Santa Rosa WCAB District Office

This Santa Rosa WCAB office sits at 50 D Street, Room 420, in downtown Santa Rosa, and it hears disputed California workers' compensation claims venued in Sonoma and Napa counties.

The California Division of Workers' Compensation, or DWC, lists these details for its Santa Rosa district office, checked October 14, 2026:

• Address: 50 D Street, Room 420, Santa Rosa, CA 95404-4771
• Phone: 707-576-2391
• Court session hours: 8:30 a.m. to 12:00 p.m. and 1:30 p.m. to 5:00 p.m.
• Lobby hours: Monday through Friday, except holidays, 8:00 a.m. to 5:00 p.m.

The Workers' Compensation Appeals Board, or WCAB, is the state court that decides contested workers' comp claims. A "district office" is simply the local courthouse and filing counter DWC assigns to a group of ZIP codes. Yazdchi Law P.C. is based in Palmdale and has no office in Santa Rosa. Call (661) 273-1780 or use the contact form if you want the firm to look at a Sonoma or Napa County claim. The firm reviews each matter individually.

Which Sonoma and Napa claims go to Santa Rosa?

A claim lands in Santa Rosa when Labor Code section 5501.5 places venue in Sonoma or Napa County, not simply because a ZIP code search points there.

DWC's ZIP code locator shows which district office handles most filings for a five digit ZIP code. It is a helpful starting point, but it does not set venue for an actual case. Under California Labor Code section 5501.5, an application for adjudication of claim is filed in the county where the injured worker lives on the filing date, the county where the injury or last harmful exposure happened, or the county where the worker's attorney keeps a main office. When a county has more than one appeals board location, the filing goes to whichever location fits those same rules, with the worker's written consent.

In practice, Sonoma and Napa County claims are usually filed at this office. Our existing city guides cover these two:

• Santa Rosa
• Napa

If your hearing notice names a different office, follow the notice. The notice, not the locator, confirms where your own case is actually set.

What happens at the Santa Rosa WCAB office?

DWC holds Workers' Compensation Appeals Board hearings here, alongside an Information and Assistance Unit, a Disability Evaluation Unit, and a monthly workshop for injured workers.

DWC's page for this location lists a Disability Evaluation Unit and an Information and Assistance Unit among its units. The unit gives free help to workers, employers, and other parties about rights, benefits, and procedures under California workers' compensation law. DWC calls it an injured worker's usual first contact; reach it at (707) 576-2452, or call the statewide Information Services Center at 1-800-736-7401. DWC also holds an injured-worker workshop by Zoom at 3 p.m. on the first Friday of each month in English and the third Friday in Spanish.

Filings can be date stamped at the front counter in Room 420 during lobby hours. For what a specific hearing covers, read the notice DWC or the claims administrator mailed you.

Can you attend a Santa Rosa WCAB hearing by video or phone?

Most conference hearings now run on DWC's CourtCall Video Platform instead of a phone line; trials still happen in person.

DWC's Virtual Courtroom Resources page explains that, starting March 3, 2025, status conferences, mandatory settlement conferences, priority conferences, and lien conferences moved from telephone lines to the CourtCall Video Platform. Trials, lien trials, and expedited hearings continue to be set in person. Each judge keeps a separate virtual courtroom, and DWC says access information is posted on its site and printed on hearing notices. Each courtroom also keeps a call-in number on hand if needed.

This page does not list a judge's conference line or access code, since DWC assigns those per case and they change. Use the link printed on your own hearing notice, or check the Virtual Courtroom Resources page directly.

How do you reach the Santa Rosa office, and is there parking?

The office is in the Joseph Rattigan state building on D Street; DWC points visitors to a nearby city garage and metered street parking.

DWC's listing says a City of Santa Rosa parking garage sits directly across D Street from the building entrance, with all-day parking at $0.75 per hour and an $8 per day maximum. Metered parking is also available on D Street and Second Street. DWC also names Santa Rosa City Bus, Sonoma County Transit, and Golden Gate Transit as transit options. Confirm current driving directions and any posted rules on DWC's page before your visit.

What should you bring to a hearing at the Santa Rosa office?

Bring your hearing notice, a photo ID, and your own copies of the key claim documents, and follow whatever the notice itself instructs.

Start with the notice that told you about the hearing; it lists your case number, date, time, and format. Bring a photo ID, that notice, your claim correspondence, and your medical and work-status records. If the notice lists a video or phone format, follow the access steps on it. If it lists an in-person session, arrive early enough to park and find Room 420.

Next steps for a Sonoma or Napa County claim

Confirm your hearing details on your own notice first, then decide whether you want a lawyer to review the claim before your date at this office.

Your hearing notice carries your case number, date, and format. Save a copy, note any deadline, and keep your medical and claim records together. DWC's I&A Unit can explain a notice or form, but it does not represent either side.

Yazdchi Law P.C. is based in Palmdale and keeps no office in Santa Rosa or Napa. Call (661) 273-1780 or use the contact form to ask whether the firm can review a workers' compensation matter venued at this office. The firm looks at each case individually and does not take every matter.
