Los Angeles WCAB District Office

Where is the Los Angeles WCAB office?

This WCAB office is at 320 W. 4th Street, 9th floor, Los Angeles, CA 90013, phone 213-576-7335.

DWC lists this address inside the Junipero Serra building in downtown Los Angeles. Court is in session from 8:30 a.m. to 12:00 p.m. and 1:30 p.m. to 5:00 p.m., Monday through Friday. The court lobby opens 30 minutes before the morning session and stays open five days a week except on state holidays.

Which cases go to this office?

Venue depends on where you live, where the injury happened, or where your attorney's office is, not simply on a ZIP code tool.

California Labor Code section 5501.5 sets venue for a workers' compensation case. You, or a deceased worker's dependent, can file where you live, where the injury happened (or, for a cumulative injury, your last exposure), or where your attorney keeps a principal office. If you use the attorney's-office venue, the employer has 30 days to object, and the case then moves to your residence or injury county instead. If no WCAB office sits in the right county, the case goes to the nearest one. DWC's ZIP code locator can point you toward an office, but it is a convenience tool; it does not decide venue, and your hearing notice is what actually names your office.

DWC's ZIP code listing for WCAB filings assigns the cities below to the Los Angeles office:

• Alhambra
• Altadena

• Baldwin Park
• Bell
• Bell Gardens

• El Monte
• Glendale
• Huntington Park
• Maywood
• Monrovia
• Montebello
• Monterey Park
• Norwalk
• Pasadena
• Pico Rivera
• Rosemead

• South Pasadena

Addresses near these cities are not all routed the same way, and some fall under a neighboring office instead. When you are unsure, compare the Los Angeles and Pomona offices or check the Van Nuys and Pomona district office pages.

What happens there?

The office holds workers' compensation hearings, and its Information and Assistance and Disability Evaluation units answer claims questions and rate permanent disability.

DWC lists several units here: Information and Assistance, Disability Evaluation, Audit, and the Subsequent Injuries and Uninsured Employers benefit trust funds. Information and Assistance answers rights and benefits questions for workers, employers, and others, and is often an injured worker's first DWC contact. Disability Evaluation rates permanent disability from medical reports for judges, workers, and claims administrators. DWC also runs a free injured worker Zoom workshop at 3 p.m. on the month's first Friday in English and third Friday in Spanish.

Hearing types follow DWC's statewide format. Status conferences, mandatory settlement conferences, priority conferences, and lien conferences are set on the CourtCall Video Platform. Trials, lien trials, and expedited hearings stay in person.

Can you attend by video or phone?

Yes, for most conference-type hearings. DWC moved these to the CourtCall Video Platform, and each judge's virtual courtroom link is posted on the hearing notice.

Starting March 3, 2025, DWC moved status, mandatory settlement, priority, and lien conferences to CourtCall instead of the older phone lines; each courtroom still keeps a call-in number if you need one. Trials, lien trials, and expedited hearings stay in person. Find your judge's virtual courtroom link on DWC's Virtual Courtroom Resources page, or see our guide to finding a judge's conference line and virtual courtroom link for what to have ready before you join.

How do you get there and park?

The building sits at 4th and Spring downtown, reachable by rail, bus, or car, and DWC says nearby parking is limited.

DWC's office page gives rail, bus, and car directions; use its directions and access page for the route that fits you. DWC says there is no long-term street parking nearby, and overstaying a metered space risks towing. Paid lots and structures sit near the building, though some close without notice for film shoots, and public transit is often cheaper. Rates change, so check DWC's page close to your hearing date.

What should you bring?

Bring your hearing notice and any documents it lists, and plan extra time for security screening.

The building screens visitors through a metal detector and an x-ray check, and weapons or other dangerous items are not allowed inside. DWC also says children should not come to court, and that only bottled water, not food or gum, is allowed on the ninth floor. Bring your hearing notice, photo identification, and any listed documents, and arrive early for security.

What should you do next?

Confirm your office and hearing time from your own notice, then decide whether you want a California workers' compensation attorney to review the claim.

Start with the hearing notice DWC sent you; it names your office, judge, and hearing date. Follow your notice if anything here differs. Yazdchi Law P.C. is based in Palmdale and does not keep an office at the WCAB building; this location is a state hearing site, not a firm location.

For every DWC hearing office in the state, see our California WCAB district office guide. Addresses outside the cities listed above may fall under the Van Nuys or Pomona office instead. For a California workers' compensation attorney to review your claim, call (661) 273-1780 or use the contact form. Yazdchi Law P.C. reviews each matter individually before deciding whether to take it on.
