a public works location, including ready-mixed concrete or paving and grading materials, must also be registered.²

The requirement runs down the whole contracting chain. A general contractor can’t list an unregistered sub in a bid, and an unregistered sub can’t set foot on the job. Expect any prime contractor to ask for proof of your registration before bringing you on.¹

Small Project Exemptions

Not every publicly funded job triggers the requirement. If you work exclusively on new construction, alteration, demolition, installation, or repair projects valued at $25,000 or less, you’re generally exempt. For maintenance-only work the threshold is $15,000 or less. The exemption disappears the moment you take on a project above those amounts, so contractors who occasionally cross into larger public work still need to register.

What to Have Ready Before You Apply

Missing any one of the following will stall your application, so pull it together before you open the portal:

Legal business name and physical address, matching your official business records.
Tax identification: a Federal Employer Identification Number for most businesses. Sole proprietors can use a Social Security Number or Individual Taxpayer Identification Number.
Your California Contractors State License Board (CSLB) license number, if your trade requires one.
Workers’ compensation insurance details, including carrier name, policy number, and effective dates. California requires every employer with one or more employees to carry coverage. Sole proprietors with no employees are not required to carry a policy, though they can purchase one to cover themselves.
A business email address and phone number for correspondence.

Eligibility Conditions That Can Block Approval

Paying the fee is not enough. DIR screens applicants against a short list of disqualifiers, and you must clear all of them:

No delinquent wage or penalty assessments owed to any employee or enforcement agency.
No current federal or state debarment from public contracting.
No prior violation of the registration requirement that would bar a new application.

Contractors caught violating the registration requirement twice within 12 months can be disqualified from all public works for up to 12 months at a time.¹

Completing the Online Registration

Registration happens through the Public Works Contractor Registration portal on the DIR website. First-time applicants create a new account, then enter the business, tax, license, insurance, and contact information listed above into the online form.

After the form, you pay. DIR offers three registration terms:

One year: $400
Two years: $800
Three years: $1,200

Every registration runs on the state fiscal year, July 1 through June 30, regardless of when you sign up. The fee is nonrefundable.¹

Payment method drives your timing. Credit card payments process within 24 hours. Checks and other methods can push activation out by up to eight weeks, during which you cannot legally bid on or perform public works. If you’re racing a bid deadline, pay with a card.¹

Once active, you can verify your status and print proof of registration for bid submissions using the DIR’s Public Works Contractor Registration Search tool.

What Registration Commits You To

The DIR number is a gateway, not a finish line. The moment you take on a public works job, three ongoing obligations apply.

Prevailing Wage

Every worker on the project must be paid the prevailing wage for their craft and location, as determined by the DIR Director. Rates are typically based on local collective bargaining agreements and vary by trade and county. Look up the applicable rates for your project through the DIR’s prevailing wage determination tool at dir.ca.gov.³

Electronic Certified Payroll Reporting

All registered contractors and subcontractors must submit electronic certified payroll records to the Labor Commissioner at least monthly, or more often if the contract requires it. You’ll use the DIR’s eCPR system, and you have to join each specific project in the system before you can submit records for it.⁴ Miss the monthly deadline by more than 14 days and the Labor Commissioner can impose $100 per day, up to $5,000 per project.⁵ Set a calendar reminder. This is the obligation most likely to sneak up on a contractor doing their first public works job.

Apprenticeship

If your project involves apprenticeable trades, you must employ apprentices at a ratio of at least one hour of apprentice work for every five hours of journeyman work. Before starting, notify an applicable apprenticeship program with your estimated journeyman hours, number of apprentices, and approximate work dates. You also contribute to the California Apprenticeship Council at the prevailing rate for your project area. Contracts under $30,000 are exempt.⁶

Renewing to Keep the Number Active

Registrations expire on June 30 every year regardless of when you first registered. The renewal window opens May 1, giving you two months to renew without a gap.⁷ A lapse, even a brief one, means you cannot legally bid on or perform public works until the registration is active again.

Late renewals carry penalties that scale with how late you are. An accidental lapse renewed between July 1 and September 30 costs $400 on top of the fee. If the lapse wasn’t accidental, or if you renew after September 30 and performed any public works while unregistered, the penalty jumps to $2,000.¹

Update your record through the online portal any time business details change, including a new workers’ compensation carrier, a new address, or a different contact person. Awarding bodies and labor compliance officers check these records.

What Happens If You Skip Registration

Working public works without an active DIR number stacks penalties on top of each other. A first-time registrant who bid on, was awarded, or worked on a public works project within the previous 12 months pays a $2,000 penalty on top of the registration fee.¹

On top of that, the Labor Commissioner can assess a separate civil penalty of $100 per day for every day of unregistered work, up to $8,000. A general contractor or higher-tier sub who hired an unregistered subcontractor faces $100 per day for each day that sub worked, up to $10,000. The Labor Commissioner can waive the penalty for a first-time, unintentional violation that didn’t interfere with enforcement. The Labor Commissioner can also issue a stop order halting all work on the project, and ignoring a stop order is a misdemeanor punishable by up to 60 days in county jail, a fine of up to $10,000, or both.⁸

Given how quick and inexpensive registration is compared to those consequences, get the number before you bid, and renew before June 30 every year you plan to keep working in public works.
