About
With 500+ completed commercial and industrial projects and 25+ years of field experience, DSP Electrical Contractors delivers full-service C-10 electrical contracting across Los Angeles, Riverside, and San Bernardino counties from their base in the Inland Empire. For facility managers and property owners overseeing office buildings, healthcare facilities, hospitality properties, institutional campuses, and government public works sites, DSP offers a single-source partner capable of handling every phase from underground dry utilities and site work through complex medium voltage systems and power distribution. The company self-performs all trades with its own licensed workforce — a critical distinction for facility managers who need accountability and schedule control on occupied or mission-critical buildings. Core capabilities include service upgrades, switchgear and panelboard work, standby power and emergency generator systems, lighting and control systems (including sports and site lighting), fire alarm, low-voltage tele/data/fiber cabling, CCTV/security, access control, and public address systems. DSP also holds in-house design-build and design-assist capability, allowing facility and construction managers to engage them early in project development to optimize electrical systems for cost and code compliance under California NEC requirements. LEED-certified project experience makes DSP a qualified partner for sustainability-driven owners pursuing green building goals. Verified credentials include California C-10 Electrical Contractor License #928856, California DIR registration #1000013287, and ABC (Associated Builders & Contractors) membership — giving procurement teams the compliance documentation needed for public works and institutional bids. Serving a 100-mile radius from Corona, CA, DSP is well-positioned to support multi-site facility portfolios across the greater Southern California region. Completed projects span church campuses, public health facilities, and municipal parks, demonstrating range across both private and public sector clients.
