Construction is California’s most dangerous industry. When you’re injured, experience matters.
By Eman Yazdchi, Esq. · Certified Specialist in Workers' Compensation Law, State Bar of California Board of Legal Specialization
In California, a Chatsworth construction worker injured on an Aerojet Rocketdyne expansion, a 118 Freeway warehouse tilt-up, or a Devonshire commercial build recovers medical care, lost wages, and a permanent disability rating, plus a §4553 50% penalty for known-hazard violations. Yazdchi Law — a Certified Specialist workers' comp firm in Palmdale — handles SFV construction. Free consultation.
Construction injuries in Chatsworth cluster around four site types. Aerojet Rocketdyne and the broader Chatsworth aerospace-defense corridor facility expansions and tenant-improvement work — Mahle Industries, Lockheed Martin legacy facilities, and the supply-chain machine shops — produce confined-space, overhead-steel, struck-by, and electrical injuries inside active manufacturing floors. The 118 Freeway warehouse and distribution build-out — tilt-up panel construction, racking installation, and dock-leveler work — produces falls from elevation, crush injuries from tilt panels, and struck-by injuries from material-handling equipment. The Devonshire / De Soto / Topanga commercial corridor build-out produces retail-tenant-improvement falls, lacerations, and electrical injuries. And the Plummer / Lassen light-industrial belt produces tilt-up, racking, and HVAC injuries.
The OSHA Fatal Four — falls, struck-by, electrocutions, and caught-in/between — accounted for 39.2% of all construction fatalities in 2022, according to the U.S. Occupational Safety and Health Administration, and these four mechanisms drive the most serious Chatsworth construction claims.
Yazdchi Law's Palmdale office at 1125 W Avenue M-14 sits roughly 40 miles north of Chatsworth — about a one-hour drive along the 14 Freeway and 118; the firm appears at the Van Nuys WCAB constantly, the same district that hears every Chatsworth case. Eman Yazdchi is a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California. Chatsworth construction cases are heard at the Van Nuys district office of the Workers' Compensation Appeals Board at 6150 Van Nuys Boulevard, Van Nuys.
A Chatsworth construction-injury claim is shaped by the layered GC / subcontractor / staffing-agency structure that defines aerospace-facility and SFV warehouse construction, frequent Cal/OSHA citations after a serious incident, and the parallel third-party claim against equipment manufacturers, premises owners (Aerojet Rocketdyne, warehouse owners), or other on-site contractors. This page sits within our broader California construction-injury attorney practice.
Under California Labor Code §4600, the employer must provide all medical treatment reasonably required to cure or relieve the injury — emergency care, imaging, orthopedic and neurosurgical specialist evaluation, surgery, rehabilitation, and durable medical equipment. Treatment is screened through Utilization Review under California Labor Code §4610 against the Medical Treatment Utilization Schedule, and a UR denial of advanced imaging or surgery is appealed through Independent Medical Review within 30 days under California Labor Code §4610.5. Independent Medical Review overturns roughly 10–15% of California Utilization Review denials, according to California Division of Workers' Compensation reporting (as of 2026).
Under California Labor Code §4553, when a Chatsworth employer knew of a dangerous condition — missing fall protection on a 118 Freeway warehouse tilt-up, unshored trench on a Devonshire commercial build, ungrounded equipment on an Aerojet Rocketdyne sub job — and deliberately failed to fix it, the worker's permanent disability award is increased by 50%. Cal/OSHA Title 8 safety orders — Title 8 §1670 (personal fall arrest), Title 8 §1541 (trench shoring), Title 8 §3203 (Injury and Illness Prevention Program) — anchor a California Labor Code §4553 finding. California Labor Code §6400 (the General Duty Clause of Division 5) sets the umbrella employer duty. Statute deep-dive: California Labor Code §4553 (serious-and-willful misconduct).
Under California Labor Code §2810, a person or entity may not enter a construction labor contract if it knows or should know the contract lacks funds sufficient for the contractor to comply with wage, workers' comp, and other labor-law obligations. The rule is the lever for chasing a Chatsworth GC or staffing agency that funneled hazardous work to an under-capitalized sub on an Aerojet Rocketdyne facility expansion or a 118 Freeway warehouse tilt-up. Where the sub turns out to be uninsured, California Labor Code §3706 strips the exclusive-remedy defense and opens a civil action against the employer. The licensed-contractor rebuttable employee presumption under California Labor Code §2750.5 is the companion lever for 1099 misclassification.
California Labor Code §3700 requires every California employer to carry workers' compensation insurance; California Labor Code §3700.5 makes failure a misdemeanor; California Labor Code §3706 strips the exclusive-remedy bar from an uninsured Chatsworth employer — opening a civil action for pain-and-suffering, full lost wages, and damages outside the comp framework, in addition to filing against the Uninsured Employers Benefits Trust Fund.

Tap to call →Chatsworth construction-injury cases are heard at the Van Nuys district office of the Workers' Compensation Appeals Board at 6150 Van Nuys Boulevard, Van Nuys. The Division of Workers' Compensation publishes the district directory. Yazdchi Law appears at Van Nuys constantly for SFV construction claims including California Labor Code §4553 serious-and-willful petitions on aerospace and warehouse builds. Related coverage: Chatsworth denied workers' comp claims.
Settlement magnitudes vary widely with severity, body parts, and the California Labor Code §4553 / California Labor Code §3706 overlay. A clean lumbar herniation from a Devonshire tenant-improvement fall with full recovery resolves in the mid-five figures. A multi-level spinal fusion with permanent restrictions on a 118 Freeway warehouse tilt-up resolves in the low to mid six figures plus future medical care under California Labor Code §4600 and a Supplemental Job Displacement voucher under California Labor Code §4658.7. A catastrophic Aerojet Rocketdyne facility-expansion fall with spinal cord involvement, combined with a California Labor Code §4553 finding and a California Labor Code §3706 civil action against an uninsured employer, can resolve well into seven figures. The firm's historical case-result range across catastrophic injuries reaches $5,000,000. Related coverage: Chatsworth workers' comp claims.
