What McMillan Electric does

McMillan Electric is a privately held, locally owned commercial electrical contractor founded in 1965 and headquartered in San Francisco at 1480 Folsom Street, with additional offices in Belmont, CA and Reno, NV. The firm serves enterprise clients across commercial, industrial, life sciences, healthcare, and technology markets in Northern California and northern Nevada, operating through enterprise field sales targeting building owners, property managers, general contractors, architects, and developers. Marquee clients include Google, Blue Shield, Autodesk, GitHub, Allogene Therapeutics, and Cushman & Wakefield, with project footprints ranging from 55,000 to 475,000 square feet.

The company's core technology stack centers on Building Information Modeling (BIM) for preconstruction planning, off-site production (OSP) prefabrication, design-build and design-assist delivery, low-voltage systems integration, and renewable energy systems. Operations are structured across four integrated service divisions: Electrical Construction (new builds, tenant improvements, specialty construction, and life sciences projects), Renewable Energy Systems (solar PV, battery energy storage, EV charging, and project development under the McMillan Renewable Power Systems brand), Low Voltage Systems (data infrastructure, structured cabling, AV, security/access control, and cyber security under the MNetworks brand), and Phase One Fire Life Safety Systems. Supporting offerings include a 24/7 All-Hours Service Department for emergency response and preventative maintenance.

McMillan Electric generates revenue primarily through project-based professional services contracts for commercial and industrial electrical work, with pricing determined per project based on scope and specifications rather than through publicly disclosed pricing tiers. The firm operates exclusively through direct sales channels without intermediaries, emphasizing collaborative partnership and repeat business with major clients. Complementing construction revenue are ongoing streams from service and maintenance contracts, design-build engagements, hardware-adjacent renewable energy installations, and 24/7 emergency response engagements. The workforce comprises 350+ employees including IBEW-certified electricians across six local union chapters, supporting 4M+ square feet of annual construction volume.
