Where Business Operations Meet Reliable Electrical Power
Your commercial property’s electrical system is the backbone of your daily operations. When it functions correctly, you don’t think about it. When it fails, your business suffers — lost revenue, frustrated customers, interrupted service, and potentially unsafe conditions for employees and visitors. Fowles Electric provides expert electrical solutions for retail stores, office buildings, medical facilities, restaurants, warehouses, and multi-tenant commercial properties throughout the Inland Empire. As experienced commercial electricians, we understand that every hour without full electrical function costs you real money. That’s why we prioritize clear communication, efficient work practices, and minimal disruption to your business operations while delivering the same code-compliant, safety-focused installations that have earned our reputation.
Commercial electrical work differs from residential in almost every way — voltage levels, equipment types, code requirements, and the simple fact that you can’t just “work around” a business that needs to stay open. Our team of skilled electricians commercial specialists arrives with the training and equipment needed for commercial environments. We work with three-phase power systems, commercial lighting controls, emergency egress lighting, fire alarm integrations, and specialized equipment connections that don’t exist in homes. We’re also experienced at working around your schedule — nights, weekends, or during planned closures — so your customers and employees never experience unnecessary disruption. From small retail boutiques to large shopping centers, we adapt our approach to fit your specific business needs.




Why Choose Us
Commercial property owners and facility managers have many options for electrical services, but few deliver the combination of technical expertise, business awareness, and genuine customer care that Fowles Electric provides. We’re large enough to handle complex commercial projects — multiple crews, after-hours availability, full permitting and inspection coordination — but small enough that every client gets personalized attention from an owner who cares about their success. Our commercial electricians are trained in OSHA workplace safety, lockout/tagout procedures, and the specific codes that apply to commercial occupancies. We carry full liability insurance, workers’ compensation, and a state electrical contractor license. When you hire Fowles Electric, you’re hiring a partner who treats your business’s uptime as seriously as you do.
