Electrical Work Built for Ontario’s Industrial Economy

Ontario sits at the center of one of the largest warehouse and distribution markets in the country. Ontario International Airport, the I-10 and SR-60 corridors and the Ontario Ranch growth area south of Riverside Drive have drawn a steady flow of big-box distribution centers, light manufacturing and flex industrial buildings. Around them sit the retail and office space of Ontario Mills, the Ontario Convention Center district and the Guasti area.

That mix creates particular electrical needs. Distribution centers run high-bay lighting across hundreds of thousands of square feet. Tenants move in and out of industrial suites and need power redistributed for new racking, conveyors, forklift charging and dock equipment. Retail and restaurant pads near the Mills need fast tenant improvements. And when a fault takes down a sort line, an operator needs an electrician who answers the phone at 2 a.m.

Left Coast Electric is a licensed commercial and industrial electrical contractor (CA #1105569) headquartered at 433 S Cataract Ave in San Dimas, a short drive west on the I-10. We have completed 50+ projects across Southern California since 2023, including a warehouse in Moreno Valley with KPRS as general contractor, which is exactly the kind of IE industrial work Ontario runs on.

Why Left Coast Electric in Ontario?

Industrial experience. Warehouse electrical is not just bigger residential work. It means three-phase distribution, large equipment loads and lighting on a much larger scale. Our Moreno Valley warehouse work and our commercial portfolio show we can deliver it.

Close to the job. Our San Dimas headquarters is close to Ontario along the I-10 corridor, so we can mobilize and respond to service calls quickly.

GC-friendly. We read the set, answer RFIs, coordinate with the other trades and close out inspections. Ask about our GC references and the full list of projects.

Nearby Cities We Serve

From Ontario we also cover the rest of the Pomona Valley and the West End: Pomona, Claremont, Rancho Cucamonga, Upland, Chino and Montclair.
