Downtown Riverside, at 3737 Main Street, Suite 300, is where the state Division of Workers’ Compensation (DWC) keeps its only listed district office in Riverside County, and the city’s ZIP codes point to it. Riverside’s 92501 and 92503 through 92508 all returned it in the DWC’s ZIP code locator in October 2026.
Our office is in Newport Beach, in Orange County, and the firm takes injured workers’ cases to the Riverside district office.

Getting into the building
Every visitor checks in at the building’s security desk, signs in and shows a picture ID, and the DWC says security asks this of everyone in a group. If the district office’s floor reaches capacity, building security may ask the rest of a worker’s group to wait in the ground-floor food court until the hearing is over.
Which nearby ZIP codes go to Riverside?
The same locator returned the Riverside office for Corona (92879, 92880, 92881, 92882 and 92883) and for Moreno Valley (92551, 92553, 92555 and 92557). Corona’s ZIP codes start with 928, like many in Orange County, but the city is in Riverside County and its cases are listed for Riverside.
Live in Riverside, hurt in Orange County?
Take a Riverside resident hurt at a job in Orange County. Under Labor Code section 5501.5, residence on the filing date points to Riverside County and the place of injury (for cumulative trauma, the last injurious exposure) points to Orange County, so the Application for Adjudication of Claim, the form that opens the case, may be filed in either. With our firm as counsel, the lawyer’s-county option also points to Orange County, unless the employer objects within 30 days of receiving the information request form that names it.
How we handle Riverside cases
We read the claim papers and the medical reports, then go over where the worker lives, where the injury happened and where the case can be filed.
When we take a case on, the application goes to a county the statute allows and the client agrees to, and we handle the deadlines, the qualified medical evaluator (QME) process and every appearance. In a case filed here, conferences are held by video and a trial takes place at 3737 Main Street.
