In California, an injured worker's WCAB district is set by the worker's ZIP at the date of injury — LA County splits across five offices: Los Angeles, Pomona, Long Beach, Norwalk, and Van Nuys. Yazdchi Law, a Certified Specialist in Workers' Compensation Law firm, handles all five. Request a free case review.
Los Angeles County is geographically the largest workers' compensation jurisdiction in California — over 4,000 square miles, more than 10 million residents, dozens of major industrial corridors. The California Workers' Compensation Appeals Board splits the county across five separate district offices, and the office that hears any given case is set by where the injured worker lived on the date of injury. The five offices have different calendars, different judge rotations, and different practical experience patterns. The venue question is one of the first procedural questions an injured worker should sort out — and it is one of the most commonly mis-handled.
The five LA-County-area WCAB district offices and their seat addresses are: the Los Angeles district at 320 West 4th Street downtown (ZIPs covering downtown LA, Hollywood, Beverly Hills, and most central LA neighborhoods); the Pomona district at 732 Corporate Center Drive (ZIPs covering the Pomona Valley and the San Gabriel Valley foothills); the Long Beach district at 300 Oceangate (ZIPs covering Long Beach and the South Bay); the Norwalk district at 12440 Imperial Highway (ZIPs covering southeast LA County, including the Gateway Cities); and the Van Nuys district at 15400 Sherman Way (ZIPs covering the San Fernando Valley and the Santa Clarita Valley).
Yazdchi Law represents injured California workers statewide from a home office at 1125 W Avenue M-14 in Palmdale, with appearances at the Van Nuys, Bakersfield, Los Angeles, Long Beach, Pomona, San Bernardino, Riverside, and Oxnard WCAB district offices. Eman Yazdchi is a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California. This page lays out how the LA-County venue framework actually works, what to do if the case has been mis-routed, and how the five offices compare in practice.
The California Division of Workers' Compensation publishes a ZIP-based routing table for every California workers' compensation case. Each ZIP code maps to a single primary district office; cases at a worker's ZIP go to that office regardless of where the employer is located, where the injury occurred, or which insurer is handling the claim. The trade-off table below summarizes how the five LA-County-area offices split.
| WCAB district | Seat address | Typical ZIPs covered |
|---|---|---|
| Los Angeles | 320 West 4th Street, Los Angeles 90013 | Downtown LA, Hollywood, Beverly Hills, Mid-Wilshire, Koreatown, Silver Lake, East LA, Boyle Heights, much of central LA |
| Pomona | 732 Corporate Center Drive, Pomona 91768 | Pomona, San Dimas, La Verne, Claremont, Walnut, Diamond Bar, Glendora, Covina, much of the San Gabriel Valley foothills |
| Long Beach | 300 Oceangate, Long Beach 90802 | Long Beach, Signal Hill, Lakewood, Carson, Wilmington, San Pedro, Harbor City, much of the South Bay |
| Norwalk | 12440 Imperial Highway, Norwalk 90650 | Norwalk, Whittier, Downey, Pico Rivera, Bellflower, Cerritos, Lakewood (split), Cudahy, Bell Gardens, much of the Gateway Cities |
| Van Nuys | 15400 Sherman Way, Van Nuys 91406 | Van Nuys, North Hollywood, Sherman Oaks, Encino, Northridge, Granada Hills, Reseda, Burbank-adjacent areas, much of the San Fernando Valley and Santa Clarita Valley |
It happens regularly — a claims examiner files an Application for Adjudication of Claim at the office near the employer rather than the office that controls the worker's ZIP. The worker (or counsel) can file a Petition for Change of Venue at the WCAB asking that the case be transferred to the correct district under the DWC's ZIP-routing rules. The petition typically attaches the worker's residential address at the date of injury and the DWC ZIP table entry showing the correct office. Venue changes are routinely granted when the petition shows a clean ZIP mismatch. The DWC WCAB district directory lists each office's contact information.
All five California WCAB district offices apply the same Labor Code, the same AMA Guides 5th Edition impairment rules under California Labor Code §4660, the same California Labor Code §4663 apportionment standard, and the same California Labor Code §5903 reconsideration framework. The day-to-day differences are operational. The Los Angeles district downtown handles the highest case volume and tends to have the most experienced judges on contested medical-legal records. The Van Nuys district handles the heavy SFV/SCV docket including a large entertainment-industry claimant population. The Pomona district handles the foothills, with a steady manufacturing and logistics docket. The Long Beach district handles the South Bay and Port of Long Beach claimants — including longshore, container, and shipping-yard claims. The Norwalk district handles the Gateway Cities — including aerospace, healthcare, and logistics-corridor claims.
Under DWC ZIP-routing rules, the operative ZIP is the worker's residence at the date of injury — not at filing, not at the present day. A worker who lived in the Norwalk district on the date of injury but has since moved to Riverside still has the case heard at Norwalk unless a Petition for Change of Venue is granted on convenience grounds. A worker who moved out of state can usually keep California jurisdiction under California Labor Code §3600 as long as employment was in California, and the case stays at the original district. A specialist evaluates the venue posture at the start of every case.
A California cumulative trauma claim under California Labor Code §3208.1 that involved multiple employers across multiple ZIPs is governed by the worker's residence at the last day worked under California Labor Code §5500.5 — the last-injurious-exposure rule — for jurisdictional purposes, but venue follows the worker's residential ZIP. A worker who cumulatively injured a shoulder across three employers in three districts files at the office for the worker's residence at the date of injury, and California Labor Code §5500.5 controls which insurer pays. The two rules — venue and liability allocation — are distinct.

Tap to call →Before any venue argument, confirm which ZIP the worker actually lived at on the date of injury. The address on the DWC-1 should match the address on the driver's license at the time. If the worker has moved between the date of injury and the present day, the operative ZIP is the earlier one. The DWC ZIP-routing table maps that ZIP to a single district office, and that office is where the case belongs — even if the worker's current employer or current address would suggest a different office.
If the Application for Adjudication of Claim has been filed at the wrong district, the worker (or counsel) files a Petition for Change of Venue. The petition states the worker's residential address at the date of injury, attaches the DWC ZIP-routing table entry, and asks the WCAB to transfer the case to the correct district office. Venue changes are routinely granted when the ZIP mismatch is clean. The DWC WCAB district directory lists each office's contact information.
