Mechanical and body shops carry real workers' comp exposure — lifts, solvents, paint booths, and heavy lifting. We place California auto repair and collision shops with the right carrier at the right rate, and split your payroll so you're not overpaying on office and sales staff.
Who We Cover
From independent mechanical shops to collision and body shops, tire, muffler, and transmission shops, WPIS writes workers' comp for California auto repair businesses of every size. Whether you run a single bay or a full service center, your coverage is built around how your shop actually runs.
Auto repair sits in the mid-to-high range for workers' comp, and body shops with paint and solvent exposure run higher than mechanical-only shops. Lifts, presses, hand tools, and chemical handling all drive loss costs. We lower your premium three ways: splitting your payroll correctly so service writers and office staff aren't rated as mechanics, managing your X-Mod proactively, and marketing your account to carriers that actually want auto risk.
A California workers' compensation policy pays for work-related injuries regardless of fault. For an auto shop that means medical care for lifting injuries, burns, lacerations, and chemical or solvent exposure; lost wages while a worker recovers; occupational-illness claims from paint and fumes; and employer's liability if an injury leads to a lawsuit. Coverage is required for virtually every California auto shop with employees — there is no payroll threshold.
Class Codes
Your class code drives your rate, and auto shops almost always qualify for more than one. Getting the split right — especially keeping office and sales staff out of the shop code — is one of the biggest levers on your premium. These are common examples; we confirm the exact classification for your operation:
| Class Code | Operation | Hazard Profile | Notes |
|---|---|---|---|
| 8389 | Auto Repair / Service (mechanical) | Medium | General repair, tires, brakes |
| 8393 | Auto Body & Paint (collision) | Higher | Body work, paint, solvents |
| 8742 | Outside Sales / Service Writers | Low | Often split out of the shop code |
| 8810 | Clerical / Office | Low | Keep office staff out of the shop code |
Service writers, parts counter, and office staff shouldn't be rated as mechanics. Misclassification is the most common overcharge we find in auto shops — we audit your split at every renewal.
We track open claims, push for timely closure, and verify the data WCIRB uses to calculate your mod. Catching errors early keeps your rate down.
Lift inspections, ventilation and respirator programs for paint, and lifting and ergonomics training reduce claims — and carriers price safety in.
Auto risk isn't written the same by every carrier. We run a full market comparison each year so carriers compete for your business instead of renewing you on autopilot.
FAQ
Is workers' comp required for my auto shop in California?
Yes. Any California business with employees must carry workers' compensation — there is no minimum payroll or headcount that exempts you.
Do body shops pay more than mechanical shops?
Usually yes. Paint, solvents, and collision work carry higher rates than mechanical-only repair. Correct classification and a documented safety program are the best ways to keep a body shop's premium in check.
Can I split my office and sales payroll out of the shop rate?
Yes — and you should. Service writers, parts, and clerical staff belong in lower-rated codes. We make sure your payroll is reported correctly so you're not overpaying.
Can I get covered with prior claims or a high X-Mod?
Yes. We work with carriers that specialize in tougher auto accounts, including shops other brokers have struggled to place.

Auto repair shops fall under California class code 8389 (Automobile or Truck Repair Facilities, no retail gasoline sales), which covers mechanical repair such as engines, brakes, electrical, air conditioning, and exhaust. Auto body and paint work falls under 8393, and transmission specialists under 8397, so correct classification keeps your premium accurate.
Injury frequency from lifts, hand tools, solvents, and slips, plus your claims history and X-Mod. A clean safety record and a low X-Mod are the main ways to reduce cost.
Maintain a safety program, manage claims quickly, confirm your class codes, separate clerical and parts-counter payroll where allowed, and let a broker market your account competitively.
