A San Dimas Electrical Contractor Built for GCs, Developers & Facility Managers
When your schedule depends on the electrical sub, you need a contractor who reads the drawings, answers RFIs and closes out inspections. Left Coast Electric is a licensed commercial and industrial electrical contractor headquartered at 433 S Cataract Ave in San Dimas. We work with general contractors, developers, property managers and facility teams across the San Gabriel Valley, from bid review through final inspection.
Who we work with:
- General contractors and developers. Clear bid pricing, responsive RFIs, coordination with the other trades, and crews that work to your schedule.
- Property managers and commercial landlords. Suite turns, tenant buildouts, code corrections and service calls in occupied buildings.
- Industrial and warehouse operators. Power distribution, equipment feeds and capacity upgrades planned around production.
- Retail, office, hospitality and mixed-use owners. Buildouts and upgrades phased around your business hours.
Our crews mobilize from Cataract Ave to projects in the San Dimas Industrial Park, along the Arrow Hwy corridor, and in neighboring Glendora, La Verne, Claremont, Covina and Pomona.

Why a San Dimas Headquarters Matters on Your Project
- Local mobilization. Our crews, trucks and materials are based on Cataract Ave, so a San Gabriel Valley job site is a short drive, not a cross-county commute.
- Local permitting know-how. We work with San Dimas and neighboring SGV building departments and plan inspection sequencing into the schedule from day one.
- One accountable team. The same Left Coast Electric crews handle commercial and industrial scopes, from pre-construction through closeout, and keep your PM informed at every step.
- 24/7 emergency service. When a breaker, panel or feeder fails in an occupied building, call (877) 960-1122 any time, day or night.
- Licensed and local. We’re a California-licensed electrical contractor (#1105569) headquartered right here in San Dimas.
Out-of-area contractors lose time to travel and unfamiliar jurisdictions. Our team is based right here.
