Orange County

Which office hears your case

Two district offices, in practice by ZIP code — though § 5501.5(a) also allows the county of your attorney’s principal place of business.

If you do not drive, that difference is significant — and it is worth knowing venue is not fixed by ZIP code alone. Where a case can be filed is set by § 5501.5 — and the choice is not yours alone. The law lets the application be filed in the county where you live on the filing date, the county where the injury occurred (or, in cumulative traumaCT — Cumulative trauma Injury from repeated exposure over time. The largest injury category in California and the least claimed. and occupational disease, where the last injurious exposure occurred), or the county where your attorney’s principal place of business is, if you are represented. The law requires your written consent to the selected venue to be filed with the application. (If the attorney’s office is the one chosen, the employer may object and force one of the other two.) The DWCDWC Division of Workers’ Compensation, part of the Department of Industrial Relations. Administers the system. Information Services Center: 1-800-736-7401.’s ZIP code locator is a practical guide, not the rule.

Two offices, one county. The law names counties, and where a county has more than one office § 5501.5(b) allows the application to be filed at any Appeals Board location in that county. In practice, inside Orange County, the DWC’s ZIP code locator is what sends a case to Santa Ana or to Anaheim, and moving a filed case from one to the other takes a petition showing good cause. The options widen at the county line. Take a worker who lives in Mission Viejo and was hurt on a job in Temecula: the case can be heard in Orange County, where the worker lives, or in Riverside County, where the injury happened — and Riverside County’s office is in Riverside. Either is allowed; trials are in person at whichever office has the case.

A day in court in Orange County. Both offices run two sessions, 8:30 to noon and 1:30 to 5:00, and call cases in turn — plan on half a day, a full day for a trial. At Anaheim, check in at the front counter in Suite 170; at Santa Ana, no food or drink in the waiting room or hearing rooms. Most conferences are held by video — the link is on your hearing notice — but trials, expedited hearings and walk-throughs are in person. Santa Ana in detail · Anaheim in detail

Heat

Cal/OSHA’s July 21, 2026 heat warning named Orange County. With triple-digit temperatures expected across Southern California from July 22 to 27, heat advisories took effect for portions of Los Angeles, Orange, Riverside, San Bernardino and San Diego counties, among others.

Outdoors, the law requires shade when the temperature exceeds 80°F, and landscaping and construction are among the industries that must also follow high-heat procedures at 95°F.

Indoors — kitchens, hotel laundries, warehouses — 8 CCR § 3396 applies wherever the temperature reaches 82°F with employees present. Its full requirements, including assessment and control measures, apply at 87°F by temperature or heat index, or at 82°F for workers in clothing that holds heat in or near high radiant heat. Cool-down areas must be kept below 82°F unless the employer demonstrates that is infeasible. The rule has been in force since July 23, 2024. Heat illness claims.

What to do this week

• Get medical care, and say it happened at work. Nurses and aides: say whether lift equipment or a lift team was available, and whether a patient was violent — § 5120 and § 3342 cover both.
• Tell your employer in writing — a dated text or email — and keep a copy.
• File the DWC-1DWC-1 The claim form. Filing it starts the 90-day presumption and the $10,000 treatment obligation. claim form and keep proof of the date. That date starts the 90-day clock and the employer’s duty to authorize up to $10,000 in treatment while it decides.
